A white mug filled with a rich, dark chocolate cake that has a slightly rough top layer dotted with melted chocolate chips; the cake is cracked open near the top to reveal a gooey, melted chocolate center that is thick and glossy, dripping slightly over the edge of the mug down the side; steam rises gently from the hot dessert, adding warmth to the scene; a spoon lifts a scoop of the moist, dark brown cake with some molten chocolate clinging to it, highlighting the softness inside; all this sits on a white marbled surface with a smooth, blurred brown background. photo taken with an iphone --ar 4:5 --v 7

Ingredients

  • 1/4 cup (30g) all-purpose flour
  • 1/4 cup (50g) granulated sugar
  • 2 tablespoons (10g) unsweetened cocoa powder
  • A pinch of salt
  • 2 tablespoons (30ml) vegetable oil (or melted butter)
  • 3 tablespoons (45ml) water
  • 1/4 teaspoon vanilla extract (optional)
  • 1 tablespoon chocolate chips or chopped chocolate (optional)

Instructions

  1. Step 1: In a microwave-safe mug (about 10–12 oz), mix the flour, sugar, cocoa powder, and salt thoroughly using a fork or small whisk.
  2. Step 2: Add the vegetable oil, water, and vanilla extract if using. Stir until the batter is smooth and free of lumps.
  3. Step 3: Fold in chocolate chips or chopped chocolate for an extra gooey center, if desired.
  4. Step 4: Microwave on high for 60 to 90 seconds. The surface should be set but the center slightly gooey—avoid overcooking.
  5. Step 5: Let the brownie cool for 1–2 minutes before eating. Enjoy it plain or topped with whipped cream, ice cream, or chocolate syrup.

Tips & Variations

  • Use melted butter instead of oil for a richer flavor.
  • Add a pinch of cinnamon or espresso powder to deepen the chocolate taste.
  • Try mixing in a spoonful of peanut butter or caramel for a different twist.
  • Adjust microwave time based on your appliance to avoid dryness.

Storage

This mug brownie is best enjoyed fresh but can be stored covered in the fridge for up to 2 days. Reheat briefly in the microwave to soften before eating, but avoid overheating to keep the gooey texture intact.

FAQs

Can I use a different type of flour?

All-purpose flour works best for texture, but you can try whole wheat flour with slightly denser results. Gluten-free blends may also work but might alter the texture.

What if I don’t have vanilla extract?

Vanilla extract is optional and mainly adds flavor depth, so it’s fine to omit it if you don’t have any on hand.
