1. Prepare the Filling Base:
- Ensure your cream cheese is fully softened to room temperature for easy, smooth mixing. Ensure your frozen whipped topping is fully thawed in the refrigerator.
- In a large mixing bowl, combine the softened cream cheese and the confectioners’ sugar.
- Beat with an electric mixer (handheld or stand mixer with paddle attachment) on medium speed until the mixture is completely smooth and creamy, with no lumps of cream cheese remaining. Scrape down the sides of the bowl as needed.
2. Add Peanut Butter and Milk:
- Add the 1 cup of creamy peanut butter and the 1 cup of milk to the cream cheese mixture in the bowl.
- Continue to beat with the electric mixer on medium speed until the peanut butter and milk are fully incorporated and the mixture is smooth. Scrape down the sides of the bowl again to ensure everything is well combined.
3. Fold in Whipped Topping:
- Add the thawed frozen whipped topping to the peanut butter mixture.
- Using a rubber spatula, gently fold the whipped topping into the peanut butter base until it is evenly incorporated and the mixture is light and fluffy. Try not to overmix or deflate the whipped topping too much.
4. Assemble the Pies:
- Divide the prepared peanut butter filling mixture evenly between the two pre-made graham cracker crusts.
- Spoon the mixture into each crust and use your spatula to spread it out smoothly and evenly.
5. Cover and Freeze:
- Cover each pie carefully with plastic wrap (try not to let it touch the surface of the filling if possible) or the plastic dome lid that often comes with pre-made crusts.
- Place the pies in the freezer. Freeze until firm, which will take at least 4-6 hours, but overnight is even better for a solid set, especially if you plan to slice neatly.
6. Serve:
- When ready to serve, remove the pie(s) from the freezer. If frozen very solid, you may want to let it sit at room temperature for 5-10 minutes to soften just slightly for easier slicing.
- Slice the frozen No-Bake Peanut Butter Pie into wedges using a sharp knife (dipping the knife in hot water and wiping clean between cuts can help).
- Serve immediately. Enjoy this cool, creamy, peanut buttery delight!
