Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
1 cup oat flour (120 g)
1/2 cup chocolate protein powder (50 g)
1/3 cup unsweetened cocoa powder (35 g)
1 teaspoon baking powder
1/4 teaspoon salt
1/2 cup natural almond butter (120 g)
1/3 cup pure maple syrup (80 ml)
1/4 cup honey (60 ml)
2 large eggs
1/3 cup unsweetened almond milk (80 ml)
1 teaspoon vanilla extract
1/2 cup dark chocolate chips (90 g)
Directions
Preheat your oven to 175°C (350°F). Line an 8×8-inch (20×20 cm) baking pan with parchment paper and lightly grease it.
In a large mixing bowl, whisk together the oat flour, chocolate protein powder, cocoa powder, baking powder, and salt until fully combined.
In a separate bowl, mix the almond butter, maple syrup, honey, eggs, almond milk, and vanilla extract until smooth and creamy.
Gradually add the wet ingredients to the dry ingredients, stirring until a thick, smooth batter forms.
Fold in the chocolate chips, reserving a small handful to sprinkle on top.
Pour the batter into the prepared pan and spread evenly. Sprinkle the remaining chocolate chips over the top.
Bake for 18–22 minutes, or until the center is just set and a toothpick inserted comes out with a few moist crumbs.
Allow the brownies to cool completely in the pan before slicing for the best fudgy texture.
Servings and timing
Servings: 9 brownies
Preparation time: 10 minutes
Baking time: 18–22 minutes
Total time: Approximately 30–35 minutes
Variations
Peanut butter swirl: Swirl 2 tablespoons of natural peanut butter into the batter before baking.
Extra fudgy: Replace 2 tablespoons of oat flour with 2 tablespoons of melted dark chocolate.
Dairy-free option: Use dairy-free chocolate chips and plant-based protein powder.
Lower sugar option: Replace honey with additional maple syrup or a sugar-free syrup alternative.
Nut-free version: Substitute almond butter with sunflower seed butter.
Storage/Reheating
Store the brownies in an airtight container at room temperature for up to 3 days.
For longer storage, refrigerate them for up to 7 days. Allow them to come to room temperature before serving for the best texture.
To freeze, wrap individual brownies tightly in plastic wrap and store in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator or at room temperature for a few hours.
To reheat, microwave a brownie for 10–15 seconds to restore its soft, fudgy texture.
FAQs
Can I use whey protein instead of plant-based protein?
Yes, whey protein works well in this recipe. The texture may be slightly softer, so monitor baking time closely.
Can I replace oat flour with all-purpose flour?
Yes, you can substitute with 1 cup (125 g) all-purpose flour, but the brownies will be less dense and slightly less hearty.
Why are my brownies dry?
Overbaking is the most common cause. Remove them when the center is just set and still slightly soft.
Can I make these brownies without eggs?
Yes, you can substitute each egg with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water). Let it sit for 5 minutes before using.
How much protein is in each brownie?
The exact protein content depends on the protein powder used, but each brownie typically contains around 8–12 grams of protein.
Can I reduce the sweetness?
Yes, you can reduce the honey slightly or use a less sweet protein powder to adjust the overall sweetness.
Do I need to sift the dry ingredients?
Sifting is not required, but it helps remove lumps from cocoa and protein powder for a smoother batter.
Can I double the recipe?
Yes, double the ingredients and bake in a 9×13-inch (23×33 cm) pan. Increase baking time by 5–8 minutes as needed.
What type of almond butter works best?
Natural, unsweetened almond butter with a smooth consistency works best for even mixing.
How do I know when the brownies are done?
The edges should be set, and the center should look slightly soft but not wet. A toothpick should come out with moist crumbs, not raw batter.
