1/2 butter (1 stick-I like using unsalted butter)
1/2 cup of brown sugar packed
1/2 cup of granulated sugar
1 large egg
1/2 tablespoon vanilla extract
1 3/4 cups of all-purpose flour
1/2 tsp salt
1/2 tsp baking soda
1 bag of milk chocolate chips
1. Preheat oven to 350 degrees F. Spray a standard-size muffin tin with cooking spray. Place 1/2 cup chocolate chips in a Ziploc bag, and seal shut. Lay the Ziploc bag flat in the microwave, spreading out the chocolate chips in a single layer. Microwave for 30 seconds. Remove bag and flip, microwaving for an additional 10-15 seconds until all the chips are softened. Set aside to cool.
2. With an electric mixer, cream the butter and sugars until light and fluffy, about 3-5 minutes. Add egg and vanilla and beat until well combined. Meanwhile, in a separate bowl, whisk together the flour, salt, and baking soda. Add to the wet ingredients and beat on low speed until just combined. Add the remaining chocolate chips (1 cup) and stir to combine.
3. Using half the cookie dough, scoop 1.5-2 tbsp of dough, flatten it out a bit and place in the bottom of the muffin tin. Repeat for a total of 10 cookies. Cut a small tip in the corner of the Ziploc bag, and gently squeeze a layer of chocolate over the cookie. Scoop and flatten the remaining dough and place it on top of the chocolate layer. Bake at 350 for 15-20 minutes, until the edges are just browned. As soon as they come out of the oven, run a knife around the edges to make for easy removing later. Cool completely before removing from the muffin tin, running a knife around the edge to help loosen.
These are good as mini muffins, too! Try baking at 350 for 9 mins. Enjoy!
