Tips & Tricks

- Don’t skip softening the peanut butter – cold peanut butter won’t mix smoothly with the condensed milk.
- Space your holes about an inch apart and make them deep enough to reach the bottom of the cake.
- Pour the peanut butter mixture slowly so it has time to soak into each hole instead of running off the top.
- Let the cake chill overnight if possible – the flavors get even better and it’s easier to cut clean slices.
- Use kitchen shears to cut the mini peanut butter cups in half – much easier than a knife.

Frequently Asked Questions
Absolutely! You can use any yellow cake recipe you love, just bake it in a 9×13 pan. The poke method works the same way.
It keeps covered in the refrigerator for up to 5 days. Trust me, it rarely lasts that long in my house!
I don’t recommend freezing this cake because the whipped topping and peanut butter mixture don’t freeze well. It’s best enjoyed fresh from the fridge.
Variations & Add-Ins
- Make it chocolate peanut butter by using chocolate cake mix instead of yellow.
- Add a layer of hot fudge between the peanut butter mixture and whipped topping for extra decadence.
- Swap the caramel for chocolate sauce if you prefer a deeper chocolate flavor.
- Use crunchy peanut butter instead of creamy for extra texture in every bite.
