Are you ready to give this dairy free lemon mug cake recipe a try?

🥘 Ingredients

• Gluten free flour blend
• Sugar
• Fresh lemon (for juice and zest)
• Light oil
• Egg
• Non-dairy milk

🔪 Instructions:

Add all of your dry ingredients to a bowl and whisk to blend. In another bowl, add the wet ingredients and whisk to blend.

I have tested two gluten free flour blends in this recipe. I liked King Arthur Gluten Free Measure for Measure and Bob's Red Mill 1 to 1 Gluten Free Flour Blend. This doesn't mean other blends won't work, I just haven't tested any others. Try to avoid flour blends that are high in starch.

As always, if your blend does not contain Xanthan Gum, you will need to add 1 teaspoon.

Pour the wet ingredients into the dry ingredients and mix well.

Can you use jarred lemon juice?

You can easily substitute jarred lemon juice for fresh lemon juice, but you won't have any fresh lemon zest if you use jarred. The rich lemon flavors will still shine through in the most delicious way!

Pour your cake batter into a mug. Microwave for 90 seconds. If you are using a deep coffee mug, you will want to add 20 seconds if it needs a bit more time.

Note: The cake is going to rise while cooking...A LOT. Make sure when you put the batter in the cup that it is no more than half full. The cake will grow way past the rim, then sink back down as it cooks.

Topping ideas:

There are so many fun ways to top this mug cake! Here are some of our favorites:

• Lemonade icing (recipe below)
• Vanilla frosting or vanilla cream cheese frosting (use the recipe in this cake recipe)
• Drizzle on melted white chocolate
• Whipped cream
• Vanilla ice cream

How long do you microwave cake?

For my mug cake recipes, I microwave my mug cakes for about 1 minute and 45 seconds. If you use a deep mug, you may need to microwave an additional 20 seconds.

This gluten free chocolate mug cake takes about 2 minutes because it is a double serving.

Can you use any mug?

You can use any mug to make a mug cake as long as it is microwave safe. Do NOT use plastic mugs as they can melt or add a chemical flavor to your cake. Make sure your mug is tall enough that the batter will come up no higher than half way.

How to make a mug cake pretty:

The only bummer to a mug cake is they just aren't pretty. If you need to make your mug cake look good, you can use a knife to make some simple cuts to make it more uniform.

Once your mug cake is a uniform shape, cut it in half horizontally so that it is like a layer cake. Frost as you would a regular layer cake.
