Ingredient Notes & Substitutions
- Bananas: Use very ripe bananas with brown spots. They add natural sweetness and moisture.
- Chocolate protein powder: A chocolate protein powder works best here. If your protein powder is very sweet, you can slightly reduce the maple syrup.
- Gluten-free flour blend: Use a 1:1 gluten-free baking flour blend. You can also use all-purpose flour if you do not need the muffins to be gluten-free.
- Almond flour: Almond flour adds moisture and a softer texture. Do not replace it with coconut flour because coconut flour absorbs much more liquid.
- Cacao powder: Unsweetened cocoa powder can be used if you do not have cacao powder.
- Olive oil: Use a mild olive oil. Avocado oil or melted coconut oil can also work.
- Dark chocolate chips: Use dark, semi-sweet, or mini chocolate chips depending on how sweet you want the muffins.
How to Make Double Chocolate Protein Muffins
- Preheat the oven to 350°F (175°C). Line a muffin pan with paper liners.
- In a bowl, whisk together the gluten-free flour, almond flour, chocolate protein powder, cacao powder, baking powder, baking soda, and salt.
- In a separate large bowl, mash the ripe bananas until mostly smooth.
- Add the egg, maple syrup, olive oil, and vanilla extract to the mashed bananas. Whisk until combined.

- Add the dry ingredients to the wet ingredients and mix until a thick chocolate batter forms.
- Fold in the dark chocolate chips.
- Divide the batter evenly between the muffin cups.
- Sprinkle extra chocolate chips on top, and add a tiny pinch of flaky sea salt if using.
- Bake until the muffins are risen and a toothpick inserted into the center comes out with a few moist crumbs.

- Let the muffins cool in the pan for a few minutes, then transfer to a rack.

Expert Tips
- Use very ripe bananas for the best sweetness and soft texture.
- Do not overmix the batter after adding the dry ingredients.
- Check your muffins early because protein powder can make baked goods dry if overbaked.
- Use paper liners to make the muffins easier to remove.
- Add extra chocolate chips on top for a prettier bakery-style look.
- Let the muffins cool before opening one so the crumb can set.
- If your batter looks too thick, add 1 tablespoon of milk.
- Store them chilled if your kitchen is warm.
Storage & Freezing
- Room temperature: Store in an airtight container for up to 2 days.
- Refrigerator: Store for up to 5 days. Warm slightly before serving for a softer texture.
- Freezer: Freeze cooled muffins in a freezer-safe bag or container for up to 2 months. Thaw at room temperature or warm gently in the microwave.

Variations
- Peanut butter chocolate muffins: Add 2 tablespoons peanut butter to the wet ingredients.
- Extra chocolate muffins: Add more chocolate chips on top before baking.
- Nutty muffins: Fold in 1/3 cup chopped walnuts or almonds.
