Preheat your oven to 400 degrees F and line two muffin tins with cupcake liners or use silicone cupcake/muffin pans.
Pour the shredded coconut onto a baking sheet. Bake for 8-10 minutes, tossing halfway through, or until the coconut is lightly golden brown.
Place an Oreo cookie in the bottom of each muffin cup, then set aside.
In a medium saucepan, combine the butter and brown sugar. Bring the mixture to a rolling boil, then continue to stir for 3 minutes so that the mixture doesn’t burn.
Remove the butter toffee from the heat and quickly drop a tablespoon on top of each Oreo. A cookie scoop is a helpful way to evenly fill each cup.
Place the tins in the oven and bake for 4 minutes.
Remove from the oven and immediately pour 1 tablespoon of white chocolate chips onto each cup.
Allow the chocolate to melt a bit and then spread the chocolate with the back of a spoon. NOTE: If using standard sized chips, you may have to pop them back in the oven for a minute or two to help melt them.
Sprinkle with the toasted coconut. You can also use festive springtime sprinkles, if you like.
Place the assembled crack cookies in the fridge to cool and set for 2-3 hours. This tip is important. Always make sure the toffee layer is fully set and cooled before peeling the paper liners off!
