    This easy lime gluten free mug cake with lime icing is moist and delicious. Even better? It cooks in your microwave in just 90 seconds! No hot oven needed; which is awesome because it is too hot to use the oven now. (Dairy-free too!)

    Doesn't this gluten free AND dairy-free lime cake look delicious? I was worried the microwave would dry it out, but it didn't dry at all. Each bite is bursting with lime flavor! This mug cake has lime icing, but you could easily use a regular frosting and make this a cupcake in a mug!

    Our weather has been so much hotter than usual here in the Bay Area, and it is just the beginning of summer here! What is a dessert-loving family with a wicked sweet tooth to do?

    I will be creating a lot of fun mug cake recipes over the next few months if the weather stays this hot. (Global warming is so real!)

    If you love the idea of making and eating the cake in under 5 minutes, check out all of my incredible gluten free mug cake recipes!

    Why this recipe is so good:

    This quick and easy lime mug cake is full of juicy lime flavors. Topped with a sweet icing to balance out the tartness, this cake is so good. I still can't believe how fast you can make this!

    Use the microwave for this gluten free mug cake! I know it sounds funny, but you can get a moist and delicious cake in your favorite mug! You can make this gluten free microwave cake in so many flavors, like this Gluten Free Cherry Cobbler Mug Cake.

    Ingredient notes:

    gluten free lime mug cake ingredients
    • Gluten free flour blend - I tested this recipe using Bob's Red Mill 1 to 1 Gluten Free Flour Blend and King Arthur's Measure for Measure Gluten Free Blend. That doesn't mean others will not work, I just have not tested other flours.
    • Xanthan gum - If your gluten free flour blend doesn’t contain xanthan gum or guar gum, please add 1 teaspoon.
    • Almond milk - I used almond milk but other dairy-free kinds of milk will work but I do not recommend canned coconut milk

    How to make a gluten free lime mug cake:

    If you have wondered how to make a gluten free version of a mug cake, just follow along!

    a mug with baking powder and lots of lime zest on a cutting board

    Step 1: Zest and juice your limes. This cake is full of fresh lime flavors. I not only use lime juice but lots of lime zest too!

    Step 2: Add your wet ingredients to a small bowl and whisk to blend. Add your dry ingredients and mix.

    Lime cake batter in a bowl

    Here is the lime cake batter. Notice the consistency is not thick....this helps keep the cake light and fluffy.

    Step 3: Spray your mug lightly with spray oil.

    Step 4: Pour the cake batter into your favorite mug and microwave on high for 90 seconds. The mug cake will rise up, then fall as it cooks. Be careful because the cooked cake will be hot.

    Tips and Recipe FAQ:

    How do you know when the mug cake is done cooking?

    You can do the toothpick test, but it isn't as accurate because of the texture of the cake. I like to touch the top of the cake. If it feels firm, the cake is done cooking.

    Can you use other flavors like lemon?

    You can easily switch out the lime for lemon to make this a lemon cake.

    Can you bake this in the oven?

    You could bake this mug cake in the oven, but that defeats the whole cake in 3 minutes excitement.

    Is it possible to make mug cakes less spongy?

    The sponginess comes from using oil. If you are okay with dairy, use butter for a lighter, fluffier texture and mouthfeel.

    How do you get the cake out of the mug?

    I spray my mug lightly with light oil spray. This helps the mug cake slide out easier.

    Ingredients
      

    • 3 tablespoons gluten free flour blend * see note
    • ½ teaspoon baking powder
    • 1 egg large
    • 3 tablespoons sugar
    • 2 tablespoons coconut oil
    • ½ teaspoon pure vanilla extract
    • 2 tablespoons lime juice
    • 1 teaspoon lime zest

    For the Icing

    • 3 tablespoons powdered sugar for icing
    • 1 teaspoons lime juice for icing

    Instructions
     

    • In a small bowl, add flour, sugar, and baking powder. Add in the egg, melted coconut oil, lime juice, and lime zest.
    • Mix well. Pour into your favorite mug. (I used a spray coconut oil to spray the sides of the mug so the cake doesn't stick.)
    • Put into the microwave for 90 seconds.
    • Put the powdered sugar and lime juice in a small bowl and mix. Drizzle onto the mug cake.

    Notes

    1. I have tested this recipe with King Arthur Measure for Measure GF and Bob's Red Mill 1 to 1 GF blend.. That doesn't mean others will not work, I just have not tested other flours.
    2. If your gluten free flour blend doesn’t contain xanthan gum or guar gum, please add 1 teaspoon.
    3. I used almond milk but other dairy-free kinds of milk will work but I do not recommend canned coconut milk.
    4. To test for doneness, touch your finger to the top of the cake. If it feels firm, your cake is done cooking.
    5. Make sure your mug is microwave safe!
