This quick single-serving protein brownie is perfect when you need a healthy treat fast. It satisfies chocolate cravings while packing a solid protein punch which makes it a great snack or post-workout boost. The recipe whips up in under five minutes and cooks in the microwave, so you skip any complicated prep or clean-up.
I first made this after a late gym session craving chocolate but didn’t want to undo my efforts. It quickly became my go-to when I needed something sweet yet nourishing without fuss.
Ingredients
- Egg: for binding and a dose of natural protein and fat
- Plain Greek yogurt: adds creaminess, moisture, and extra protein — pick a thick variety for best texture
- Sweetener: like honey or maple syrup to balance the cocoa bitterness — adjust to taste and quality matters for clean flavor
- Cocoa powder: brings rich chocolate flavor — choose unsweetened and fresh for vibrant taste
- Chocolate protein powder: boosts protein content and enhances chocolate intensity — opt for one you enjoy the flavor of as it shapes the final taste
- Chocolate chips: add fun bursts of melted chocolate — use dark or semi-sweet, maybe even mini chips for even distribution
Instructions
- Build The Batter:
- Whisk the egg and plain Greek yogurt together in a small bowl until silky smooth. Gradually mix in your chosen sweetener and cocoa powder, stirring carefully to eliminate lumps. Then fold in the chocolate protein powder until fully incorporated. This blending creates a thick, fudgy base for your brownie.
- Add The Chips:
- Gently stir the chocolate chips into the batter. This step is key because it ensures the chips don’t melt into the batter but stay as pockets of gooey chocolate in each bite.
- Prepare To Cook:
- Lightly grease a microwave-safe mug or ramekin with a bit of butter or oil. This prevents sticking and helps the brownie come out clean and intact.
- Cook The Brownie:
- Pour the batter into your greased dish and microwave on high for 90 to 120 seconds depending on microwave strength and desired fudginess. Start checking at 60 seconds and then every 10 seconds to avoid overcooking. The top should look set but the center will still be slightly soft.
- Serve It Up:
- Top with extra Greek yogurt, nut butter, fresh berries, sliced banana, or more chocolate chips. These toppings add texture, flavor layers, and extra nutrition that elevate this simple dessert.

What I love most is the creamy texture the Greek yogurt brings which balances the cocoa’s richness beautifully. This brownie has become a comforting ritual during stressful workdays, reminding me that healthy treats can feel indulgent.
Storage Tips
Because this brownie is best fresh and slightly warm it’s ideal to eat immediately but if you have leftovers refrigerate in an airtight container for up to two days. Reheat gently in the microwave to retain that soft texture. Avoid freezing as it can alter the fudginess and cause dryness.
Ingredient Swaps
If you do not have Greek yogurt, use an equal amount of regular yogurt or mascarpone but note it may be less thick. Use pea or rice protein powder for a dairy-free option. Sweeten with mashed banana if you prefer natural sugar from fruit. To make it vegan, substitute the egg with flax or chia egg and choose plant-based protein powder and yogurt.
Serving Ideas
Enjoy on its own as a quick snack or dress it up for dessert. Serve warm with a scoop of vanilla ice cream or drizzle melted peanut butter on top. Pair it with fresh fruit or a cup of coffee for a satisfying afternoon pick-me-up.

This protein brownie is a fast, satisfying treat that balances indulgence with nutrition perfectly.
