Preheat the oven to 180 C / 350 F.
Add all the ingredients except the chocolate chips to a food processor / blender and mix until smooth. (I use this stevia powder.)
Fold in the chocolate chips.
Pour the batter into a 8 x 8 inch (20 x 20 cm) pan (or a smaller pan) lined with parchment paper.
Bake for 20 - 25 minutes.
Let cool for 15 minutes.

I always use SweetLeaf Stevia Powder for baking, so even though I provide the amount of other sweetener equivalent to Stevia in each recipe, that might end up in a different texture than mine.
