Take the 4 eggs, butter, cream cheese, and yogurt out of the fridge at least 15 minutes before you start so they can warm up a bit. Preheat oven to 350˚F. Butter a 8×8″ brownie pan.
Brownie part:
Make the mud bean brownie batter and pour half of it into the pan.
Cheesecake part:
Beat together all the ingredients. Optional to add food coloring for some spunk!
Spread on top of the brownie batter in pan.
Combining:
Add the remaining brownie batter on top of the cheesecake layer in blobs. Use an offset spatula or knife to make patterns on the surface.
Bake at 350˚F for 35-40 minutes, until top is cracked and slightly browned. Let cool completely before cutting–this is super important! Also really good with a dollop of whipped cream on top.
