Multiple times each week, I ease my car into a parking spot and tuck my cloth grocery bags under my arm before dashing into Trader Joe’s to stock up on staples. After nearly a year, my list permanently etched itself onto my brain: bananas, Brussels sprouts, spinach, eggs… I quickly navigate through the store, deftly weaving in between other leisurely browsing customers, and always end my trip by standing in the shortest line with the best selection of dark chocolate bars.
Last fall, that particular cash register was usually operated by a tall college kid with long brown dreadlocks. Full of positivity and smiles, he energetically asked each customer how they were doing and whether they had plans for the evening. On one rather busy afternoon, I replied that I set aside a few hours to bake muffins and 2 types of cookies.
“Really?” He looked startled. “What kinds?”
After I answered, he responded, “Well if you need a taste tester, I’m here ’til 10!” with a huge grin on his face. I laughed, agreeing to stop by again if the treats turned out nicely, but… I jinxed it with my promise. None of those baked goodies tasted decent enough to share!
A couple weeks later, I finally perfected the recipe for my toffee coffee cookies, and after devouring half the batch, I packed up the rest in a zip-topped baggie and slid them into my purse. Over at TJ’s, I handed the cookies to that employee along with the cash for my produce purchases and watched his eyes light up like a toddler’s on Christmas morning.
“Whaa… You baked me cookies??” he sounded awestruck. “Oh my gosh—thank you! This is, like, the best day ever!”
I laughed as he stared at them. “What flavor are they?” he asked. When I responded, he bounced up and down in a makeshift happy dance, while his jealous coworkers begged for a taste. It turned out everyone there adored coffee! He then walked around the counter and buried me in a huge bear hug before I left with my groceries.
But since that October afternoon, I hadn’t ever seen him there again, and my slightly paranoid mind started to worry. What if there’s some rule against taking stuff from customers? What if he was fired all because I gave him cookies??
As the weeks and months dragged by, I gradually began to forgive myself for him losing his job, and I stopped thinking about the incident whenever I pulled into the parking lot.
This past Saturday morning, I begrudgingly canceled my morning run due to the gruesome windy storm blowing through the West Coast, loading up my bags and heading over to TJ’s for my biweekly shopping spree instead. As I waited in line for the sweet girl to ring up my groceries, I glanced up at the employee station and did a double take. The dreadlock kid stood there with his back to me, chatting with the store manager!
He didn’t get fired! I didn’t make him lose his job after all!
That one fleeting moment—simply spotting the dreadlock cashier—completely brightened my rainy day, much like the sunshiny flavors in this Lemon Poppy Seed Loaf Cake. Full of fresh tangy notes, this citrus dessert even boasts a sweet almond glaze, giving it a highly sophisticated taste despite being astonishingly simple to make!
I polled the AHB Facebook page last month, asking what types of cakes you enjoyed baking. I basically received the same response from everyone: you save layered cakes for special occasions and prefer easy, one-pan cakes for everything else. So that’s exactly what I created—a simple loaf cake baked in a standard 9” x 5” pan. And you don’t even need to pull out your electric mixer for any of it!
I loaded lots of lemon flavor into this low fat cake. You’ll use both lemon zest and lemon juice. The zest actually provides most of the flavor, while the juice reacts with the baking powder to keep the cake light and airy. Make sure you use fresh lemons; the flavor of bottled lemon juice or lemon extract tastes more artificial.
After my childhood love affair with lemon poppy seed muffins (they were the only flavor I’d ever eat!), I always add in plenty of poppy seeds to my citrusy baked goods. The loaf looks so cute with their tiny blue speckles! They also add a subtle earthiness to balance out the bright lemon, but if you aren’t a fan, feel free to decrease the amount of (or completely omit) the poppy seeds.
To lighten this lemon cake, I only mixed in 1 tablespoon of oil. The rest of the tender texture comes from Greek yogurt! A true powerhouse in low fat baking, it contributes tons of moisture without the excess fat and calories. (It also adds a little extra protein too, so I sneak it into almost all of my baked treats!) If you don’t have Greek yogurt, regular yogurt will work just fine.
Like a stereotypical cake recipe, mine requires you to alternate adding the dry ingredients and milk to the egg mixture. Alternating additions is mandatory. This reduces the chance of over-mixing the batter, which would over-develop the gluten strands and turn your cake tough. So let’s avoid dry cake! Simply stir in 1/3 of the flour mixture until just barely incorporated; then gently mix in half of the milk. Repeat again, and finish off by folding in the last 1/3 of the flour. This easy method ensures your cake stays light and airy every time!
