Add all of the wet ingredients to a 2 cup glass measuring cup (or small bowl) and mix well using a fork.
Add in the dry ingredients and mix until the batter is smooth and there are no lumps. Fold in the chocolate chips.
Pour the mixture into a medium-sized mug and smooth out the top. Add additional chocolate chips on top, if desired. Microwave for 1-2 minutes. Mine was perfect at the 1.5 minute mark!
Let it cool for 1-2 minutes. Top with a scoop of dairy free icecream or whipped cream, if desired. Enjoy!
Notes
Expert Tips
This gooey gluten-free chocolate mug cake will be HOT when it comes out of the microwave! Let it cool for a minute or two before digging in. You can mix all of the ingredients directly in the mug, but I find it easier to mix separately first and then pour it into the mug.
Top with vanilla ice cream or whipped cream, if desired! You can also top with a spoonful of peanut butter, other nut butter, fresh berries, a dusting of cocoa powder or ground cinnamon, and more! Or Serve with a glass of your favorite dairy-free milk like almond milk or coconut milk.
I have not tested this recipe with any other gluten-free flour alternatives. You could try using Bob’s Red Mill gluten-free all-purpose flour. Let me know if you do and how it turns out in the comment below.
To make this vegan, you can swap the egg for applesauce. I haven't tried it with a flax egg, but if you do, please let us know how it goes in the comments below! You can use 1.5 tbsp applesauce in place of the egg!
