Here's a low-carb version of the wildly popular 5-pound Costco Peanut butter pie! It features a honey graham crust, peanut butter pie filling, and a velvety chocolate mousse topping. This pie is a must-try!
Put the cream cheese and granular sweetener in a large mixing bowl. Use a stand or hand mixer on medium speed to beat until fluffy. With the mixer still on medium speed, mix in the peanut butter until smooth.
Pour the cream and vanilla into a medium mixing bowl. Use the mixer on medium speed to whip until stiff peaks form. Fold the whipped cream into the peanut butter mixture until thoroughly combined.
Reserve 1 cup of the peanut butter filling for the top of the pie, and put it in the refrigerator until ready to use. Spread the rest of the peanut butter filling evenly into the prepared pie crust. Cover and refrigerate this layer for at least one hour.
Prepare the Chocolate Mousse
Put the chocolate chips into a medium bowl. Bring the cream to a simmer in a small saucepan over low heat. Pour the cream over the chocolate chips. Allow to sit for a few minutes until the chocolate melts, then whisk until smooth. Allow it to completely cool.
Pour the cream and vanilla into a medium mixing bowl. Use the mixer on medium speed to whip until stiff peaks form. Place the whipped cream in the refrigerator until the chocolate has cooled.
Use a silicone spatula to fold the whipped cream into the melted chocolate. Gently lift and fold until the mousse is thoroughly combined. Be careful not to overmix.
Assemble the pie
Evenly spread the mousse over top of the peanut butter layer.
Place the remaining peanut butter filling in a piping bag fitted with a star tip. Pipe the filling a round the border of the pie.
Refrigerate uncovered until the filling is set. Cover the pid and refrigerate at least 4 hours before serving. Overnight is even better!

The heavy cream can be heated in the microwave in 20-second increments for the mousse layer until simmering.
This recipe has a lot of whipped cream in it. Homemade is best, but you can substitute Keto Truwhip or Cool Whip for the whipped cream. This will change the nutritional values.
