• 3 Medium bananas, mashed
• 170 g Nonfat Greek yogurt, 0% (For the banana batter)
• 120 ml Unsweetened almond milk (For the banana batter)
• 60 ml Egg whites (For the banana batter)
• 120 g Oat flour (For the banana batter)
• 60 g Vanilla casein protein (Approximately 2 scoops)
• 30 g Vanilla whey protein (Approximately 1 scoop)
• 60 g Granulated sugar substitute (For the banana batter)
• 1 Medium egg (For the brownie batter)
• 30 g Egg whites (For the brownie batter)
• 85 g Nonfat Greek yogurt, 0% (For the brownie batter)
• 7.5 g Coconut oil (Melted)
• 2.5 ml Vanilla extract (Optional)
• 90 g 1:1 granulated sugar substitute (The source indicates 90–100 g; Swerve or Lakanto may be used)
• 17 g All-purpose flour (For the brownie batter)
• 22 g Cocoa powder (It is not specified whether it is sweetened; baking cocoa powder is assumed)
• 25 g Chocolate protein powder (For the brownie batter)
• 1.5 g Baking powder
• Salt (A pinch)
• Chocolate chunks or chips (Optional; sprinkle on top. Not included in the macronutrients)

Steps

1. 1

   Preheat the oven to 350 °F (175 °C). Line a loaf pan or lightly grease it.

2. 2

   Prepare the banana batter: mix the mashed bananas, Greek yogurt, almond milk, and egg whites until well combined.

3. 3

   Add the oat flour, vanilla casein, vanilla whey protein, and sugar substitute. Mix just until combined; do not overmix.

4. 4

   In a separate bowl, whisk together the egg, egg whites, Greek yogurt, melted coconut oil, and optional vanilla extract.

5. 5

   Add the 1:1 sugar substitute, flour, cocoa powder, chocolate protein powder, baking powder, and pinch of salt. Mix until you have a thick, smooth brownie batter.

6. 6

   Pour some of the banana batter into the pan. Add spoonfuls of the brownie batter over the top, and continue alternating layers until both batters have been used.

7. 7

   Gently run a knife or skewer through the batters to create a marbled effect without fully mixing them together.

8. 8

   If desired, sprinkle chocolate chunks or chips over the surface.

9. 9

   Bake until the center is set and a toothpick comes out nearly clean. Start checking at 50–60 minutes.

10. 10

    Let cool before cutting into 8 thick slices.
