Hot Fudge Sundae

When I think of a hot fudge sundae, my mind typically pictures a tiny bit of soft served ice cream with a dab of whipped cream, some hot fudge, and maybe if I’m lucky a cherry on top. When you buy a hot fudge sundae from any fast-food restaurant, this is typically what you receive. This is not the case when you follow our recipe to make your own copycat Sonic Hot Fudge Sundae! 

What’s On It 

Your basic Sonic hot fudge sundae contains the following ingredients. 

Vanilla ice cream
Hot fudge
Whipped cream

When you create your own homemade version of Sonic’s hot fudge sundae, the sky is the limit as far as what is included in the toppings. 

Add Real Fruit

Real fruit can also be added to your copycat hot fudge sundae if you want! Some great fruit ideas to add are bananas, strawberries, raspberries, blueberries, pineapple, peaches, and even blackberries. If you enjoy fruit, try adding one of these to your sundae the next time you make it!

Add Mix-Ins

There are other things that you can also try mixing into your vanilla ice cream if you want! Try crushing up some Oreo’s, Reese’s peanut butter cups, brownie chunks, nuts, cookie chunks, Butterfinger, Heath bar, Andes mints, York peppermints, or even Rollo’s. Get creative and add your favorites to the ice cream. You could also try mixing up the ice cream flavors, with your favorite flavor too if you wanted!  

Add Toppings

Many topping options are available when you make your own copycat Sonic hot fudge sundae. Some of my favorite toppings to add are caramel sauce, nuts, homemade whipped cream, crushed candy bars, other sauces such as strawberry or raspberry, or even marshmallow fluff. Think about your favorites and don’t be afraid to experiment. 

There are so many ways you can get creative when making your own homemade sonic hot fudge sundaes. One of my favorite things to do when serving these to a group of friends is to choose a few of my favorite toppings and prepare them all ahead of time. Then set them all out and let everyone load their hot fudge sundaes with all their favorite toppings. Now that you have ideas on how to customize your own sundaes, let’s look at how to make the exact copycat for Sonic’s hot fudge sundae, then you can jazz it up to your liking! 

Hot Fudge

For the best hot fudge sundae, this recipe from the Pioneer Woman is our favorite.  With this recipe, you can make the hot fudge well in advance or before you begin to assemble your hot fudge sundaes. It is, however, important to make your hot fudge so that it has some time to cool off. You may make this way ahead of time, and refrigerate, or you may make it shortly before you wish to serve it. This hot fudge recipe will thicken up as it cools off. 

Whipped Cream

The whipped cream for these hot fudge sundaes may be from a can if you wish, or we have also included our favorite whipped cream recipe from scratch. To make your own whipped cream from scratch is quite simple, and only requires three ingredients. Please see our walkthrough below for details on how to make it.

Copycat Sonic Hot Fudge Sundae Recipe


½ gallon vanilla ice cream
Jar maraschino cherries

Hot Fudge (From The Pioneer Woman)

2 cups cocoa powder
2 cups sugar
2 cups heavy cream
1 cup butter
2 Tbsp vanilla extract

Whipped Cream

1 pint heavy cream
¼ cup powdered sugar (more if desire to be sweeter) 
1 tsp vanilla extract


Step 1: Hot Fudge

To start off, make your hot fudge. To make it, in a medium to large-sized saucepan, combine cocoa powder and sugar. Mix well. Add in heavy cream and stir until combined, and no lumps remain. Place your pan over medium heat and stir as it begins to warm up. Once your mixture is warm to the touch, add butter and stir as it melts. Once butter is melted remove from the heat, add vanilla, and stir to combine. Allow your hot fudge to rest for 5-10 minutes until it cools off. Store in the fridge in an airtight container until you are ready to use. 

Step 2: Whipped Cream

To make delicious homemade whipped cream pour your heavy cream into a mixing bowl. Whisk on high until stiff peaks form. Add powdered sugar and vanilla. Stir to combine. Set aside to use for topping. 

Step 3: Making Your Sundae

To make your copycat Sonic hot fudge sundae, take your glass and line the entire bottom with a layer of hot fudge. Scoop your ice cream and add it on top. Then top with whipped cream, a cherry, and a drizzle of hot fudge. Add more toppings if desired. Serve immediately and enjoy!

SONIC Hot Fudge Sundae With Nuts

Many people love nuts. Perhaps you are one, who enjoys eating nuts, on your ice cream. If you are, you should try adding some nuts to your hot fudge sundae. Simply prepare the sundae as instructed above, then top with nuts such as pecans, walnuts, almonds, or peanuts. If you really enjoy nuts, you could even try making your sundae using a flavor of ice cream such as butter pecan that includes nuts in the ice cream.

Sundaes & Cones

Sometimes, it is nice to take your ice cream to go. If you want, you could try putting your hot fudge sundae in a cone! Be aware that doing this might make quite a delicious mess, but it sure is good. 

Sonic – Hot Fudge Shake

You can easily make a hot fudge shake from the above recipe as well. To make this, simply prepare this recipe by adding your ice cream and hot fudge into a blender instead of a serving glass as you normally would. Add ¼ to ½ cup of milk to your blender and mix it up.

Recipe: Molten Chocolate Cake Sundae

Sonic’s molten chocolate cake sundae is also very easy to copy at home. To make this copycat dessert, you will prepare this similar to your hot fudge sundae. Only you will also prepare a cake or brownie for your ice cream and hot fudge to sit on top of. While any basic chocolate cake will work, I prefer making brownies. Simply prepare your brownies and allow them to cool. Then assemble your dessert by placing a piece of brownie or cake on a serving dish, scoop ice cream and place it on top of your brownie. Add your whipped cream and a cherry then finish off with a large drizzle of hot fudge over everything. If you love the hot fudge, you could even add a layer on top of your brownie, before adding your ice cream. Be sure to serve this dessert immediately and enjoy!
