Hot Chocolate Mug Cake
This hot chocolate mug cake is rich, gooey, and ready in just 5 minutes - with a jumbo marshmallow hidden in the center that melts into a lava-style middle! It’s made with hot cocoa mix, chocolate chips, and marshmallows for the perfect quick treat.
Ingredients
- 1 packet hot cocoa mix (about ¼ cup)
- ¼ cup all-purpose flour
- ¼ cup milk
- 2 tablespoon vegetable oil
- 2 tablespoon milk chocolate chips
- 1 jumbo marshmallow
- mini marshmallows
Instructions
- In a microwave-safe 12–14 oz mug, whisk together hot cocoa mix + flour. Stir in milk + oil until smooth.
- Fold in chocolate chips. Press 1 jumbo marshmallow into the center until just covered. Sprinkle mini marshmallows on top (don’t stir).
- Microwave 50–60 seconds, until the top is set but the center is still soft (start at 45–50 seconds for high-watt microwaves; add 10–15 seconds if needed).
- Rest 1–2 minutes, then serve warm (add chocolate syrup, whipped cream, or ice cream if desired).
Notes
- Hot cocoa mix is required (not cocoa powder). The added sugar and milk powder are essential for the correct flavor and texture.
- Use a 12–14 oz microwave-safe mug. The batter should fill no more than halfway to prevent overflow.
- For the lava center, use 1 jumbo marshmallow and press it fully into the center until just covered. Mini marshmallows melt too quickly for the middle.
- Microwave only until the top is set. The center should still feel soft; overcooking will dry out the cake and melt away the lava center.
- Microwave wattage matters. Start at 45–50 seconds for high-watt microwaves (1200W) and add time in 10–15 second increments if needed.
- Rest for 1–2 minutes before eating so the cake finishes setting while staying gooey inside.
- Best eaten immediately. Mug cakes become rubbery as they cool and do not store well.
