Thick, chewy and delicious Peanut Butter Cookie Cake is a sweet and salty dream come true. Calling all peanut butter lovers, this quick and easy cake is for you!
This peanut butter cookie cake comes together quickly with mostly pantry ingredients, and it’s so decadent it’s hard to stop at just one slice.
The girls and I have decided that we might just prefer thick, chewy cookie cake over individual cookies. A pretty heart dish never hurts either!
Not only is the consistency great, making each bite like the center of a cookie, but it’s a time saver, too! Since you’re not dropping cookies on multiple cookie sheets, a cookie cake can achieve incredible cookie flavor in much less time.
Cookie cakes are so magical because they are nostalgic and remind us of our childhoods. The love runs deep, and I’m so thrilled to pass this joy along to our kids, too!
I’ve got a cookie cake for every occasion and preference! Don’t miss my Frosted Sugar Cookie Cake, Chocolate Chip Cookie Cake, Funfetti Cookie Cake, Thick and Chewy M&M Cake, and this Incredible Sugar Cookie Cake Recipe.
There’s so much to love about this incredible peanut butter cookie cake! Won’t you join me in the fun?

How to Make Peanut Butter Cake
- Prep – First, preheat oven and grease baking dish.
- Cream – Next, cream peanut butter, butter and sugars until light and fluffy. Incorporate egg and vanilla.
- Combine – Whisk flour, baking powder, baking soda and salt together and gradually blend into wet mixture.
- Bake – Finally, press dough into baking dish, garnish with thick flakes of salt and bake. See baking notes in the printable recipe card.
Tips
- Don’t over-mix! That’s how you achieve the out of this world texture and thickness!
- For a fully baked cookie cake, avoid pressing dough all the way to edges. Dough will spread. This will ensure a smooth, even rise without leaving the center under baked or edges over baked.
- Baking time will vary depending on the pan you use. Reduce baking time for thinner cookie cakes checking in at 15 minutes and increase for thicker cakes if you want them more done.
- When adding dough into the pan, careful to not overfill and factor in 1/3 of dish for the cake to rise.
- Try my super easy buttercream recipe if you’d like to frost your cake.
- Forgot to take out your butter? To soften butter directly from the refrigerator, place the butter unwrapped in the microwave for 10-15 seconds.
- Salt – This Peanut Butter Cookie Cake is especially delicious with a few cracks of sea salt on top served warm with a scoop of vanilla ice cream. In fact, that’s the secret to my incredible peanut butter cookie recipe… sea salt. If you’re a fan of sweet and salty, you can’t miss this step, it’s a game changer!
