Dark Chocolate and Dulcey de Leche Cupcake by Steve Penny

Ingredients (10-12 cupcakes):

250g   Softened butter

150g   Caster sugar

100g   Light brown sugar

250g   Eggs

20ml   Milk

250g   Self-raising flour

30g     Cocoa powder

20g     Cocoa nibs

2 cans Condensed milk

100g   Dulcey de leche

Valrhona Dulcey pearls

Chocolate Butter Cream:

50g Dark chocolate (minimum 70% cocoa solids)

100g Unsalted butter, softened

200g Icing sugar

1 tsp Vanilla extract

Splash of Milk (to loosen)


To make the Dulcey de Leche:

Step 1: Take two cans of condensed milk and place them unopened in a bain-marie in the oven. Set the oven temperature to 120 degrees for around 2-3 hours. Be careful when opening the cans as they will remain hot for a long time!

To make Chocolate Butter Cream:

Step 1: Melt the chocolate in a bowl set over a pan of simmering water. Allow to cool until the chocolate no longer feels hot to the touch.

Step 2: Beat the butter in a second bowl until soft then gradually add the icing sugar. Add the vanilla extract and beat again.

Step 3: Add the melted chocolate to the butter mixture until completely mixed, you can add a few drops of milk if the mixture is a little stiff.

To make the Cupcakes:

Step 1: In a bowl mix together the flour, cocoa and cocoa nibs.

Step 2: Cream the butter and sugars together until light and fluffy.

Step 3: Slowly add the milk, eggs and lastly the dried ingredients (flour, cocoa and cocoa nibs). Fold in the Dulcey de Leche into the mix.

Step 4: Fill 10-12 muffin tins. Don’t fill to the top, only ¾ of the cases should be full!

Step 5: Bake at 180 degrees for approximately 15-20 minutes (or until a knife inserted into one of the cakes comes out clean) and allow to cool.

Step 6: Once cool, carefully make a hole in the top of the cakes using a teaspoon and pipe in the dulcey de leche. Top with a spread of the milk chocolate butter cream to give a smooth velvety finish.

Step 7: Sprinkle Valrhona Dulcey pearls and drizzle more chocolate on top just for luck!
