The Method for Keto Lemon Mug Cake

Making this Keto Lemon Mug Cake is a breeze! With just a few simple steps, you’ll have a delicious dessert ready in no time. Let’s walk through the process together, ensuring you capture all the delightful flavors and textures along the way.
Start by greasing 2 ramekins, mugs, or a microwave-safe bowl with melted butter. I personally prefer using a glass dessert bowl for its even cooking. Make sure to coat the sides well so the cake comes out easily.
In a separate bowl, mix all the dry ingredients: almond flour, powdered sweetener, and baking powder. This step is crucial as it ensures even distribution of the leavening agent.
Add all the wet ingredients including the egg, heavy cream, and lemon juice into the dry mixture. Use a fork to mix thoroughly until you have a smooth batter. If the mixture appears too liquid, don’t hesitate to add a little more almond flour to achieve your desired consistency.
Transfer the batter into your prepared bowl or mugs. Level the top with a spatula or the back of a spoon. This ensures an even rise while cooking.
Microwave on high for 90 seconds. Depending on your microwave’s wattage, you might need to adjust the time slightly. Just keep an eye on it – you want it to be fluffy and not overcooked.
Once the cake is done, let it cool for a minute or two. Carefully turn it upside down onto a plate or enjoy it straight from the bowl. The choice is yours!
For the glaze, melt the remaining butter, then stir in the heavy cream, lemon juice, and powdered sweetener. Allow it to cool until it begins to thicken. This adds a lovely touch to the cake.
Finally, spoon or pour the glaze over your cake. This step elevates the flavor and makes for a beautiful presentation.
Things Worth Knowing
- Microwave Wattage: Depending on your microwave’s wattage, the cooking time may vary. A 600W microwave may take longer than a 1000W one.
- Texture Check: The cake should be soft and fluffy. If it looks wet in the center, give it a few more seconds in the microwave.
- Storage: Store any leftovers in an airtight container in the fridge for up to three days.
