Ingredients
Mug cake (1)
- 1 scoop chocolate protein powder (about 30 g)
- 1 Tbsp almond flour
- 1 Tbsp cocoa powder

- ¼ tsp baking powder
- 1 large egg

- 1 tsp melted butter
- 1 Tbsp cream or Greek yogurt, to top
- 3 raspberries
Swaps

Instructions
| 1 | Mix. In a microwave-safe mug, stir protein powder, almond flour, cocoa, sweetener, and baking powder. Add the egg, almond milk, and melted butter. Stir until smooth. |
| 2 | Microwave. Cook on high 70–90 seconds. Stop when the center is just set and the top has domed. Do not go to 2 minutes. |
| 3 | Rest. Let it sit 1 minute. It finishes setting as it cools. |
| 4 | Top. Spoon on the cream and set 3 raspberries on it, like the photo. |
