Preheat the oven to 350 degrees F and line cupcake pans with papers.
Place the cake flour, graham flour, brown sugar, baking powder, baking soda, salt, and cinnamon in the bowl of an electric mixer and stir together to combine.
Add the butter, and mix on medium-low speed until the mixture resembles damp sand (about 1 minute).
Mix in the eggs on medium-low speed, until smooth (about 1 minute).
Add the sour cream, milk, honey, and vanilla, and mix on medium-high speed for about 2 to 3 minutes, to aerate the batter and build the cake's structure.
Transfer the batter to the prepared pans and bake for 16 to 20 minutes, or until a toothpick inserted in the thickest part of a cupcake comes out clean or with a few moist crumbs.
Cool completely, then fill with marshmallow and top with chocolate frosting.
Garnish with micro-marshmallows.
