Ingredient Notes
See recipe box below for ingredient amounts and full recipe instructions.
- Flour: Use all-purpose flour.
- Baking powder: Helps the cookie rise.
- Peanut butter: I recommend using creamy peanut butter.
- Brown sugar: For sweetness. 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 a single cookie. See below for ways to use leftover ingredients, including the egg white.
How To Make This Recipe
Just mix the ingredients together in one bowl and pour the cookie batter into an oven-safe ramekin to bake for 8 minutes.

Expert Tips
- For this peanut butter cookie I use an 8.5-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.
Frequently Asked Questions
No, the texture of the cookie will be off if you use the entire egg. Use just the yolk and save the white. See below for ways to use up the leftover egg white.
Yes you can! I really do prefer using creamy peanut butter in my peanut butter cookies but you can use crunchy instead.
Absolutely! Chocolate and peanut butter is a classic combination. Try adding a tablespoon or two of chocolate chips to this recipe. A little goes a long way.

Never evoled into a cookie. Just hot cookie dough. I could have continue to cook but dought eas awesome.
I made the deep dish peanut butter cookie. It is not cooked in 8 minutes, but is cooked perfectly at 16 minutes. It does taste good though, I will make it again.
Hi Joanie
This recipe calls for 3 tablespoons of peanut butter. I use peanut butter powder.
Is the exchange the same: one for one?
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.
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! 🙂
