FAQs

How do I store high-fiber brownies?

Store your high-fiber brownies in an airtight container at room temperature for up to 4 days, or in the fridge for up to 7 days. For longer storage, wrap them individually and freeze for up to 2–3 months.

How do they taste?

If I didn’t tell you there were beans in here, you’d never guess. The texture is soft and rich—almost like a cross between a brownie and a chocolate cake. They’re not overly sweet, which I personally love, and they feel satisfying in a way regular brownies sometimes don’t.

Equipment

Ingredients

  • 1 can 15 oz (425g) black beans
  • 3 large eggs
  • 3/4 cup (150g) granulated sugar
  • 2 (!!) teaspoons vanilla extract
  • 1/2 cup (120ml) canola oil or vegetable oil
  • 1/2 cup (70g) cocoa powder
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon instant coffee optional
  • A pinch of salt
  • Cooking spray or oil for greasing the pan
  • Powdered sugar for garnish optional

Instructions

  • Preheat the oven to 320°F/160°C.
  • Line a baking pan with parchment paper and grease it with oil.
  • Drain the black beans and rinse thoroughly in a colander under running water for 2 minutes.
  • Put the beans in the food processor with the eggs and sugar and mix nonstop until a completely smooth mixture is formed (about 2 minutes).
  • Add vanilla, oil, cocoa powder, baking powder, baking soda, coffee *optional*, and salt.
  • Process until everything is mixed well.
  • Pour the batter into the baking pan.
  • Bake for 30-35 minutes until the cake is puffed, burst at the top, and slightly gooey in the center. You can insert a cake tester/skewer into the center of the cake; if it comes out clean with a few small crumbs, the cake is ready.
  • Let it cool completely before cutting into squares.
  • *Optional* dust with powdered sugar.

Notes

  • Rinse and drain the beans well: It’s important to rinse and drain them well to remove any excess starch or off flavors. This will help ensure that the cake has a smooth and even texture.
  • Puree the beans thoroughly: This will help create a smooth and uniform texture in the cake.
  • Don’t over-bake: Because cakes made with beans tend to be moister than traditional cakes, they can take longer to bake. However, it’s important not to over-bake the cake as it can become dry and crumbly. Keep a close eye on the cake towards the end of the baking time. Insert a toothpick or cake tester into the center of the cake. If it comes out clean or with just a few moist crumbs attached, the cake is done.
