Gluten Free Mug Cake - Danielle Walker

Three ingredient mug cakes that can be made in three minutes? Why would I ever make any other dessert?! I’m kidding of course…but only sort of. Because there’s just no beating the convenience and decadence of making yourself a warm cake just because it’s Wednesday, you had a hard day, a great day, or simply because you just feel like one! Those of you who follow me closely know I’ve been coming up with several different riffs on the mug cake, but this one — my chocolate Gluten Free Mug Cake — is one of my all-time favorites.

3 ingredient mug cake 

One reason I love this recipe so much? It literally only uses things I always, without fail, have on hand in my fridge and pantry. The genius of it is in using a store-bought grain and gluten-free cake mix as the base. I really like using either Bob’s Red Mill  or Simple Mills grain-free baking mixes for this recipe. From there, you add an egg, avocado oil, and water and you’re done! You can then either pop it into the microwave (for a whopping 90 seconds) or into a 350-degree oven for 16 minutes. Then a warm, rich, chocolate gluten-free cake in the perfect serving size is all yours.

Gooey chocolate mug cake 

Now, I can’t force you to, but if you’re like me and you just love a chocolate cake that’s a little bit gooey, I highly recommend adding chocolate chips to your mug before baking. This will give you those rich, warm swirls of pure melted chocolate in every bite.

Dairy-free icing

This cake is ready to eat fresh out of the oven or microwave, but if you want to you can add a tablespoon of non-dairy frosting to the top. And if you want to go all out, top that frosting with some dye-free sprinkles! My preferred dairy-free frosting is by Miss Jones. I love their vanilla version on top of this warm chocolate gluten-free mug cake.

  1. Renee Romero says:

    Can you make this with chocolate protein powder?

    • Danielle says:

      Hi Renee! I don’t recommend subbing the grain-free mix with protein powder. You can potentially add the protein powder to the mix but I can’t guarantee that it won’t affect the final texture and rise of the cake. Let us know if you give it a try with the added chocolate protein – another reader with the same question will find your feedback so helpful!

  2. Judith Cudworth says:

    Have you ever tried this with a flax egg? Will it work? I’m allergic to eggs.

    • Danielle says:

      Hi Judith, the recipe has only been tested with an egg, but if you try it with a flax egg, please let us know how it turns out!

  3. Jacqi B says:

    This recipe is so easy and delish! Thank you so much for creating it! This summer we have had so many birthdays and celebrations that all involve cake and now I can easily make this for myself as an alternative. So good!!!

    • Danielle says:

      So glad you love it, Jacqui! It’s a game changer to have a recipe so easy and accessible as an alternative!

    Can this be made in the regular oven? I don’t have a microwave!

    Has anyone tried it in an air fryer?
