Ingredients

ingredients needed to make a deep dish peanut butter cookie on a wooden counter.
  • Flour: Stick with all-purpose flour for this recipe. It hasn’t been tested with alternative flours, so results may vary.
  • Baking soda: Essential for leavening, baking soda interacts with brown sugar to give your cookie that ideal lift.
  • Peanut butter: Creamy peanut butter is the go-to for this recipe, delivering a smooth and rich texture.
  • Sugar: A mix of granulated and brown sugar elevates the cookie’s flavor. The molasses in brown sugar adds depth and complexity. If you don’t have brown sugar, consider using our small batch brown sugar recipe.
  • Egg yolk: One egg yolk is all it takes to make a single, large peanut butter cookie. Using a whole egg could alter the cookie’s taste and texture. Don’t toss the egg white, save it to use in one of our egg white recipes like Flourless Chocolate Cookies or Two Chocolate Cupcakes.
  • Butter: Salted butter is preferred in this recipe. If you opt for unsalted butter, add an extra 1/8 teaspoon of salt to your cookie dough.

This is just an overview of the ingredients I used and why I used them. For the full recipe please scroll down to the recipe box at the bottom of the post.

Expert Tips

  • Before you start cooking, make sure to read the entire recipe, including the Ingredient Notes section, and examine the process photos. This detailed guide will help you understand how the recipe unfolds, ensuring your peanut butter cookie turns out perfect every time. All the information you need is found within the body of this recipe post, so don’t miss a thing!
  • Ramekin Size Matters: For the perfect single serving peanut butter cookie, aim to use a 10-ounce ramekin. Unsure of your ramekin’s size? Fill it with water and pour the water into a measuring cup to determine its volume.
  • Choose Your Peanut Butter Wisely: The brand and type of peanut butter make a difference. Creamy options like Jif, Peter Pan, or Skippy yield a smoother, chewier cookie. Natural peanut butters will result in a drier, differently-textured cookie.
  • Classic Cookie Look: To give your cookie that traditional peanut butter cookie appearance, use a fork to make a criss-cross pattern on the top of the dough before baking.
  • Avoid Dryness: If your cookie turns out dry, double-check your measurements, especially for the flour. Overbaking could also be the culprit, so keep an eye on that timer to ensure a perfectly textured cookie.

Serving Suggestions

This deep dish peanut butter cookie is divine on its own, but here are a few extras that can make it even more indulgent:

  • Top with a scoop of your favorite vanilla ice cream.
  • Drizzle with chocolate sauce for a delightful flavor pairing.
  • Sprinkle chopped peanuts on top for added texture.
  • Serve with a glass of cold milk on the side.

Frequently Asked Questions

Can I use the whole egg in this recipe?

No, it’s essential to only use the egg yolk for this single serve peanut butter cookie. Using the entire egg will alter the flavor and texture. Don’t worry, you can repurpose the egg white in other recipes.

Can I use crunchy peanut butter in this single serve peanut butter cookie recipe?

Certainly! While I favor creamy peanut butter for a smoother texture, crunchy works just as well if you prefer some extra crunch.

Can I add chocolate chips to this peanut butter cookie recipe?

Absolutely, a tablespoon or two of chocolate chips complements the peanut butter flavor perfectly. A small amount can make a big difference.

How can I tell when my single serve cookie is done?

Your cookie is done when the edges start to firm up and slightly brown. This usually happens between 12-15 minutes of baking time.

What size ramekin should I use?

Aim for a 10-ounce ramekin measuring around 4 inches in diameter and 1 ¾ inches in height. If the size isn’t indicated on your ramekin, fill it with water and pour it into a measuring cup to determine its volume.

Can I double this peanut butter cookie recipe?

Absolutely, just double the ingredients and divide the cookie dough between two 10-ounce ramekins.

Can I bake this peanut butter cookie in a microwave?

While microwaving is an option, note that the texture and taste may not be as delightful as when baked in an oven.
