  • Method: Microwaving is the cooking technique, but since it is not a listed method, the closest primary cooking method is Stove top (microwaving is often grouped similarly for quick cooking)—however to be precise, none is perfect. Since no microwave is listed, and stovetop is the closest, but the instructions say microwave explicitly, so primary method should be No-Cook (since no conventional cooking equipment applies). Given method options, best fit is No-Cook.

Description

This fudgy mug brownie is a quick and easy single-serving dessert made in just minutes in the microwave. Rich with cocoa and chunks of dark chocolate, it delivers deep chocolate flavor and a moist, fudgy texture without the need for eggs or baking. Perfect for satisfying a chocolate craving instantly with minimal cleanup.


Ingredients

Scale

Main Ingredients

  • 2 1/2 tbsp dutch process cocoa powder
  • 1 1/2 tbsp all purpose flour
  • 2 tbsp granulated white sugar
  • 2 tbsp oil (canola, vegetable or olive oil)
  • 2 tbsp water
  • 1 1/2 tbsp chopped dark chocolate


Instructions

  1. Mix dry ingredients. In an 8 oz microwave-safe mug, combine cocoa powder, all purpose flour, and granulated sugar. Whisk together thoroughly with a mini whisk to ensure even distribution and break up any lumps.
  2. Add wet ingredients. Pour in the oil and water, then whisk briskly until the batter becomes smooth and uniform, making sure there are no lumps of cocoa powder or flour.
  3. Incorporate chocolate chunks. Fold in half of the chopped dark chocolate into the batter inside the mug. Sprinkle the remaining dark chocolate on top of the batter for a melty chocolate topping.
  4. Microwave to cook. Microwave the mug on full power for about 40 seconds (based on a 1000 watt microwave). The brownie top should look mostly set but might still be slightly moist; adjust timing if your microwave wattage differs.
  5. Cool and serve. Allow the mug brownie to cool for a few minutes so it firms slightly and becomes fudgy. Enjoy it warm directly from the mug, ideally eating with a spoon as the texture is loose and cannot be removed as a whole piece.

Notes

  • Because the brownie is very rich and fudgy, the serving size is small—similar to a typical brownie slice.
  • The brownie rises only about two-thirds of the way in an 8 oz mug.
  • For photo purposes, the recipe was doubled, but it's best to make one single serving per mug for even cooking.
  • The brownie texture is loose and crumbly due to the absence of egg, so it's best eaten with a spoon straight from the mug.
  • If a firmer crumb is desired, substitute 1 tbsp of water with 1 tbsp of whisked egg to help bind the batter.
  • Eat the brownie warm shortly after cooking for optimal fudginess; as it cools, the texture becomes drier and crumblier.
