Peanut Butter Cornflake Bars (2024)

These peanut butter cornflake bars are a delicious no bake dessert that combines the irresistible flavor of peanut butter with the satisfying crunch of cornflakes.

Crispy, sweet, crunchy, peanut buttery, and sticky.

That is how you’d describe cornflake bars. I grew up eating these at my friend’s birthday parties. Along with a chocolate or caramel slice, these were the birthday party staples!

Twenty years later, these no bake bars aren’t just reserved for parties anymore- they make a guilt free snack, too!

The best cornflake bars

Now, this isn’t your classic cornflake bar recipe. We skipped the corn syrup and refined sugar but kept the texture and flavor you’d expect. I made my mom try this very recipe and she couldn’t tell the difference!

• It’s only 3 ingredients. You need three pantry staples to make these bars. They don’t contain any dairy or gluten.
• Takes 5 minutes to make. Simply mix all ingredients and let the bars set. You won’t have to worry about snacks for the coming days.
• It doesn’t have added sugar. These cornflake bars are sweetened with pure maple syrup to avoid refined sugar.

How to make peanut butter cornflake bars

These 3-ingredient and no-bake cornflake bars are obviously very easy to make.

Start by melting the peanut butter and maple syrup in the microwave. Pour this mixture over the cornflakes and mix until fully combined. If the mixture is not sticky enough, add more maple syrup.

Now, transfer the sticky cornflake mixture into an 8×8-inch pan lined with parchment paper. Wet your hands and start pressing down the cornflakes in an even layer. Press firmly and refrigerate for 30 minutes or until firm. Slice into bars and serve.

Dietary swaps and substitutions

These bars are made of three components – crunchy cereal, creamy butter, and syrup to sweeten and hold everything together nicely. So long as you have all three components, you can switch things up to make these bars fit your preferences.

• Swap the peanut butter. Any smooth nut butter you have will work, like almond butter. If you are allergic to nuts, use sunflower seed butter instead.
• Switch the sweetener. You can use honey or any sticky sweetener of your choice to sweeten these bars. Light corn syrup and agave nectar will work too.
• Replace the cornflakes. If you don’t have cornflakes at home, substitute them with another simple cereal you have at hand. You may also enjoy rice crispy treats or cereal bars instead.

To store. Store cornflake bars in an airtight container in the fridge for up to 2 weeks. You can keep these bars at room temperature if you want them to be extra gooey.

To freeze. Freeze individually wrapped crunch bars for up to 2 months. Bring the bars to room temperature before eating them.
