It is a showstopper for birthdays or anytime you want to wow a crowd, and you do not even need to make everything from scratch.

Every time I serve this at gatherings, there is not a crumb left — someone always asks for seconds and the recipe.
Ingredients
- Boxed chocolate cake mix: I love how reliable and foolproof it is Check the label and choose one with real cocoa for best flavor
- Large eggs: Fresh eggs ensure a better texture and rise Look for eggs with bright yellow yolks
- Water: Filtered water is best for a cleaner flavor
- Vegetable oil: Neutral oil keeps the cake moist Choose a fresh bottle for best results
- Pints of vanilla and chocolate ice cream: Softened ice cream spreads best Allow to sit at room temp for a few minutes before using
- Peanut butter: Creamy peanut butter works better for spreadability Choose a variety with no added sugar for perfect balance
- Whipped cream: Adds a fluffy finish I prefer homemade but store bought saves time
- Chopped Reese’s peanut butter cups: The star of the show Use fresh ones for that snappy bite
- Chocolate syrup: A finishing touch for eye catching drizzle Choose a sauce with a rich cocoa taste
Step-by-Step Instructions
- Make the Cake:
- Prepare boxed cake mix using eggs water and oil according to package directions Batter should be smooth and glossy Pour into two round pans greased for easy removal Bake at 350°F and check with a toothpick for doneness Let the cakes cool fully before proceeding as warmth will melt the ice cream
- Assemble the First Layer:
- Place one cooled cake layer on your chosen serving platter Use a serrated knife to level the top if needed Spread an even layer of soft vanilla ice cream all over the cake edge to edge for a clean look Scatter half the chopped Reese’s cups right over the ice cream pressing them gently in
- Build the Second Layer:
- Carefully set the second cake layer on top Press lightly so you have an even surface Spread softened chocolate ice cream evenly over this cake layer again working edge to edge
- Finish with Toppings:
- Spoon or pipe whipped cream all over the top and sprinkle the remaining chopped Reese’s cups over the cream For the finishing flourish drizzle chocolate syrup generously back and forth over the whole cake
- Freeze and Serve:
- Cover your assembled cake tightly and freeze for at least two hours to set up firm For clean slices dip your knife into hot water and wipe between cuts Serve straight from the freezer for perfect texture

My absolute favorite part is the gooey peanut butter swirl I have loved peanut butter since childhood and when my family first tried this together at a summer birthday we all agreed it was the most over the top fun cake we had ever had
Storage tips
This cake freezes beautifully Store it tightly wrapped in plastic or in an airtight container for up to five days Leftover slices can be wrapped individually and kept in the freezer so you always have a sweet treat ready
Ingredient substitutions
If you are not a fan of peanut butter cups swap in chopped chocolate bars or try caramel filled candies For a nut free version use sunflower seed butter and nut free chocolate If you do not have both ice cream flavors just use extra vanilla or chocolate

Serving suggestions
This is a complete dessert on its own but a scoop of coffee ice cream or some salty pretzels on top turns it into a real sundae celebration I love serving it after a cookout or when friends drop by unexpectedly
Recipe FAQs
- → How do I keep the cake layers from sliding?
Make sure the cake layers are completely cool before assembling. Slightly softened ice cream helps everything stick together, and freezing between layers ensures a stable structure.
- → Can I use different ice cream flavors?
Absolutely! Swap in your favorite ice cream flavors to tailor the dessert to your tastes—experiment with caramel, coffee, or cookies and cream for a fun twist.
- → What’s the best way to slice the cake?
Run a sharp knife under hot water, wipe dry, then slice through the cake. This helps achieve clean cuts through the frozen layers.
- → Do I need to make the chocolate cake from scratch?
No, a boxed mix works perfectly and saves time, but you can use your favorite homemade chocolate cake for an extra-special touch.
- → How far ahead can I assemble the sundae cake?
The assembled dessert can be stored in the freezer for up to two days before serving—just add final toppings before presenting it.
- → Can I make it nut-free?
Yes, simply substitute peanut butter and Reese’s cups with nut-free alternatives to accommodate allergies.
