When you only have 15 minutes, you have to skip the oven entirely. The answer is the Microwave Mug Cake. While many mug cakes end up rubbery, this specific “molten” version stays moist and rich.
Here is a 5-minute prep, 2-minute cook chocolate cake recipe.
The 2-Minute Molten Mug Cake
Ingredients:
-
4 tbsp All-purpose flour
-
3 tbsp Sugar
-
2 tbsp Unsweetened cocoa powder
-
½ tsp Baking powder
-
3 tbsp Milk (any kind)
-
1 tbsp Neutral oil (vegetable or melted butter)
-
1 tsp Vanilla extract
-
The Secret: 1 tbsp chocolate chips or a dollop of Nutella
Instructions:
-
-
Mix: Find your largest microwave-safe mug. Add the dry ingredients and whisk with a fork until no lumps remain.
-
Wet: Stir in the milk, oil, and vanilla until the batter is smooth.
-
The “Molten” Center: Drop the chocolate chips or Nutella right into the center of the batter. Do not stir it in—it will sink and create a gooey center.
-
Nuke It: Microwave on high for 90 seconds.
-
Rest: Let it sit for 2 minutes before eating. This is the hardest part, but it allows the cake to finish setting so it isn’t “gummy.”
-
Other 15-Minute Options:
-
Gourmet Microwave Mug Cake: Top with a spoonful of peanut butter or a dash of sea salt immediately after taking it out.
-
The “Pan-Cake”: If you hate the microwave, you can make a thick pancake in a skillet, top it with chocolate chips, and put a lid on the pan to steam-bake it for 4 minutes. It tastes remarkably like a sponge cake.
Quick Tip: Every microwave is different. If the top looks wet after 90 seconds, give it another 10-15 seconds, but be careful—overcooking is what makes mug cakes turn into rubber!
