*Optional: I melted 3 oz chocolate chips (or sugar free chocolate chips) with a little oil and spread it over the bars after chilling.Preheat oven to 350 F. Mix brownie ingredients. Spread evenly into a greased or lined 8x8 pan. Smooth down with a sheet of parchment if needed. Blend cheesecake ingredients until smooth, using a regular or immersion blender or food processor. Spread on top of brownie layer. Bake 25 minutes on the center rack. Don’t open the oven door (not even to check), but turn off heat and let sit 8 minutes. Take out the undercooked bars and let cool completely, then refrigerate a few hours until firm. View Nutrition Facts
