Fluffy and perfectly moist, these little muffins have protein and calcium—plus bursts of delicious blueberries. (They're like Little Bites, but with more nutrients and for less $$.) See Notes for allergy variations.
Preheat the oven to 375 degrees F. Grease a 24-cup mini muffin pan with nonstick spray.
In a medium bowl, stir together the flour, sugar, baking powder, baking soda, and salt.
In another bowl, stir together the yogurt, eggs, butter, and vanilla.
Gently stir the yogurt mixture into the flour mixture.
Divide batter among the prepared muffin tin, filling about to the edge. (You'll use about 1 1/2 tablespoons in each mini muffin cup.) Add a few blueberries to the top of each and press down slightly.
Bake for 12-14 minutes, or until the edges are lightly golden brown and a cake tester inserted into the center comes out cleanly.
(To make these as full-size muffins, use a 12-cup muffin pan and bake for 16-18 minutes.)
Remove from oven, and let cool in the pan for 2 minutes. Run a paring knife around the edges to loosen, if needed, then carefully transfer muffins to a wire rack to cool fully.
Notes
Once cooled, store muffins 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 as they will firm up when cold.
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.
You can stir the berries into the batter, though they have a tendency to sink to the bottom of the muffins (even if tossed in flour first). The way I have it in the instructions is the best way I know to wind up with blueberries throughout the muffins.
You can use fresh or frozen blueberries, full size or wild blueberries (which are smaller). If you use frozen berries and they start to thaw, the batter may look a little tie-dyed.
Dairy-free: Use a nondairy Greek style yogurt like the plant-based options from Siggi's and a neutral oil like canola in place of the butter. Or use nondairy milk the batter will be a lot runnier but it will still work.
Egg-free: Omit the eggs. Add 1/3 cup milk and use 3/4 teaspoon baking soda.
Gluten-free: Use cup for cup gluten-free all-purpose flour.
Whole-wheat: Sub in whole-wheat flour for the all-purpose in the same amount. Check for doneness on the lower end of the baking time.
Lower-sugar: Reduce the sugar to 1/4 cup if desired.
Add lemon zest or cinnamon for additional flavor. They're great plain, but those are nice adds!
