Preheat your oven to 350°F and line a small square baking dish with parchment paper.
Place the silken tofu, egg whites, cocoa powder, almond flour, and monk fruit sweetener into a blender.
Blend on high until the mixture is completely smooth and resembles a thick batter.
Fold in the dark chocolate chips by hand using a spatula.
In a separate small bowl, stir the low-fat cream cheese until it is smooth and spreadable.
Pour the chocolate brownie batter into the prepared baking dish.
Drop small spoonfuls of the cream cheese onto the top of the batter.
Use a toothpick or the tip of a knife to gently swirl the cream cheese into the chocolate batter to create a marble pattern.
Bake for 25 to 30 minutes until the edges are firm but the center still has a slight jiggle.
Remove from the oven and let the brownies cool completely in the pan to allow the protein structure to set before slicing.
