This copycat recipe recreates the dense, fudgy texture and sweet-salty flavor of a Quest Chocolate Brownie Bar using everyday ingredients. It delivers a high-protein, low-sugar treat that satisfies chocolate cravings without the ultra-processed feel of the original. The key is using a combination of whey protein and almond flour to mimic that signature chewy bite, while sugar-free chocolate chips provide the gooey pockets.
Ingredients
- 1 cup (120 g) almond flour
- 1/2 cup (60 g) chocolate or vanilla whey protein powder (see Tips)
- 1/4 cup (25 g) unsweetened cocoa powder
- 1/2 cup (100 g) granulated erythritol or monk fruit sweetener
- 1/4 tsp salt
- 1/2 tsp baking powder
- 2 large eggs (about 100 g), at room temperature
- 1/4 cup (60 ml) unsweetened almond milk (or any milk)
- 1/4 cup (60 ml) melted coconut oil or unsalted butter
- 1 tsp vanilla extract
- 1/2 cup (90 g) sugar-free chocolate chips (e.g., Lily’s)
Instructions
- Preheat the oven to 350°F (175°C). Line an 8×8-inch (20×20 cm) baking pan with parchment paper, leaving overhang on two sides for easy lifting.
- In a medium bowl, whisk together the almond flour, protein powder, cocoa powder, sweetener, salt, and baking powder until no lumps remain.
- In a separate bowl, beat the eggs. Add the almond milk, melted coconut oil, and vanilla extract, and whisk until combined.
- Pour the wet ingredients into the dry ingredients and stir with a spatula until a thick batter forms. Fold in the chocolate chips, reserving a few to sprinkle on top.
- Transfer the batter to the prepared pan and spread it evenly. Sprinkle the reserved chocolate chips over the top.
- Bake for 18–22 minutes, until the edges are set and the center is just firm to the touch. A toothpick inserted in the center should come out with a few moist crumbs, not wet batter.
- Let the brownies cool completely in the pan on a wire rack, about 1 hour. This step is crucial for achieving the dense, fudgy texture and clean slices.
- Once cool, lift the brownies out using the parchment paper and cut into 8 bars.
Tips
- Protein powder matters: Use a whey-based protein powder (not plant-based) for the best texture. Whey absorbs moisture similarly to the original Quest bars. If using plant-based protein, add 1–2 tablespoons (15–30 ml) extra almond milk, as they tend to be drier.
- Sweetener choices: Erythritol or monk fruit sweetener works best because they don’t caramelize or add moisture. If using liquid sweetener, reduce the almond milk by 2 tablespoons (30 ml) to compensate.
- Don’t overbake: The brownies will look underdone when they come out, but they set as they cool. Overbaking makes them dry and crumbly.
- Cutting cleanly: For clean edges, chill the brownies in the refrigerator for 30 minutes before cutting. Use a sharp knife and wipe it between cuts.
Serving Suggestions
Enjoy these brownies as a post-workout snack, a lunchbox treat, or a dessert with a dollop of whipped cream or a scoop of sugar-free vanilla ice cream. They also pair well with a glass of cold milk or a cup of coffee.
Variations
- Peanut Butter Swirl: Drop 2 tablespoons (30 g) of peanut butter over the batter before baking and swirl with a knife.
- Mint Chocolate: Add 1/2 teaspoon peppermint extract and use mint-flavored sugar-free chocolate chips.
- Double Chocolate: Replace 2 tablespoons (16 g) of almond flour with 2 tablespoons (16 g) of cocoa powder for a more intense chocolate flavor.
- Nutty Crunch: Fold in 1/4 cup (30 g) of chopped walnuts or pecans for extra texture.
Storage and Reheating
Store the brownies in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to 5 days. For longer storage, wrap each bar individually in plastic wrap and freeze for up to 3 months. To reheat, microwave a single bar for 10–15 seconds until just warm and fudgy.
Frequently Asked Questions
Can I use a different protein powder? Yes, but the texture may vary. Casein or a whey/casein blend will yield a chewier texture closer to the original. Plant-based protein powders tend to make the brownies more cake-like; adjust the liquid as mentioned above.
Why are my brownies too dry? Overbaking is the most common cause. Check the brownies at 18 minutes and remember they continue to set as they cool. Also, ensure you measure the almond flour correctly—spoon it into the cup and level it off, don’t pack it.
Can I make these without eggs? Yes, you can use a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water, let sit for 5 minutes). The texture will be slightly less dense, but still delicious.
How many net carbs are in one bar? The exact count depends on your protein powder and sweetener. Using typical sugar-free ingredients, each bar has about 3–4 grams of net carbs. Check your specific labels for accuracy.
Can I double the recipe? Absolutely. Double all ingredients and bake in a 9×13-inch (23×33 cm) pan for 25–30 minutes. The bars will be slightly thinner, so adjust the baking time accordingly.
Why do my brownies stick to the paper? If you use parchment paper, they shouldn’t stick. If they do, it’s likely because the paper wasn’t lined properly or the brownies were cut before they were completely cool. Use good-quality parchment and wait until fully cooled.
