One of Canada's favorite confections and our daughter's too! I will be making these for Christmas this year.
Butter (or use a cooking spray) a 9 x 9 inch (23 x 23 cm) pan.
1/2 cup (1 stick) (113 grams) unsalted butter, room temperature
1/4 cup (50 grams) granulated white sugar
1/3 cup (30 grams) unsweetened cocoa
1 large egg, beaten
1 teaspoon pure vanilla extract
2 cups (200 grams) graham cracker crumbs
1 cup (65 grams) coconut (either sweetened or unsweetened)
1/4 cup (56 grams) unsalted butter, room temperature
2 - 3 tablespoons milk or cream
2 tablespoons vanilla custard powder (Bird's) or vanilla pudding powder
1/2 teaspoon pure vanilla extract
2 cups (230 grams) powdered sugar (confectioners or icing) sugar
4 ounces (115 grams) semisweet chocolate, chopped
1 tablespoon (14 grams) unsalted butter
BOTTOM LAYER: In a saucepan over low heat, melt the butter. Stir in the sugar and cocoa powder and then gradually whisk in the beaten egg. Cook, stirring constantly, until the mixture thickens (1 - 2 minutes). Remove from heat and stir in the vanilla extract, graham cracker crumbs, coconut, and chopped nuts. Press the mixture evenly into the prepared pan. Cover and refrigerate until firm (about an hour).
FILLING: In your electric mixer cream the butter. Beat in the remaining ingredients. If the mixture is too thick to spread, add a little more milk. Spread the filling over the bottom layer, cover, and refrigerate until firm (about 30 minutes).
TOP LAYER: In a heatproof bowl over a saucepan of simmering water, melt the chocolate and butter. Spread over the filling and refrigerate.
TO SERVE: To prevent the chocolate from cracking, using a sharp knife, bring the squares to room temperature before cutting.
Yield: Makes about 25 squares
