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. Oh my goodness……look at that crumb topping!!! Delish! Especially with peanut butter and sweetened condensed milk! Winner! Winner! Winner!

  2. In Minnesota it’s a law that school can’t start before Labor Day…so I find it so weird reading about everyone going back to school already! These bars look amazing. I love PB&J and I can not believe you were in your 20’s before you tried jelly!!

  3. Oh my gosh I LOVE gooey bars!! This version looks incredible Dorothy and I would totally go with the peanut butter chips – YUMMY!

  4. I was allergic to peanut butter as a child so that wasn’t my lunch box staple. When I eventually started eating pb and j it was with strawberry jam only. Neither of my kids would eat grape jam either. These bars cater to our jam pickiness, however, the crumbly topping may be my favorite part!

  5. WAHM = Hardest. Thing. Ever. And no one gets that you have a schedule, and a REALLY busy life, and they can’t just drop in at a moment’s notice or call and say, “Hey, we should for sure drag the kids to the zoo today!!” Well of course we should, I mean it’s not like I have a ton of deadlines and a pie in the oven. 🙂

    These look amazing Dorothy.

    Psssst .. . . be my neighbor.

  6. I love the combination of white chocolate, PB, and jelly! I can’t believe we are already talking about back to school. Where did the summer go!!!??

  7. Oh yum! These look delicious 🙂 I’ve loved PB&J since I was a kid – I still crave it sometimes!

  8. Such a great idea for a fun twist on gooey bars! So perfect for back to school too!
    Yeah, and working at home with (soon to be) 4 little ones? Not easy. Babies need their mama!
