S'mores Cheesecake Cupcakes

Step 1
Stuff 1 chocolate chip inside each marshmallow, using a hot metal spoon to make the marshmallow stick to the chocolate and form a very small ball. Place on a plate lined with waxed paper. Transfer to the freezer.

Step 2
Preheat oven to 350 degrees F (175 degrees C). Grease 2 muffin tins.

Step 3
Mix graham cracker crumbs with melted butter in a bowl.

Step 4
Pack graham cracker mixture into the muffin tins with the back of a spoon, creating a crust on the bottom of each cup.

Step 5
Beat cream cheese and sugar in a bowl with an electric mixer until smooth. Blend in milk. Beat in eggs one at a time, mixing just enough to incorporate. Beat in sour cream, flour, and vanilla extract until batter is smooth.

Step 6
Fill muffin cups halfway with batter. Place a frozen marshmallow ball in the center of each. Cover with remaining batter.

Step 7
Bake in the preheated oven until set, 15 to 20 minutes. Let cool completely, about 30 minutes.

Step 8
Spoon marshmallow cream into a small pot. Heat over low heat until soft, about 5 minutes. Mix in cinnamon and cocoa powder. Pipe frosting over cooled cupcakes.
