Key Ingredients

Complete list of ingredients and amounts can be found in the recipe card below.

Peanut Butter: You can’t make peanut butter cookies without it! Use creamy peanut butter for this recipe rather than crunchy. Butter, Brown Sugar, Granulated Sugar: The beginning of our cookie dough comes from creaming these ingredients together. A combination of both white and brown sugar gives these cookies the perfect chewiness. Remember to lightly pack the brown sugar when measuring. Egg: You just need one large egg to make these cookies. Let the eggs and butter come to room temperature before mixing the dough. Vanilla Extract: Always use a good quality pure vanilla extract when baking. Milk: A small amount of milk, cream, or half and half adds needed moisture to the dough. Flour, Baking Soda, and Salt: The basic dry ingredients for most cookie recipes. Mini Reese’s Cups: You’ll need 36 miniature Reeses cups to make this recipe. 

How to Make Peanut Butter Cup Cookies

Success Tips

These cookies are truly super easy to make, and almost fail-proof, but here are a few tips to help. 

Don’t Wait: You need to add the peanut butter cups to the cookies as soon as they come out of the oven, otherwise, they won’t go in. Spray the Pan: Even if your mini muffin pan is coated with non-stick material, you should still spray it well. There’s nothing worse than having your peanut butter cup cookies stuck in the muffin tin. 

Having the right tools in the kitchen makes cooking and baking so much more fun. Here are the tools I use to make these cookies: 

KitchenAid Hand Mixer: Kitchenaid makes some of the best small appliances. I love this mixer specifically because it has 9 different speeds. Unlike others that I’ve used, this one has the ability to mix things at a speed that is actually very low when I need it to!Wilton Muffin Pan: This mini muffin pan has 24 spaces, so I do this recipe in two batches. It’s non-stick and cleans up very easily which is a plus.Cookie Scoop: To get evenly sized cookies, I love using a cookie scoop. They come in different sizes, and for this recipe, I used the smaller, 1 tablespoon size.
