Step 1Preheat grill to medium. Grill bacon on a baking tray until the fat is golden, then lay on kitchen paper to cool and crisp up.
Step 2Preheat oven to 180°C (160°C fan) mark 4 and lightly grease and line a 20.5cm square tin with baking parchment.
Step 3Snip or break the bacon into a small bowl, mix in maple syrup and set aside.
Step 4Melt the butter, sugar and cocoa powder in a large pan – it will look like the mixture won’t come together, but it will with some stirring. Take pan off heat and set aside to cool slightly.
Step 5Beat eggs into butter mixture, one at a time, then stir through the whisky. Sift over the flour and beat until shiny and smooth. Stir in most of the bacon mixture.
Step 6Scrape into prepared tin, level and scatter over the remaining bacon mixture. Bake for 25min or until set. Leave to cool completely in the tin before cutting into squares.
GH TIP For a family friendly alternative, switch the whisky for milk.
