Why This Recipe Works

These Protein Brownies with Collagen are a perfect blend of flavor and nutrition. Using almond flour gives them a moist texture, while the chocolate protein powder and collagen provide a protein punch and additional health benefits. Collagen is known for supporting skin, hair, nails, and joint health, making these brownies a smart choice for anyone looking to enhance their wellness routine. Furthermore, the use of erythritol as a sweetener keeps the sugar content low without sacrificing taste.
Ingredients at a Glance

- 1 cup almond flour – for a gluten-free base with great texture.
- 1 cup chocolate protein powder or 1 cup protein powder + 1 cup collagen powder – to boost the protein content.
- 1 cup erythritol sweetener or granulated sugar – for sweetness without the calories.
- 1/3 cup unsweetened cocoa powder – adds rich chocolate flavor.
- 1 teaspoon baking powder – for a little lift.
- 1 teaspoon salt – enhances the flavors.
- 10 tablespoons melted butter or melted coconut oil – for that fudgy texture.
- 3 large eggs – binds the ingredients together.
- 1 tablespoon vanilla extract – adds warmth and depth of flavor.
- 1 cup keto chocolate chips or regular chocolate chips – for a gooey, chocolatey finish.
Prep & Cook Tools

- Mixing bowl – for combining your dry and wet ingredients.
- Whisk – to mix the ingredients smoothly.
- 9×9-inch baking pan – the perfect size for these brownies.
- Parchment paper – to line the baking pan for easy removal.
- Measuring cups and spoons – for accurate ingredient measurements.
- Spatula – for spreading the batter evenly in the pan.
Protein Brownies with Collagen — Do This Next
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your brownies cook evenly and achieve that perfect fudgy texture.
Step 2: Prepare the Baking Pan
Line a 9×9-inch baking pan with parchment paper, allowing some overhang for easy removal later. This step is crucial for keeping your brownies intact when slicing.
Step 3: Combine Dry Ingredients
In a large mixing bowl, whisk together the almond flour, chocolate protein powder (or protein and collagen), erythritol sweetener, cocoa powder, baking powder, and salt until well combined.
Step 4: Mix Wet Ingredients
In another bowl, whisk the melted butter (or coconut oil), eggs, and vanilla extract until smooth and well blended.
Step 5: Combine Wet and Dry Mixtures
Pour the wet ingredients into the dry mixture and stir with a spatula until just combined. Be careful not to overmix, as this can lead to denser brownies.
Step 6: Fold in Chocolate Chips
Gently fold in the keto chocolate chips or regular chocolate chips, ensuring they are evenly distributed throughout the batter.
Step 7: Bake
Spread the brownie batter evenly in the prepared baking pan. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
Step 8: Cool and Slice
Allow the brownies to cool in the pan for about 10 minutes before using the parchment overhang to lift them out. Let them cool completely on a wire rack before slicing into squares.
Ingredient Swaps & Substitutions
- Nut-free option: Replace almond flour with oat flour or sunflower seed flour.
- Sweetener alternatives: Use monk fruit sweetener or honey (if not strict keto).
- Butter substitute: Use avocado oil or applesauce for a lighter option.
- Protein powder: Vanilla protein powder can be used for a different flavor profile.
Troubles You Can Avoid
- Overmixing the batter can lead to dense brownies. Mix until just combined.
- Using too much cocoa powder can make brownies overly dry. Stick to the recommended amount.
- Not letting the brownies cool completely before slicing can result in crumbling. Patience is key!
Freezer-Friendly Notes
These Protein Brownies with Collagen are perfect for meal prep and can be frozen for later enjoyment. Once cooled, slice the brownies and place them in an airtight container or wrap them individually in plastic wrap. Store them in the freezer for up to three months. When you’re ready to indulge, simply thaw at room temperature or warm them in the microwave for a few seconds.
