Notes
Store: Refrigerate in an airtight container for up to 5 days. Do not leave sitting out, mold could develop.
Freeze: In an airtight container up to 3 months.
Black beans: No substitutions, not even lentils. If you have homemade beans, use about 1 1/2 to 1 3/4 cups.
Other dates: Best to use Medjool dates. I tried "regular" dates and didn't love results but you can use them. Soak 15 dates in warm water for 15 mins and drain well.
Line baking dish with parchment paper: It makes brownies easy to cut and remove, and ensures they do not fall apart.
Let brownies cool off almost completely before slicing: I know it's hard, but please have patience.
