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 🙂

    What is the name of the mat you use in the bottom of the pan and how does it work?

    Looks delicious!

  4. Deanna C

    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 🙂

    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!
