These super healthy black bean brownies are the ultimate answer when you crave something decadent and chocolaty but want to sneak in some nourishment. The beans make them fudgy and surprisingly satisfying without any hint of their actual flavor. I love making these for unsuspecting friends and seeing the shock when I reveal what is inside after they have finished eating.
I made these for my kids one afternoon when I was out of flour and the pan disappeared in under an hour. Now it is our go to treat for busy weeks and after school snacks.
Ingredients
- Black beans: Make sure to drain and rinse them thoroughly for a clean flavor. Look for cans with low sodium if possible
- Cocoa powder: Use a good unsweetened cocoa for the deepest chocolate taste. I like Dutch processed for extra richness
- Quick oats: These serve as the structural backbone. The finer the oats the smoother the finished texture
- Salt: A pinch balances sweetness and brings out the chocolate flavor
- Maple syrup or honey: Adds sweetness and a natural moist texture. Select real maple syrup for best taste
- Stevia or sugar: Optional extra lift for sweetness. Adjust to your preference or leave out for less sweet brownies
- Coconut or vegetable oil: Moistens the brownies and helps with fudgy texture. Refined coconut oil gives no coconut taste
- Pure vanilla extract: Rounds out the chocolate and adds aromatic depth
- Baking powder: Gives a slight lift for just the right chew
- Chocolate chips: Absolutely essential for gooey pockets of chocolate throughout. Choose a quality brand and do not skip
- Extra chips: Sprinkle over the top for bakery like presentation and added chocolate boost
Step-by-Step Instructions
- Preheat the Oven:
- Set your oven to 350 degrees Fahrenheit ahead of mixing your batter so it is at temperature when you are ready to bake
- Blend the Batter:
- Combine the black beans, cocoa powder quick oats salt maple syrup stevia or sugar oil vanilla extract and baking powder in a good food processor. Blend thoroughly stopping to scrape the sides as needed. You want this mixture completely smooth as this is key for disguising the beans and creating a thick fudge like base
- Add Chocolate Chips:
- Transfer the batter to a bowl or just remove the blade and stir in your chocolate chips by hand. Folding the chips in now makes sure they are evenly distributed throughout every bite
- Prepare the Pan:
- Grease an eight by eight inch baking pan thoroughly. Pour the brownie batter in and smooth the top evenly with a spatula. For extra appeal scatter a few extra chocolate chips over the surface
- Bake:
- Place the pan in the oven and bake for fifteen to eighteen minutes. The brownies are done when the top is set and the edges have begun to pull away from the sides of the pan. They may look underdone but will firm as they cool
- Cool Before Slicing:
- Let brownies cool in the pan for at least ten minutes before slicing. If they seem too soft or gooey place them in the fridge overnight and they will magically firm up for clean slices and perfect texture

My favorite part of this recipe is the moment when friends realize these are no ordinary brownies. I love that my youngest child who normally protests beans happily eats two of these and asks for more. They have become a staple comfort bake in our kitchen.
Storage Tips
After baking let the brownies cool completely before storing. They keep in an airtight container at room temperature for up to two days or in the fridge for up to five days. For longer storage cut them into squares and freeze. I pop them into lunchboxes frozen and by lunchtime they are thawed and perfectly fudgy.
Ingredient Substitutions
You can swap the quick oats for rolled oats blended in a blender or food processor until fine. To make these brownies fully plant based use maple syrup or agave and stick with coconut oil. If you are out of chocolate chips you can chop a chocolate bar into chunks but do not leave out the chocolate as it makes a huge difference.
Serving Suggestions
These brownies are amazing plain but you can level them up. Serve warm with a scoop of vanilla ice cream a drizzle of chocolate sauce or a dollop of whipped cream. Sprinkling a pinch of flakey sea salt on top is my secret move for making them taste extra fancy.

Cultural or Historical Context
Bean based desserts are not a new trend. Around the world beans have often been used to make sweets and cakes especially in Asian and South American cooking. Using black beans in brownies is a clever twist on a long tradition of finding creative ways to incorporate nutritious staples into beloved treats.
