Oreo Classic Chocolate Cake (Printable)

A quick indulgent chocolate mug cake made by combining crushed Oreos with simple pantry staples.

# 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)

# Steps:

01 - Place Oreo cookies in a microwave-safe mug and thoroughly crush with a fork until finely crumbled.
02 - Add milk to the crushed Oreos and mix until it forms a thick, soaked paste.
03 - Stir in all-purpose flour, granulated sugar if using, and baking powder until evenly combined.
04 - Mix in the small egg and vanilla extract if desired until the batter is smooth and uniform.
05 - Cook in the microwave on high power for 1 minute 30 seconds. Check that the cake is set but moist; if necessary, heat an additional 10 to 20 seconds.
06 - Allow the mug cake to cool for 1 to 2 minutes before enjoying directly from the mug.

# Expert Advice:

01 -
  • It's genuinely faster than ordering delivery, and somehow tastes more indulgent than it should.
  • No mixing bowls, no cooling racks, no guilt about dirtying the whole kitchen for dessert.
  • The cookies dissolve into the cake, creating pockets of fudgy sweetness that feel like a secret.
02 -
  • Microwave times vary wildly by wattage—start with the shorter time and check often; undercooked is forgivable, overdone is ruined.
  • The cake continues to cook slightly after you pull it out, so err on the side of slightly underbaked if you want that moist, fudgy center.
03 -
  • The thicker you make your initial paste, the more fudgy your final cake will be—I prefer almost sludgy at the beginning.
  • If your microwave runs hot, start with 1 minute and add time in 10-second increments; if it runs cool, you might need the full 2 minutes.
