Description

Avoid the dreaded rubbery mug cake with this foolproof recipe! Soft, fluffy, and perfectly moist, this mug cake is quick to make and easy to customize. Whether you’re craving chocolate, vanilla, or a keto-friendly version, follow these steps to get the best results every time.


Ingredients

Scale
  • 4 tbsp all-purpose flour (or cake flour for a softer texture)
  • 2 tbsp sugar (brown sugar for extra moisture)
  • ¼ tsp baking powder
  • 3 tbsp milk (or dairy-free alternative)
  • 1 tbsp vegetable oil (or melted butter for richness)
  • ½ tsp vanilla extract
  • 1 tbsp chocolate chips (optional)

Instructions

  • Choose the right mug – A 12–14 oz microwave-safe ceramic mug works best.
  • Mix dry ingredients – In the mug, whisk together flour, sugar, and baking powder.
  • Add wet ingredients – Pour in milk, oil, and vanilla extract. Stir gently until just combined.
  • Optional add-ins – If using chocolate chips, fold them in lightly.
  • Microwave in short bursts – Start with 50 seconds, then check. If undercooked, microwave in 10-second intervals until set.
  • Let it rest – Allow the mug cake to sit for 1–2 minutes before eating to improve texture.

Notes

  • Avoid overmixing to prevent a tough, chewy texture.
  • Use cake flour for a softer cake.
  • Reduce microwave power to 70–80% if your wattage is 1000W+ to prevent overcooking.
  • Swap oil for butter for a richer flavor, or try coconut oil for a dairy-free option.
