Fudge Cake - cooking recipe

Ingredients

2/3 cup flour
1/2 tsp baking powder
1/4 tsp salt
3 tbsp unsweetened cocoa powder
2 None eggs
1/2 cup granulated sugar
1 tsp vanilla extract
4 tbsp (1/2 stick) butter, melted
3/4 cup walnuts, chopped
None None FOR THE FUDGE ICING
1 cup firmly packed light brown sugar
3 tbsp milk
3 tbsp butter
1 oz semi-sweet chocolate, chopped
1/4 tsp peppermint extract (optional)

Preparation

Preheat the oven to 350\u00b0F. Grease and line an 8-inch square baking pan with parchment paper, extending the paper over 2 opposite sides for handles.
Sift flour, baking powder, salt and cocoa powder into a medium bowl. Beat the eggs in a large bowl with an electric mixer until fluffy. Gradually beat in the granulated sugar, then add the vanilla.
Using a large metal spoon, fold in the flour mixture, then the melted butter and chopped walnuts. Pour into the prepared pan, smoothing the top.
Bake for exactly 15 mins (this ensures a nicely soft center). Cool in pan on a wire rack for 20 mins, or until almost cool.
For the icing, place the brown sugar, milk and butter in a medium, heavy-bottomed saucepan. Bring to a boil, stirring constantly with a wooden spoon. Simmer for 3 mins. Remove from the heat. Stir in the chocolate and peppermint extract, if using.
Stir the icing with the wooden spoon for 1-2 mins, until the fudge begins to thicken. Quickly pour onto the cake and spread with a spatula. It will begin to set immediately. Let stand until the icing is firm, but still warm. Lift the cake onto a cutting board. Cut into small squares.
