2 tablespoons cocoa powder
2 tablespoons white sugar
¼ teaspoon baking powder
1 pinch salt
¼ cup plant-based milk (such as oat or soy)

1 tablespoon vegan chocolate chips (optional, but recommended)
vegan whipped cream or vanilla ice cream for serving (optional)

Instructions

Mix the dry ingredients: In a microwave-safe mug (10 to 12 oz capacity), whisk together the flour, cocoa powder, sugar, baking powder, and salt.
Add the wet ingredients: Stir in the plant-based milk, oil (or melted butter), and vanilla. Mix until just combined, don’t overmix. Stir in the chocolate chips, if using. Sprinkle a few extra on top for extra gooeyness.
Microwave: Cook on high for 1 minute 15 seconds to 1 minute 30 seconds, or until the top looks mostly set but still slightly moist. Every microwave is different, so start checking at the 1-minute mark. It's better to slightly undercook (think gooey fudgy spots) than to overcook.
Let it cool: Allow the mug cake to cool for 1–2 minutes. Top with ice cream, whipped cream, or enjoy as-is.

Notes

Oil-Free Option: Use 1 tablespoon nut or seed butter, or unsweetened applesauce, in place of oil. The cake will be a bit denser but still delicious.

Gluten-Free Option: Use a 1:1 gluten-free all-purpose flour blend in place of regular flour.

High-Protein Version: Use 2 tablespoons flour, 3 tablespoons chocolate protein powder, 1 tablespoon cocoa powder, and just 1 tablespoon sugar (or less, depending on the sweetness of your protein powder). Keep everything else the same. The result is slightly denser but super fudgy. A perfect protein-packed treat.

Sugar Swap Ideas: Use coconut sugar, brown sugar, or maple syrup (reduce the milk slightly if using a liquid sweetener). Granulated monk fruit or erythritol-based blends also work, start with 1 tablespoon and adjust to taste.

Topping & Add-In Ideas

Take your mug cake to the next level with these delicious mix-ins and toppings:

Nutty & gooey

A spoonful of vegan Nutella, swirled in before cooking
A dollop of peanut butter, almond butter, or tahini in the center gooey core
Chopped toasted pecans, walnuts, or hazelnuts for crunch
A big square of chocolate pushed into the center of the batter for a lava core

Fruity

A few frozen raspberries or cherries folded into the batter
Swirl in a spoonful of berry jam for a fruit twist
Top with fresh strawberries, raspberries, blueberries, or sliced banana after cooking

Extra indulgent

A handful of mini vegan marshmallows for a s’mores-style cake
Crushed graham crackers, Oreos, or chocolate sandwich cookies on top
A drizzle of melted chocolate, caramel sauce, or maple syrup just before serving
Add ¼ teaspoon instant espresso powder to the dry ingredients for a mocha flavor boost

Cool & creamy

Scoop of vegan vanilla or chocolate ice cream
Dollop of coconut whipped cream
Sprinkle of flaky salt to bring out the chocolate
A light dusting of powdered sugar for a bakery-style finish
