Step‑by‑Step Instructions for Indulging in a Molten Double Chocolate Mug Cake in 3 Minutes
Step 1: Mix Dry Ingredients
In a 12- to 14-ounce ceramic mug, combine granulated sugar, unsweetened cocoa powder, all-purpose flour, baking powder, and a pinch of salt. Use a fork to whisk these dry ingredients together until they are thoroughly blended. This ensures an even distribution of flavors, setting the foundation for your indulgent molten double chocolate mug cake.
Step 2: Incorporate Wet Ingredients
Add sour cream, a large egg yolk, chocolate chips, and a splash of water to the dry mixture in your mug. Stir vigorously with your fork until everything is smoothly combined, and there are no lumps. This forms a thick, luscious batter that promises a gooey center once your cake is done cooking.
Step 3: Microwave
Place your mug in the microwave and cook on high for 1 to 1½ minutes. Keep a close eye on your cake as it cooks—watch for it to rise and look slightly wobbly in the center. The microwave time may vary depending on wattage, but avoid overcooking to keep that unforgettable molten chocolate goodness intact.
Step 4: Cool and Serve
Once cooked, carefully remove the mug from the microwave (it will be hot!). Allow the molten double chocolate mug cake to cool for about 1 minute. This cooling time is essential for the cake to set slightly, making it perfect for topping with a scoop of vanilla ice cream or a dollop of whipped cream for an extra indulgent bite.

Molten Double Chocolate Mug Cake Recipe FAQs
Which ingredients should I use for the best chocolate flavor?
I absolutely recommend using high-quality unsweetened cocoa powder for a rich chocolate flavor. If you’d like to experiment, feel free to swap it with Dutch-processed cocoa, which gives a slightly different taste and might be a fun twist in your mug cake adventures!
How should I store leftover mug cake?
Store any leftover molten double chocolate mug cake in an airtight container in the fridge for up to 3 days. This helps maintain its luscious flavor, but keep in mind that the gooey center may lose some of its charm over time. To enjoy it warm, just pop it in the microwave for about 10-15 seconds to bring back that comfort!
Can I freeze the mug cake?
Certainly! To freeze, wrap individual portions tightly in plastic wrap and then in foil to prevent freezer burn. You can store them for up to 2 months. When you’re ready to indulge, simply thaw in the fridge overnight, and reheat in the microwave for 10-15 seconds to restore that heavenly molten center.
What if my mug cake overflows in the microwave?
No worries! If your cake overflows, it typically means your mug is too small. I suggest using a 12- to 14-ounce ceramic mug next time to allow room for rising. If it overflows, just clean up your microwave quickly, and enjoy the bottom of the cake; it tends to have a delightful fudgy edge!
Is this recipe safe for those with gluten allergies?
Absolutely! You can make a gluten-free version by substituting all-purpose flour with a gluten-free flour blend. Just ensure that all your baking ingredients, including baking powder, are certified gluten-free. Enjoy this indulgence without worries; chocolate is meant to be shared joyously!
Are there any toppings or variations I can try?
The more the merrier when it comes to toppings! You can sprinkle rainbow sprinkles on top for a delightful look or add fresh berries for a fruity twist. A dollop of whipped cream or vanilla ice cream will elevate your molten double chocolate mug cake into a decadent dessert that’ll impress anyone!
