No Bake Pumpkin Spice Chex Cereal Bars with Peanut Butter

FAQ

Can I use natural peanut butter instead of regular?

Yes, but natural peanut butter may make the bars slightly less firm. Stir well before using and expect a slightly different texture.

How long do these bars need to set?

Allow about 2 hours for the bars to cool and set completely, plus additional time for the chocolate topping to harden if using.

Can I freeze these bars?

Yes, wrap individually and freeze for up to 3 months. Thaw at room temperature for about 30 minutes before serving.
