Blend 8oz cottage cheese in a small food processor until smooth and transfer to an oven-safe dish.
Crack in 2 eggs and mix until combined.
Add cacao powder (adjust for desired darkness). I like 3 tbsp, but you do you.
Stir in 3–4 tbsp powdered monkfruit or preferred sweetener.
Add a splash of vanilla extract and mix thoroughly.
Sprinkle chocolate chips on top, if desired, and add 1–2 tsp peanut butter inside. To make this lower-calorie, skip the PB here and just top with the lighter PB frosting below. Shake gently so it submerges into the cake.
Bake at 350°F for 30–35 minutes.
Remove, let cool for 2 minutes, then enjoy!
