Popular for a Reason
These muffins strike the perfect balance between indulgent banana flavor and clean, protein-forward ingredients. They are gluten-free, low in sugar, and easy to customize with mix-ins like walnuts or sugar-free chocolate chips. Best of all, the batter comes together in one bowl, making cleanup as easy as the bake.
Ingredients
- 3 ripe bananas, mashed (about 1 1/4 cups)
- 3 large eggs
- 1/3 cup melted butter or coconut oil
- 1 teaspoon vanilla extract
- 1 cup vanilla protein powder (whey or plant-based)
- 1 cup almond flour
- 1/3 cup granulated erythritol or monk fruit sweetener
- 1 1/2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1 teaspoon ground cinnamon
- 1/4 teaspoon salt
- Optional: 1/2 cup chopped walnuts or sugar-free chocolate chips
Instructions
- Preheat your oven to 350° F (177° C). Lightly grease your Standard Muffin Pan or Mini Muffin Pan with butter, coconut oil, or a light coat of nonstick spray.
- In a large mixing bowl, mash the ripe bananas until smooth. Whisk in the eggs, melted butter, and vanilla extract until fully combined.
- Add the protein powder, almond flour, sweetener, baking powder, baking soda, cinnamon, and salt directly to the wet ingredients. Stir until just combined; do not overmix.
- If using, gently fold in the chopped walnuts or sugar-free chocolate chips.
- Divide the batter evenly among the muffin cups. For the Standard Muffin Pan, fill each cup about 3/4 full. For the Mini Muffin Pan, fill each cup about 2/3 full to allow room for rising.
- Bake standard muffins for 18 to 22 minutes, or bake mini muffins for 10 to 13 minutes, until a toothpick inserted into the center comes out clean.
- Remove the pan from the oven and let the muffins cool in the pan for 5 minutes. Then transfer them to a wire rack to cool completely.
Standard vs. Mini: Choosing the Right Pan
Our heavy gauge, anodized aluminum muffin pans are designed to distribute heat evenly, which is especially important with dense, protein-rich batters like this one. The Standard Muffin Pan is ideal for grab-and-go breakfasts or hearty snacks, while the Mini Muffin Pan is perfect for portion control, kids’ snacks, or serving a crowd at brunch. Both pans’ anodized finish means quicker release and easier cleanup, so you can spend less time scrubbing and more time enjoying your muffins.
Tips for the Best Low-Carb Banana Protein Muffins
- Use very ripe, spotty bananas for the best natural sweetness and moisture.
- Do not overmix the batter once the dry ingredients are added; overmixing can make the muffins dense.
- Let the muffins cool fully before storing to prevent condensation and sogginess.
- For extra protein, stir in a scoop of collagen peptides along with the protein powder.
Storage and Reheating
Store cooled muffins in an airtight container in the refrigerator for up to 5 days, or freeze for up to 3 months. To reheat, microwave a standard muffin for about 20 seconds or a mini muffin for about 10 seconds, or warm in a 300° F (149° C) oven for 5 minutes.
