Craving a rich, chocolatey dessert that’s ready in minutes? This Molten Lava Mug Cake delivers a warm, gooey center with minimal effort, perfect for satisfying your sweet tooth without baking a full cake.

Ingredients

• 4 tbsp All-purpose flour
• 2 tbsp Unsweetened cocoa powder (Dutch-processed or regular)
• 1/4 tsp Baking powder
• 1 pinch Salt
• 3 tbsp Granulated sugar
• 3 tbsp Milk (any kind: dairy or plant-based)
• 2 tbsp Vegetable oil (or melted butter)
• 1/4 tsp Vanilla extract
• 2 tbsp Chocolate chips (or small piece of chocolate bar for molten center)
• 1 tsp Espresso powder (optional – enhances chocolate flavor)

Instructions

1. Step 1: Prepare a microwave-safe mug by lightly greasing the inside or using a non-stick spray to prevent sticking.
2. Step 2: In a small bowl, whisk together the flour, cocoa powder, baking powder, salt, granulated sugar, and espresso powder if using.
3. Step 3: Add the milk, vegetable oil, and vanilla extract to the dry ingredients. Stir until smooth and fully combined.
4. Step 4: Pour about half of the batter into the prepared mug.
5. Step 5: Place the chocolate chips or a small piece of chocolate bar in the center of the batter in the mug.
6. Step 6: Pour the remaining batter over the chocolate to cover it completely.
7. Step 7: Microwave on high for 70 to 90 seconds. Cooking times may vary based on your microwave’s power, so watch carefully to avoid overcooking.
8. Step 8: Let the mug cake rest for 1 to 2 minutes to set and allow the center to become gooey.
9. Step 9: Enjoy your molten lava mug cake straight from the mug for a quick and indulgent treat.

Tips & Variations

• For an extra fudgy center, use a small piece of your favorite dark chocolate instead of chocolate chips.
• Try adding a pinch of cinnamon or a dash of chili powder to the batter for a spicy twist.
• Swap vegetable oil for melted coconut oil for a subtle tropical flavor.
• If you don’t have espresso powder, a tiny splash of coffee enhances the chocolate taste but isn’t necessary.

Storage

This mug cake is best enjoyed immediately for the gooey center experience. If you have leftovers, cover and refrigerate them for up to 1 day. Reheat gently in the microwave for 20-30 seconds, but the molten center may be less gooey after reheating.

How to Serve

Serve this delicious recipe with your favorite sides.

FAQs

Can I use gluten-free flour for this recipe?

Ingredients

Scale 1x2x3x

Dry Ingredients

• 4 tbsp All-purpose flour
• 2 tbsp Unsweetened cocoa powder (Dutch-processed or regular)
• 1/4 tsp Baking powder
• 1 pinch Salt
• 3 tbsp Granulated sugar
• 1 tsp Espresso powder (Optional – enhances chocolate flavor)

Wet Ingredients

• 3 tbsp Milk (Any kind: dairy or plant-based)
• 2 tbsp Vegetable oil (Or melted butter)
• 1/4 tsp Vanilla extract

Filling

• 2 tbsp Chocolate chips (Or small piece of chocolate bar for molten center)

Instructions

1. Prepare Equipment: Use a microwave-safe mug that can hold at least 12 ounces to avoid overflow during cooking.
2. Mix Dry Ingredients: In the mug, combine 4 tablespoons all-purpose flour, 2 tablespoons unsweetened cocoa powder, 1/4 teaspoon baking powder, a pinch of salt, 3 tablespoons granulated sugar, and 1 teaspoon espresso powder if using. Stir thoroughly to evenly distribute all dry ingredients.
3. Add Wet Ingredients: Add 3 tablespoons milk, 2 tablespoons vegetable oil, and 1/4 teaspoon vanilla extract to the dry mixture. Stir until you achieve a smooth batter without lumps.
4. Add Chocolate Center: Gently press 2 tablespoons of chocolate chips or a small piece of chocolate bar into the center of the batter in the mug, ensuring it is slightly submerged to create the molten core.
5. Cook in Microwave: Microwave the mug cake on high power for 70 to 90 seconds. Start with 70 seconds and check—cooking time may vary based on microwave wattage. The edges should be set while the center remains soft and gooey.
6. Let Rest: Allow the cake to rest for about 1 minute to let it finish cooking from residual heat and to cool slightly for safe eating.
7. Serve and Enjoy: Enjoy the molten lava mug cake directly from the mug, optionally topped with whipped cream, ice cream, or a dusting of powdered sugar for an added treat.

Notes

• Microwave ovens vary; adjust cooking time accordingly to avoid overcooking or undercooking.
• For a richer flavor, use melted butter instead of vegetable oil.
• Espresso powder is optional but intensifies the chocolate taste without imparting a coffee flavor.
• Make sure to leave room in the mug to prevent overflow while microwaving.
• Consume immediately for the best molten lava effect.
