Prep the flax eggs: Mix flaxseeds and water in a small bowl. Let sit for 5-10 minutes to thicken while you prepare the rest of the brownie batter.
Make the brownie batter: In a food processor, combine black beans, almond flour, cocoa powder, maple syrup, vanilla, almond butter, salt, and baking powder. Add the flax mixture. Blend until smooth. Fold in chocolate chips.
Bake: Divide batter into a greased mini muffin tin (about 24 wells). Bake at 375°F for 12 minutes, until the tops are set. (They will be very soft when taking out of the oven, allow to cool 10 minutes in the tin at least).
Make the jam: While brownies bake, mash strawberries with a fork, stir in chia seeds and maple syrup, and let sit for 10 minutes to thicken.
Assemble: Once brownies have cooled slightly, press a small indent into each and fill with about ½ teaspoon of strawberry chia jam. Cool completely before serving. Store in the fridge in an airtight container for 3 days or freeze for 2 months.
