Stonyfield Organic Yogurt, and this pie is fabulous. I find a lot of recipes on the back of cartons and boxes, but I also scour company and association websites. This recipe is from the Stonyfield site. Have a look. I'm sure you'll find lots of other recipes you'll want to try. I adapted the recipe a bit, and it came out great! I just love peanut butter and chocolate!
Peanut Butter Chocolate Pie
1 cup creamy peanut butter
1/2 cup Oikos Plain Greek Yogurt (it's a staple in my refrigerator-Oikos is a Stonyfield line-original recipe called for a 1/2 cup Stonyfield lowfat vanilla yogurt)
1/3 cup sweetened condensed milk
1 1/2 cup heavy cream
6 oz-- about 2 1/2 bars--Madecasse 67% Smooth Sambirano Valley Madagascar chocolate because the original recipe called for a bag of milk chocolate chips but there was no size. Break the chocolate into pieces
Chocolate cookie crust (Original recipe called for graham cracker crust) but I can never have too much chocolate
Chocolate shavings for topping
In a chilled bowl, whip 1 cup of the heavy cream until it forms soft peaks.
Melt chocolate and add 1/2 cup of whipped cream and mix well.
Spread the chocolate mixture over the bottom and up the sides of the crust and refrigerate until set.
In a food processor, blend peanut butter, yogurt and sweetened condensed milk.
Add the remaining whipped cream and mix well.
Pour into the crust and refrigerate overnight (or until set, about 2 hours).
When ready to serve, whip the remaining heavy cream and top each slice with a dollop of whipped cream and sprinkle with chocolate shavings.
