Cooking methods
Preparation steps
- Roast the pumpkin with the skin on, scoop out the softened flesh, blend until smooth, and store it in the fridge until ready to use.
Cooking instructions
- Mix the wet ingredients: Add the pumpkin puree, melted butter, egg, and vanilla extract to the dry ingredients in a separate bowl, stirring until smooth and well combined.
- Transfer to a mug: Pour the batter into a fresh, microwave-safe mug. To avoid overflow, it's recommended to use a slightly larger mug or microwave in 30-second intervals, checking frequently.
- Microwave: Microwave on high for 1 minute and 30 seconds to 2 minutes, depending on your microwave’s power. The cake should be set but still slightly moist in the center.
- Cool: Let the mug cake cool for 1-2 minutes before enjoying.
Chef's pro tip
A common mistake when making this mug cake is overcooking it in the microwave, which can lead to a dry texture. To avoid this, start checking the cake after 1 minute and cook in 15-second intervals until the center is just set and slightly moist.