After popping the pan in the oven, come back and check on it after about 30 minutes. Sometimes loaf cakes brown a little too quickly on top, and the bottom hasn’t cooked all the way through by the time the top looks done. If that happens to you, pull out the pan and place a little tin foil tent over the top before sticking it back in the oven to finish baking.
As difficult as it sounds, you must let the cake cool completely before glazing it. (Although to be honest, the glaze is optional… Without it, you could easily treat this loaf as a healthy breakfast slice!) I included options for both almond and vanilla glazes. While I prefer almond—it’s my all-time favorite flavor!—my guy absolutely hates it, so I drizzled his with the vanilla instead. If you choose the vanilla route, use clear vanilla extract to preserve the glaze’s bright white color. Walmart sells a large 4 oz bottle in their wedding section for a great price!
After all of your patient waiting and decorative drizzling, you’ve completely earned your reward: a thick slice of this skinny Lemon Poppy Seed Loaf Cake! The tangy citrus really sings in each tender bite, pairing perfectly with the earthy little seeds and sweet white glaze. With its vibrant flavor and moist texture, this easy cake will always brighten anyone’s day!
So you probably know my guy by now… He basically avoids every dessert I bake, preferring candy like fruity gummy worms and colorful sweet tarts instead.
The morning after this cake’s photo shoot, my guy wandered into the kitchen while I edited the pictures in the office. When I heard the quiet whisper of peeling open plastic wrap, I tiptoed down the hall to peer around the corner, spying as he carved off a huge 2”-thick slab. And he finished off the entire thing—every last crumb!
That’s the biggest compliment I could ever ask for, and you better believe that it completely brightened my day too!
And when you make your own, remember to snap a picture and share it on Instagram using #amyshealthybaking and tagging @amyshealthybaking IN the photo itself! (That guarantees I’ll see your picture! 🙂 ) I’d love to see your lemon poppy seed loaf cake!

Lemon Poppy Seed Loaf Cake
Ingredients
FOR THE CAKE
- 2 cups (240g) all-purpose flour (measured like this)
- 2 tbsp (18g) poppy seeds
- 1 ½ tbsp (10g) lemon zest (about 3 small or 1 extra large)
- ¾ tsp baking powder
- ¾ tsp baking soda
- ¼ tsp salt
- 1 tbsp (15mL) canola or vegetable oil
- 1 large egg, room temperature
- 1 tbsp (15mL) vanilla extract
- ⅔ cup (128g) granulated sugar
- ½ cup (120g) plain nonfat Greek yogurt
- 2 tbsp (30mL) fresh lemon juice (about 1-2 small)
- 6 tbsp (90mL) nonfat milk
FOR THE GLAZE
- 4 tbsp (30g) powdered sugar
- ¼ tsp almond extract
- 1 tsp nonfat milk
Instructions
- Preheat the oven to 350°F, and lightly coat a 9x5” pan with nonstick cooking spray.
- To prepare the cake, whisk together the flour and next 5 ingredients (through salt) in a medium bowl. In a separate bowl, whisk together the oil, egg, and vanilla. Mix in the sugar, yogurt, and lemon juice until thoroughly incorporated. Alternate between adding in the flour mixture and milk, beginning and ending with the flour. (For best results, add ⅓ of the flour, then ½ of the milk, etc.)
- Pour the batter into the prepared pan, and bake at 350°F for 40-45 minutes. If the top browns too quickly, cover the pan with a tent of tin foil after the first 30 minutes. Cool in the pan for 10 minutes before turning out onto a wire rack to cool completely.
- To prepare the glaze, whisk together the powdered sugar, almond extract, and milk in a small bowl. Drizzle over the top of the cooled cake.
Notes















I’d like to make this, but I don’t understand alternating the milk. Does the milk get mixed in with the yogurt or does the milk remain on its own (6T) and alternated in?
Thanks for your help.
The milk remains on its own; it does not get mixed in with the yogurt. After the first 3 sentences of Step 2, you should have 3 bowls: one with the egg mixture, one with the flour mixture, and one with the milk. Add 1/3 of the flour mixture to the egg mixture followed by 3 tablespoons of the milk to the egg mixture. Repeat that again, and then finish with the last 1/3 of the flour mixture. Hope that helps Elaine! 🙂
This looks delicious! Is it really an entire tablespoon of vanilla extract?
