Note: It’s best to use warm temperature ingredients for the cheesecake layer. If you haven’t already, set the cheesecake layer ingredients somewhere warm (like above the preheating oven).
Preheat oven to 325°F (163°C).
Grease a 13”x9” (33c x 23) baking pan and set aside.
Brownie Mix: In a large mixing bowl, combine brownie mix and eggs. While whisking to combine, pour in the melted butter. Once well mixed, set aside.
Bayou Brownie Mix: In a separate large mixing bowl, combine chopped pecans, sweetener, optional polydextrose, ground chia, almond flour, coconut flour, protein powder, baking powder and salt. Whisk to combine.
To the second large mixing bowl, add the eggs, almond milk and vanilla. Whisk to start combining. While whisking, pour in the melted butter. The chia seeds will start to absorb moisture and thicken the batter. Set aside.
Cheesecake Topping: In a clean large mixing bowl (an electric mixer is best for this), add the room temperature cream cheese, powdered sweetener, sour cream, eggs, vanilla and salt. Whip the ingredients until smooth. If there are any lumps, you can always push the cheesecake batter through a strainer.
I personally used a big ice cream scoop for this. I put drops of brownie batter around the bottom of the pan. Then, I put drops of bayou brownie batter between the other drops. Then, I just continued to drop random blops of the two batters in a haphazard manner on top of one another. This kind of combines them into a patchwork pattern of batters. You can do this with a spoon, too. Or, you can marble the two batters in a bowl and pour it in, but I kinda like this method. Once both batters are in the pan, use a spatula to flatten the top.
Gently spoon the cheesecake batter over the top of the brownie(s) layer. With a plastic spatula evenly smooth and spread the cheesecake over the top.
Bake for 20 minutes, then turn the oven to 300°F (148°C).
Bake a further 20 minutes, or until the cheese mixture has a mild tan and has solidified. Once they’re done, leave the pan in the oven, but turn the oven off and allow them to cool slowly.
A few hours later, return to the oven, remove the tray, slice and share with friends!
