Preheat oven to 350°F. Line an 8-inch square pan with parchment paper.
In a food processor, blend the chickpeas, almond butter, xylitol, stevia, vanilla, salt, cinnamon, and baking powder until perfectly smooth. Remove the blade and stir in the chocolate chips and goji berries.
Spread the batter in the pan and smooth the top. Bake for 25-35 minutes, until just beginning to brown on the edges and crack on top. Allow to cool completely before cutting into 16 squares. Store, covered, in the refrigerator for up to 5 days. May be frozen.
