BROOKIES RECIPES

Steps:

• Butter a 23cm square cake tin and line with baking parchment. Heat the oven to 180C/160C fan/gas 4. First, make the cookie layer. Put the butter and both sugars in a bowl and beat with an electric whisk until just combined. Alternatively, do this in a stand mixer. Add the whole egg and egg yolk, and beat again until combined. Mix in the flour, ¼ tsp salt, the bicarbonate of soda and chocolate chunks. Press the cookie dough into the base of the prepared tin using the back of a spoon, then chill for 30 mins.
• For the brownie layer, melt the butter and chocolate in a heatproof bowl over a pan of just simmering water, stirring until smooth and combined. Leave to cool slightly, about 10 mins. Whisk the eggs, vanilla and sugar together in a large bowl with an electric whisk until slightly thickened, about 3 mins. Fold the cooled chocolate and butter mixture through the beaten eggs with a large spoon until well combined.
• Fold the buttery chocolate mixture, cocoa and flour together to combine. Spoon the brownie mixture over the cookie dough layer, dot with the chocolate chunks, and sprinkle with sea salt flakes, if you like. Bake in the centre of the oven for 50 mins-1 hr, or until a skewer inserted into the middle comes out with just a few crumbs clinging to it. Leave to cool completely in the tin before cutting into squares.

Steps:

• Heat oven to 350 degrees. Grease and line a 13-by-9-inch baking pan with parchment paper, leaving a 2-inch overhang on two sides.
• Prepare the brownie layer: In a medium saucepan combine the butter and sugar, and heat over medium until the butter is melted. Remove from the heat and whisk vigorously until well combined. 
• Once the mixture has cooled a bit, whisk in the eggs one at a time. Whisk in the vanilla. 
• Add the flour, cocoa powder, baking powder and salt, and stir to combine. Transfer to a medium bowl. 
• Prepare the cookie batter: Wash and dry the saucepan. Combine the butter and sugar, and heat over medium until the butter is melted. Remove from the heat and whisk vigorously until well combined. 
• Once the mixture has cooled a bit, whisk in the eggs one at a time. Whisk in the vanilla. Add the flour, baking powder and salt, and stir. Stir in 3/4 cup of the chocolate.
• Using two cookie scoops, drop each of the batters into the prepared pan. The pattern can be random, and one dough can be on top of the other; just make sure that once all the batter is added to the pan, you have an even thickness spread out across the pan. Sprinkle the remaining 1/2 cup chocolate on top. 
• Bake until the top looks dry and set, and a toothpick inserted into the center comes out with moist crumbs attached, 20 to 22 minutes.
• Transfer to a rack to cool completely, about 45 minutes. Lift the bar out using the paper and transfer to a cutting board. Cut into bars to serve.
