You'll need peanut butter, butter, sugar, eggs, flour, baking soda, and mini peanut butter cups.
Beat butter, peanut butter, and sugar until smooth and fluffy for a soft cookie base.
Combine flour, baking soda, and salt, then slowly mix into the wet ingredients.
Roll dough into small balls and place them in a mini muffin tin for the perfect shape.
Bake at 350°F (175°C) for 8–10 minutes until the edges are slightly golden.
Press a mini peanut butter cup into each warm cookie for a gooey, chocolatey center.
Allow cookies to cool in the pan for a few minutes before transferring to a wire rack.
