Preheat the oven to 350 degrees. In the mixing bowl of a stand mixer, add the butter, sugar, and brown sugar, and mix until smooth and creamy, and no lumps remain. Add the eggs, and vanilla, and mix well Place baking soda in the hot water, and dissolve. Add to mixing bowl. In a separate bowl, blend the flour, salt, and chocolate chips. Add to mixing bowl, and blend on low until all ingredients are well blended.
Roll cookie dough into large balls, and place each ball in a muffin tin compartment. Place the muffin tin in the oven, and let dough bake for about 15 minutes. Remove the muffin tin, and with a shot glass, press down the center of the cookie dough ball, pressing it up the side of the muffin compartment, and forming a cookie cup. The cookie dough will stick to the shot glass, so just remove the cookie cup, and push it off of the shot glass onto a wire rack to cool. Repeat until all dough has been used.
When cookie cups are cooled, make the Cheesecake filling. In the mixing bowl of a stand mixer, add the softened cream cheese, heavy cream, sugar, vanilla, and Lemon Juice. Mix all together until well blended, smooth, and creamy.
Using a small spoon, fill the centers of the cookie cups with the cheesecake Filling. Melt the milk chocolate chips in the microwave, and swirl a small amount in the center of each cookie cup.
Place the cookie cups in a container, in a single layer, and refrigerate until set, about 4 hours. Serve, and Enjoy!
