Iced Peanut Butter and Jelly Cake Bars
Guess I’m a kid at heart, because I still love peanut butter and jelly! When I was thinking about what I wanted to share with you today, I knew I wanted to make a fun cake and this flavor combo quickly came to mind.
I love that this cake can be whipped up in just minutes, which makes it perfect to take to parties, picnics or just enjoying right at home with the family.
You are likely to have everything you need right in your pantry. Hope you enjoy this simple yet delicious cake!
Here’s your line up! Please picture a small box of vanilla instant pudding in the photo as well. Note that you do not have to use a sugar free cake mix. Just cleaning out my ol’ pantry 🙂
How to Make The Best Dessert Bars
Alright, it gets really tricky here, add all of your cake ingredients right to the mixing bowl 🙂
You know me and my egg shots. I just don’t get tired of them, lol!
Add your oil, sour cream and pudding mix (not pictured).
Don’t forget the peanut butter!
Now that we’ve got everything in the bowl, time to mix until well combined.
Perfect. Pour into your nice sheet pan.
Spread your cake nice and even.
Heat your jam for about 30 seconds then drizzle over your cake batter.
Run a knife through to swirl!
So pretty! Now let’s bake!
Ahhh, there we go.
Whisk your icing then drizzle over your warm cake….and eat 🙂

I made this, following your recipe exactly, and it was WONDERFUL!!! Stayed yummy and fresh in the fridge for several days!
I notice that you made this on a Silpat. Would you mind if we posted this on our website at http://www.silpat.org/ ? We will give you credit.
Your creativity never ceases to amaze me — these look so delicious! And so much fun for kids and adults!!!
What is the name of the mat you use in the bottom of the pan and how does it work?
Looks delicious!
I love this, I went and stocked up on these ingredients but then thought… What size pan is that? At the store I had a few size choices to choose from I tried to figure it out just by your pictures like “what’s the ratio of the pan to your stove” so hopefully I picked out the right one 🙂
What a great recipe!!! In the oven now and my house smells heavenly:) Cannot wait to share with my teacher friends in the morning for a special breakfast treat!!!
What an awesome idea! I bet kids love it! Have you tried it with any different jellys?
This looks great! Have you tried it with any different jellys?
The red swirls and white drizzel are driving me bonkers! I love peanut butter and have yet to make a peanut butter cake…great way of sweetening it up with some yummy sweet jelly. This is a great recipe and I’m looking forward to giving it a try!

Yum! I’m full from dinner, but I think I could find room for a piece of this right now!
Looks yummy. One question… I noticed you used sugar free cake mix. Does it make a difference if I used regular cake mix or would it be sweeter? Just asking!
I love the simplicity of all your recipes! They are the best! And really, who doesnt love PB&J??? Well, my husband doesnt, but I dont have to make it for him ;). Thanks for sharing Jenny!

PB& J is always in season with me…in any form. Cake form sounds about perfect.
And I love that you cleaned out some pantry items while making this recipe. Love that feeling when I can use up a box of this or that which was taking up space.
Thanks Averie! Hope you are doing well!
