# Instructions:

01 - Blend softened butter and both sugars on medium speed for 3 minutes until soft and creamy. Add the egg, yolk, and vanilla. Gently stir in the dry ingredients. Roll dough into balls, refrigerate for an hour.
02 - Simmer apple chunks with lemon, cinnamon, sugar, and flour for about 11 minutes over low heat until softened but still a bit firm.
03 - Melt butter, cream, and brown sugar on low for 5 minutes, whisking, until smooth caramel comes together.

05 - Spoon apple mix into cookie centers and drizzle with warm caramel sauce on top.

# Notes:

01 - Dough needs at least 1 hour in the fridge to chill.
02 - The apple pieces should stay a little crisp after cooking.
