Ingredients:

To make this delicious keto lemon mug cake, you’ll need the following ingredients:

Wet Ingredients:

  1. 1 large egg – The egg will help bind the ingredients together and provide moisture to the cake.
  2. 1 tablespoon melted butter – Butter adds richness and ensures the cake remains moist.
  3. 1 tablespoon heavy cream – Heavy cream adds a smooth texture and enhances the overall richness of the cake.
  4. 1 teaspoon lemon juice – Freshly squeezed lemon juice imparts a zesty citrus flavor that defines the cake.
  5. 1 teaspoon vanilla extract – This complements the lemon flavor, adding a subtle sweetness.

Dry Ingredients:

  1. 2 tablespoons almond flour – A keto-friendly flour that is low in carbs, high in fat, and full of fiber.
  2. 1 tablespoon coconut flour – Coconut flour helps to absorb moisture and adds a slight coconut flavor. It also helps in giving the cake structure.
  3. 1/4 teaspoon baking powder – Helps the cake rise and become fluffy.
  4. 1 tablespoon erythritol (or your preferred sweetener) – A sugar substitute that provides sweetness without adding carbs. Adjust the quantity based on your preferred sweetness.
  5. Pinch of salt – Salt enhances the flavors and balances the sweetness.

Optional:

  • Zest of 1/2 lemon – For an even more intense lemon flavor.
  • Sugar-free whipped cream (for topping) – Adds an indulgent finishing touch if desired.

Instructions:

Step 1: Prepare Your Mug

Start by selecting a microwave-safe mug, ideally one that holds around 8 ounces of liquid. You want enough room for the cake to rise without overflowing.

Step 2: Add Wet Ingredients

In the mug, whisk together the following wet ingredients:

  • 1 large egg
  • 1 tablespoon melted butter
  • 1 tablespoon heavy cream
  • 1 teaspoon lemon juice
  • 1 teaspoon vanilla extract

Mix until smooth and well combined.

Step 3: Mix in Dry Ingredients

Next, add the dry ingredients to the wet mixture:

  • 2 tablespoons almond flour
  • 1 tablespoon coconut flour
  • 1/4 teaspoon baking powder
  • 1 tablespoon erythritol (or sweetener of your choice)
  • Pinch of salt

Stir until everything is thoroughly combined. The batter should have a slightly thick consistency.

Step 4: Microwave the Mug Cake

Place the mug in the microwave and cook on high for 60-90 seconds, depending on your microwave’s power. Start with 60 seconds and check the cake. If the center is still too wet, cook for an additional 15-30 seconds. The cake is ready when it has risen and is firm to the touch.

Step 5: Serve & Enjoy

Let the cake cool for a minute or two before eating. If desired, top it with a dollop of sugar-free whipped cream or a drizzle of extra lemon juice for an additional burst of flavor.

Useful Tips for Success:

  • Microwave Variability: Microwaves can vary in power, so start with less time and check the cake after each interval to prevent overcooking. If overcooked, the cake may become dry.
  • Almond Flour: For best results, use finely ground almond flour. Coarse almond flour may affect the texture and result in a crumbly cake.
  • Coconut Flour: Coconut flour absorbs moisture, so you might need to adjust the amount of heavy cream or butter if you prefer a moist cake. If the batter seems too thick, add an extra teaspoon of heavy cream.
  • Flavor Variations: Feel free to experiment with other extracts, such as lemon or almond extract, to adjust the flavor to your liking. You can also mix in a few sugar-free chocolate chips for an indulgent twist.
  • Storage: If you make extra, store leftover cakes in an airtight container in the fridge for up to 2-3 days. Reheat in the microwave for about 15-20 seconds before serving.
