Ingredients:
- 4 tablespoons almond flour (or any low-carb flour of choice)
- 1 tablespoon coconut flour
- 1/4 teaspoon baking powder
- 2 tablespoons granulated erythritol or any sugar-free sweetener
- 1 large egg
- 2 tablespoons unsweetened almond milk (or any milk of choice)
- 1 tablespoon lemon juice
- 1/2 teaspoon lemon zest
- 1/2 teaspoon vanilla extract
- 1 tablespoon melted coconut oil or butter
- A pinch of salt
Instructions:
- Prepare the Mug: Choose a microwave-safe mug that can hold at least 12 ounces to prevent the batter from spilling over as it cooks. Lightly grease the inside of the mug with a bit of melted coconut oil or butter to ensure the cake doesn’t stick.
- Mix Dry Ingredients: In a small mixing bowl, combine the almond flour, coconut flour, baking powder, granulated erythritol, and a pinch of salt. Stir until all the ingredients are well blended.
- Add Wet Ingredients: To the dry ingredients, add the egg, unsweetened almond milk, lemon juice, lemon zest, vanilla extract, and melted coconut oil or butter. Mix thoroughly with a fork or small whisk until a smooth batter forms. The batter should be thick but pourable. If it’s too thick, add a little more almond milk, one teaspoon at a time.
- Microwave the Cake: Pour the batter into the prepared mug. Tap the mug on the counter gently to remove any air bubbles and to level the batter. Place the mug in the microwave and cook on high for 1 minute and 30 seconds. Microwave times may vary depending on your microwave’s wattage, so you may need to adjust the time slightly. Start checking at 1 minute. The cake is done when it has risen and is firm to the touch. If it’s not fully cooked, continue microwaving in 10-second intervals until done.
- Cool and Serve: Let the cake cool in the mug for a minute or two. This helps the flavors to settle and makes it easier to handle. You can enjoy the cake directly from the mug or gently loosen the edges with a knife and transfer it to a plate.
- Optional Toppings: To enhance the flavor, consider topping your lemon mug cake with a dollop of sugar-free whipped cream, a sprinkle of additional lemon zest, or a few fresh berries. You can also dust a bit of powdered erythritol on top for a touch of sweetness.
