Ingredients
2 ½ cups all-purpose flour (spooned & leveled)
2 teaspoons baking soda
¼ teaspoon salt
1 cup unsalted butter, softened
1 cup brown sugar
¾ cup granulated sugar
1 cup creamy peanut butter (not natural)
1 large egg
1 ½ teaspoons vanilla extract
1 ¼ cups Reese’s Pieces, divided
½ cup dark chocolate chunks or chips (optional but recommended)
Instructions
Preheat the oven to 350°F (180°C). Line a baking sheet with parchment paper.
In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.
In a large bowl, cream the softened butter with both sugars until smooth and creamy, about 2–3 minutes.
Mix in the peanut butter until fully incorporated.
Add the egg and vanilla extract, beating until the mixture is smooth.
Add the dry ingredients to the wet ingredients and mix until almost combined—some flour streaks are okay.
Fold in 1 cup Reese’s Pieces and the chocolate chunks, being careful not to overmix.
Scoop 3–4 tablespoon portions of dough and place on the baking sheet, leaving about 2 inches of space. Press a few extra Reese’s Pieces on top.
Bake for 10 minutes, then remove from the oven and bang the tray once or twice to help them spread. Return to the oven for 1–2 more minutes, until edges are lightly golden and centers still look soft.
Let cookies cool on the baking sheet for 10 minutes before transferring to a wire rack. They will set as they cool.
Notes
💡 **Baking Tips**
• Spoon-and-level your flour to avoid dry or cakey cookies.
• Don’t overbake! The centers should look soft—they’ll finish setting as they cool.
• Use creamy (not natural) peanut butter for the softest texture.
• Add extra chocolate chips or peanut butter chips for more flavor.
• Store cookies in an airtight container for up to 4 days, or freeze up to 2 months.
