If you’re looking for muffins that are always in season, you can’t go wrong with these High-Protein Banana Oat Muffins! They are the perfect grab-and-go, portable snack (or breakfast) made with whole-grain flour, oat flour, and ripened bananas. For that extra boost of protein we used plant-based protein powder, hemp seeds, and soy-based milk and yogurt (although any plant-based variety will do). One snack-size serving (2 muffins) supplies a generous 14 grams of protein and 4 grams of fiber.

Recipe FAQs

Q: Can I use a different type of plant-based milk or yogurt?

A: Absolutely! Use whatever type you like best or that is most convenient. We use soy milk in many of our recipes for the extra protein. However, pea milk is a great alternative that is also high in protein. Other milk varieties you can use are almond, oat, or coconut.

Q: What type of protein powder works best?

A: For this recipe, vanilla flavored protein powder works best. Use whatever brand protein you have on hand. A few brands we trust that are favorites right now are:

• Nufyx Heavenly Protein Powder
• Complement Organic Protein
• Vedge Plant Protein

Q: Can I make these gluten-free?

A: To make these gluten-free simply replace the white whole wheat flour with a 1:1 gluten-free baking flour. Please note that the texture may be slightly different, but they should still turn out well.

Q: Can I freeze these muffins?

A: Of course! Allow them to cool completely before freezing. Store them in a freezer-safe bag for up to three months. To thaw, place them in the refrigerator or defrost them briefly in the microwave.

Q: What is the purpose of letting the batter rest before baking?

A: Allowing the batter to rest will help to hydrate the oat flour and protein powder. This helps create a softer, more tender muffin texture.

Q: Can I add nuts or chocolate chips to the batter?

A: Yes! After combining the wet and dry ingredients, fold in about ½ cup chopped nuts or dairy-free chocolate chips.

How to Make High-Protein Banana Oat Muffins

What You’ll Need

Dry Ingredients:

• Rolled oats (for the oat flour)
• White Whole Wheat Flour
• Vanilla plant-based protein powder
• Hemp seeds
• Baking powder
• Baking soda
• Salt
• Cinnamon

Wet Ingredients:

• Ripe bananas
• Unsweetened soy milk
• Plain or vanilla soy yogurt
• Maple syrup
• Vanilla extract
• Ground flaxseed (for flax egg)
• Water

How to Make This Recipe

1. Preheat the oven. Preheat the oven to 375°F (190°C). Line or lightly grease a 12-cup muffin pan.

2. Make the flax egg. In a small bowl, stir together 1 tablespoon of ground flaxseed with 2½ tablespoons of water. Set aside to thicken.

3. Make the oat flour. Add the oats to a blender or food processor and pulse until they have a powdery, flour-like texture

4. Combine the dry ingredients. In a large mixing bowl, whisk together the oat flour, white whole wheat flour, protein powder, hemp seeds, baking powder, baking soda, salt, and cinnamon.

5. Mix the wet ingredients. In a separate bowl, combine the mashed bananas, soy milk, soy yogurt, maple syrup, vanilla extract, and flax egg.

6. Make the batter. Pour the wet ingredients into the dry ingredients and stir gently until just combined. Let the batter rest for 10 minutes to allow the oats and protein powder to hydrate.

7. Fill the muffin pan. Divide the batter evenly between the 12 muffin cups. If you’d like, sprinkle a few oats on top before baking.

8. Bake the muffins. Bake at 375°F (190°C) for 6 minutes. Reduce the oven temperature to 350°F (176°C) and bake for another 11–12 minutes, or until a toothpick inserted into the center comes out clean.

9. Cool the muffins. Let the muffins cool in the pan for 5 minutes, then transfer them to a cooling rack.

Notes & Storage

Storage: Store these banana oat muffins at room temperature in an airtight container for 3-4 days. These freeze well for up to 3 months. Keep the cooled muffins in a freezer-safe bag and thaw them in the refrigerator or microwave.

Notes:

• Milk and yogurt options: We use soy-based milk and yogurt for the extra protein, but feel free to use any type you like best. We enjoy almond, oat, pea, and coconut-based varieties.
• Banana ripeness: For the best flavor, we use very ripe bananas that have plenty of brown speckles.
• Mixing the batter: For the best result and fluffier muffins, mix the batter just until the flour disappears. Overmixing can cause them to be too dense.
• Rest period: Try not to skip the 10-minute rest period. This allows the flour and protein powder to fully hydrate, resulting in a more tender texture.
• Gluten-free: Make these gluten-free by replacing the whole wheat flour with 1:1 gluten-free baking flour. Please note that the texture may be slightly different, but they should still turn out well.
• Adjust sweetness: For sweeter muffins, double the maple syrup from 2 tbsp to 4 tbsp (¼ cup). You can also use stevia in place of maple syrup if you’d like. Check the package to determine the right measurement.
