Brown the butter: For a detailed tutorial, see this post on how to brown butter. Once browned, stir in one ice cube to cool down a little more quickly. Then place in fridge to solidify. This will take ~1-2 hours. I know, ugh. But, trust me on this one! The liquid brown butter for these cookies makes the cookies too thin and flat, lacking the yummy chew. So the solidified brown butter is key. 1 cup unsalted butter
Preheat the oven to 350°F. Line 2 baking sheets with parchment paper or silicone baking mats. Set aside.
Add the solidified brown butter and both sugars to a stand mixer fitted with the paddle attachment and beat for 3-4 minutes until creamy.
1 1/4 cup dark brown sugar, packed, 1/4 cup granulated sugar
Meanwhile, whisk together the dry ingredients. Set aside.
2 2/3 cups all purpose flour, spooned and leveled, 1 1/2 tsp. cream of tartar, 1 tsp. kosher salt, 1 tsp. baking soda, 1/2 tsp. baking powder
Add in the egg, egg yolk, milk, and vanilla extract. Beat again until combined.
1 large egg, room temperature, 1 large egg yolk, room temperature, 1 Tbsp. whole milk, room temperature, 1 Tbsp. vanilla extract (yes, a whole tablespoon!)
Gradually add in the dry ingredients on a medium-low speed. Mix just until combined.
Unwrap the caramels and slice them in half. You won't need to use the whole bag of caramels.
Werther's Soft Caramels or Kraft Caramels
Scoop the cookies using a 2 Tbsp. scoop, or you can make a little smaller if preferred.
Flatten the cookie dough, place a piece of the caramel in the center, and wrap the cookie dough around the caramel. Ensure the cookie dough wraps around it completely and is sealed so the caramel doesn't ooze out.
Mix the granulated sugar and cinnamon together in a small dish and roll each cookie dough ball in the cinnamon and sugar. Repeat this with remaining cookie dough.
3 Tbsp. granulated sugar, 1 1/2 tsp. ground cinnamon
Place cookies on the prepared baking sheets, I like to bake 6 cookies at a time. Bake for 7-9 minutes, being careful not to overbake. Allow to cool on the baking sheet for a few minutes, then transfer to a cooling rack. Sprinkle any leftover cinnamon/sugar on top, and flaky sea salt.
