Ingredients: Ganache

- 100g white or caramel chocolate chips

- 4 tablespoon peanut butter (caramel peanut butter is the best)

- 1 tablespoon butter

- 1 teaspoon caramel essence

- 2 tablespoon castle milk stout chocolate infused

- 1 tablespoon icing sugar

- 2 heaped tablespoons of heavy cream

Instructions: Brownies

1. Preheat oven to 180°C and grease a square baking tray that's about 22cm x 22cm in size.

2. Mix oil, Castle Milk Stout, sugar and vanilla essence together in a bowl.

3. Once combined mix in 1 egg at a time then add flour and cocoa and whisk until smooth.

4. Add the macadamia nuts and stir through. Pour mixture into your greased baking tray.

5. Bake for 25 minutes - it needs to pull away from the sides of the baking tray but be a little undercooked in the middle.

6. Cool for 10 minutes and remove by tipping over onto a cooling rack.

7. Cut into squares and allow to cool through.
