My step-grandma used to make this for us kids, when we were growing up. After I moved away, I tried many, many times to recreate the recipe, with no luck. I was thrilled to find it by chance in a book called “Company’s Coming – Most Loved Treats” by Jean Pare. Most-loved indeed! Now I make them every Christmas. Well, every Christmas except the one Christmas immediately after the twins were born! If you look them up in the book, they are actually called Pinwheels.
2 ½ cups confectioner’s sugar
1/3 cup mashed potatoes
½ teaspoon vanilla
1/8 teaspoon salt
1/3 cup smooth peanut butter
Combine the first four ingredients in a large bowl. Turn out onto a work surface dusted with confectioner’s (powdered) sugar. Knead until smooth, adding more powdered sugar as needed, until a pliable but not sticky dough forms. Divide into 3 equal portions. Roll out 1 portion on the surface dusted with powdered sugar, to 5×8 inch rectangle, 1/8 inch thick.
Spread about 1 ½ tablespoons peanut butter evenly over the top. Roll up, jelly-roll style, from long side. Wrap with plastic wrap. Chill. Repeat with remaining portions. Cut each roll in to ¼ inch slices. Makes about 6 dozen pinwheels.
