This is an epic of a basic muffin recipe that you can then add flavor to in all sorts of ways—from fruit to veggies to chocolate chips. The batter is packed with protein too, so the muffins are great for breakfast or snack. (The allergy-friendly substitutions are listed in the Notes section at the bottom.)
Preheat the oven to 375 degrees F. Grease a 12-cup standard muffin pan with nonstick spray.
In a medium bowl, stir together the flours, baking powder, baking soda, and salt.
In another bowl, stir together the yogurt, maple syrup, eggs, butter, and vanilla.
Gently stir the yogurt mixture into the flour mixture.
Add your desired add-in. (You can also add 1 tablespoon of any add-in to each muffin cup, using 1/4 cup batter, to make a batch with a few different flavors. Or you can bake them plain). Stir gently to combine.
Divide batter among the prepared muffin tin, using about 1/4 cup batter in each cup.
Bake for 16-18 minutes, or until the edges are lightly golden brown and a cake tester inserted into the center comes out cleanly. Remove from oven, then transfer muffins to a wire rack to cool fully.
Once cooled, store in an airtight container for up to 3 days at room temperature. Store in the fridge in an airtight container for up to 5 days. Warm slightly to serve from the fridge (they firm up a bit when they're cold so warming slightly returns them to their softer texture).
You can also freeze the muffins in a freezer bag with as much air removed as possible for up to 3 months. Thaw at room temperature or in 15 second increments in the microwave.
Use one add-in per batch of muffin, or use 1 tablespoon of each per muffin to make a mixed batch.
I like using whole milk Greek yogurt in this recipe.
Dairy-free: Use a nondairy Greek style yogurt like the plant-based options from Siggis and a neutral oil like canola in place of the butter.
Gluten-free: Substitute cup-for-cup gluten-free flour in place of the wheat flours.
Egg-free: Omit the eggs. Reduce the yogurt to 3/4 cup. Add 1/4 cup milk. Proceed with the recipe.
