Ingredients You’ll Need
Part of the magic of this Flourless Chocolate Mug Brownie is how incredibly simple the ingredient list is. Each item plays its own delicious role, giving you that crave-worthy texture and flavor in every spoonful. Here’s what you’ll need and why you need it:
- Unsweetened cocoa powder: Delivers intense, pure chocolate flavor and that classic brownie color.
- Almond butter (or peanut butter): Adds richness, moisture, and a subtle nutty depth—plus, it helps bind everything together without flour.
- Maple syrup (or honey): Naturally sweetens the brownie and keeps it moist, with a touch of caramel-like warmth.
- Milk (dairy or non-dairy): Brings the batter together and ensures a tender, fudgy crumb.
- Vanilla extract: Enhances the chocolate flavor and adds a lovely aromatic note.
- Pinch of salt: Balances the sweetness and intensifies the chocolate taste.
- Optional chocolate chips: For extra melty chocolate pockets—trust me, you want these!
How to Make Flourless Chocolate Mug Brownie
Step 1: Mix Your Ingredients
Start by grabbing your favorite microwave-safe mug (make sure it’s a generous size to avoid overflow). Add the cocoa powder, almond butter, maple syrup, milk, vanilla extract, and a pinch of salt directly into the mug. Stir everything together with a fork or small whisk until you have a smooth, glossy batter with no streaks of cocoa or lumps of nut butter remaining.
Step 2: Add Chocolate Chips (Optional but Highly Recommended!)
If you’re a true chocolate lover, sprinkle in a tablespoon of chocolate chips and gently fold them into the batter. These melt into gooey pockets that make each bite of the Flourless Chocolate Mug Brownie even more luxurious.
Step 3: Microwave to Perfection
Pop your mug into the microwave and cook on high for 45 to 60 seconds. Keep a close eye on it—microwaves vary, so start with 45 seconds and check to see if the top looks set but the center is still a bit soft. If needed, add a few more seconds. The goal is a brownie that’s fudgy and moist, not dry.
Step 4: Cool and Enjoy
Let your Flourless Chocolate Mug Brownie cool for 1 to 2 minutes right in the mug. This lets it finish setting and makes it easier to eat. Then grab a spoon and dig in—no need to unmold or slice, just pure, instant chocolate bliss.
How to Serve Flourless Chocolate Mug Brownie

Garnishes
Elevate your mug brownie by topping it with a scoop of vanilla ice cream, a dollop of whipped cream, or a sprinkle of flaky sea salt. Fresh berries or a drizzle of melted chocolate also make for beautiful, tasty finishing touches.
Side Dishes
For a complete dessert experience, serve your Flourless Chocolate Mug Brownie alongside a fresh fruit salad, a handful of toasted nuts, or even a tall glass of cold milk or hot coffee. The contrast of flavors and textures will make your treat feel extra special.
Creative Ways to Present
Transform your mug brownie into a mini sundae bar by setting out various toppings like mini marshmallows, crushed cookies, or caramel sauce. Or, if you’re feeling fancy, serve the brownie in an elegant teacup with a tiny spoon for a playful, elegant twist.
Make Ahead and Storage
Storing Leftovers
If you somehow resist finishing your Flourless Chocolate Mug Brownie in one go, cover the mug tightly with plastic wrap and store it in the refrigerator for up to 2 days. The texture will stay moist and fudgy, perfect for sneaking a bite later.
Freezing
While this dessert is best enjoyed fresh, you can freeze any leftovers. Let the brownie cool completely, remove it from the mug if possible, wrap it well in plastic wrap, and store in an airtight container. Freeze for up to 1 month. Thaw overnight in the fridge before reheating.
Reheating
To bring your brownie back to life, microwave the refrigerated or thawed portion in the mug for 10 to 15 seconds until just warmed through. Be careful not to overheat, as it can dry out quickly.
FAQs
Can I use a different nut butter or make it nut-free?
Absolutely! You can substitute with cashew butter, sunflower seed butter for a nut-free option, or even tahini for a fun flavor twist. Just keep in mind the taste will change slightly depending on what you use.
What if I don’t have a microwave?
No worries! You can bake the Flourless Chocolate Mug Brownie in an oven-safe ramekin at 350°F (175°C) for about 10–12 minutes, or until set on top but still a bit soft in the center.
Can I double the recipe for two servings?
Yes, you can double the ingredients and divide the batter between two mugs. Microwave each mug separately to ensure even cooking and the perfect gooey texture.
How do I make it extra gooey?
For an ultra-gooey Flourless Chocolate Mug Brownie, microwave for the shorter time (about 45 seconds) and add a few extra chocolate chips in the center before cooking. Top with ice cream for the ultimate molten effect.
Is this recipe suitable for vegans?
It sure can be! Just use plant-based milk and swap maple syrup for honey if needed. Make sure your chocolate chips are dairy-free, and you’ll have a vegan mug brownie in minutes.
