Sprinkle Sandwiches

Ingredients:For the Vanilla Bean Marshmallow Frosting:4 egg whites1 cup 200 g superfine sugar1 tablespoon light corn syrupPinch of cream of tartar1 teaspoon pure vanilla extract or vanilla bean pasteFor the Chocolate Coating:8 ounces 240 g best-quality dark or milk chocolate, chopped or callets3 tablespoons 45 ml vegetable oilYou will also need:12 Store-bought ice cream sandwich cookies plus a few extra in case of breakage OR homemade cookies of your choiceSprinkles of your choiceLarge 18" pastry bagLarge plain round pastry tipHow to make it:Make the Vanilla Bean Marshmallow Frosting:Wipe the stainless steel bowl and whisk of an electric mixer with a paper towel dampened with lemon juice to eliminate any trace of grease. Put the egg whites, sugar, corn syrup, cream of tartar in the bowl and put it over a saucepan of barely simmering water (be sure the bottom of the bowl is not touching the water). Whisk constantly but gently until the mixture reaches 130°F (54°C), about 7 minutes depending on the temperature your egg whites were to begin with.Transfer the bowl to the mixer. Beat the mixture on low speed for 2 minutes, then increase the speed to medium and beat for 2 more minutes. Increase the speed to hight and beat until very thick and glossy, about 5 minutes. Add the vanilla bean (or extract) and beat well.This frosting is best used right away, but it will keep covered at room temperature for up to an hour (once it's piped into the cookies it's fine, but just for ideal spreading/piping consistency).Assemble the Marshmallow Sprinkle Sandwiches:Line a baking sheet with wax paper and lay 6 of the cookies inside-up on the wax paper.Fill a large pastry bag fitted with a large plain round tip (I use Ateco ) with the prepared Marshmallow Frosting and pipe a big dollop on top. Place another cookie, right side up, on top and repeat with another dollop and cookie.Make the Chocolate Coating:In a double boiler, or in a microwave-safe bowl, melt the chocolate and oil until smooth, stirring occasionally.Carefully dip one end of each sandwich in the chocolate coating and lay back down on the wax paper. Sprinkle the chocolate areas with your favourite sprinkles, tossing the sprinkles to cover the sides. Let sit to firm up.Once the sandwiches are firmed up, you can transfer them to a plate and collect the remaining sprinkles to put back in their bottles.Best enjoyed right away.
