Step 1

Preheat oven to 325F, with rack on middle or lower middle position. Line baking sheets with parchment paper.

Step 2

In bowl of electric mixer, beat butter and brown sugar until creamy and fluffy, about 1-2 min. Add maple syrup, egg, egg yolk, milk, and vanilla. Beat on low until fully combined.

Step 3

In a separate bowl, whisk together flour, baking soda, salt, cinnamon, and nutmeg. Add rolled oats to flour mixture and whisk together.

Step 4

Using wooden or rubber spatula, fold wet ingredients with dry ingredients. Stir in grated apples until fully incorporated. If dough is sticky, chill 30 min to an hour.

Step 5

Form rounded 1 tablespoons of dough 2 inches apart on parchment lined baking sheets.

Step 6

Bake 11-13 minutes, or just until lightly golden; don't overbake. Cookies will set upon cooling. Transfer warm cookies to wire rack and let cool.

Step 7

Place caramels and water in small heavy saucepan. Stir continuously over low heat until melted and smooth. Let rest a bit until it's no longer too hot to handle. Using fork or Ziploc baggie with tiny hole cut out of the corner, drizzle warm caramel over cooled cookies. Be careful - melted caramel is hot!
