I have made these incredible decadent quadruple chocolate brownies for many years – they are truly amazing and everyone loves them. But they are only a once-a-year treat for our family.
Why? Two reasons, really:
- They are rich (and full of calories).
- They are also kind of expensive.
Which pretty much makes it the perfect holiday treat, in my book! They’d also make a fun birthday or other type of special event treat. But they aren’t your run-of-the-mill brownies, that’s for sure.
In my book, that’s what makes them so wonderful.
I adapted this decadent brownie from a Food and Wine recipe that originally made 2 large pans of brownies and called for pounds of butter, chocolate, and a mind-boggling 16 eggs! Obviously this was not a recipe for the faint of heart.
After a few modifications, which included lessening the sugar for sure, the recipe still uses a fair amount of butter, eggs and chocolate, so it’s still a rich recipe. But with one bite and you will understand – it’s worth it.
So let’s make some brownies!
Quadruple Chocolate Decadent Brownie
Biggest Cooking Tip for Decadent Brownies
One of my biggest tips for this recipe (or any recipe that calls for melted unsweetened chocolate) is to use cocoa powder and oil as a substitute for the pound of unsweetened chocolate.
It’s about half of the cost of bar chocolate, are items most people have in their pantries (versus a bar of unsweetened chocolate – now sweetened chocolate is another thing…), and no one I’ve ever served these too has ever noticed a difference.
How do you substitute cocoa powder & oil for bar chocolate?
Every container of unsweetened cocoa powder should have the substitution equivalents on the back label: 3 TB. cocoa powder + 1 TB oil = 1 oz. of unsweetened chocolate.
So for this recipe, it would be:
- 1-1/2 cups cocoa powder + 1/2 c. oil = 1 pound unsweetened chocolate
You can use any oil you prefer, even melted coconut oil (I usually choose a neutral one like expeller-pressed sunflower) and then add it and the cocoa powder to the melted butter called for in this recipe. It’s really simple and actually quicker than melting that much chocolate.
Another tip that works with bar cookies to make them easier to remove from the pan and cut is to line your baking pan with parchment that extends up the long sides. These “handles” make it easy to grab and lift the brownies out when they are ready to be cut.
Making these brownies is about the same as any brownie recipe: you melt the chocolate, butter, and sugar together and then add the remaining ingredients. You can then just drizzle the three melted chocolates on top for follow the directions below to make the pretty chevron design.
To make the pretty decorative top, simply:
- Melt and drizzle three different melted chocolates on top of the dough (as you can see, perfection is not required – some of the chocolate will be dollops and some drizzles – it’s all good).
- Run a knife through the chocolate and the dough lengthwise.
- Then turn the knife and run it up the opposite way, going completely across the top which creates a sort of chevron pattern.
Baked, the pattern is a bit more subtle, but still lovely.
You’ll want to let the brownies cool completely – even refrigerate them overnight – before cutting since they are so fudgy.
I like to use a pizza cutter to cut them, it makes it really easy to get fairly straight lines and neat edges without having to stop and clean your knife.
To give these brownies at the holidays (or birthdays, special days, etc.), you can cut them into regular sizes and wrap 2 or 4 to a package (like shown) or cut into 12 large pieces to wrap individually leaving the recipients to cut them up in smaller pieces.
They freeze beautifully and last for months when frozen, so these are a great option for making ahead.
