40 Second Keto Lemon Cupcakes

You don’t have to wait for a special occasion or dirty the entire kitchen to enjoy a few cupcakes! These light and delicious cupcakes bake in the microwave in about 40 seconds. Normally, I don’t think about the microwave when I want to bake a cake, but I have found that keto mug cakes made in a microwave rise beautifully and have a light, tender crumb. Just be sure you don’t overcook them or they can become tough. Silicone cupcake liners are microwave-safe, come in a variety of fun colors, are non-stick and hold their shape during cooking, so that’s what I use. (You can use paper liners, but you’ll need to support them in a microwave-safe cup so the cupcakes retain their shape during the cooking process. If you decide to use paper liners, make sure there is no metal in the liner or its printed design.) This quick recipe makes only three cupcakes, which is just enough to share with one or two friends. There’s no reason not to have a little party tonight!

40 Second Keto Lemon Cupcakes

Makes 3 cupcakes

Cupcake Ingredients:

1/4 cup almond flour

2 teaspoons coconut flour

1 tablespoon granulated erythritol sweetener

1/2 teaspoon baking powder

A pinch of salt

1 large egg

1 teaspoon lemon juice (or almond milk)

1/2 teaspoon lemon zest (or 1-2 drops of food grade lemon essential oil)

1/2 teaspoon vanilla extract

5 drops monkfruit extract (or liquid stevia)

1 teaspoon melted butter or ghee

Lemon Cream Frosting:

2 ounces cream cheese, room temperature 

2 tablespoons unsalted butter, softened

4 ounces plain mascarpone cheese, room temperature

1/4 cup powdered erythritol sweetener 

1 teaspoon vanilla extract

1/4 to 1/2 teaspoon lemon extract, to taste

1-2 tablespoons heavy cream

Sugar free sprinkles (optional)

1. In a small bowl, combine the first five dry ingredients (almond flour through salt) with a fork until thoroughly mixed; set aside.

2. In a separate bowl, whisk together the egg, lemon juice or almond milk, lemon zest, vanilla extract, monkfruit extract or stevia and melted butter.

3. Add the dry ingredients to the wet ingredients and whisk until just combined. Divide the batter equally among three silicone cupcake liners (or small greased ramekins). Microwave on high for 35-40 seconds or until the cakes have risen, look dry and the tops spring back when lightly touched in the center. Do not overcook! (Note: Cooking time may vary depending on the wattage of your microwave. Instructions for baking in the oven are provided below.*) Remove the cupcakes from the microwave and cool on a wire rack completely while you make the frosting.

4. To make the frosting: Whip together the room temperature cream cheese, butter and mascarpone cheese with an electric mixer until light and fluffy. Add the powdered sweetener, extracts and beat until combined. Add the heavy cream, one tablespoon at a time, until your frosting reaches the desired consistency. Taste and adjust sweetness to your liking. If desired, spoon the frosting into a piping bag with a decorating tip and frost your cupcakes or spread about 3 tablespoons of frosting onto each cupcake.

5. This frosting recipe yields more than you will need for 3 cupcakes, which allows for dividing into batches and coloring each differently using gel food colors (as shown). Store any leftover frosting in an airtight container in the refrigerator and save for another use. It will keep well for 4-5 days. Bring to room temperature and rewhip if needed to restore spreading consistency. 

*To bake the cupcakes in the oven, bake in a preheated 325 degree F oven for 16-18 minutes or until a toothpick comes out clean when tested and the tops spring back when lightly touched near the center.
