2In a large mixing bowl, cream together butter and sugar.
3Mix in flour, baking powder and salt at a low speed, followed by the vanilla and milk, adding in the milk as needed to make the dough come together without being sticky (it’s possible you might not need to add milk at all).
The dough should come together into a soft, not-too-sticky ball. Add in a bit of extra flour if your dough is very sticky.
4Roll the dough (working in two or three batches) out between pieces of wax paper to about 1/4-inch thickness (or slightly less) and use a 1 1/2-inch cookie cutter to make rounds.
Place on a parchment lined baking sheet and use a knife, or the end of a wide straw, to cut a smaller center hole. Repeat with remaining dough.
5Alternatively, use scant tablespoons of dough and press into an even layer in a mini donut pan to form the rounds.
Bake cookies for 10-12 minutes, until bottoms are lightly browned and cookies are set. If using a mini donut pan, bake for only about 10 minutes, until edges are light gold.
6Cool for a few minutes on the baking sheet then transfer to a wire rack to cool completely.
7DIRECTIONS FOR TOPPING
8Preheat oven to 300. Spread coconut evenly on a parchment-lined baking sheet (preferably one with sides) and toast 20 minutes, stirring every 5 minutes, until coconut is golden. Cool on baking sheet, stirring occasionally. Set aside.
9Unwrap the caramels and place in a large microwave-safe bowl with milk and salt. Cook on high for 3-4 minutes, stopping to stir a few times to help the caramel melt. When smooth, fold in toasted coconut with a spatula.
Using the spatula or a small offset spatula, spread topping on cooled cookies, using about 2-3 tsp per cookie. Reheat caramel for a few seconds in the microwave if it gets too firm to work with.
10While topping sets up, melt chocolate in a small bowl. Heat on high in the microwave in 45 second intervals, stirring thoroughly to prevent scorching. Dip the base of each cookie into the chocolate and place on a clean piece of parchment paper. Transfer all remaining chocolate (or melt a bit of additional chocolate, if necessary) into a piping bag or a ziplock bag with the corner snipped off and drizzle finished cookies with chocolate.
Let chocolate set completely before storing in an airtight container.
