Instructions

Whisk 3 tablespoons (27 g) gluten-free flour blend, 3 tablespoons (38 g) granulated sugar, 3 tablespoons (15 g) cocoa powder, ¼ teaspoon baking soda, and ⅛ teaspoon salt together in a glass mug or ramekin.
Add 2 tablespoons (28 g) vegetable oil, 3 tablespoons (50 g) unsweetened almond milk, and ½ teaspoon vanilla extract to the dry ingredients. Stir to combine.
Microwave for 60-90 seconds, until the top of the cake no longer looks shiny and a toothpick inserted into the center comes out clean. Do not overbake!
Let cool for a few minutes before serving. Top with chocolate frosting and sprinkles if you’d like!

Notes

Gluten-Free Flour: I tested this with Bob's Red Mill 1-to-1 Gluten-Free Baking Flour (blue bag). I cannot guarantee other gluten-free flour blends will work as I have not tested them.
Microwave Wattage: My microwave is 1000 watts and I cooked this for about 65-70 seconds. If yours is more powerful, start checking at 45 seconds. If less powerful, you may need the full 90 seconds.
Make Fresh: Best eaten immediately. The texture becomes dry and rubbery as it cools. Since it only takes 3 minutes to make, mix up a fresh one when you need it.
Dairy-Free/Vegan: This recipe is already dairy-free as written. To make it vegan, use a granulated sugar that is vegan certified.
