Brownie in a Mug

(By Elise Bauer; Simple Recipes)

Saving lives by blood donation is a huge deal and ranks high up on the list of things we love about you. So while we would love to bake you a triple chocolate cake, we think this brownie in a mug will be a good alternative. Give it a try this school holiday, then tag @thewcbs and #Youngbloodsaveslives while we pop the kettle for you.


  • 2 tablespoons butter, mild extra virgin olive oil, or neutral oil
  • 1/4 cup (30 g) flour
  • 3 tablespoons (35 g) sugar
  • 2 tablespoons (13 g) natural unsweetened cocoa powder
  • Pinch salt
  • Tiny pinch cinnamon, optional
  • 3 tablespoons (44 ml) milk, water, or coffee
  • 1/8 teaspoon vanilla extract
  • Ice cream, whipped cream, or heavy cream, for serving


Put the butter in a small microwave-safe bowl or ramekin and microwave for 30 seconds. If it’s not melted after that, continue to microwave in 10-seconds bursts until it is.

  1. Place the flour, sugar, cocoa, salt (if using unsalted butter), and optional cinnamon in a microwave-safe ceramic mug. Stir with a fork until it resembles brown sand and there are no clumps.
  2. Stir in the butter (or oil) with a fork until a paste forms. Then add the milk (or water or coffee) and vanilla, and stir with the same fork until smooth. The batter may look a little thin, but don’t worry—that’s how it’s supposed to be.
  3. Cook in the microwave: Microwave, uncovered, on high power for 1 minute. You may need to adjust the time for less or more powerful microwaves. If you don’t know the power level on your microwave, start with 1 minute and continue cooking in 10-second increments until the brownie is done. For a 1000-watt microwave, 1 minute is good; for 1650-watt microwaves, we recommend 1 minute and 10 seconds. After cooking, the brownie should still look a tad moist, not dry. Some wet-looking spots are okay; those will set up as the brownie rests.
  4. Let the brownie rest for 4 minutes. The brownie inside is very hot and still cooking, even though it’s not in the microwave. It may be hard, but the wait is worth it! It gives the brownie a better flavour and texture.
  5. Serve with a scoop of vanilla ice cream or a small dab of cream (whipped or unwhipped).
