What Kind of Mug Should I Use?

Choose a microwave-safe mug that holds at least 12 ounces to prevent overflow. Ceramic mugs work best, and avoid anything with metal trim. A taller mug with straight sides ensures even cooking and a good rise without the batter bubbling over.

Options for Substitutions

• Oil: Swap vegetable oil with melted butter or coconut oil for a richer flavor.
• Flour: Use almond flour for a gluten-free version (note: texture will change).
• Sugar: Coconut sugar or brown sugar can replace white sugar for a deeper flavor.
• Milk: Any milk works here – dairy, oat, almond, soy.
• Chocolate Chips: Dark, milk, white, or even chopped chocolate chunks all work wonderfully.

Ingredients for This Simple Brownie In A Mug

• All-purpose flour: This gives the brownie its structure and body. It’s the base that holds everything together.
• Unsweetened cocoa powder: Brings in that deep chocolate flavor we crave in any good brownie.
• Granulated sugar: Adds sweetness and helps create a soft, slightly chewy texture.
• Salt: Just a pinch balances the sweetness and enhances the chocolate flavor.
• Vegetable oil: Keeps the brownie moist and tender. You can also use melted butter.
• Milk: Loosens the batter and ensures it stays soft and gooey. Any kind of milk works.
• Vanilla extract: Adds depth and a warm background note that enhances the overall taste.
• Chocolate chips: For melty, gooey chocolate pockets in every bite.

Step 1: Mix Dry Ingredients

In your microwave-safe mug, add 1/4 cup all-purpose flour, 2 tablespoons unsweetened cocoa powder, 2 tablespoons granulated sugar, and a pinch of salt. Stir well to combine the dry ingredients thoroughly.

---

Step 2: Add Wet Ingredients

Pour in 2 tablespoons of vegetable oil and 3 tablespoons of milk. Add 1/4 teaspoon vanilla extract. Mix until a smooth, thick batter forms. Scrape down the sides to make sure everything is well incorporated.

---

Step 3: Fold in Chocolate Chips

Stir in 1 tablespoon of chocolate chips (or more if you like it extra chocolatey). You can sprinkle a few more on top for that delicious melted topping effect.

---

Step 4: Microwave the Brownie

Microwave on high for 60 to 75 seconds. The brownie should be set on top but still a little gooey in the center. Microwave times may vary depending on your machine’s power, so start with 60 seconds and check.

---

Step 5: Cool Slightly & Enjoy

Let the brownie sit for a minute or two to cool slightly (and firm up a bit). Then grab a spoon and dig in straight from the mug, or top it with a scoop of vanilla ice cream for a next-level treat.

Tips for Perfect Simple Brownie In A Mug

• Use a mug that holds at least 12 oz to avoid overflow.
• Don’t over-mix the batter; stir just until combined.
• Microwave power varies, so keep an eye on your brownie after 60 seconds.
• For extra gooeyness, push a few chocolate chips into the center before microwaving.
• Add a pinch of instant coffee granules to intensify the chocolate flavor.

Watch Out for These Mistakes While Cooking

• Using a small mug: It will overflow. Always go for a roomy mug.
• Overcooking: Leads to a dry, rubbery texture. Start checking at 60 seconds.
• Too much flour or cocoa: Level your spoon when measuring to keep the balance right.
• Microwaving unevenly: Stir your batter well so it cooks consistently.
• Forgetting the salt: Even a pinch is essential to round out the sweetness.

Frequently Asked Questions

Can I make this brownie without cocoa powder?

Yes, but it won’t be a brownie! Without cocoa powder, it becomes more of a vanilla mug cake. You could try adding melted chocolate as an alternative.

Can I use almond flour instead of all-purpose flour?

You can, though the texture will be more crumbly and less chewy. Start with slightly less almond flour and adjust.

Is it okay to use water instead of milk?

Yes, but the result won’t be as rich. Milk adds creaminess and better texture.

How do I know if it’s done?

The top should look set and dry, but the inside should still be soft. Insert a toothpick — it should come out with a few moist crumbs.

Can I double the recipe?

You can double it, but use a larger bowl or divide between two mugs to avoid overflow. Microwave time will also increase slightly.
