This whole wheat peanut butter cookie pizza recipe is a fun and delicious treat, and is great for cooking with kids. We’ve made it a few times and have amped up the peanut butter just a touch each time. Now it’s just right and a super fun treat to make and enjoy!
The other day, Ben came up to me and said he wanted to make a cookie pizza – I guess he saw one on TV and was feeling inspired, ha! I thought through what we had in the pantry and knew we could make up something delicious. I used my Captain America chocolate chip cookie cake as inspiration and adapted it majorly to what we had on hand.
What ingredients are used in this cookie cake pizza recipe?
- Butter – you’ll use room temperature for this recipe, salted or unsalted are fine.
- Peanut butter – this is the key ingredient for the peanut butter cookie, of course! I use a natural, no-stir peanut butter, but any one will work, so just pick your favorite brand!
- Granulated sugar – used for sweetness in this recipe.
- Brown sugar – you can use light or dark brown sugar – both will be delicious.
- Egg – one large egg is all you need for this cookie.
- Vanilla extract – vanilla is a key ingredient in all baking recipes. I use a good quality one like this!
- Whole wheat pastry flour – using whole wheat flour makes it feel healthy right, ha! This is my absolute favorite brand.
- Baking soda – a must-have leavening for baking recipes.
- Chocolate candy pieces – You can get creative with this ingredient! We used Reeses pieces, but M&Ms or chocolate chips are other great alternatives.
When Ben and I were making this recipe, we didn’t have chocolate chips, so we made up our version and used Reeses. The best part was that I had to pick them out of a snack mix we had in the pantry.
This recipe is so simple! You know I love cooking with kids, but if you’re new to it, this whole wheat peanut butter cookie pizza is a great place to start cooking with kids because the recipe is flexible, so if those little hands measure ingredients not-so-exactly, it’ll still turn out delicious!
How do I make this cookie pizza?
Preheat oven to 350
In a bowl, combine butter, peanut butter, sugar and brown sugar, mix with a wooden spoon. Add in egg and vanilla extract and stir. Add in whole wheat pastry flour and baking soda and stir to combine, then add in Reese’s pieces and stir to combine.

Want to know the replacement for egg
Sweetphi says
You could use a flax egg which works really well as a replacement for egg in baking. Use 1 tablespoon flaxeed meal mixed with 1 tablespoon water.

Thanks for the Whole Wheat Peanut Butter Cookie Pizza recipe. What size cake pan (8″ or 9″?) works best for this recipe?
Sweetphi says
Both work great, I like to use 8 inch if I want them a little thicker (you might need to add a few minutes to the bake time) or 9 inch is what size is pictured where they’re as picture.
Judy Hoffmann says
