Hot Fudge Brownie | Brownie Sundae!
What could be better than a Hot Fudge Brownie Sundae during the hot summer days? Nothing. This dessert is a monster. So rich, decadent, fudgy, and sweet. Straight up ridiculous, but mama mia, that warm chocolatey brownie with the cold ice cream gets me every.single.time.
Main Ingredients Needed
- Brownies – this can be a store-bought brownie mix made with eggs, oil, and water or make homemade brownies!
Toppings
- Ice Cream – once again, use the store-bought stuff or if you have the time, make some homemade ice cream.
- Maraschino Cherries – and to top your sundae off, you’re going to need some bright red cherries!
- More Toppings – and to top it all off consider these other toppings! Nuts, sprinkles, chocolate syrup, caramel syrup, marshmallows, or fruit!
For the Hot Fudge
- Heavy Cream – this adds creaminess and some essential fat.
- Light Corn Syrup + Brown Sugar – both are used for thickening and sweetening.
- Cocoa Powder + Chocolate Chips – for all of the chocolatey flavor!
- Salt – to balance the sweet.
- Unsalted Butter – if all you have is salted butter, omit the salt.
- Vanilla – for a subtle flavor.
Looking for other chocolate sauces to use on this recipe? I’ve got you covered: Nutella Hot Fudge Sauce, Peppermint Chocolate Sauce, and Chocolate Ganache.
How to Make Hot Fudge Brownies
For full details on how to make Hot Fudge Brownies, see the recipe card down below 🙂
Step 1: Make Brownies
Start by stirring a boxed brownie mix together. See? EASY is the name of the game. Pour this into a greased 9×9 dish and pop it into the oven. Lick out the bowl. This is a very important step.
Step 2: Make Hot Fudge
While the brownies are cooking, you can make some hot fudge! Who knew it was so easy to make?! All you do is boil some cream, cocoa, corn syrup, salt, chocolate chips, and brown sugar together. Cook a few minutes, then remove from the heat and stir in some butter, vanilla, and a few more chocolate chips. That’s it! Can you believe it? Yeah, amazing.
Step 3: Spread Hot Fudge
And just like that, the brownies are done! Poke a whole bunch of holes in your brownies and pour on 3/4 cup of hot fudge. Make sure to make a bunch of holes! You want the whole thing drenched!! I used a fork, but if I were to do it again, I’d use something bigger…like the end of a wooden spoon or something. Spread the hot fudge over the warm brownies to make sure it gets into every crevice and let these sit for 10 minutes before serving.
Step 4: Top With Ice Cream
Cut into squares and top with vanilla ice cream. Serve right away and enjoy the heavenly goodness!
