High-Protein Vanilla Mug Cake
High-Protein Keto Vanilla Mug Cake
Low carb • Sugar-free vanilla mug cake — 5 minutes, one mug
This is a high-protein keto vanilla mug cake, not a sugar microwave sponge. Almond flour, protein powder, and an egg cook in a ramekin, then get whipped cream, sugar-free chocolate drizzle, and chips, like the photo. Five minutes. No wheat flour, no sugar.
One mug is one serving. Stop the microwave when the top is just set.

Why you’ll love this mug cake
- 16g protein per cake — egg and protein powder
- 3g net carbs — almond flour and allulose
- About 5 minutes, one mug
- Vanilla crumb, whipped cream, chocolate drizzle, like the photo
- No boxed mix, no sugar
- It stays soft if you do not overcook it
Health notes
- Protein: High for a single mug. Egg and whey carry it.
- Lower carb than a bakery mug cake: Almond flour and allulose. Close to keto-zero at 3g net.
- One cake: Macros include a measured topping, not a pile of chips.
- Wheat flour or sugar syrup will jump the carbs. Stay almond and sugar-free drizzle.
Key element — a short cook, then the toppings
Overcooked mug cake turns rubber. Mix the batter in the ramekin, microwave 60 to 90 seconds until the top is just set, then add whipped cream, sugar-free chocolate drizzle, and a few chips, like the photo.

Ingredients
Instructions
- Mix dry. In a 10-ounce ramekin, stir almond flour, protein powder, allulose, baking powder, and salt.
- Wet. Add egg, cream, and vanilla. Stir until no dry pockets remain.
- Cook. Microwave 60 to 90 seconds until the top is just set and the center is still soft.
- Rest. Wait 30 seconds so the crumb finishes.
- Top. Add whipped cream, sugar-free drizzle, and chips, like the photo. One mug is one serving.
Notes & Tips
- Start at 60 seconds. Extra time turns the cake rubbery.
- Use a 10-ounce mug so the batter has room to rise.
- Stir the bottom. Dry pockets stay raw.
- Keep the chips to 1 tsp so the carbs stay at 3g net.
- Eat it warm. Mug cake firms as it cools.
Variations & serving ideas
- Egg white protein: Same 1 Tbsp if you want a leaner crumb.
- Butter: 1 Tbsp melted butter in place of cream.
- Wheat flour or sugar syrup: Skip them. That is how carbs jump.
- Chocolate: Add 1 tsp cocoa to the dry mix.
- Cinnamon: Add 1/4 tsp cinnamon with the vanilla.
- Peanut butter: Stir 1 tsp natural peanut butter into the batter.
- Oven: Bake at 350 F for 12 to 14 minutes if you do not want the microwave.
Storage
- Eat now: Best (While warm with the topping)
- Refrigerator: Up to 1 day (Reheat 15 seconds. Top after)
- Freezer: Skip (Mug cake dries after thaw)

Frequently asked questions
Is this mug cake keto-friendly?
Yes. About 3g net per cake with almond flour and allulose. Skip wheat flour and sugar syrup.
Why is it rubbery?
It cooked too long. Start at 60 seconds and stop when the top is just set.
Can I use wheat flour?
It adds carbs. Stay with almond flour so the cake stays at about 3g net.
Why is the center wet?
It needed another 10 to 15 seconds, or the dry mix was not stirred through.
Do I have to add the topping?
No. The cake is the serving. The photo topping is a measured spoon of cream, drizzle, and chips.
How do I store leftovers?
Eat it now. If you must wait, cover and fridge 1 day, then warm 15 seconds.
