BEST EVER Stuffed Peanut Butter Cookies

Divide the mixture into eight equal pieces that are approximately 1 Tablespoon each. Roll each piece into a ball and place the balls in the freezer for 15 minutes to chill. 

While the balls are chilling, combine the remaining 1/2 cup of peanut in a mixing bowl with the softened butter, brown sugar and granulated sugar. Mix together on medium speed with a hand mixer or a stand mixer for 2-3 minutes until light and fluffy.

Add in the egg and vanilla and mix on medium speed until combined, scraping down the sides of the bowl half way through. 

In a separate bowl, combine the flour, cornstarch, baking soda, and salt and whisk to combine and remove any lumps. 

While mixing on low speed, slowly add the dry ingredients to the peanut butter sugar mixture until they are just combined. Scrape down the sides of the bowl and continue to mix until everything is well combined. The dough will be thick and the consistency of playdough.

Divide the cookie dough into eight equal pieces that are approximately 1/3 cup each and then flatten them into discs. 

Remove the peanut butter balls from the freezer and place one of the balls in the middle of each flattened disc. Shape the discs of dough around the peanut butter balls to enclose them completely. Place the cookie dough balls in the freezer to chill for 15 minutes.

While the dough is chilling, preheat the oven to 350˚ and line a sheet pan with parchment paper.

Remove the cookie dough balls from the freezer and place them on the prepared cookie sheet. Bake for 13-15 minutes until the edges of the cookies just barely turn brown.

Remove the cookies from the oven and allow to cool for 3-5 minutes before serving.
