    It is all about the quick chocolate fix here. I love brownies, but I am often lazy when it comes to making them. I have a fantastic gluten free brownie recipe on my blog...but often, I am busy creating other recipes.

    This is also a great recipe for college students who want a fun treat to make in their dorm room. Mug cakes are easy because you only need a microwave and a coffee mug! This easy gluten free vanilla mug cake is another great microwave cake recipe!

    I love making this recipe when it is too hot to use the oven in the summer. It is nice to enjoy cake without heating up the house!!

    Why This Recipe is Great:

    1. If you are like me and crave chocolate but don't want to bake something, this easy brownie mug cake recipe is for you!
    2. This microwave brownie is full of rich chocolate flavor, and you can vary it with so many mix-ins.
    3. This recipe is perfect for those with food allergies. It is not only gluten free but dairy-free and egg-free too!
    4. It makes one mug brownie, so double the recipe if you think a family member will try to steal some from you :-). This also makes a great Valentine's Day dessert!

    This was perfect for dessert tonight with some whipped cream on top. I subbed the water with coffee. It was delicious."

    Ingredient notes:

    Photos of the gluten free mug brownie ingredients.
    • Gluten Free Flour Blend - I have tested this recipe with King Arthur Measure for Measure GF, my DIY Gluten Free Flour Blend, 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.
    • Xanthan Gum - If your gluten free flour blend doesn’t contain xanthan gum or guar gum, please add ¼ teaspoon.
    • Cocoa Powder - Many great brands of cocoa powder are gluten free. Just be sure to check the label.
    • Chocolate Chips - Use any flavor of chocolate chips or even chocolate chunks!
    • Coconut Oil - I love the flavor coconut oil adds to this gluten free microwave brownie, but you can use any light oil.
    • Vanilla Extract - Use pure vanilla extract or imitation. It won't matter in this recipe.

    Substitutions:

    • Make it sugar-free! Swap the sugar for Monk Fruit Sweetener to make this gluten-free mug brownie sugar-free. It should be a 1:1 swap.
    • Make this mug brownie recipe gum-free (no xanthan or guar gum) using my DIY Gluten Free Flour Blend.
    • For no off taste from the coconut oil, use Canola Oil.

    How To Make A Mug Brownie:

    Are you ready to give this delicious recipe a try?

    The mug brownie dry ingredients in a glass bowl.

    Step 1: Add the dry ingredients to the mug and mix well. Note that you can mix all of this up in your mug.

    I find that the dry ingredients don't get mixed, so when you eat the cake, some flour is stuck around the edges. I mix the ingredients in a bowl and then add them to my mug to fix this.

    This is what your dry ingredients will look like mixed up. Add in the chocolate chips.

    The wet and dry mug brownie ingredients ready to mix.

    Step 2: Mix the wet ingredients with the dry ingredients.

    The brownie batter in the mug.

    Step 3: Put the mug into your microwave and cook for 90 seconds on high. Actual cooking time will depend on the size of your mug, its depth, and how wide the base is. You may need to cook it longer using a tall mug with a narrow base.

    You will know your gluten free mug brownie is slightly firm to the touch.

    Top with vanilla ice cream, hot fudge, or some of the following mix-ins and toppings ideas.

    Fun Mix-In Ideas:

    • Use different flavors of chocolate chips, like white chocolate and salted caramel chocolate chips.
    • Add in walnuts or pecans.
    • Why not add some M&Ms? It will add some fun color!
    • Put a tablespoon of peanut butter in the middle of the cake batter for a gooey peanut butter middle.

    Recipe FAQ:

    What brands of cocoa powder are gluten free?

    I love to use Rodelle, Anthony's, and Ghirardelli brands of gluten free cocoa powder.

    Why did the mug cake turn out gooey?

    Usually, if your cake turns out gooey, it didn't cook long enough in the microwave. Cooking time will vary depending on your mug size and how wide the mug base is.

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

    Your mug cake cooking time will vary depending on the size of your mug. The cake will be firm to the touch when it is done cooking.

    How long will this brownie keep fresh?

    These mug brownies will keep for up to 3 days in an air-tight container or up to 4 months in the freezer.

      Is it 90 seconds in the microwave or 3 minutes? I see both written here and that makes a big difference!

        I looked through the entire post and it says both in the step by step directions and recipe card to cook the cake for 90 seconds. The title is 3 minutes because it includes the time to put the ingredients together to make it.

      this was such a yummy treat. Instead of water I used leftover cold coffee. Topped with some coconut whipped topping, it was a decadent dessert, and so very easy.
