A Healthy Mug Brownie is the perfect solution when you’re craving something chocolatey but don’t want to bake a whole pan. Let’s be honest—if you make a full batch, you’ll probably eat the whole thing. Instead, why not make a single-serving fudgy brownie in just minutes?

It’s rich, indulgent, and has a surprise burst of blueberries to make it even more special. Plus, it takes less than five minutes to whip up! So, if you’re craving something sweet but don’t want the guilt of an entire tray of brownies, this blueberry mug brownie is the perfect solution.

Ingredients You’ll Need

Dry Ingredients:

• 3 tablespoons all-purpose flour
• 3 tablespoons packed brown sugar
• 3 tablespoons cocoa powder
• A pinch of sea salt (or regular salt)

Wet Ingredients:

• 2 tablespoons melted unsalted butter (or coconut oil for a vegan option)
• 3 tablespoons milk (dairy or plant-based)
• ¼ cup fresh blueberries

Step-by-Step Instructions

Step 1: Choose Your Mug Wisely

Not all mugs are created equal! Pick one that’s microwave-safe and not your favorite—just in case things go wrong (which they won’t, hopefully!). If you are clumsy, wrap your mug in a thick sock for extra protection. But remember to remove it before microwaving!

Step 2: Mix the Dry Ingredients

Start by adding the flour, brown sugar, cocoa powder, and a pinch of salt to your mug. Stir everything together until the mixture looks like fine, powdery baking sand. If you want to have some fun with it, try building a tiny sandcastle to check the consistency. Once it crumbles nicely, you know you’ve mixed it just right.

The key here is to ensure the sugar is well incorporated so you don’t have clumps of sweetness later. The cocoa should blend smoothly with the flour, creating an even mix of dry ingredients that will set the foundation for your brownie.

Step 3: Add the Wet Ingredients

Now, pour in the melted butter and milk. Stir well until everything is combined and you have a smooth, thick batter. If you notice any dry clumps, mix them in thoroughly—you don’t want surprise powder pockets in your brownie!

👉 Vegan Option: Swap the butter for coconut oil and use almond, oat, or soy milk instead of dairy.

Step 4: Add the Blueberries

Time for the fun part! Toss in ¼ cup of fresh blueberries. You can leave them whole or mash them up a little to release their juices into the batter. Just don’t overdo it—too many crushed berries could turn your brownie into a blueberry soup. For more delicious meals, check out Philly Cheesesteak Stuffed Peppers or Chicken Parmesan Alfredo.

Step 5: Microwave to Perfection

Place your mug in the microwave (without the sock!) and cook on high for about 80 seconds. If the center still looks undercooked, heat it for another 20 seconds. Be patient—this little brownie will be hotter than the sun, so let it cool for 5-10 minutes before digging in.

Step 6: Enjoy Your Gooey Chocolate Treat!

Pair your mug brownie with a cold glass of unsweetened almond milk to balance the richness and keep your baking sand from drying out your soul. Then, grab a spoon and enjoy every warm, chocolatey, blueberry-filled bite.

Tips & Tricks for the Best Mug Brownie

• Use fresh blueberries– Frozen ones release too much moisture and may make the brownie too soggy.
• Don’t over-mix– Stir just until combined; over-mixing can make the brownie dense.
• Avoid overcooking– The brownie continues to cook even after you remove it from the microwave, so undercook it slightly if unsure.
• Test for doneness– Insert a toothpick; it’s done if it comes out mostly clean.
• Customize the flavors– Add chocolate chips, a handful of nuts, or a dash of cinnamon for extra depth.
• Enhance the indulgence– A drizzle of peanut butter or a scoop of vanilla ice cream on top makes it even better!
• Let it cool– Microwaved desserts get extremely hot, so give it a few minutes before digging in.

Mistakes to Avoid When Making a Healthy Mug Brownie

1. Overmixing the Batter – Mixing too much can make the brownie dense instead of soft and moist. Stir just until combined.
2. Using the Wrong Mug Size – A small mug may cause overflow. Use a 12-14 oz microwave-safe mug to allow space for rising.
3. Overcooking the Brownie – Microwaving it too long can make it dry and rubbery. Start with 80 seconds, then check before adding more time.
4. Adding Too Many Blueberries – Excess blueberries can make the brownie too watery. Stick to ¼ cup for the right balance.
5. Skipping the Cooling Time – The brownie will be extremely hot! Let it cool for 5-10 minutes to set properly before eating.

How to Store a Healthy Mug Brownie

A Healthy Mug Brownie is best enjoyed fresh, but if you need to store it for later, follow these storage tips to maintain its texture and flavor.

1. Short-Term Storage (Few Hours)
   If you plan to eat your brownie within a few hours, simply cover the mug with plastic wrap or a lid and keep it at room temperature for up to 4-6 hours. This helps prevent it from drying out.
2. Refrigeration (Up to 1 Day)
   To store it overnight, let the brownie cool completely, then wrap it in plastic wrap or transfer it to an airtight container. When ready to eat, microwave for 10-15 seconds to bring back its soft texture.
3. Freezing (Not Recommended)
   Mug brownies are meant to be quick, single-serving treats, and freezing can alter the texture, making them dry or rubbery when reheated. It’s best to avoid freezing and prepare a fresh batch instead.
