Craving brownies but want something you can actually feel good about? These fudgy sweet potato brownies are packed with protein, fiber, and serious chocolate vibes.

These Sweet Potato Protein Brownies are rich, fudgy, chocolatey, and somehow still made with simple, nourishing ingredients. They’re one of those desserts that feel totally indulgent but secretly pack in some veggies and a solid boost of plant-based protein.
If you’ve been around here a while, you know I love sneaking extra goodness into my sweets. These brownies get their soft, fudgy texture from sweet potato and a delicious protein boost from Earthchimp Chocolate Protein Powder. I’ve been using Earthchimp protein for about a year now and I love it because it’s made from real ingredients and includes gut-friendly probiotics. It’s smooth, not chalky, and makes these brownies taste like pure chocolate heaven.

How to Cook the Sweet Potato
For the best fudgy brownies, make sure your sweet potato is fully cooked and cooled before blending. It should be soft, creamy, and easy to mash so it blends smoothly into the batter.
You can cook it a few different ways:
- Bake: Pierce with a fork and bake at 400°F for 40–45 minutes, until tender.
- Microwave: Pierce with a fork and microwave for 5–7 minutes, flipping halfway through.
- Air Fryer: Pierce with a fork and cook at 380°F for 25–30 minutes, until the skin is crisp and a fork slides in easily.
Once cooked, let the sweet potato cool completely before using. You can even prep it a day ahead and store it in the fridge — using cooled sweet potato helps the brownies hold together and gives them that extra fudgy texture.
Storage
Keep leftovers in an airtight container:
- In the freezer for up to 2 months (thaw before eating)
- At room temperature for up to 2 days
- In the fridge for up to 5 days
Tips for the Best Texture
- Let the brownies cool fully before slicing. They get fudgier as they sit.
- If your sweet potato is dry, add a splash of extra soy milk while blending.
- Sprinkle extra chocolate chips on top before baking for an extra treat.

Recipe

Sweet Potato Protein Brownies
Ingredients
- ½ cup rolled oats gluten free if needed
- ⅓ cup Earthchimp chocolate plant-based protein powder
- ¼ cup cocoa powder
- ½ teaspoon baking soda
- ⅛ teaspoon salt
- 1 cooked & cooled medium sweet potato about 200g
- ¼ cup maple syrup
- ¼ cup soy milk
- 1 teaspoon vanilla extract
- ¼ cup vegan chocolate chips optional
Instructions
- Preheat your oven to 400°F (200°C) and line a 9x5-inch loaf pan with parchment paper.
- Add all ingredients except the chocolate chips to a high-speed blender or food processor: rolled oats, protein powder, cocoa powder, baking soda, salt, cooked sweet potato, maple syrup, soy milk, and vanilla extract.
- Blend until the mixture is completely smooth and thick, stopping to scrape down the sides as needed. A few bits of oats left behind is no problem.
- Spread the batter evenly into your prepared pan and smooth the top with a spatula. Top with chocolate chips, if using.
- Bake for 18 minutes. Cool completely (at least 30 minutes) before slicing. The brownies will firm up as they cool.
