Why I love this recipe

• 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.No corn syrup is needed.

Ingredients needed

• Corn flakes. This simple cereal provides a lot of crispiness and allows the peanut butter flavor to shine through.
• Peanut butter. Both homemade and store-bought peanut butter will work so long as it is smooth. Avoid using peanut butter with added sugar.
• Maple syrup. I use pure maple syrup. It helps sweeten the bars and makes the cornflakes sticky enough to be shaped into bars.

Step 1- Make the mixture. Melt 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.

Step 2- Set. Transfer the sticky cornflake mixture to a 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.

Arman’s recipe tips

• 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.
• Use a sharp wet knife to slice the bars, to avoid the bars breaking apart.

Storage instructions

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.
