  • All you need for a quick cinnamon roll mug cake.

Instructions

  • In a microwave-safe mug, melt the butter and swirl in the brown sugar and cinnamon until smooth.
  • Add flour, baking powder, salt, milk, and vanilla directly into the mug; stir until combined and no dry spots remain.
  • Microwave on high for about 60–75 seconds until the cake rises and appears set on top.
  • Allow it to cool slightly before drizzling with powdered sugar glaze or a bit of cream cheese frosting if desired.

Notes

If you’re dairy-free, swap butter for coconut oil and milk for almond milk; the flavor remains indulgent.
For an extra gooey center, undercook by about 5 seconds; it will finish setting as it rests.
Store leftover glaze in an airtight container in the fridge for up to three days—it’s excellent over pancakes or waffles too.
The cinnamon roll mug cake can also be dressed up with nuts or chocolate chips for added texture.
To batch-prep, pre-measure dry ingredients into small jars for grab-and-go mug cake kits.
