Packed with marshmallows, chocolate and peanut butter, these Gooey Ritz Peanut Butter Cup S’mores Bars are out of this world! This easy cake mix cookie bar recipe is perfect for every occasion.
You guys know how I am obsessed with Ritz Peanut Butter Cup S’mores! It is seriously the best way to do s’mores: salty and sweet with chocolate AND peanut butter. :) I wanted to incorporate those flavors into a fun, gooey, marshmallow-y cake bar. I am in love with how these turned out!! Kevin is obsessed with them! He has declared it one of his all time favorite treats ever.
The bottom layer is a sweet, buttery cake, topped with a layer of salty Ritz crackers and fluffy marshmallow creme.
They’re then topped off with mini peanut butter cups and crushed Ritz crackers for the perfect combo of salty, sweet, ooey, and gooey!!! :) You’ve got to make these bars! :)
Here’s all you need to make these bad boys.
How to Make Peanut Butter S’mores Bars
First beat together 1 yellow cake mix, 1 stick softened butter, and 1 egg into a firm dough.
Then press into the bottom of a 9×13 pan that’s been lined with foil. Lining makes it so much easier to get them out of the pan!
Here’s my trick for a faster and easier way to line a pan with foil. Press foil around the bottom of the pan first, then place inside. It should fit perfectly now!
Next add a layer of Ritz crackers…
Then mix together 1 jar of marshmallow creme with 1 can of sweetened condensed milk. The sweetened condensed milk gives the marshmallow fluff a wonderful toasty flavor! :)
And pour evenly over the crackers for your sweet marshmallow filling.
Top with 2 bags mini peanut butter cups and more crushed Ritz.
Bake at 350 degrees F for 20-25 minutes. Allow to cool completely in pan before cutting and serving. Bars will be very gooey when warm, but will set up once cooled. You can speed up this process by putting them in the fridge. Kevin actually prefers them chilled!
Oh my gosh, you guys. These bars.
They’re sweet, buttery, fluffy, chocolaty, and peanut buttery.
Cannot get over how soft and gooey they are!! :) Love them!! :) If you’re a fan of cake, Ritz crackers, and peanut butter cups, you’ve got to make these bars happen ASAP. :) Hope you enjoy!! :)
