Variations for Reeses pieces cookies

Cookie sandwiches-Put filling between the two cookies and you’ve got yourself a delicious dessert! I suggest using classic vanilla frosting  but you can also use your favorite ice cream, frosting, pudding, or nut butter. Some other frostings you can try are Peanut Butter Frosting (4 Ingredients) or Chocolate Cream Cheese Frosting or Marshmallow Frosting or the classic Chocolate Buttercream Frosting.

Try another cake mix flavor- You can really change things up by exchanging the chocolate cake mix for yellow, vanilla, German chocolate, or Devil’s food cake mix. Depending on what mix-ins you choose, you may even want to try lemon, red velvet, pineapple, or strawberry mixes!

Stuffed Cookies– Before cooking, place a yummy surprise in the middle of the chocolate dough ball and cover it back up. Try little chocolate candies, caramels, or mini Reese’s Peanut Butter Cups.

Dip them- After the cookies are baked and cooled, dip half the cookie in dark, milk, or white melted chocolate. Let the chocolate set and enjoy!

Roll- Before baking, roll the cookie dough balls in powdered sugar, granulated sugar, or cocoa powder to take them up a notch.

Tips and Techniques for Reeses peanut butter cookies

Why did my cookies spread? Why are my cookies flat?– You may have forgotten to chill the dough or there may be too much oil. Be sure to chill the dough and measure ingredients correctly.

Why are my cookies dry?– It is possible there was not enough oil in the dough or maybe you needed larger eggs. You can add a bit of liquid, such as water, milk, or oil to get the right consistency.

How to keep homemade cookies soft?– A simple, yet great way to keep your cookies soft is to put a slice of bread in the cookie jar with the cookies. The next day, the bread will be dry and its moisture would have transferred over to the cookies.

You must chill dough- Otherwise your cookies will spread and be flat.

Make even cookie dough balls– Ensures all cookies are same size so that they cook evenly.

Butter vs. Oil-You can use either, but I suggest oil, because it gives a better texture and will stay moist for longer. If you are using butter, make sure it is unsalted to prevent cookies from becoming too salty.

Line baking tray with parchment paper– Because this prevents cookies from sticking to the pan and also makes for easier clean up.

Eggs should be at room temperature- Because they blend together smoothly and evenly.

Don’t over-mix dough– Because it makes tough cookies.

Don’t over-bake cookies– Because they become dry and hard.


Room temperature– Unfrosted cookies can be stored in a sealed container at room temperature for up to 3 days.

Refrigerator– Leftovers can be stored in a sealed container for up to 5 days.

Make ahead instructions– You can store cookie dough in a sealed container in the freezer for up to 1 month. When you are ready to enjoy these cookies, thaw in fridge overnight and make cookie balls and bake as per instructions below.
