📋 Ingredient Notes & Substitutions
Unsalted butter: You can also try using salted butter for a slight salted caramel twist!
Coconut sugar: Coconut sugar provides a rich and deeper flavor compared to regular golden or white sugar. I have made these peanut butter squares using golden granulated sugar but it wasn’t as flavourful or as rich as using the coconut sugar.
Peanut butter: I love to use crunchy peanut butter in this recipe as it also adds crunchy bits of peanut butter throughout the mixture. You can also use smooth peanut butter.
Honey: Use runny honey for this recipe. I have not tested these peanut butter squares with Rice Krispies using raw solid honey that is more crystallized.
Rice Krispie cereal: Also known as rice bubbles in Australia, this is a puffed rice cereal that you can find in any supermarket.
🥣 Step By Step Instructions (with photos)
There is a full and detailed recipe card at the bottom of this post.
Step one: In a medium-sized pot, add butter, sugar, and honey. Place over low heat and allow ingredients to gently and slowly melt. Make sure it doesn’t bubble whilst it’s melting.
Step two: Bring to a boil and once boiling rapidly, boil for 1 minute, stirring occasionally with a wooden spoon or spatula to avoid burning on the base of the pan. Turn the heat off after 1 minute.
Step three: Add in Rice Krispies and stir them through until well combined.
Step four: Pour mixture into lined pan, be careful it’s hot! Spread it out evenly. Carefully transfer the pan to your refrigerator to chill for 1-2 hours or until completely set and firm. Once set, remove from the pan and onto a cutting board. Take a sharp knife and cut into squares or desired sizes. Serve and enjoy!
💭 Expert Recipe Tips
- When first melting the ingredients together, do not allow the mixture to bubble, keep it on low heat and let it gently melt.
- When you’re ready to bring the mixture to a boil, only boil it for 1 minute, any longer and the final squares will be a hard/firm caramel texture instead of soft and chewy.
- Be careful when pouring the hot mixture into your baking pan as it just finished boiling, it will be very hot to handle.
- To make it easier to transfer to the refrigerator to set, place your baking pan with the mixture inside on a flat baking sheet and carry it to your fridge to avoid potentially burning your hands.
⏲️ Storage Instructions
- Store these peanut butter squares with Rice Krispies in an airtight container, refrigerated, for up to 1 week. Storing them in the refrigerator will keep them firm but still soft and chewy. If you prefer them even more on the softer side, store your peanut butter squares in an airtight container, in a dry and dark pantry, for up to 1 week.
- If it’s during the spring and summer months and your home is warm and humid, you might like to store your Rice Krispie peanut butter squares in the refrigerator and not in the pantry as they can begin to melt if the room temperature is too hot.
💬 Recipe FAQ’s
No, these squares are different from regular peanut butter Rice Krispie treats because this recipe is made without marshmallows. The consistency of these Rice Krispie peanut butter squares is like a soft and chewy caramel fudge.
Creating a sticky caramel mixture on the stove is what sticks together these peanut butter Rice Krispie squares without using marshmallows.
Boiling the mixture for longer than the required 1 minute will make these squares hard. You’re essentially making a caramel when you boil the mixture and the longer it boils, the harder the caramel will turn out after it’s been refrigerated.
To achieve soft and chewy textured peanut butter Rice Krispie squares, only boil the mixture for 1 minute.
You can warm them back up in the microwave or a low oven until the squares soften. Another tip is to not store them in the refrigerator as the cold will make them even harder, instead, store them in your pantry.
