Ingredients
Ingredient Notes
To make one deep dish peanut butter cookie, you will need:
- Flour: Use all-purpose flour. This recipe has not been tested with any other type of flour.
- Baking soda: This ingredient reacts with the brown sugar and helps the cookie to rise.
- Peanut butter: I recommend using creamy peanut butter.
- Sugar: Granulated sugar and brown sugar add the cookie's wonderful sweet flavor. If you don't have brown sugar on hand, you can easily make homemade brown sugar with just granulated sugar and molasses.
- Egg yolk: 1 egg yolk is all you need to make one extra-large peanut butter cookie. Since this is a recipe for a single peanut butter cookie, using the entire egg will affect the taste and texture of the cookie. Save the egg white and see below for ways we suggest using it so there won't be any waste.
- Butter: I use salted butter in this peanut butter cookie recipe. If you use unsalted butter, add ⅛ teaspoon of salt to your cookie batter.

How To Make A Deep Dish Peanut Butter Cookie
- In a small bowl, mix together the sugars, egg yolk, peanut butter, and melted butter with a spoon.
- Add the flour and baking soda and stir until well mixed.
- Spoon the peanut butter cookie batter into a lightly greased 10-ounce ramekin. Sprinkle granulated sugar over the top and bake in a 350° F (177° C) preheated oven for 12-15 minutes.
Expert Tips
- Read through the entire recipe before starting.
- For this peanut butter cookie I use an 10-ounce ramekin. For best results, use a baking dish of similar size. Many ramekins don’t have the size printed on them. Because of this, it can be hard to know exactly how large (or small) yours is. The best way to measure the size of your ramekin is to fill it with water and pour the water into a measuring cup. To see examples of the baking dishes we use in our recipes, visit our Store Page.
- The peanut butter you use matters. I use creamy brands of peanut butter like Jif, Peter Pan, or Skippy because the creamy texture makes it easier to stir. Creamy peanut butter makes the best chewy peanut butter cookie. If you use natural peanut butter, be aware that this type of peanut butter is mostly made from just crushed peanuts and maybe a little oil. Since it is less smooth than than other peanut butters, the cookie dough will just be less moist and the texture will be different.
- If you want to give your cookie an old-fashioned peanut butter cookie look, use a fork to make a criss-cross pattern over the top of the cookie before baking.
- If your peanut butter cookie is dry, you likely used too much flour. Be sure to measure ingredients correctly. Also, be sure you don't overbake the cookie. Doing so will make the cookie hard.
Frequently Asked Questions
No. Since this is a recipe for a single peanut butter cookie, using the entire egg will affect the taste and texture of the cookie. Save the egg white and see below for ways we suggest using it so there won't be any waste.
Yes, you can! Although I prefer using creamy peanut butter, you can use crunchy instead.
Absolutely! Chocolate and peanut butter are a classic combination. Try adding a tablespoon or two of chocolate chips to this recipe. A little goes a long way.
You will know when the peanut butter cookie is done when the edges of the cookie begin to firm up and brown slightly. This takes between 12-15 minutes.
For best results, use a 10-ounce ramekin that measures 4-inches in diameter and is approximately 1 ¾-inches tall. Many ramekins don’t have the size printed on them. Because of this, it can be hard to know exactly how large (or small) yours is. The best way to measure the size of your ramekin is to fill it with water and pour the water into a measuring cup.

I followed all directions. I did substitute coconut flour for all purpose flour. Cooked for 13 minutes and everything seemed done. Cookie was soft to firm and tasty.
Thanks for the recipe.
Barb says
I made the deep dish peanut butter cookie. It is not cooked in 12 minutes, but is cooked perfectly at 16 minutes. It does taste good though, I will make it again.
Carol Amater says
Hi Joanie
This recipe calls for 3 tablespoons of peanut butter. I use peanut butter powder.
Is the exchange the same: one for one?
Joanie Zisk says
Hi Carol, I haven't tested this recipe with peanut butter powder so I'm not sure how much you would need to use. I believe the powder will have to be reconstituted with water before using.
Stefani says
This was great! However, I'm not sure if something went wrong or if the texture is supposed to be that way, but after cooking it for 10 minutes, the cookie had a strange dough-y texture to it. It was cooked, though, so I ate it. The taste was delicious, I just wasn't a big fan of the texture! 🙂
J. Hegyi says
Great recipe.
