Preheat the oven to 350 degrees F (175 degrees C). Line a 12 cup muffin tin with paper liners.
Combine brown sugar, 1/2 cup melted butter, and white sugar in the bowl of a stand mixer fitted with the paddle attachment; beat until thoroughly combined. Add eggs; mix well. Add flour, cinnamon, baking soda, and salt; mix until combined. Add apple cider and 2 teaspoons vanilla extract; beat on high speed for 2 minutes. Evenly divide batter into the prepared muffin cups.
Bake in the preheated oven until tops spring back when lightly pressed, about 20 minutes. Cool in the tin for 5 minutes. Transfer to a wire rack; cool about 20 minutes.
While cupcakes are cooling, combine cream cheese and softened 4 tablespoons butter in the bowl of a stand mixer fitted with the paddle attachment; beat until blended. Add confectioners' sugar and 1 teaspoon vanilla extract; beat until frosting is creamy. Top cooled cupcakes with frosting.
