| Ingredient | Amount | Notes |
|---|---|---|
| All-purpose flour | 4 tbsp | Lightly spooned and leveled |
| Granulated sugar | 3 tbsp | Adjust for sweetness |
| Cocoa powder | 1 tbsp | Use unsweetened for balance |
| Espresso powder | 1 tsp | Instant coffee works if needed |
| Baking powder | 1/4 tsp | For lift |
| Salt | Pinch | Balances flavors |
| Milk | 3 tbsp | Any milk, dairy or plant-based |
| Neutral oil | 1½ tbsp | Keeps it moist |
| Vanilla extract | 1/2 tsp | Adds warmth |

Step-by-Step Directions
Follow these simple steps for a café-worthy dessert.
- Mix dry ingredients.
In a microwave-safe mug, whisk flour, sugar, cocoa, espresso powder, baking powder, and salt until well combined. - Add wet ingredients.
Pour in milk, oil, and vanilla. Stir until smooth, scraping down the sides and bottom. - Swirl it up.
Sprinkle chocolate chips (if using) on top, then drag a spoon gently through the batter to create mocha swirls. - Microwave.
Heat on high for 1 minute 30 seconds. If the center is still wet, cook in 10-second intervals until just set. - Cool briefly.
Let rest for a minute—this keeps the texture tender and moist.
Pro Tip: Don’t overcook; the cake will continue to set as it cools.
How to Serve
- Enjoy straight from the mug for a warm, gooey treat.
- Drizzle with melted chocolate, caramel, or a splash of cream.
- Top with whipped cream and a sprinkle of cocoa for café vibes.
- Pair with a fresh espresso shot or hot milk for a cozy combo.
Expert Tips for Success
- Use good-quality espresso powder for the best flavor.
- For a richer taste, substitute half the milk with brewed coffee (cooled).
- Want extra indulgence? Add a teaspoon of Nutella or peanut butter before microwaving.
- If you like it less sweet, reduce the sugar slightly.
- For a vegan option, use plant milk and dairy-free chocolate chips.
Store leftovers (if you somehow resist finishing!) in the fridge, covered, for up to a day. Reheat gently before serving.
Common Questions
Can I make this without espresso powder?
Yes! Use instant coffee granules or omit for a simple chocolate mug cake.
How can I make the swirl stand out?
Drop a teaspoon of chocolate syrup or thick coffee paste on top of the batter, then swirl lightly with a fork.
Can I bake it instead of microwaving?
Absolutely. Pour into an oven-safe ramekin and bake at 350°F (175°C) for 12–14 minutes.
How do I avoid a dry cake?
Stick to the recommended cook time, and stop as soon as the center looks set but still soft.
Can I add frosting?
Sure! A dollop of whipped cream, buttercream, or coffee glaze makes it extra special.
