There is one thing I miss the most when it comes to a gluten free lifestyle. Desserts are a must, and it is hard to find a gluten-free cake recipe that gives you the same texture and flavor as you would hope it to taste. Add the challenge of cooking the cake in the microwave oven, which can be tricky!

This is the ultimate microwave carrot cake recipe. It is gluten free and has an easy dairy-free option. You can top it with frosting, dust powdered sugar over the top, or enjoy it plain.

Why this carrot cake in a mug is so good:

  1. This mug cake is so tender, light, fluffy, and loaded with carrots, walnuts, and raisins for the perfect hint of sweetness. 
  2. It tastes as if you baked it! No joke, it is absolutely delicious!
  3. You can make the whole thing in under 5 minutes!!
  4. I made sure to add the right spices so you get that warm and inviting spice mix that has you hooked with one little bite. 

Made this today. Added raisins. So very good. Used grapeseed oil and oat milk due to other intolerance. Came out beautifully. Thank you.”

Allergen Information:

This easy carrot mug cake is gluten-free, nut-free, soy-free, and oat-free. Using plant-based butter makes it dairy-free.

Flour Blends Tested:

  1. King Arthur Measure for Measure —This blend works really well in my recipes. I don’t have to let the flour blend rest in the batter.
  2. Pillsbury Gluten Free Flour —This blend also works well in all of my mug cake recipes.
  3. DIY Gluten Free Flour Blend – My custom flour blend also works well in my mug cake recipes.

Ingredient Notes:

  • Gluten Free Flour Blend – I tested this mug cake with the two flour blends listed above. If your gluten free flour blend doesn’t contain xanthan gum or guar gum, please add 1/2 teaspoon.
  • Baking Powder – Use aluminum-free baking powder.
  • Butter – I recommend unsalted butter
  • Non-Dairy Milk – I used almond milk, but other dairy-free milk will work. I do not recommend canned coconut milk.
  • Nuts and Raisins – these are both optional.

Step-By-Step Photos and Directions:

Photos of steps 1 and 2 of making the carrot mug cake.

Step 1: Add the dry ingredients into a mug. Mix well. Shred the carrot. You need 2 tablespoons worth.

Step 2: In a small bowl, add the butter and cook for 30 seconds to melt it. Whisk in the rest of the ingredients. Add shredded carrot.

👀 Sandi Says: I highly recommend mixing the wet ingredients in a separate bowl and pouring them into the mug. This makes sure your ingredients are completely mixed.

Step 3: Add the raisins and walnuts and mix well. Be sure to scrape along the bottom edges so no flour pockets are missed.

Step 4: This is what your cake batter will look like. You want the batter to come no higher than 2/3 of the mug, or it can overflow like a volcano!

Step 5: Microwave the carrot cake for 90 seconds. It rises while cooking and sinks a little after you open the microwave door. This is normal.

Cooking time will vary slightly depending on the mug shape and depth. If the top is done, it will feel firm. The mug cake will pull away from the sides when it is cooked.

Step 6: Allow the gluten free carrot mug cake to cool completely. If you are frosting the cake, you can make the frosting. (See below for the recipe.)

You can pipe frosting on or spread over the top like in the other photos.

Try these yummy topping ideas:

You can add several fun toppings to this carrot cake. You can also dump the mug cake onto a plate and top it. I showed photos of both ways.

  • Frosting! Make a small batch of frosting by mixing two tablespoons of soft butter with 3-4 tablespoons of powdered sugar. Add one teaspoon of water if needed to make it softer.
  • Make the icing by mixing three tablespoons of powdered sugar with two teaspoons of water and drizzle over the mug cake.
  • Chopped pecans or your favorite nuts.
  • Caramel sauce
  • Vanilla ice cream or whipped cream

The possibilities are endless! You can make this cake fit exactly what you are craving. If you love the idea of making a cake in under 5 minutes, check out more of my delicious gluten free mug cake recipes!

Baking Directions:

A reader asked if this microwave cake can be baked in the oven, and yes, it can! You will need a tiny baking dish like a large ramekin.

  1. Mix up the cake batter and put it into a greased baking dish.
  2. Bake for 10-15 minutes at 350º F.
  3. You can check if it is done by inserting a toothpick into the middle. If the toothpick comes back clean, it is finished baking.

Frequently Asked Questions:

How big should the grated carrot shreds be?

You can use any size grater. I used a small grater, and in hindsight, I think the larger carrot shreds would have been better. The flavor is the same, but the thicker shreds appear more in every bite.

How do you know when a mug cake is done? 

The best way to check if a mug cake is done is by touching it. Due to the microwave’s cooking process, the standard toothpick test isn’t as reliable.

If your mug cake has a little bounce back when you touch it or isn’t sticky, you’re good to go. 

How long does it take to make a microwave mug cake

The answer is it varies. Depending on the power of your microwave, the size of your mug, and other variables, the cooking time can vary by almost a minute.

Just make sure to stop and check on your cake as you heat it up. That way, you don’t over-bake it. Or if you finish the time and it is still a bit sticky, place it back in the microwave and cook a little longer. 

This recipe is easy and is so delicious. The first time I made this I drizzled with glaze. The second time I removed cake from mug and sprinkled with powder sugar! I love making the individual cake for so many reasons–first is the amount of flour etc.; no big cake to tempt eating; and with all the recipes.
