Why You're Going To Love This Recipe
Let me start off by saying... there's a LOT to love about my Peanut Butter Slice recipe:
- no-bake - the perfect slice to make when you're craving something sweet but don't want to turn the oven on! Just mix and chill.
- quick & easy - whether you're a beginner baker or an experienced cook, there's no doubt that perfecting a no-bake slice recipe is achievable by absolutely anybody. And with just 10 minutes prep time, this couldn't be quicker to make!
- Reeses Peanut Butter Cups - if you love the famous peanut butter cups made by Reeses, then this is the slice for you! It has exactly the same creamy, melt-in-your mouth peanut butter flavour! (I've been truly devastated ever since Lindt discontinued their peanut butter Lindt Balls)....
- freezer-friendly - my peanut butter slice freezes and defrosts beautifully. Simply store in an airtight container in the freezer for up to 3 months and allow to defrost before consuming. I recommend placing sheets of grease-proof baking paper between each layer of slice when freezing.
- great for fetes & bake sales - this creamy peanut and chocolate flavoured slice is always popular with kids and adults alike.
What You Need
Just 5 basic ingredients!
Note: please scroll to the recipe card at the bottom of the post for the ingredient quantities and the full detailed method.
- butter - you can use salted or unsalted butter for this recipe. Personally, I prefer salted butter as it brings out the delicious sweet, salty, and creamy peanut flavours.
- peanut butter - it's important to use creamy store-bought peanut butter in this recipe (either smooth or crunchy). Natural or homemade peanut butter are not suitable for this recipe. I recommend Kraft or Bega peanut butter.

- icing sugar - also known as confectioners sugar or powdered sugar.

Expert Tips & FAQ
It's absolutely impossible to go wrong with this simple peanut butter slice recipe.
Here's a few simple tips for making it perfect every single time!
No! As much as I love homemade peanut butter and the natural store-bought versions, they're just not suitable for this recipe. You will need to use a creamy store-bought peanut butter like Kraft or Bega brands (either smooth or crunchy).
Icing sugar is also known as confectioners sugar or powdered sugar. It's a very fine white powdered sugar. You can use either 'pure' icing sugar or 'soft icing sugar mixture' in this recipe.
As this recipe contains peanut butter, it is not suitable for lunch boxes at schools with a nut-free policy. Check your schools policy to be sure.
This slice can be stored in an airtight container in the fridge for up to 7 days.
Store in an airtight container in the freezer for up to 3 months and allow to defrost before consuming. I recommend placing sheets of greaseproof baking paper between each layer of slice when freezing.
