Preheat oven to 350°F.
Butter or oil an 8×8 baking pan and set aside.
Put beans, coconut oil, and sugar in the bowl of your food processor. Pulse until pasty and well combined.
Add cocoa powder, salt, baking powder, and vanilla. Blend until smooth.
Add in eggs and blend briefly, just until combined. Remove the bowl from the food processor and take out the blade.
Gently stir in chocolate chips with a silicone spatula.
Pour batter into the buttered 8×8-inch pan. Top with more chocolate chips if desired.
Bake for 20-25 minutes. Brownies should begin pulling away from the sides of the pan. A toothpick may not come out clean; that’s okay, but brownies shouldn’t jiggle much in the center.
Let cool completely before serving. If you have leftovers, store them in an airtight container in the refrigerator.
