Ingredients You’ll Need

You only need a handful of simple ingredients — probably already in your kitchen — to whip up this decadent brownie.

• All-purpose flour: Gives the brownie structure. Don’t overdo it to keep things fudgy.
• Unsweetened cocoa powder: The key to that deep, rich chocolate flavor. Go for a good-quality brand if possible.
• Sugar: Balances the cocoa and sweetens the whole brownie.
• Salt: Just a pinch elevates the chocolate and balances the sweetness beautifully.
• Milk: Any kind works here — dairy or plant-based. It brings moisture to the mix.
• Vegetable oil or melted butter: Keeps the brownie moist and indulgent. Butter adds a richer flavor; oil keeps it extra fudgy.
• Vanilla extract: A small splash adds depth and rounds out the chocolate.
• Chocolate chips or chunks (optional): Stir in or sprinkle on top for gooey pools of melted chocolate.

Variations

Want to switch things up? Here’s how to make this mug brownie your own:

• Nutty Crunch: Stir in a tablespoon of chopped walnuts or pecans for texture.
• Peanut Butter Swirl: Add a teaspoon of peanut butter before microwaving for a dreamy combo.
• Mocha Brownie: Add a pinch of instant coffee or espresso powder to intensify the chocolate flavor.
• Vegan Version: Use plant-based milk, and swap butter with coconut oil or vegan margarine.
• Gluten-Free: Sub with almond flour or a 1:1 gluten-free baking blend.

How to Make One-Minute Microwave Brownie

Step 1: Mix the Dry Ingredients

In a microwave-safe mug, stir together flour, cocoa powder, sugar, and salt until well combined.

Step 2: Add the Wet Ingredients

Add milk, oil (or melted butter), and vanilla extract. Stir thoroughly until no dry patches remain and the batter is smooth.

Step 3: Add Chocolate (Optional but Highly Recommended)

Fold in some chocolate chips or chunks. Press a few on top if you want that gooey top layer.

Step 4: Microwave

Microwave on high for 45–60 seconds. Keep a close eye — don’t overcook. It should be just set in the center and slightly gooey.

Step 5: Cool Slightly and Dig In

Let it sit for a minute to cool just a bit — it’ll thicken up slightly and won’t burn your tongue. Grab a spoon and enjoy warm!

Pro Tips for Making the Recipe

• Don’t Overmix: Stir just until combined to keep the texture soft and moist.
• Microwave Timing Varies: Start with 45 seconds and check. Microwaves differ in strength, so adjust as needed.
• Use a Wide Mug: Helps the brownie cook evenly and gives it that nice surface area for toppings.
• Add a Scoop of Ice Cream: Trust me — warm brownie + cold vanilla ice cream = heaven.

How to Serve

This brownie is fantastic straight out of the mug, but here are some fun ways to elevate it:

###Classic Combo
Top with a scoop of vanilla or salted caramel ice cream and a drizzle of chocolate syrup.

###Grown-Up Version
Dust with powdered sugar, add a pinch of sea salt flakes, and pair with an espresso or dark roast coffee.

###Kid-Friendly Treat
Top with whipped cream and colorful sprinkles — perfect for a quick after-school snack.

Make Ahead and Storage

Storing Leftovers

This is best enjoyed fresh, but if you need to, cover and refrigerate the mug for up to 1 day. Reheat in the microwave for 15-20 seconds before serving.

Freezing

Not ideal for freezing, but you can pre-mix the dry ingredients and store in a jar for instant brownie-making anytime.

Reheating

Microwave for 15-20 seconds to revive that fudgy warmth if your brownie cools down too much.

FAQs

Can I make this brownie without cocoa powder?
Cocoa powder is essential for the rich chocolate flavor, but in a pinch, you could substitute with melted chocolate chips or a chocolate spread. Just note the texture may change slightly.

How do I know when the brownie is done?
It should look set on top but still slightly soft in the center. Avoid overcooking — it’s better to undercook slightly for that gooey texture.

What size mug should I use?
Use an 8 to 12-ounce microwave-safe mug to give the batter room to rise and cook evenly.

Can I double the recipe?
You can, but it’s best to split it into two mugs to avoid overflow. Microwave one at a time for best results.
