Notes: Instant oats are also known as “quick-cooking” or “one-minute” oats. They’re smaller and thinner than old-fashioned oats. To make your own out of old-fashioned oats, add ¾ cup (75g) of old-fashioned oats to a blender or food processor, and pulse until they’re ⅛ to ¼ of their original size.
For the gluten-free flour, use the following: 1 cups (120g)
millet flour, ½ cup (60g)
tapioca flour, ½ cup (60g)
brown rice flour, and 1 ½ teaspoons
xanthan gum. Most store-bought gluten-free flour blends (like
this one!) will work as well, if measured
like this.
Whole wheat pastry flour, regular whole wheat flour, or all-purpose flour may be substituted in place of the white whole wheat flour.
Remember to measure your oats and flour correctly, using
this method or a
kitchen scale. (← That’s the one I own!) Too much of either will make your muffins turn out dry. This is especially true of the oats because they act like sponges and soak up lots of moisture from the batter.
The muffins require 2 full egg whites. The whites contain the majority of the protein in eggs, and that protein is required to ensure the muffins maintain their shape and texture while cooling. Without both egg whites, the muffins may collapse while cooling and turn out much denser.
For sweeter muffins, increase the liquid stevia by an additional ¼ or ½ teaspoon.
I do not recommend substituting for the liquid stevia, if at all possible. (It’s one of my favorite ingredients, and you’ll use it in all of
these recipes of mine, too!) I buy it online
here because that's the best price I've found. However, if you really prefer to omit the liquid stevia from the muffins, substitute 1 cup (192g) granulated sugar, brown sugar, or
coconut sugar and reduce the milk to ½ cup + 2 tablespoons (150mL). You may also substitute 1 cup (240mL) of
pure maple syrup,
honey, or
agave and reduce the milk to 2 tablespoons (30mL) instead. The baking time may vary with either of those substitutions as well.
Any milk may be substituted in place of the nonfat milk.
Do not substitute store-bought pre-shredded carrots (also called “matchstick” carrots). They’re too thick and dry, and they don’t soften properly while baking.
Do not use an electric mixer to mix up the batter. This will result in dense or tough muffins. Use a whisk where instructed, and use a fork for everything else.
