Flourless Egg-Free Black Bean Brownies
Flourless Egg-Free Black Bean Brownies
Yield: 16 squares
Equipment: food processor, 8-inch square metal pan, parchment
Time and setting: 350°F; 24–30 minutes
Ingredients
- 1 can (15 ounces) black beans, drained and rinsed
- 1/2 cup smooth peanut butter
- 1/2 cup maple syrup
- 1/3 cup cocoa powder
- 1/2 cup rolled oats
- 2 tablespoons ground flaxseed
- 1/4 cup water
- 1 teaspoon vanilla
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 1/3 cup chocolate chips
Method
- Heat oven to 350°F. Line 8-inch pan. Stir flaxseed and water; stand 5 minutes.
- Process beans, peanut butter, maple syrup, cocoa, oats, flax mixture, vanilla, baking powder, and salt until completely smooth.
- Fold in half the chips. Spread in pan and add remaining chips.
- Bake 24–30 minutes until edges set and center tester has moist crumbs, not wet batter. Cool fully before 16 squares.
Substitutions
Sunflower butter may replace peanut butter. Certified gluten-free oats may be used if needed.
Storage and safety
Store covered 2 days room temperature or 5 days refrigerated. Freeze squares up to 2 months.
Creating a smooth batter
Rinse black beans until the water runs clear, then drain for five minutes. Remaining canning liquid can create a beany aroma and loose center. Process the beans and wet ingredients before judging texture; the finished batter should look glossy with no visible bean skins. Scrape the processor bowl twice, especially beneath the blade hub.
How the binders work
Ground flaxseed and water replace egg by forming a gel during the five-minute rest. Rolled oats provide starch and body without conventional flour, while peanut butter supplies fat and structure. This recipe contains oats even though it contains no wheat flour; use certified gluten-free oats only when required. Conventional smooth peanut butter gives more predictable consistency than separated natural peanut butter.
Baking and slicing cues
Spread batter evenly into all corners of the 8-inch pan. The surface should lose its wet shine, edges should look set, and a tester should show moist crumbs rather than liquid batter. Cool completely in the pan before lifting by parchment; warm squares are fragile. Chill for especially neat cuts, wiping the knife between each of 16 portions.
Additional recipe guidance
The batter depends on a powerful food processor; a coarse mash leaves detectable bean skins and uneven oat pieces. Process for a full two minutes after the mixture first looks combined. Stop if the motor overheats, scrape, and resume. The flax mixture should look slightly viscous before it enters the processor. Because this is egg-free, the main doneness signs are a dry-looking edge, loss of wet surface shine, and moist—not liquid—crumbs on a tester. The center firms considerably during cooling, so cutting warm brownies creates a false impression of underbaking. For cleaner flavor, use fresh cocoa and rinse beans well. Serve at room temperature for a fudgy texture or chilled for a denser square.
