Chocolate Mint Squares

This recipe comes from my mother, Margie Heard, and her copy of it was 30 years old and pretty much illegible (which she said, "makes the challenge all the more fun!") It's a family favourite  and today we experimented with a gluten-free option.

1 cup chocolate mint chocolate chips
1/2 cup butter
1/4 cup icing sugar
1 egg, beaten
2 cups of graham cracker crumbs (gluten-free optional)
2 cups icing sugar
2 Tbsp milk

In a small saucepan, melt the chocolate chips, and 1/4 cup of the butter. Once melted, remove 1/4 cup of this mixture and set aside. To the remainder in the saucepan, add 1/4 cup of icing sugar and the egg. Stir this together and once combined, add the graham cracker crumbs. Mix thoroughly. This should be thick enough that it makes almost a ball of dough. Put this into an 8inch pan and spread flat. Place pan in fridge to chill.

In another bowl, add the remaining 1/4 cup softened butter to 2 cups of icing sugar and the milk. Using an electric beater, mix this until it is smooth. Spread over the chocolate and graham crust. On top of this you add the reserved chocolate mix from earlier and refrigerate for 2 hours before serving.

Optional: You can add green food colouring to the icing sugar but we opted out.
