Ingredients

  • 3 tablespoons gluten-free flour blend (27g)
  • 3 tablespoons granulated sugar (37.5g)
  • 3 tablespoons cocoa powder (22g)
  • 1/4 teaspoon baking soda
  • 1/8 teaspoon salt
  • 2 tablespoons vegetable oil (or other neutral-tasting oil)
  • 3 tablespoons unsweetened almond milk (50g)
  • 1/2 teaspoon vanilla extract

Instructions

  • Whisk the gluten-free flour, granulated sugar, cocoa powder, baking soda, and salt together in a glass mug or ramekin.
  • Add the oil, almond milk, and 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

  • My microwave is 1000 watts and I cooked my gluten-free mug cake for about 65-70 seconds. Depending on the power on your microwave, you may need more or less time than I did. Microwave the mug cake for one minute and see if it’s done cooking. If not, keep microwaving in 10-15 second increments until it’s cooked through. 
  • If you overcook your mug cake, it will be really rubbery. 
  • I like to mix all of my ingredients in my mug, but you can also mix it together in a small bowl first if you prefer. You can make sure the batter gets thoroughly mixed together this way.
  • This recipe was tested with Bob’s Red Mill 1-to-1 Gluten-Free Baking Flour (in the blue bag). I cannot guarantee that other gluten-free flour blends or almond flour will work because I have not tested them myself. 
  • Vegan option: This recipe is vegan as long as you use granulated sugar that is vegan. 
  • Dairy-free option: As written, this recipe is already dairy-free. If you are not dairy-free, you can use cow’s milk if you prefer.
