Ingredients

1 scoop 25–30g protein powder (whey or plant-based)
2 tbsp 30g mashed banana or unsweetened applesauce
2 –3 tbsp milk oat milk, dairy, almond, soy, etc.; adjust as needed
Optional not counted in 3 ingredients, but mentioned in article:

pinch of baking powder (optional)

optional toppings: peanut butter Greek yogurt, cocoa powder, berries, nuts

Instructions

Step 1: Mix the Ingredients

In a microwave-safe mug or small bowl, add:
1 scoop protein powder
2 tbsp mashed banana or applesauce
2 tbsp milk
Stir until you get a smooth batter.
If too thick, add 1 more tbsp milk. If too runny, add a bit more protein powder.
Optional: add a pinch of baking powder for extra fluffiness.

Step 2: Microwave

Microwave on high for 45 to 60 seconds.
Check the center — if it’s still wet, microwave for 10–15 seconds more.
Do not overcook — the center should be just set and spongey.

Step 3: Let It Sit

Let it rest for 1 minute before eating for better texture and safety.

Notes

For extra softness, try mashed banana and oat milk — they always give the best texture without needing more ingredients.
