Why you'll love this mug
- 7g protein — egg and almond flour
- 3g net carbs — allulose, not sugar
- About 5 minutes, one mug
- Pale cake, spoon lift, chocolate shavings, like the photo

Health notes
- Protein: The egg and almond flour carry the mug.
- Lower carb than a bakery mug cake: No wheat or sugar. Close to keto at 3g net.
- One mug: Macros are the whole cup, shavings included.
- Regular sugar or a sweet chocolate bar will jump the carbs. Keep the shavings small.
Key element — short microwave, soft center
A rubber cake ran too long. Microwave until it rises and the center still gives, then add the dust and shavings, like the photo.
Ingredients
Mug (1 serving)
- 3 Tbsp almond flour
- 1 Tbsp allulose
- 1/2 tsp baking powder
- 1 large egg
- 1 Tbsp melted butter
- 1/2 tsp vanilla extract
- Pinch of salt
Top
- 1 tsp powdered allulose
- 1 tsp sugar-free chocolate shavings
Swaps
- Coconut flour: Use 1 Tbsp, not 3. It drinks more liquid.
- Oil: Swap the butter if you want.
- Sugar or wheat flour: Skip them. That is how carbs jump.
Instructions
| 1 | Mug. Use a microwave-safe mug that holds at least 12 oz. Set it on a saucer. |
| 2 | Mix. Stir almond flour, allulose, baking powder, and salt. Add the egg, butter, and vanilla. Mix until smooth. |
| 3 | Cook. Microwave on high 60 to 75 seconds until it rises. Stop while the center still looks soft. |
| 4 | Rest. Let it sit 1 minute. It finishes as it cools. |
| 5 | Top. Dust with powdered allulose and chocolate shavings, like the photo. The whole mug is one serving. |
Pro tips
- A wide mug rises better than a narrow cup.
- 60 seconds first. Add 10 seconds only if the center is raw.
- Overcooking makes a rubber cake.
- Use sugar-free shavings, not a sweet bar.
- A spoon lift matches the photo. Eat it warm.
