Ingredients
Method
- Choose the right mug: Use a microwave-safe mug that holds at least 10 to 12 ounces.A wider mug helps the cake cook more evenly.
- Mix the dry ingredients: Add almond flour, sweetener, baking powder, and salt to the mug. Stir well with a fork to break up any lumps.
- Whisk the wet ingredients: In the same mug, add the egg, melted butter, almond milk, vanilla, and almond extract. Stir until the batter looks smooth and evenly combined.
- Scrape the sides: Use the back of the spoon to scrape batter from the sides of the mug so nothing burns during cooking.
- Microwave: Cook on high for 60 to 90 seconds.Start with 60 seconds, then check. The top should look set and spring back lightly when touched.

- Rest: Let the mug cake stand for 1 minute.This helps the crumb set and keeps it tender.
- Top and serve: Add whipped cream, sliced almonds, or cinnamon if you like. Enjoy warm straight from the mug or tip it onto a plate.

Why This is Good for You
- Low in carbs: Almond flour keeps the net carbs down while giving a satisfying cake-like texture.

- No added sugar: Using a keto-friendly sweetener avoids blood sugar spikes.
- Protein boost: The egg adds structure and a bit of protein to help with satiety.
Pitfalls to Watch Out For
- Overcooking: A few extra seconds can turn the cake dry. Stop as soon as the center is set.
- Wrong flour: Almond meal is coarser and can make the cake gritty. Choose fine almond flour for the best texture.
- Too much sweetener: Some sweeteners can taste cooling or bitter in higher amounts.Start with 1 tablespoon and adjust next time.
- Uneven heating: Microwaves vary. If your cake rises then sinks, try lowering the power to 80% and cook slightly longer.
- Soggy bottom:</-strong> If the mug is very narrow, the center may stay wet. Use a wider mug and mix thoroughly.
Recipe Variations
- Lemon almond: Add 1 teaspoon lemon zest and a squeeze of lemon juice.Swap vanilla for more almond extract if you like.
- Cinnamon roll: Stir 1/2 teaspoon cinnamon into the batter and sprinkle a bit more on top before cooking. Drizzle with a quick glaze of powdered sweetener and almond milk.
- Chocolate chip:</-strong> Fold in 1 tablespoon sugar-free chocolate chips for a melty, dessert vibe.
- Berry swirl: Swirl in 1 tablespoon mashed raspberries or blueberries. Microwave in short bursts to avoid overflow.
- Dairy-free: Use coconut oil instead of butter and almond milk or canned coconut milk for richness.
- Extra fluffy: Separate the egg, whip the white with a fork until frothy, then fold into the batter.It adds lift and softness.
- Protein boost: Replace 1 tablespoon of almond flour with 1 tablespoon unflavored or vanilla whey isolate. You may need a splash more liquid.
FAQ
Can I bake this in the oven?
Yes. Preheat your oven to 350°F (175°C).
Pour the batter into a greased ramekin and bake for 12 to 15 minutes, or until the center is set and springs back.
Which sweetener works best?
Erythritol blends, allulose, or monk fruit blends all work. Allulose tends to keep cakes moist, while erythritol gives a cleaner sweetness but can be slightly drier. Adjust to taste.
Can I make it without egg?
You can try a flax “egg” (1 tablespoon ground flaxseed + 2.5 tablespoons water, rested 5 minutes).
The texture will be denser and less fluffy, but still tasty.
Why did my mug cake turn rubbery?
It’s usually from overcooking or using too much liquid. Next time, cook in shorter bursts and stop as soon as the top sets. Measure liquids carefully and stir until just combined.
How many carbs are in this?
Exact counts depend on your ingredients, but typically expect around 4 to 6 net carbs per mug cake when using almond flour and a zero-calorie sweetener.
Can I double the recipe?
Yes, but use a larger bowl or split into two mugs.
Doubling in one mug often leads to uneven cooking. If microwaving a larger portion, increase cook time gradually and check often.
Is almond extract necessary?
It’s optional, but a small amount adds a lovely bakery-style flavor that pairs perfectly with vanilla. If you don’t have it, use extra vanilla.
What if I don’t have almond milk?
Any low-carb milk works, like coconut milk (carton) or heavy cream for extra richness.
You may need a tiny splash more if using thicker cream.
