Ingredients You’ll Need

- Oat flour (or all-purpose) 3/4 cup: Provides a tender crumb and adds a bit of natural sweetness and fiber to your brownies.
- Cocoa powder, unsweetened 1/2 cup: Brings that deep, rich chocolate flavor without adding extra fat or sugar.
- Baking powder 1/2 tsp: Ensures your brownies rise just enough, giving them a soft and slightly airy texture.
- Salt 1/4 tsp: Enhances all the other flavors and balances the sweetness beautifully.
- Greek yogurt 1 cup: Adds moisture, protein, and a slight tang that elevates the overall taste.
- Almond milk 1/2 cup: Keeps the batter smooth and light while complementing the yogurt without overpowering flavor.
- Sweetener of choice (Monk fruit preferred) 1/2 cup: Adds just the right amount of sweetness without the calorie overload.
- Dark chocolate chips 3.5 ounces: Melted into the batter, they add a luscious chocolate richness and extra flair.
How to Make Low-Calorie Protein Brownies
Step 1: Prepare Your Oven and Pan
Start by preheating your oven to 350°F (175°C). Line an 8×8-inch baking dish with parchment paper and lightly grease it to ensure your brownies release easily after baking. This simple prep step sets the stage for perfectly baked brownies that don’t stick or crumble.
Step 2: Mix the Dry Ingredients
Next, whisk together the oat flour, unsweetened cocoa powder, baking powder, and salt until everything is evenly combined with no clumps. This blend is the chocolatey base that will give your brownies their rich flavor and satisfying texture.
Step 3: Combine the Wet Ingredients
In a separate bowl, add your Greek yogurt, almond milk, and sweetener of choice. Stir gently to combine—this creates the creamy, moist base for your brownie batter, ensuring the protein stays intact and the texture stays soft.
Step 4: Bring the Batter Together
Pour the wet ingredients into the dry mixture and gently stir until everything is just combined. Your batter should be thick but still pourable; if it feels too dense, add a splash of almond milk to loosen it slightly. This ensures even baking and a tender crumb.
Step 5: Melt the Chocolate Chips
Melt your dark chocolate chips by heating them in short 20-second bursts in the microwave, stirring frequently until smooth. If the texture feels too thick, stir in a small amount of coconut oil to achieve that glossy, silky consistency you’re looking for.
Step 6: Incorporate Melted Chocolate
Fold the melted chocolate into the batter until it becomes glossy and fully combined. This step infuses the brownies with intense chocolate flavor and creates a luscious, fudgy texture that makes these Low-Calorie Protein Brownies absolutely irresistible.
Step 7: Bake Your Brownies
Pour the batter evenly into your prepared baking dish, spreading it with a spatula. For an extra touch, sprinkle a few more chocolate chips on top. Bake for 30 to 35 minutes—edges should be set, and a toothpick inserted into the center should come out with moist crumbs but not wet batter.
Step 8: Cool and Slice
Allow the brownies to cool in the pan for at least 20 minutes, then lift them out using the parchment paper and let them cool completely before slicing. This cooling step helps the brownies firm up, so they cut cleanly and hold their shape beautifully.
How to Serve Low-Calorie Protein Brownies
Garnishes
Adding a garnish like a light dusting of cocoa powder or a sprinkle of crushed nuts can elevate the brownies visually and texturally. Fresh berries or a drizzle of a low-sugar chocolate sauce are also delightful for added flavor and color.
Side Dishes
Serve these brownies alongside a dollop of vanilla Greek yogurt or a small scoop of low-fat ice cream for an indulgent yet balanced dessert experience. A hot cup of coffee or herbal tea pairs perfectly to complement the rich chocolate notes.
Creative Ways to Present
For an eye-catching presentation, cut the brownies into bite-sized squares and serve on a platter with toothpicks for easy snacking at parties. Alternatively, layer brownie pieces with Greek yogurt and fresh fruits in a parfait glass for a creatively indulgent treat.
Make Ahead and Storage
Storing Leftovers
Leftover Low-Calorie Protein Brownies store wonderfully in an airtight container at room temperature for up to 3 days. For longer freshness, move them to the refrigerator, where they will keep moist and delicious for up to a week.
Freezing
You can freeze brownies by wrapping individual pieces tightly in plastic wrap and placing them in a freezer-safe container or bag. This method preserves their texture and flavor for up to 3 months, making them perfect for future cravings.
Reheating
To enjoy frozen or refrigerated brownies warm, simply microwave for 15 to 20 seconds or pop them in a preheated oven at 300°F for 5 to 7 minutes. Warmed brownies bring back that freshly baked softness and melty chocolate goodness every time.
FAQs
Can I substitute the oat flour with another type of flour?
Absolutely! While oat flour adds a nice texture and fiber, you can use all-purpose flour or even almond flour if you prefer. Just keep in mind the texture might shift slightly depending on the choice.
Is it possible to make these brownies vegan?
To make these Low-Calorie Protein Brownies vegan, swap out Greek yogurt for a non-dairy yogurt alternative and use plant-based milk as specified. Make sure your sweetener and chocolate chips are also vegan friendly.
How many brownies does this recipe yield?
This recipe bakes up into about 9 standard-sized brownies, perfect for sharing or savoring throughout the week as a protein-packed snack.
Can I use regular sugar instead of monk fruit sweetener?
Yes, regular sugar or another sweetener like maple syrup can be used, but keep in mind it may increase the calorie count slightly. Adjust to your preferred sweetness level accordingly.
What’s the best way to keep these brownies moist?
The Greek yogurt in the recipe does a fantastic job of keeping the brownies moist, but ensuring you don’t overbake them is key. Remove from the oven as soon as a toothpick comes out with moist crumbs for the best results.
