Ingredients

Scale
  • 1 unbaked 9-inch pie crust (homemade or store-bought)
  • 3/4 cup creamy peanut butter
  • 3/4 cup semi-sweet chocolate chips
  • 1 cup light brown sugar, packed
  • 2/3 cup rolled oats (old-fashioned oats preferred)
  • 3 large eggs, room temperature
  • 1/2 cup unsalted butter, melted and cooled slightly
  • 1/4 cup whole milk
  • 1 1/2 teaspoons pure vanilla extract
  • 1/2 teaspoon salt
  • Optional: extra chocolate chips or chopped peanuts for topping
  • Optional: sea salt flakes for topping

Instructions

  1. Preheat your oven to 350°F (175°C). Place the unbaked 9-inch pie crust into a pie plate and crimp the edges as desired. If using a store-bought crust, thaw according to package instructions.
  2. In a small bowl, melt the butter and set aside to cool slightly.
  3. In a large mixing bowl, whisk together the eggs and brown sugar until smooth and slightly frothy, about 1 minute. Add the melted butter, milk, and vanilla extract. Whisk until completely combined.
  4. If the peanut butter is stiff, microwave it for 15-20 seconds until just softened. Add the peanut butter to the bowl and stir until well blended and no lumps remain.
  5. Stir in the rolled oats and salt until evenly distributed.
  6. Fold in the chocolate chips with a spatula.
  7. Pour the filling into the prepared pie crust and smooth the top. Sprinkle extra chocolate chips or chopped peanuts on top if desired.
  8. Place the pie on a baking sheet and bake at 350°F (175°C) for 35-45 minutes. The edges should be golden and set, while the center will look slightly wobbly but not liquid. Tent with foil if the edges brown too quickly.
  9. Check for doneness by inserting a toothpick 2 inches from the edge; it should come out mostly clean.
  10. Cool the pie on a rack for at least 2 hours before slicing to allow the filling to set.
  11. Serve as-is or with whipped cream, vanilla ice cream, and a sprinkle of sea salt flakes if desired.

Notes

For gluten-free, use a gluten-free pie crust and certified gluten-free oats. For dairy-free, substitute vegan butter, dairy-free chocolate chips, and plant-based milk. Do not overbake; the center should be slightly wobbly when removed from the oven. Let the pie cool completely for clean slices. Store leftovers tightly covered at room temperature for 2 days or in the refrigerator for up to 5 days. Pie can be frozen for up to 2 months.
