It’s Back to School Week here at Crazy for Crust! It’s a weeklong celebration of school!

And when I say celebration, I really mean dancing the macarena, hands in the air, shaking my booty and chanting, “School is back in! School is back in!”

Well, almost. She starts next week…but I’m getting the party started early. Gotta be prepared!

There’s nothing like a summer to make you realize that working from home with a child on vacation is HARD. How do y’all do it with young ones? OMG.

I’ve come to realize that I really am a “work at home mom.” In the past, I considered myself a SAHM, who blogged. After reviewing everything this summer, I realized that I’m a WAHM…and a SAHM. Those are two really hard jobs to put together. Jordan has spent the summer at a lot of camps, a few playdates, and with a lot of TV.

And when several playdates got cancelled at the last minute, more TV. #icountonplaydates #noonegetsthat


Back to school. It’s the season of new. New clothes, new backpack, new teachers and books…and new promises to pack better lunches and make snacks from scratch.

And…it’s the season for PB&J, and new PB&J treats.

Like these Peanut Butter & Jelly Gooey Bars.

I’m kind of on a Gooey Bar kick. I’ve made Healthier Chocolate Gooey Bars and Funfetti Gooey Bars and I have so many other gooey bar recipes too! They are just so easy to make and are so versatile! I have a few more ideas up my sleeve, so keep an eye out for those!

Being Back to School Week, I naturally thought of PB&J Gooey Bars. Peanut butter and jelly seem to be iconic this time of year. I’ve never been a jelly or jam person, until recently. One day I was craving something so bad and somehow I realized I was craving jam on toast, even though I’d never had it.


And yes, I was in my 20s before I tasted jam. Or jelly. I am a picky eater, and I’m proud of it! 😉

Like all Gooey Bars, these start with a cake mix. The mix is made into a “crust” and pressed into a pan, and is then topped with sweetened condensed milk and other goodies.

Instead of using the traditional butter and egg combo for the crust, I used peanut butter and egg for this PB&J version. These are very peanut buttery!

The sweetened condensed milk got whisked with some seedless strawberry jam. Why it’s purple? I don’t know. But you could use grape or blackberry, or use jam or jelly. Whatever you have on hand works great!

I wanted to use peanut butter chips in this, but realized I was out half way through making them, so I used white chocolate chips and wrote the recipe to reflect either addition. I know that some of you can’t get peanut butter chips, so use what you have on hand!

These are my favorite gooey bar so far. I brought these to a PTC meeting and everyone loved them and can attest that I ate way too many of them myself. I’d meant to freeze some for the actual start of school. Yeah, that didn’t happen.

It just means I’ll have to make them again! Or, at least, another version.

I’m going to be celebrating school all year long…with more gooey bars!

  1. Hi Dorothy-
    I love these bars; they are an absolute favorite everywhere I take them. My only problem is when I mix the cake mix, eggs and peanut butter till the cake mix is incorporated it is not crumbly. It comes out like a thick cookie dough. To cover the top I have to pat it into small sheets of dough on my hand and place it on top. The crumb top in your picture looks much prettier.

  2. Love your recipes!!! Love all the all the variations as well thank you for sharing. And your creativity. Did I mention I’m 5 lbs from goal in weight watchers!!!! I’m gonna treat myself
