1¼cupLotus Biscoff cookie crumbsor graham cracker crumbs
6ozchocolate chipssemi-sweet
For the Blondie
⅔cupunsalted buttermelted
1cuplight brown sugaralso called muscovado, firmly packed
⅓cupsuperfine sugaror caster sugar
1whole egg
1egg yolk
2teaspoonvanilla extract
1½cupall-purpose flouror plain flour
½tablespooncornstarch
¼teaspoonbaking powder
¾teaspoonsalt
4ozchopped walnuts
2ozsweetened flaked coconut or dessicated coconut
caramel or toffee sauce
Instructions
Preheat oven to 350°F (175C or 160C Fan) and line your baking tin with parchment paper.
Mix together the cookie crumbs and ¼ cup melted butter. Press this into the base of the lined pan and top with chocolate chips. Place in heating oven for 10 minutes to soften the chocolate chips. Remove and carefully spread the chips across the base with a spatula to smooth the melted chocolate.
In a large bowl, beat together the ⅔ cup melted butter and sugars until fully combined. Add the egg, yolk and vanilla, beating to incorporate.
In a separate bowl, mix together the flour, cornstarch, baking powder and salt. Add this to the sugar mixture, beating to combine.
Reserve a small handful of chopped nuts and coconut for decoration later. Fold the rest into the batter until evenly incorporated. Try not to over mix.
Spoon the batter into the pan, over top the chocolate covered base and spread evenly. Place in the oven and bake for about 45 minutes, until a toothpick inserted about an inch from the edge comes out mostly clean.
Remove from the oven and cool in the pan for about 2 hours (see note). While cooling, top with drizzle of caramel or toffee sauce and the reserved walnuts and coconut.
Remove from the pan by lifting out the parchment paper lining. Transfer to a plate to slice and serve.
Notes
You can remove these from the pan more quickly, before they are cooled, but these will be messy to slice. This recipe is intended for a gooey finish to the blondie, which is best achieved by letting them cool and firm up a bit after baking.
