👩🏻🍳 Expert Tips
- Mix well. Rotate the mug as you stir so the batter doesn't stick to the sides and the baking powder is fully incorporated.
- Melt the oil. Make sure the coconut oil is fully melted so it blends smoothly into the batter.
- Oven option. Use an oven safe mug, place it on a baking sheet, and bake at 350°F for about 10 minutes, checking for doneness before serving.

❓ Vegan Mug Brownie FAQs
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.
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.
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.

📖 Recipe
Vegan Mug Brownie
Equipment
- Spoon or whisk
Ingredients
- 2 tablespoons all-purpose flour - ($0.02)
- 1 tablespoon granulated sugar - ($0.02)
- ¼ teaspoon baking powder - ($0.02)
- 1 pinch salt - ($0.01)
- 2 tablespoons cocoa powder - ($0.01)
- 1 tablespoon coconut oil, melted - ($0.18)
- 3 tablespoons dairy-free milk - ($0.06)
- ½ teaspoon vanilla extract - ($0.01)
- 1 tablespoon vegan chocolate chips - ($0.05)
Instructions
- Mix Dry Ingredients: In a microwave safe mug, add the flour, sugar, baking powder, salt, and cocoa powder. Stir well to combine, making sure to scrape along the sides and bottom.
- Add Wet Ingredients: Pour in the melted coconut oil, dairy free milk, and vanilla extract. Stir until mostly smooth. A few small lumps are fine.
- Add Chocolate Chips: Sprinkle the chocolate chips evenly over the top. Do not stir them in. More chips will create a gooier brownie, while fewer will result in a more cake like texture.
- Cook: Microwave for 40 to 60 seconds until just set. Alternatively, bake in an oven safe mug on a baking sheet at 350°F for about 10 minutes.
- Serve: Let cool briefly before enjoying.
Notes
- Sweetness. Add up to 1 tablespoon extra sugar if you prefer a sweeter brownie.
- Chocolate flavor. For deeper chocolate, add 1 teaspoon instant coffee. For a lighter taste, reduce cocoa powder by ½ tablespoon.
- Liquid options. Swap dairy free milk with coffee creamer, cold coffee, or water if needed.
- Doneness. The brownie is done when a toothpick comes out clean. A chewy or rubbery texture usually means it was overcooked due to microwave wattage.
- Make ahead. Mix the dry ingredients in advance and store in a small container or bag for quick mug brownies later.
