Ingredients and Substitutions
- Egg - This helps the mug cake rise in the microwave. If needed, you can substitute with a flax egg but be prepared that it won't rise as much.
- Honey - Used to sweeten the cake naturally. Agave or maple syrup will work as well.
- Coconut oil - Provides moisture to the cake batter. Any type of lightly flavored oil can used as a substitute like avocado oil or vegetable oil or melted butter.
- Almond milk - Any type of milk will work in this recipe.
- Lemon - Both fresh lemon juice and lemon zest are used. They add some fresh lemon flavor and will provide the best result. Store bought lemon juice can be used as well but I recommend using a little more to ensure the lemon flavor shines through in the cake.
- Flour - All purpose or gluten free 1:1 will work in this lemon mug cake recipe.
- Lemon curd - I used my own recipe for dairy free lemon curd but you can use any kind of lemon curd or make a lemon royal icing.
- Whipped cream - Store bought or fresh whipped cream can be used. Cool whip is also a great option or Truwhip if dairy free.
How To Make a Lemon Mug Cake
You will need a large coffee mug and a fork or spoon to mix the batter for this recipe.
Step 1 : Mix the wet ingredients. In a separate small bowl or in the bottom of your mug, whisk the egg, honey, coconut oil, almond milk, lemon juice, and vanilla together until well mixed.
Step 2 : Add the dry ingredients. Fold in the flour, lemon zest, and baking powder to the batter until just mixed. The batter should be slightly thick like pancake batter.
Step 3 : Microwave. Place the mug in the microwave and heat for 60 - 90 seconds. The cake will puff up in the mug. The top of the cake may look slightly wet which is okay, as it cools down it will firm up to resemble a slice of cake.
Step 4 : Top. Spoon a dollop of whipped cream on top of the mug cake followed by a spoonful of lemon curd and dig in!
What Can I Use Instead of Lemon Curd?
If you don't have lemon curd or don't want to go through the hassle of making a jar yourself, you can also top your mug cake with an easy lemon icing. Simply mix together 2 tablespoons of powdered sugar with a teaspoon of lemon juice and pour over top of the warm cake.
Expert Tips
- Don't over mix the cake batter. Even though this is a mug cake, you still want to be sure not to over mix the batter when the dry ingredients have been incorporated.
- Use a large mug to ensure the cake doesn't spill out of the mug. I used a 16 oz coffee mug and it was perfect.
- Remember that the mug will be hot when it's done in the microwave so I recommend waiting a few seconds to take it out.
- Drizzle the lemon curd or icing over the cake while it's still slightly warm. The warm cake will soak up the sweetness perfectly.
