Oreo Indulgent Mug Cake (Printable)

A soft, chocolatey mug cake using Oreo cookies, whipped up quickly and easily.

# What You'll Need:

→ Base

01 - 4 Oreo cookies
02 - 3 tablespoons milk
03 - 2 tablespoons all-purpose flour
04 - 1 tablespoon granulated sugar (optional)
05 - 1/4 teaspoon baking powder
06 - 1 small egg
07 - 1/2 teaspoon vanilla extract (optional)

# Directions:

01 - Place Oreo cookies in a microwave-safe mug and crush thoroughly with a fork until finely crumbled.
02 - Add milk and mix until the cookies are fully soaked and form a thick paste.
03 - Stir in flour, granulated sugar if using, and baking powder until well combined.
04 - Mix in the egg and vanilla extract if using until the batter is smooth and uniform.
05 - Microwave the mug on high for 1 minute 30 seconds. Check that the cake is set but still moist; if needed, microwave for an additional 10 to 20 seconds.
06 - Allow to cool for 1 to 2 minutes before enjoying directly from the mug.

# Expert Advice:

01 -
  • It's ready in five minutes flat, which means dessert happens on impulse instead of as a planned event.
  • The Oreo flavor is unapologetically bold—no fancy baking required, just that classic cookie taste you already love.
  • You eat it straight from the mug, which somehow makes it feel less guilty and more like a shared moment with yourself.
02 -
  • Don't skip the baking powder—I learned this the hard way when I tried to be clever and omit it, resulting in something between a cake and a fudgy pudding that never quite set.
  • The microwave time varies wildly depending on wattage, so start at 1 minute 30 seconds and check before adding more time; it's easier to add 10 seconds than to rescue an overcooked cake.
  • Use a microwave-safe mug that's taller than it is wide, because the batter rises as it cooks and you need room for that expansion.
03 -
  • Warm your mug under hot water for 10 seconds before adding the batter—this helps the cake cook evenly and rise more predictably.
  • If you want extra decadence without extending cook time, top it with a small dollop of whipped cream, a sprinkle of chocolate chips, or a scoop of vanilla ice cream the moment it comes out of the microwave.
