Why This Recipe Works (Quick Science)
Greek yogurt adds moisture while giving the muffins extra protein.
Protein powder helps increase the protein, but using too much can make muffins dry. Mixing it with oat flour keeps the texture soft.
Baking powder and baking soda work together to make the muffins rise well.
Fresh diced apples release moisture while baking, making every muffin tender.
Pro Tips
- Dice the apples into small pieces so they bake evenly.
- Mix only until you no longer see dry flour.
- Let the batter rest for 5 minutes before baking.
- Use room-temperature eggs and yogurt for smoother batter.
- Cool the muffins before storing to keep them from getting soggy.
Substitutions and Variations
- Swap oat flour with whole wheat flour.
- Use honey instead of maple syrup.
- Add chopped walnuts or pecans.
- Stir in raisins.
- Add a pinch of nutmeg.
- Use plain protein powder if you prefer less sweetness.
Make Ahead Tips
- Mix the dry ingredients one day ahead.
- Dice the apples just before mixing.
- Bake the muffins and freeze for up to 3 months.
Recipe
Step 1: Prepare the Oven and Pan
Heat the oven to 350°F (175°C). Line a 12-cup muffin pan with paper liners.
Step 2: Mix the Dry Ingredients
In a large bowl, whisk together 2 cups oat flour, 1 cup vanilla protein powder, 2 teaspoons baking powder, 1 teaspoon ground cinnamon, ½ teaspoon baking soda, and ¼ teaspoon salt until evenly mixed.
Step 3: Mix the Wet Ingredients
In another bowl, whisk together 2 large eggs, ¾ cup plain Greek yogurt, ¼ cup maple syrup, 2 tablespoons melted butter, and 1 teaspoon vanilla extract until smooth.
Step 4: Make the Batter
Pour the wet mixture into the dry ingredients. Add 2 cups diced peeled apples. Fold gently with a rubber spatula until everything is just combined.
Step 5: Fill the Muffin Pan
Divide the batter evenly between all 12 muffin liners, filling each about three-quarters full.
Step 6: Bake
Bake at 350°F (175°C) for 20 to 22 minutes, or until a toothpick inserted into the center comes out clean.
Step 7: Cool and Serve
Let the muffins cool in the pan for 5 minutes, then transfer them to a cooling rack before serving.
