Ingredient notes:
- 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?
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.
Step 2: Mix the wet ingredients with the dry ingredients.
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.

I am so glad you and your granddaughters had fun making this recipe :-).
Tara
Is it 90 seconds in the microwave or 3 minutes? I see both written here and that makes a big difference!
Sandi Gaertner
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.
