Preheat oven to 350°F (175°C). Line an 8x8 inch pan with parchment paper.
Make flax egg: Combine 2 tbs flaxmeal with 5 tbs water. Let sit to thicken.
In a large bowl, mix almond butter, plant milk, melted butter, and all coconut sugar until smooth.
Stir in the thickened flax egg.
In a separate bowl, whisk flour, baking powder, and salt.
Gradually mix dry ingredients into wet until just combined.
Fold in chopped chocolate.
Spread batter into the prepared pan.
Bake for 20-25 minutes until edges are golden and a toothpick comes out clean.
Cool completely in the pan before slicing.
