I’m partnering with Bob’s Red Mill® to bring you today’s recipe! I absolutely love their healthy, top-quality products (flours, oats, protein powders, and more!). They ensure my recipes turn out perfectly and taste delicious every time I make them!
Throughout my childhood, my grandma occasionally flew out to California to visit us. We drove to the airport to pick her up, parked in the short-term lot, and walked all the way to her gate to greet her. (This was ages ago before all of the 21st century airport security measures!)
Once we exchanged hugs, we headed for baggage claim to pick up her suitcase, and we carefully wheeled it out to the car. Back at home, Dad carried it up the stairs to the guest bedroom, and I eagerly bounced around in the hallway, waiting for Grandma to unzip it…
Because she often packed two homemade loaves of zucchini bread for us! Even though it had weird “green things” inside (I was a huge picky eater as a young girl!), the cinnamon and nutmeg and sugar masked their taste… And the texture was so moist and tender, just like pound cake!
Since it was technically called a “quick bread,” even with massive quantities of oil and sugar hiding inside, Mom let us eat slices as afternoon snacks. I often asked for seconds, and the first loaf always seemed to disappear by the time we drove Grandma to the airport for her return flight!
Looking back, I realized that particular zucchini bread probably should’ve been classified as dessert… But not this healthy zucchini oatmeal snack cake! With plenty of oats and no refined sugar, it’s definitely healthy enough for snacking — and even breakfast! Yet it still has the same irresistible spice flavors and supremely moist texture as those loaves from my childhood…
Which means this cake disappears just as quickly too! 😉
KEY INGREDIENTS TO MAKE A HEALTHY ZUCCHINI OATMEAL SNACK CAKE
Let’s go over what you’ll need to make this healthy zucchini oatmeal snack cake!
You’ll start with a combination of Bob’s Red Mill whole wheat flour (this kind!) and Bob’s Red Mill quick cooking oats (these ones!). Bob’s Red Mill products are huge staples in my pantry because they’re top quality and taste amazing — and they’re so dependable and affordable! With how many different flours and oats and grains that I use, I could probably single-handedly keep Bob’s Red Mill in business…
But getting back to those oats! They’re the key to this snack cake, both in texture and nutrition, so it’s important to use the correct kind. Quick cooking oats are also called “one-minute” or “instant” oats, and they’re smaller and thinner than traditional rolled (aka “old-fashioned”) oats. This smaller size means they soften faster, and because this snack cake doesn’t bake for very long, that’s really important to achieving a nice tender texture!
However, it’s extremely important to measure the flour and oats correctly, using this method or a kitchen scale. (← That’s the one I have!) Too much of either ingredient will make your healthy snack cake turn out dry or crumbly… Especially the oats! They act like little sponges and soak up lots of moisture from the batter, so make sure you measure them carefully!
You’ll also mix plenty of spices into the flour and oats: cinnamon (this kind works exceptionally well!) and nutmeg (like this!). The nutmeg was a special secret addition to Grandma’s zucchini bread, and after trying this snack cake both with and without… I totally understand why! The nutmeg adds a deep richness, depth, and fullness to the spice flavor, so don’t skip it!
With a mere ½ tablespoon of butter (yes, that’s it!) and 2 egg whites, the majority of this snack cake’s tender texture comes from Greek yogurt. I love using Greek yogurt in my healthy baking recipes because it adds the same moisture as extra butter or oil — but for a fraction of the calories! And it also gives your snack cake a big protein boost. Win-win!
You’ll skip the refined granulated sugar and sweeten your healthy oatmeal snack cake with pure maple syrup. You want the kind that comes directly from maple trees and only has one ingredient: maple syrup. It’s usually sold in thin glass bottles or squat plastic jugs (like this!).
Of course, we can’t forget the freshly grated zucchini! Before stirring it into the batter, remember to thoroughly pat it dry with paper towels to squeeze out the extra moisture. If you don’t, that extra water gets released into this cake while it bakes, which adds too much moisture… And that means your snack cake will turn out underdone in the middle and collapse while cooling. Not good! It only takes a couple extra minutes to squeeze out that moisture, and I promise the end result is worth it!
Tip: I like to place a double-thick layer of paper towels on a cutting board, evenly spread the grated zucchini on top, and firmly press down with another double-thick layer of paper towels until that top layer is completely wet. I continue to repeat this with a fresh set of paper towels on top until I can’t soak up any more moisture. It works like a charm!
HOW TO MAKE THE BEST HEALTHY ZUCCHINI OATMEAL SNACK CAKE
Now that you’ve gathered and measured your ingredients (you did take the time to do that properly for the oats and flour, right??), let’s quickly talk about how to make the best healthy zucchini oatmeal snack cake! There are four key things we should cover, starting with…
Alternating additions. This little trick yields the best texture in cakes! It’s a shorthand way of saying add some of the flour mixture, gently fold it in, pour in some of the milk, gently stir that in, and keep switching between them until you run out of flour mixture and milk.
Alternating additions help guard against overmixing. When batter is overmixed, the cake can turn out tough, gummy, or rubbery — not good! Yet when the batter is gently and carefully brought together, your cake will have a beautifully moist and soft texture.
