Ingredients

Ingredients	Quantity
All-purpose flour	4 tbsp
Unsweetened cocoa powder	2 tbsp
Granulated sugar	2 tbsp
Baking powder	1/4 tsp
Salt	A pinch
Milk	3 tbsp
Vegetable oil	1 tbsp
Vanilla extract	1/4 tsp
Mini marshmallows	Handful
Chocolate chips	1 tbsp
Optional toppings (whipped cream, chocolate syrup, sprinkles)	As desired

Ingredient Notes:

Use high-quality cocoa powder for a rich, chocolatey flavor.
Swap regular milk with almond or oat milk for a dairy-free version.
Feel free to add a pinch of instant coffee powder to enhance the chocolate flavor.

Equipment Needed

Microwave-safe mug (12 oz or larger)
Measuring spoons and cups
Whisk or small fork
Microwave

Why the Mug Matters:
Using a microwave-safe mug that’s at least 12 oz ensures the cake rises without overflowing during cooking.

Step-by-Step Instructions

Step 1: Mix the Dry Ingredients

In your microwave-safe mug, combine the flour, cocoa powder, sugar, baking powder, and a pinch of salt. Stir them together with a fork or small whisk until evenly mixed.

Step 2: Add the Wet Ingredients

Pour in the milk, vegetable oil, and vanilla extract. Stir until you have a smooth batter with no lumps. Be sure to scrape the sides and bottom of the mug for even mixing.

Step 3: Add Chocolate Chips

Fold in the chocolate chips gently into the batter. These will create pockets of melty chocolate goodness.

Step 4: Microwave the Cake

Place the mug in the microwave and cook on high for 60-90 seconds. The cake should rise and look set on top but still moist. Avoid overcooking, as it can turn dry.

Step 5: Add Marshmallows

Remove the mug from the microwave (careful, it’s hot!). Add a handful of mini marshmallows on top and microwave for an additional 10 seconds until they puff up slightly.

Step 6: Garnish and Serve

Top with whipped cream, a drizzle of chocolate syrup, or a dusting of powdered sugar. Enjoy immediately with a spoon.

Tips and Variations

Avoid Overcooking: Start with 60 seconds and add increments of 10 seconds if needed. Overcooked mug cakes can become rubbery.
Make It Mocha: Add a teaspoon of instant coffee powder to the batter.
Dairy-Free Version: Use plant-based milk and skip the whipped cream topping.
Add a Surprise Center: Place a square of chocolate or a spoonful of Nutella in the center before microwaving for an extra gooey core.
Extra Fluffiness: Sift your dry ingredients for an airy texture.

Serving Suggestions

Presentation makes everything better, even a mug cake! Serve your Hot Cocoa Mug Cake with:

A generous dollop of whipped cream on top, dusted with cocoa powder.
A drizzle of caramel or chocolate syrup for added decadence.
Pair it with a hot cup of coffee or milk to balance the richness of the cake.
Add a sprinkle of festive sprinkles if serving during the holidays.

If serving guests, prepare multiple mug cakes and arrange them on a tray with small spoons for a cozy dessert spread.

Pairings

The rich, chocolatey flavor of the mug cake pairs beautifully with:

Hot Coffee or Espresso: The bitterness of coffee balances the sweetness of the cake.
Peppermint Hot Chocolate: For a double hot cocoa experience with a minty twist.
Vanilla Ice Cream: Serve a scoop on top for a warm-cold contrast.
Red Wine: A sweet red wine like Port complements the chocolate notes perfectly.

Storage and Reheating

While mug cakes are best enjoyed fresh, if you have leftovers:

Storage: Cover the mug with plastic wrap and store it in the refrigerator for up to 1 day.
Reheating: Microwave in 10-second intervals until warm. Avoid overheating.
Do Not Freeze: Mug cakes lose their texture when frozen.
