Place the Oreo and coconut flakes in a food processor with fillings intact. Pulse for a few seconds until crumbly, add the melted butter, and combine.
Place the crust in a tart pan and press firmly on the bottom and sides of the pan using your fingertips.
Place in the oven for 7 minutes and allow to cool completely.
Pour the cream in a heavy bottom saucepan on medium-low heat and bring to a gentle boil
add the cubed butter, stir and remove from heat.
Pour the cream into a bowl with the chopped chocolate. Let stand for about 2 minutes. Stir gently until you get a silky smooth mixture. Add the raspberry extract and Irish cream, stir once more.
Pour the ganache into the cooled Oreo crust. Layer the raspberries on top, place in the refrigerator overnight or up to 2 hours plus until set.
Garnish to your satisfaction and enjoy !
PS: I used 70% dark Lindt chocolate. You can use both milk and dark chocolate if you wish.
