I love making this Reese’s Ice Cream Sundae Cake when I want a dessert that feels over-the-top and unforgettable. Inspired by the classic flavors of Reese’s, I layer rich chocolate cake, creamy peanut butter ice cream, warm hot fudge, and a fluffy whipped topping into one irresistible frozen treat. Every bite gives me chocolate and peanut butter in the best possible way.
Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
For the cake:
1 box chocolate cake mix (plus ingredients needed to prepare)
For the peanut butter ice cream layer:
1/2 gallon peanut butter ice cream, softened
For the hot fudge sauce:
1 jar hot fudge topping (about 12 oz), warmed slightly
For the topping:
1 container whipped topping (Cool Whip or homemade whipped cream)
1 cup Reese’s Pieces or chopped Reese’s Peanut Butter Cups
Optional: chopped peanuts or mini chocolate chips
Directions
Bake the cake:
I prepare the cake mix according to the package directions. I bake it in a 9×13-inch pan and let it cool completely before adding any layers.
Layer the ice cream:
Once the cake is fully cooled, I spread the softened peanut butter ice cream evenly over the cake. I make sure it reaches the edges for a clean layered look. I freeze it for at least 1 hour, until it becomes firm.
Add fudge layer:
I drizzle the slightly warmed hot fudge sauce over the ice cream layer, spreading it gently if needed. Then I return the pan to the freezer for another 30 minutes so the fudge can set.
Top it off:
I spread whipped topping evenly over the fudge layer. Then I sprinkle generously with Reese’s Pieces or chopped peanut butter cups. If I want extra crunch, I add chopped peanuts or mini chocolate chips.
Freeze until serving:
I freeze the entire cake for at least 2 hours before slicing. When I’m ready to serve, I let it sit at room temperature for 5–10 minutes so I can slice it more easily.
Servings and timing
I usually cut this cake into 12 to 15 servings, depending on how large I want each slice.
Preparation time: about 20 minutes (not including baking and cooling)
Baking time: 25–35 minutes (depending on the cake mix instructions)
Freezing time: about 3 1/2 to 4 hours total
Total time: approximately 5 hours including cooling and freezing
I often prepare it the day before serving, which makes entertaining much easier for me.
Variations
I sometimes swap the peanut butter ice cream for vanilla or chocolate ice cream when I want a slightly different flavor balance.
For an extra rich taste, I like to use homemade hot fudge sauce instead of store-bought.
If I want even more peanut butter flavor, I fold crushed peanut butter cups directly into the ice cream layer before spreading it over the cake.
I also experiment with different toppings, like chocolate syrup drizzle, caramel sauce, or a mix of chopped candy bars.
Storage/Reheating
I store the cake tightly covered in the freezer. I either wrap the pan with plastic wrap and foil or transfer slices to an airtight container.
When I want to serve leftovers, I let a slice sit at room temperature for about 5–10 minutes to soften slightly. I do not reheat it, since it is meant to be enjoyed as a frozen dessert.
For best texture and flavor, I try to enjoy it within one week.
FAQs
Can I make this cake ahead of time?
Yes, I often make it a day in advance. I keep it frozen until I’m ready to serve, which actually improves the layering and makes slicing cleaner.
Can I use homemade cake instead of a box mix?
Absolutely. I sometimes bake my favorite homemade chocolate cake recipe in a 9×13-inch pan and use it as the base.
How do I keep the ice cream layer smooth?
I let the ice cream soften slightly at room temperature before spreading. I work quickly and use a spatula to create an even layer before returning it to the freezer.
Can I use a different candy topping?
Yes, I like experimenting with different chocolate candies, crushed cookies, or even a drizzle of caramel sauce on top.
What if I don’t have peanut butter ice cream?
If I don’t have peanut butter ice cream, I use vanilla or chocolate and add swirls of peanut butter or crushed peanut butter cups for a similar flavor.
Conclusion
I find this Reese’s Ice Cream Sundae Cake to be one of the most satisfying desserts I can make with minimal effort. I love how the layers come together into a rich, creamy, chocolate-peanut butter masterpiece. Whenever I serve it, I feel confident that it will impress everyone at the table while still being simple and fun for me to prepare.
