Method

For the brownies

Preheat oven to 175 degrees. Butter a 9-inch square baking pan. Line with parchment, leaving a 2-inch overhang on two sides; butter parchment.

In a medium bowl, whisk together flour, baking powder, and salt.

In a heatproof bowl set over a pot of simmering water, melt chocolate and butter with oil. Remove from heat. Add both sugars and whisk 10 seconds. Add eggs and whisk vigorously until glossy and smooth, 45 seconds. Using a rubber spatula, stir in dry ingredients. Pour batter evenly into prepared pan, smoothing top with spatula.

Bake until set and a tester inserted in center comes out with moist crumbs, 35 to 40 minutes. Let cool in pan on a wire rack 20 minutes, then remove using parchment; let cool completely on rack before cutting into squares. Brownies can be stored in an airtight container up to 2 days.

For the white chocolate frosting

Microwave chocolate with 1/4 milk in microwavable bowl on medium-high for 1-2 minutes; stir chocolate halfway during cooking time. Do not overheat. Chocolate will continue to melt while being stirred.
Cream butter and shortening with electric mixer. Add vanilla.

Gradually add sugar, one cup at time, beating well on medium speed. Scrape sides and bottom of bowl often.
When all sugar has been mixed in, icing will appear dry

Add remaining milk and beat at medium speed until light and fluffy. Beat in chocolate mixture.

For the chilli chocolate truffles

Break the chocolate into little chunks and place in a small bowl. In a saucepan, bring the cream to the boil, add the butter and take off the heat. Pour the cream over the chocolate chunks and leave to stand for a few minutes, giving the chocolate a chance to melt.
Stir the mixture and leave for another few minutes. Stir it again to make sure it’s mixed thoroughly, then cover and refrigerate for at least 2 hours or until set.
Toast the hazelnuts, bash them up into fine bits and place them in a shallow bowl. Place the cocoa in another shallow bowl. With a teaspoon, scoop out little balls of the set truffle mixture. Roll in the palm of your hand, then roll in either the cocoa or bashed up hazelnuts to coat.
Place them in the fridge to firm up for about half an hour before serving them

Building of plate

Cut the brownie in rectangles or square and place in middle of plate. Place chocolate frosting in piping bag and cut small hole. Carefully add 4 or 5 dots of frosting along the brownie and around the plate as you prefer. Place 2 or 3 truffles on side of brownie and dig in.
