Make the no-bake brownie base as per the instructions in the recipe and press the dough firmly into a baking pan (lined with foil or parchment paper). My pan measures 8 1/2 x 6 inches. If you use a bigger pan the bars will be less thick. You can also leave out the brownie base completely for this recipe and just make the cookie dough layer and chocolate layer.
For the cookie dough layer, process chickpeas, sunflower seed butter and vanilla extract in a food processor or blender until smooth and creamy. Add all other ingredients (except the chocolate chips) and mix again. Stir in the chocolate chips with a spoon. Transfer the cookie dough mixture to the pan and put it in the freezer.
For the chocolate fudge layer, carefully melt the cacao butter in a water bath, add all other ingredients, stir with a whisk, and pour it onto the cookie dough layer. Put the pan in the freezer for about 60 minutes to set.
Cut into bars and enjoy thawed. Store leftovers in the fridge. Enjoy!
You can use cooked white beans instead of cooked chickpeas.
Any other nut/seed butter (e.g. almond butter, coconut butter, cashew butter, peanut butter etc) is fine.
You can use Xylitol, coconut sugar, or regular sugar instead of Erythritol. To make powdered sugar, just process it in a blender or an electric coffee/spice grinder for a couple of seconds. I use this small electric coffee/spice grinder which I love: https://amzn.to/2PrXv8r
