🍯 Why This Recipe Works

There are no eggs. I love how this is a no egg mug cake recipe, so even if it comes out a little underbaked- it's safe to eat. Perfect for pregnant women or even those with egg allergies! For more eggless recipes check out our Eggless Banana Bread and Chocolate Chip Cookies Without Eggs.
It's rich. I love to make this brownie when I'm looking for a rich and indulgent treat. I've even figured out which mug in the cupboard has enough space to hold the brownie plus a scoop of ice cream.
It's frugal. Made with basic pantry staple ingredients, you can imagine that this recipe is pretty cheap to make. We estimate that it costs about 50 cents.

🥘 Ingredients

Ingredient Notes:

Flour- You will need some all purpose flour for the gluten structure and base of this recipe.

Cocoa powder- Use some baking cocoa to give this brownie a rich chocolatey taste in every bite.

Baking powder- To help the mug brownie rise as it bakes, you'll need some baking powder.

Coconut Oil- To give the cake some necessary fats, use coconut oil (butter or shortening will work fine too).

Milk- This is needed to hydrate the mix and add a richer taste. Use your favorite non-dairy milk of choice.

Dairy free chocolate chips- I prefer to use enjoy life brand chocolate chips, but you can use your favorite nondairy chocolate chips.

For specific ingredients and measurements, please see the recipe card below.

🧾 Substitutions

Different oil. If you don't want to use coconut oil you can use canola or vegetable oil instead. I wouldn't recommend using olive oil as that changes the flavor of this brownie a bit and can be offputting.

Different milk. Switch out the milk for coffee creamer or cold coffee and these brownies are amazing. Although I've made them with plain water once or twice and they turned out fine (not as wonderful but it got the job done).

📖 Variations

Adjust sweetness. If you want your vegan chocolate mug cake sweeter you can add in up to another tablespoon of sugar (I think that makes it too sweet) but to each their own.

Adjust richness. You can also reduce the cocoa powder by ½ tablespoon if you want it a little less rich, or you can add in a teaspoon of instant coffee for an even richer experience.

🍴 Recipe Tips

Mixing Tip: When preparing the brownie batter in a mug, rotate the mug to avoid buildup on the sides. Ensure thorough mixing to prevent unmixed baking powder.
Coconut Oil Preparation: Use completely melted coconut oil to prevent separation in the batter, ensuring a smooth texture.

⏲️ Oven Method

Can I make vegan mug brownies in the oven? Absolutely! Just make sure that you have an oven-safe mug and that you place it directly on a baking sheet. Bake in the oven at 350 degrees F for 10 minutes and then test for doneness.

💭 Recipe FAQs

How do you know when a mug cake is done?

Unlike normal cakes that are dry throughout and can be tested with a toothpick, mug cakes should have a slightly wet appearance in the center. If your mug cake doesn't feel sticky or looks dry then there's a chance that you overcooked it.

Why are mug cakes chewy?

If your brownie is rubbery or chewy that's a sign that it was overcooked. While still flavorful it doesn't have the same texture that you'd expect or want from a mug cake.

Can you make mug cakes in advance?

You can prepare the dry ingredients in advance and simply keep them in a small bag or container until you're ready to eat. This makes it great for a faster process when it comes to making these vegan brownies.
