Using mini Reeses peanut butter cups & adorable heart sprinkles, these cookies are perfect for office Valentines treats, school parties, or just as a fun baking activity to make with the kids!
In a large bowl, cream together 6 tablespoons unsalted butter, softened, ½ cup creamy peanut butter, ½ cup brown sugar, and ½ cup granulated sugar with an electric mixer on medium speed for 30 seconds. Add in ½ teaspoon vanilla extract and 1 large egg and continue to mix for 10 seconds.
Add ¾ teaspoons baking soda and mix on low speed for 10 seconds. Add 1 ¼ cups all-purpose flour and continue to mix until all flour is incorporated.
Scoop & roll dough into 1 tablespoon sized balls and place each in a greased, mini muffin tin.
Bake at 350℉ for 8 minutes. Remove from oven, and immediately press one mini Reeses peanut butter cup into the center of each cookie.
After a few minutes, the chocolate of the peanut butter cup will start to melt. Once this happens, gently place a heart sprinkle onto the top of each one.
Place pan in refrigerator for 10-15 minutes to help the chocolate re-harden.
Allow to cool before removing from the cookies from the pan. For easy removal, use the tip of a spoon to help lift out the cookies.
If not serving immediately, store in an airtight container for up to 5 days or freeze for long-term storing.
