125g (1 cup) flour
1 tsp baking powder
1/4 tsp salt
113g (1/2 cup) unsalted butter, room temperature
50g (1/4 cup) sugar
1/2 cup unsalted butter, cut into pieces
1/2 cup sugar
2 tbsp light corn syrup
1 (14 oz) can sweetened condensed milk
3.5 oz / 100g milk or semisweet chocolate, finely chopped
1/2 tsp light corn syrup
30g (2 tbsp) 1/4 cup unsalted butter, cut into pieces
How to make it :
1) Preheat oven to 160C / 325F. Line a 20 x 20 / 8 x 8 inch baking pan with parchment paper. In a small bowl, combine together flour, baking powder and salt. Set aside. In a large bowl, combine together butter and sugar and beat with a mixer until light and fluffy. Stir in the flour mixture and mix just until incorporated. Spread into the pan and bake for 15-18 minutes or until lightly golden brown. Let cool completely.
2) To make the filling, combine together butter, sugar, corn syrup and condensed milk in a saucepan. Heat, stirring occasionally, until the butter in melted and the mixture looks smooth. Bring to boil and cook over low heat, stirring constantly, until the mixture thickens a bit and turns amber color. Spread onto the shortbread layer and let cool completely. Transfer into the fridge for a few hours or overnight.
2) To make the chocolate glaze, combine together butter and corn syrup in a small saucepan and heat until the butter is melted. Remove from heat, add chocolate and stir until melted. Pour over the condensed milk layer immediately. Cool completely before cutting into squares. For the best results, slice only after chilling for a few hours.