Thanks Bri! Yes, it is an entire tablespoon of vanilla extract. Extra vanilla imitates butter’s flavor without the extra fat and calories! One of my favorite healthier baking tricks. 🙂
I just cut into the lemon poppy seed loaf. Very good! I think I should have added more lemon juice; will modify it next time.
Will write again once my co-workers give their unbiased opinion. Great thing about friends — they always tell you the truth no matter what.
I made this bread last night my family liked it but it was a little dry. Any suggestions?
I’m sorry Suzanne; that must have been disappointing! Make sure you use a light hand when measuring flour with the spoon-and-level method. (Check out my Baking Basics for more details!) Too much flour would dry out the loaf. If that wasn’t the problem, then try adding an extra 2-3 tablespoons of Greek yogurt and an extra 1 tablespoon of milk. Hopefully that helps! 🙂
This looks so delicious! I want to make it for my family for Easter! I like to use natural sugars when possible. Do you think I could use maple syrup in place of the sugar? Or coconut sugar?
Thank you!!!
Thanks Virginia! I’d advise against maple syrup because it has its own distinct taste that could overwhelm the lemon. I haven’t tried any natural sugars though, so I’m not entirely sure how they’d turn out. I’m guessing that if you use a solid natural sugar, as opposed to a liquid, it’ll probably work fine. 🙂 Have a lovely Easter with your family!
Thanks for your quick response, Amy! I’ll try a natural, solid sugar and let you know how it turns out! Have a wonderful Easter as well! 🙂
You’re welcome Virginia! I’m excited to hear how the cake turns out for you. If you enjoy your version with the natural solid sugar, I’d love to be able to include your substitution in the Notes section beneath the recipe! 🙂
Hi Amy! Here’s my update! I made the cake this weekend with these changes:
I used all white whole wheat flour, organic cane sugar from Whole Foods, goat’s milk yogurt (I’m sensitive to cow’s milk) and refined (neutral-tasting) coconut oil for the oil. I also made more glaze and added my favorite raspberry jelly to it!
I cooked it 40 minutes until golden brown and served it with the glaze on top, fresh raspberries and French vanilla coconut milk ice cream. With the glaze and ice cream (on top!) it was a bit hit! The cake itself was a bit drier than I had hoped but I think I cooked it a few minutes too long and will also add a bit more milk/yogurt next time. The flavor was amazing and very lemony! Thanks for this great recipe!!
Thank you SO much for all of your changes Virginia! I’m really happy to hear that the white whole wheat flour and organic cane sugar worked. That sounds like a magical twist with the raspberry jelly; I’m definitely keeping that in mind for next time! So happy you and your loved ones enjoyed it!! 🙂
Can I substitute the Greek yogurt? I don’t have any type of yogurt or sour cream. Thanks
I haven’t tried baking this cake with anything other than the Greek yogurt, and I don’t really recommend substituting anything other than another type of yogurt (regular, non-dairy, etc.) because it adds a lot of moisture and results in a tender crumb. If you really wanted to try, applesauce might work, but because I haven’t tried that swap myself, I’m not 100% sure.
Hi Amy!
I’ve just discovered your site and can’t wait to start trying your recipes – this one is on the top of my list! I wonder if you think I could substitute coconut flour or if it would impact the texture? I haven’t used coconut flour in baking before but I’d like to try it… Just unsure if it reacts the same as white flour? Do you have any thoughts on it?
Thanks so much!
I wouldn’t recommend using pure coconut flour in this recipe. Coconut flour is actually 3 times as absorbent as regular flour! (So for 1 cup of all-purpose, you’d use around 1/3 cup coconut flour.) Also, coconut flour lacks gluten, which provides structure to baked goods, so this cake would probably fall flat unless you added xanthan gum (a GF ingredient that imitates gluten’s elastic structural properties). If you haven’t baked with coconut flour before, I’d recommend starting by trying a few recipes where it’s already in the ingredient list so you can begin to get a feel for how it works. Hope this helps! 🙂
Just made this today and it turned out PERFECT! Never tried anything with poppy seeds and lemon before so was a bit nervous about the taste but it’s so light and fluffy and doesn’t give you that heavy feeling after eating something chocolately! Only a little bit left as the fam loved it too so definitely not losing this recipe, thanks!!
I’m so happy that you and your family enjoyed the loaf cake! That’s a huge compliment that there isn’t much left. I can definitely relate to the chocolate vs. citrus feeling too; as much of a chocoholic as I am, there are still times where it’s a teensy bit too heavy! 😉
