I highly recommend reading the blog post all the way through so that you don’t miss any tips or substitution suggestions and to ensure that you have all the ingredients and equipment required as well as understand the steps and timings involved.

I don’t know about you and your kids, but the afternoon slump – especially after school – is real! When my son was in school it was always about the afternoon snack to tide him over until dinner time.

Of course we want to feed our children (and ourselves) with healthy and nutritious foods, but a sweet treat every once in a while is just fine.

These peanut butter jelly bars are really easy to make, have that sweet and salty thing going on, and if you love PB&J sandwiches you’ll love these!

We used crunchy peanut butter and strawberry jam as the filling, and there is extra crunch from a sprinkling of salted peanuts on the top.

You may have most of the ingredients in your pantry already, so what are you waiting for?!

Make a tray of these peanut butter bars and wrap in wax paper for an easy grab-and-go snack, or to pop into lunchboxes (if your kiddo’s school allows peanut products).
