Ingredients for Brownie in a Mug (Accurate Measurements)

Here are the exact ingredients needed to make this gooey Brownie in a Mug:

  • ¼ cup (30g) all-purpose flour
  • ¼ cup (50g) granulated sugar
  • 2 tablespoons (10g) unsweetened cocoa powder
  • ⅛ teaspoon salt (a small pinch)
  • 3 tablespoons (45ml) milk (whole milk works best)
  • 3 tablespoons (45ml) vegetable oil or melted coconut oil
  • ¼ teaspoon vanilla extract
  • 1 tablespoon chocolate chips (optional, for extra gooeyness)

These ingredients serve one person and create a perfect single portion of brownie in a mug.

Step-by-Step Instructions to Make Brownie in a Mug

  1. Combine dry ingredients. In your mug, mix together flour, sugar, cocoa powder, and salt until well blended.
  2. Add wet ingredients. Pour in milk, oil, and vanilla extract. Mix thoroughly with a fork or small whisk until you get a smooth batter with no dry pockets.
  3. Mix in chocolate chips. Stir in the chips or sprinkle them on top, depending on your texture preference.
  4. Microwave. Cook the mug in the microwave for 60–75 seconds on high. The brownie should be firm around the edges and slightly gooey in the center.
  5. Cool and enjoy. Let it cool for a minute or two, then top with ice cream or eat as-is.

For a festive twist, serve alongside cranberry apple crisp or a hot pumpkin chai latte.

Tips for the Perfect Brownie in a Mug

To make the best Brownie in a Mug, keep these helpful tips in mind:

  • Don’t overmix the batter. Stir just enough to combine everything.
  • Use good-quality cocoa powder for the richest flavor.
  • Microwave power varies; start with 60 seconds and check the texture.
  • For a gooey center, slightly undercook rather than overcook.
  • Always use a mug that allows the batter to rise—12 oz or more is best.

You can also serve it as a side to this unique vegetable chaat salad for a surprising sweet-savory combo.

Common Mistakes to Avoid When Making a Mug Brownie

Avoid these errors to ensure your Brownie in a Mug turns out great every time:

  • Too small a mug: The batter needs room to expand while cooking.
  • Overcooking: This is the quickest way to dry out your brownie.
  • Skipping the salt: Even a tiny pinch enhances the chocolate flavor.
  • Incorrect measurements: This isn’t a time to eyeball ingredients.
  • Adding too many mix-ins: Stick to small amounts to maintain texture.
