The ingredients you’ll need

- Unsalted Butter: You can’t beat butter when it comes to creating that rich, melt-in-your-mouth texture. It makes the brownie base fudgy and decadent.
- Granulated Sugar: helps sweeten the brownie base and creates a soft, chewy texture. If you want your brownies to have that satisfying sweetness without being overly rich, this is the sugar to use.
- Brown Sugar: Maybe you’ve noticed brown sugar adds a bit of extra richness, and that’s because of the molasses content. It brings moisture to the brownies and adds a warm, caramel-like flavor.
- Eggs: the backbone of your brownie batter—they provide structure and moisture.
- Vanilla Extract: You can never go wrong with vanilla! It enhances all the other flavors and brings a nice depth to your brownies.
- All-Purpose Flour: You want enough to create a sturdy base for the fudge topping, but not too much that it becomes cakey.
- Cocoa Powder: If you’re looking for a deep, rich chocolate flavor, cocoa powder is your friend. It adds that dark, intense chocolate taste that makes brownies so satisfying.
- Salt: A pinch of salt is more than just seasoning—it helps to bring out the chocolate flavor.
- Baking Powder: helps to slightly lift the batter, making sure it’s not too dense. It gives the brownies a tiny bit of structure without losing their fudgy texture.
- Semi-Sweet Chocolate Chips: For the extra chocolatey punch, you need chocolate chips! Semi-sweet chocolate chips melt perfectly to create that gooey, melt-in-your-mouth texture.
- Sweetened Condensed Milk: For the fudge topping, sweetened condensed milk is your secret weapon. It makes the fudge super creamy and smooth, while adding just the right amount of sweetness.
How to Make your best double decker chocolate fudge brownie​
Preheat and Prepare
Start by preheating your oven to 350°F (175°C). Grease an 8×8-inch square baking pan lightly, then line it with parchment paper for easy removal.
This ensures your brownies come out easily after baking. If you don’t have parchment, just grease the pan with a little butter and a sprinkle of flour.
Make the Brownie Base
In a medium bowl, melt the butter in the microwave or on the stove. Once melted, add the granulated sugar and brown sugar into the butter. Stir them together until combined.
Next, add the eggs one at a time, stirring well after each addition. Add the vanilla extract and mix again.
In another bowl, whisk the flour, cocoa powder, salt, and baking powder until well combined. Slowly add this dry mixture into the wet ingredients, mixing until just combined. Be careful not to overmix—this will help your brownies stay fudgy!
Finally, fold in the semi-sweet chocolate chips.
Pour and Bake the Brownie Base
Pour the brownie batter into the prepared baking pan and spread it out evenly with a spatula. Pop the pan into your preheated oven and bake for 25 minutes.
You’ll know it’s done when a toothpick inserted into the center comes out with just a few moist crumbs (not wet batter).
While your brownie base is baking, you can prepare the fudge topping!
Make the Fudge Layer
In a saucepan, heat the butter over medium heat until fully melted. Add the semi-sweet chocolate chips and sweetened condensed milk. Continue stirring until the mixture is completely melted and silky smooth.
Once the fudge layer is smooth, remove it from the heat and stir in the vanilla extract. Set it aside to cool slightly.
Add the Fudge Layer
Once your brownie base is done and has cooled for about 10 minutes, spread the fudge topping evenly over the brownie base. Use a spatula to smooth it out, covering the entire top of the brownies.
Let It Set and Enjoy
Let the brownies sit at room temperature for about 20 minutes to allow the fudge to set. If you’re in a rush, you can place them in the fridge to speed up the process. Then Enjoy your Double Decker Chocolate Fudge Brownie!

