Ingredients

  • ½ cup unsalted butter softened
  • ¾ cup creamy peanut butter
  • ¾ cup light brown sugar
  • ¼ cup granulated sugar
  • 1 large egg
  • 1 egg yolk i.e. you will be using 1 whole egg + 1 extra egg yolk
  • 1 teaspoon vanilla extract
  • ½ teaspoon baking soda
  • ¼ teaspoon salt
  • 1 tablespoon cornstarch
  • 1 ½ cups all-purpose flour
  • 12 Reese'e Eggs you can also make these with regular peanut butter cups

Instructions

  • Preheat oven to 350ºF. While preheating, be sure to read tips & tricks in post above for recipe success.
  • In a medium-sized mixing bowl, beat the peanut butter (¾ cup) and softened unsalted butter (½ cup, i.e. 1 stick) on medium speed for 20-30 seconds until combined.
  • Add in the light brown sugar (¾ cup) and granulated sugar (¼ cup) and continue beating on medium for another 20-30 seconds until creamy. Do not overmix.
  • While the mixer is on low, add in the egg (1 large), extra egg yolk (1 large), vanilla extract (1 teaspoon), baking soda (½ teaspoon), salt (¼ teaspoon), and cornstarch (1 tablespoon). Stir until combined. Slowly add all-purpose flour (1 ½ cups) and mix until just incorporated.
  • Grease and line a 9×13 light-colored metal pan with parchment paper (I like to create a parchment sling, as shown in photos above, so I can lift the bars out of the pan to cut). Spread dough into an even layer in pan. 
  • Press on 12 Reese's Eggs. You want to press them into the dough (so half the egg is covered) but be careful not to press too hard or they'll break.
  • Bake for 14-16 minutes at 350℉ or until edges are lightly brown and the center no longer looks wet. Allow the bars to cool for up to 30 minutes before cutting.

Notes

Storage: Store in an airtight container for up to 5 days (although they're best within 3 days for ultra softness!).
Freezing: Store in an airtight container or freezer ziploc bag for up to 1 month. For optimal freshness, I recommend wrapping the individual bars in plastic wrap before placing in container.
