Minimalist Baking: Just a Few Pantry Staples Needed
You probably have everything you need for this mug brownie recipe in your pantry right now. Flour, sugar, cocoa, milk, oil – basic ingredients that come together to create something truly special. It’s the perfect recipe for when you want dessert now without a trip to the store.
The Simple Ingredients for Your Dreamy Mug Brownie

Essential Ingredients List: What You’ll Need
Here are the simple components for your soon-to-be favorite dessert:
Flour, Sugar, Cocoa Powder: The Dry Basics
For this mug brownie recipe, all-purpose flour provides structure, sugar sweetens the deal, and cocoa powder delivers that rich chocolate flavor we all crave.
Milk, Oil, Vanilla: The Wet Essentials
Milk adds moisture, oil makes it fudgy, and a touch of vanilla extract enhances the overall taste.
Chocolate Chips: For That Extra Chocolate Gooeyness (Optional but Recommended)
While optional, chocolate chips take this mug brownie from great to truly decadent. I recommend semi-sweet or dark chocolate chips for the best flavor.
Ingredient Notes and Easy Swaps
Flour Alternatives: Gluten-Free Options Explored
Want to make it gluten-free? You can easily swap all-purpose flour for a gluten-free blend. Almond flour can also work, giving a slightly nuttier flavor.
Sugar Adjustments: Sweetness to Your Taste
Adjust the sugar to your preference. For a less sweet brownie, reduce the sugar slightly. If you like it extra sweet, stick to the recipe as is.
Whipping Up Your Mug Brownie: A Quick Guide

Step-by-Step Preparation Summary (Detailed Recipe in Card Below)
Making this mug brownie is incredibly straightforward.
Combining Dry Ingredients: The First Stir
First, you’ll whisk together the dry ingredients in your mug. This ensures everything is evenly distributed for the best texture.
Mixing in Wet Ingredients: Achieving the Perfect Batter
Next, stir in the wet ingredients until just combined. Don’t overmix! A slightly lumpy batter is okay.
Microwaving to Perfection: The 1-Minute Dessert
Finally, microwave for about a minute, or until just cooked through. The exact time may vary depending on your microwave.
Expert Tips for Microwaving Mug Brownies
Microwave Wattage Matters: Adjusting Cooking Time
Microwave wattages vary, so cooking time might need slight adjustments. Start with 60 seconds and check for doneness. If it’s still very liquid, microwave in 10-second intervals.
The Doneness Test: How to Know When It’s Ready
A toothpick inserted into the center should come out with moist crumbs for a fudgy brownie, or clean for a more cake-like texture. Don’t overbake!
Avoiding a Dry Brownie: Key to Moistness
Overbaking is the enemy of a good mug brownie. Watch it carefully and err on the side of slightly underbaked for the best fudgy result.

Troubleshooting & Must-Knows for Mug Brownie Success
Common Pitfalls to Avoid
Overbaking and Dryness: Watch Your Microwave Time
As mentioned, overbaking is the biggest risk. Keep a close eye on your brownie while it’s microwaving.
Ingredient Measurement Accuracy: Key for Texture
Especially with minimal ingredient recipes like this mug brownie recipe, accurate measurements matter. Use measuring spoons and cups for best results.
Frequently Asked Questions (FAQs)
While designed for the microwave, you can bake it in a preheated oven at 350°F (175°C) for about 12-15 minutes. However, the texture will be slightly different.
For an extra fudgy mug brownie recipe, add an extra teaspoon of oil, or a few squares of melted dark chocolate to the batter.
Yes! Combine the dry ingredients in a mug or small container ahead of time for even quicker dessert assembly later.
A standard 10-12 ounce mug works best. You want enough space for the brownie to rise slightly without overflowing.

Decadent 5-Minute Mug Brownie Recipe: Your Instant Chocolate Fix
Ingredients
- 4 tbsp all-purpose flour
- 4 tbsp granulated sugar
- 2 tbsp unsweetened cocoa powder
- 1/4 tsp baking powder
- 1/4 tsp salt
- 3 tbsp milk
- 3 tbsp vegetable oil
- 1/2 tsp vanilla extract
- 2 tbsp chocolate chips optional
Instructions
Combine dry ingredients:
- In a standard size mug, whisk together flour, sugar, cocoa powder, baking powder, and salt.
Add wet ingredients:
- Add milk, vegetable oil, and vanilla extract to the mug. Stir until just combined. Do not overmix; a few lumps are okay. Stir in chocolate chips if desired.
Microwave:
- Microwave on high for 60-90 seconds, or until a toothpick inserted into the center comes out with moist crumbs. Cooking time may vary depending on microwave wattage. Start with 60 seconds and add 10-second intervals if needed.
Cool slightly & Serve:
- Let cool for a minute before enjoying directly from the mug. Top with ice cream, whipped cream, or your favorite toppings if desired.
Notes
- Microwave Timing is Key: Microwaves vary in wattage, so the cooking time is approximate. Start with 60 seconds, and then check every 10-15 seconds until done. You want it just set but still slightly gooey in the center for the best fudgy texture.
- Don’t Overmix: Overmixing the batter can lead to a tougher brownie. Stir until the ingredients are just combined. A few lumps are perfectly fine!
- Mug Size Matters: Use a standard 10-12 ounce mug. Too small, and it might overflow; too large, and it might spread too thin and cook unevenly.
- Ingredient Temperature: For best results, use room temperature milk and oil. This helps the batter come together smoothly.
- Make it Vegan: Easily make this mug brownie vegan by substituting the milk with plant-based milk (like almond, soy, or oat milk). The taste and texture will remain wonderfully chocolatey.
- Add a Pinch of Espresso Powder: For a richer, more intense chocolate flavor, add a tiny pinch (about 1/8 teaspoon) of espresso powder to the dry ingredients. It enhances the chocolate without making it taste like coffee.
- Customize Your Toppings: Get creative with toppings! Besides ice cream, whipped cream, and chocolate sauce, try caramel sauce, chopped nuts, a sprinkle of sea salt, or even a dollop of peanut butter.
- Serving Suggestion: For an extra indulgent treat, serve your warm mug brownie with a cold glass of milk or a scoop of your favorite ice cream right in the mug.
- Make it Ahead (Dry Mix): To speed up your dessert even more next time, pre-mix the dry ingredients (flour, sugar, cocoa, baking powder, salt) in a small airtight container or zip-top bag. When a craving hits, just add the wet ingredients and microwave!
