Why It Works Every Time

The beauty of the Double Chocolate Mint Mug Cake lies in its simplicity and speed. The combination of bittersweet chocolate and cocoa powder creates a deep chocolate flavor, while the peppermint extract adds a refreshing twist that transports you to a cozy café. Using coconut oil gives the cake a moist texture, and the almond milk keeps it dairy-free. Best of all, the microwave does all the hard work, delivering a perfectly risen cake in under two minutes.
Ingredients at a Glance
- 11-ounce square bittersweet or dark chocolate, broken into pieces, or 2 tablespoons semi-sweet or dark chocolate chips (Ghirardelli 60% baking chocolate recommended)
- 2 teaspoons coconut oil (can substitute vegetable oil)
- 3 tablespoons all-purpose flour or white whole wheat flour
- 1 tablespoon cocoa powder
- 1/4 teaspoon baking powder
- 2 tablespoons unsweetened almond milk
- 1 tablespoon pure maple syrup
- 1/4 teaspoon instant espresso powder (optional)
- 1/2 teaspoon pure vanilla extract (optional)
- 1/16 teaspoon or about 6 drops peppermint extract
- Coconut whipped cream (or dairy whipped cream for non-vegan version)
- Mini chocolate chips (for garnish)
- Fresh mint (for garnish)
Setup & Equipment
- Mug or microwave-safe bowl: Choose a large enough container to allow the cake to rise without overflowing.
- Microwave: Essential for quick cooking.
- Measuring spoons: For accurate ingredient measurements.
- Mixing spoon or whisk: To combine the ingredients smoothly.
- Optional: Microwave-safe plate (to catch spills if any occur).
Double Chocolate Mint Mug Cake in Steps

Step 1: Melt the Chocolate
In your mug or bowl, add the broken pieces of bittersweet chocolate or chocolate chips along with the coconut oil. Microwave in 30-second intervals, stirring in between, until fully melted and smooth.
Step 2: Mix Dry Ingredients
In a separate small bowl, whisk together the all-purpose flour, cocoa powder, baking powder, and instant espresso powder (if using). This ensures an even distribution of dry ingredients.
Step 3: Combine Wet Ingredients
Once the chocolate mixture has cooled slightly, add the almond milk, pure maple syrup, vanilla extract (if using), and peppermint extract. Stir until well combined.
Step 4: Incorporate Dry Ingredients
Gradually add the dry ingredient mixture into the wet ingredients, stirring gently until just combined. Be careful not to overmix; a few lumps are perfectly fine.
Step 5: Add Extra Chocolate
Fold in mini chocolate chips if desired for an extra chocolatey experience.
Step 6: Microwave
Place the mug in the microwave and cook on high for 1 minute and 30 seconds. Keep an eye on it as microwaves can vary; you want the cake to be set but still slightly gooey in the center.
Step 7: Let It Cool
Allow the mug cake to cool for a minute before digging in. This helps the cake set and makes it easier to enjoy.
Step 8: Top It Off
Finish your Double Chocolate Mint Mug Cake with a generous dollop of coconut whipped cream or dairy whipped cream, a sprinkle of mini chocolate chips, and a few fresh mint leaves for an elegant touch.
Variations by Season

- Winter: Add a pinch of cinnamon or nutmeg for a warm holiday flavor.
- Spring: Top with fresh berries for a fruity contrast to the chocolate and mint.
- Summer: Mix in some crushed cookies for a fun texture and flavor boost.
- Fall: Incorporate pumpkin spice to bring in those cozy autumn vibes.
Pitfalls & How to Prevent Them
- Overcooking: To avoid a dry mug cake, start with 1 minute and check for doneness. If it isn’t set, add additional time in 10-second increments.
- Spilling: Ensure your mug is large enough to accommodate the rising cake, or place a microwave-safe plate underneath to catch any spills.
- Uneven texture: Stir the batter gently and avoid overmixing to maintain a light, fluffy texture.
- Flavor imbalance: Measure your extracts carefully, especially the peppermint, as it can easily overpower the chocolate flavor.
Make Ahead Like a Pro
The Double Chocolate Mint Mug Cake is best made fresh, but if you want to prep in advance, you can measure out the dry ingredients and store them in an airtight container. When you’re ready to indulge, simply add the wet ingredients and microwave as directed. This way, you can have a warm treat ready in minutes with minimal effort.