Use a fork. Yes… As strange as it sounds, I highly recommend a fork to make the batter! Unlike the flat surface of a spatula or wooden spoon, the open spaces between a fork’s tines allow ingredients to pass through and mix together more efficiently. That helps guard against overmixing as well!
Tip: Skip your stand mixer and hand-held mixer! Even on their lowest settings, these often overmix low fat batters, such as this one. For the best results, use a whisk where explicitly instructed, and use a fork for everything else.
Bake. This cake doesn’t stay in the oven for too long! It’s done when the center feels firm to the touch and a toothpick comes out clean or with a few crumbs attached. Because of the really moist zucchini, the crumbs might not look entirely dry, but that’s okay. Focus on no raw batter!
Cool completely. Yes, I know… It’s incredibly tempting to cut into this cake while it’s still warm. That cozy aroma gets to me too! However, a cake’s structure doesn’t fully set until the cake is completely cool. If you slice into it while it’s still warm, you’ll disrupt that process… So for the best texture, wait until your cake has reached room temperature. (But you can pop it in the fridge once the pan is cool enough to touch with your bare hands to speed up the process!)
Doesn’t that look tempting?? 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 healthy zucchini oatmeal snack cake!
Healthy Zucchini Oatmeal Snack Cake
Ingredients

Helen says...
I sub flax for a whole egg, does anything work for the whites? I know you play with substitutions sometimes for your brother and wondered if you had tried any in this recipe.
Amy says...
You know me well, Helen! 😉 In my recipes, I always use Ener-G as my egg substitute. It’s had the best results of any egg replacers that I’ve tried, including flax! For my recipes, use 1 ½ teaspoons Ener-G + 2 tablespoons warm water for each egg white (and you’ll need an additional ½ tablespoon of butter or coconut oil {or Earth Balance, if you’re vegan!} for each egg yolk, although that doesn’t apply here!). I can’t wait to hear what you think of this snack cake! 🙂
Helen says...
Thanks so much! I’ve yet to try that, just flax, applesauce, or gelatin. I’ll have to pick some up.
Amy says...
My pleasure, Helen! It’s shelf-stable and keeps for ages — one of the many reasons I love Ener-G. 😉 I’m excited to hear how your snack cake turns out!
Corie-Ann McAssey says...
My old boss used to use flax for eggs in her muffins. What is the recipe for that? It was always so gooey just like eggs but I don’t know the measurements and ingredients.
Amy says...
I’m honored you’d ask me for advice, Corie-Ann! I don’t have much experience with flax as a substitute for eggs, but Ener-G is my favorite substitute. Ener-G is a shelf-stable powder that keeps for ages. It works perfectly as an egg replacer in nearly all of my recipes, including this one! For my recipes, use 1 ½ teaspoons Ener-G + 2 tablespoons warm water for each egg white, and you’ll need an additional ½ tablespoon of butter or coconut oil {or Earth Balance, if you’re vegan!} for each egg yolk. 🙂 I can’t wait to hear what you think of this oatmeal snack cake if you try it!
Rebeka says...
Hi Amy,
What can you use to substitute the green yogurt? I love zucchini bread and have recently been trying out being dairy free.
Thanks!
Rebeka
Amy says...
I really appreciate your interest in my recipe, Rebeka! The best substitute would be non-dairy yogurt alternatives (i.e. soy- or almond-based). I love Silk’s non-dairy yogurts! 🙂 I can’t wait to hear what you think of this snack cake!
Supriya Kutty says...
Wow! this recipe looks tempting. I have never tried zucchini, but after reading your post I would love to try it. It looks so healthy that I can give it to my daughter in her lunch box as well. Keep posting such healthy recipes and tips with the readers.
Amy says...
I’d love to hear what you think if you and your daughter try this snack cake, Supriya! 🙂
Steph says...
I’ve had chocolate cake with zucchini before and would love to try this recipe. Do you think I could sub one large egg for the two egg whites? I would rather not have left over egg yolks.
Amy says...
I really appreciate your interest in my recipe, Steph! You can use 2 whole eggs, and that won’t affect the flavor or texture. 🙂 I can’t wait to hear what you think of this snack cake!
SY says...
Does the yoghurt need to be drained?
Amy says...
No, just use regular nonfat Greek yogurt straight from the tub! 🙂 I can’t wait to hear what you think of this snack cake!
Kate says...
Can you substitute bananas for maple syrup on this recipe?
Amy says...
I’m honored that you’d like to try this recipe, Kate! I don’t recommend that substitution for a couple of reasons. Mashed bananas aren’t nearly as sweet as maple syrup, so your snack cake would turn out with a really bland flavor, almost like plain sandwich bread, instead of having the sweetness level of muffins. Mashed bananas would also change the texture, and your snack cake could potentially collapse while cooling and turn out somewhat more dense and gummy. However, I do have a banana version of this recipe here, if you have overly ripe bananas that you’re just trying to use in a baking recipe! 🙂 I’d love to hear what you think if you decide to try either of my snack cake recipes!
Robyn says...
Wondering if this could be used with something other than zucchini, such as grated apples or carrots perhaps? Or could you do half zucchini/half apple? Thanks!
Dee Ann says...
This looks very good- I am wondering if you think it would freeze well? Thanks
Amy says...
Yes! Once sliced, the individual pieces of this snack cake freeze (and thaw!) really well. 🙂 I’d love to hear what you think if you try making it, Dee Ann!