What to Serve with double decker chocolate fudge brownie
Here are a few ideas to enhance your brownie experience:
A Scoop of Vanilla Ice Cream
What’s better than a fudgy brownie? A warm brownie paired with a scoop of cold, creamy vanilla ice cream! The sweetness of the ice cream contrasts perfectly with the richness of the chocolate, and the creamy texture balances out the dense brownie. You can also try mint chocolate chip or caramel swirl for a different twist.
Fresh Berries
Serve the brownies with a side of fresh berries like raspberries, strawberries, or blueberries. The tartness of the berries cuts through the sweetness of the brownies, providing a refreshing contrast. Plus, the burst of color makes the plate look even more delicious!
Whipped Cream or Chocolate Ganache
For an extra indulgence, top your brownies with some whipped cream or drizzle chocolate ganache over the top. The lightness of whipped cream balances the dense brownie, while ganache intensifies the chocolate experience.
A Cup of Coffee or Espresso
If you’re serving these brownies for dessert, a hot cup of coffee or espresso is a great choice.
The bitter notes of coffee complement the sweetness of the brownies, and it’s a classic pairing. You could also go for a cappuccino or mocha if you prefer a creamier beverage.
Milk
Sometimes, you can’t beat the classic combination of milk and brownies. A cold glass of milk (dairy or non-dairy) enhances the flavors of the brownies and is a perfect pairing for this rich treat. It also helps balance the texture of the fudge layer!
Salted Caramel Sauce
Drizzling salted caramel sauce over your brownies adds a sweet and salty flavor combo that will make your taste buds dance. The smooth caramel contrasts with the fudgy brownies, and the salt balances out the sweetness.

Top Tips for Perfecting Your Brownies
Use Room Temperature Ingredients
For a smoother batter and better texture, make sure your eggs and butter are at room temperature before you start baking.
Cold ingredients can cause the batter to seize up and result in uneven baking. Let your butter sit out for about 30 minutes and take the eggs out of the fridge a few minutes before using them. It’ll make mixing the batter easier and ensure your brownies bake more evenly!
Don’t Overmix the Batter
When adding the dry ingredients into the wet, mix just until combined. Overmixing can lead to tough, dense brownies rather than the rich, fudgy texture you’re aiming for.
It’s okay if the batter looks a little lumpy—that’s actually a good thing! This ensures your brownies stay soft and melt-in-your-mouth delicious.
Try a Little Coffee
For an extra depth of flavor, consider adding a tablespoon of brewed coffee (or espresso powder) to the brownie batter.
It’s not enough to make the brownies taste like coffee, but it really intensifies the chocolate flavor and gives the brownies a deeper, more complex taste. Just a little goes a long way!

Storing Tips for Your Double Decker Chocolate Fudge Brownie
Room Temperature Storage
If you have leftover brownies (lucky you!), they can be stored at room temperature in an airtight container for up to 3-4 days. Just make sure to place a piece of parchment paper between layers of brownies so they don’t stick together.
You’ll be able to enjoy them throughout the week without needing to refrigerate!
Refrigeration for Longer Freshness
If you need them to last a little longer, store your brownies in the fridge. Place them in an airtight container, and they’ll stay fresh for about 5-7 days.
Freezing for the Future
Want to save them for later? You can freeze your brownies! Wrap them tightly in plastic wrap, then foil, or place them in a freezer-safe bag. They’ll stay fresh for up to 2-3 months.
FAQ about Double Decker Chocolate Fudge Brownie
Can I substitute the sweetened condensed milk in the fudge layer?
Yes, you can substitute the sweetened condensed milk with regular heavy cream if you prefer. This will give the fudge layer a slightly different texture—richer and creamier. However, the sweetness will be less intense, so you might want to add a little more sugar or a tablespoon of honey to achieve the same level of sweetness.
How can I make this recipe gluten-free?
You can easily make a gluten-free Double Decker Chocolate Fudge Brownie by swapping the all-purpose flour with a 1:1 gluten-free flour blend. Additionally, adding a touch of xanthan gum (about 1/4 teaspoon) will help improve the texture and prevent the brownies from crumbling.Â
Can I add nuts to my Brownies?
Definitely! If you love a bit of crunch, add some chopped walnuts or pecans to your batter. Just fold them in before baking for an extra texture and flavor boost.
