Lucky's Golden Ticket Cupcakes

1. Preheat oven to 350° F. Line 24 cupcake molds with paper liners.
2. In a large mixing bowl, beat together the butter, sugar, flour, baking powder, baking soda, and salt until mixed into small dry crumbs. 
3. Combine the milk and vanilla, then pour in the flour, beating until smooth. Beat in the eggs, one at a time, until combined. Add the yogurt, beating until just combined.
4. Divide the batter evenly among the prepared pans. Transfer to the oven and bake 22-25 minutes, until the tops are just set, and no longer wiggly in the center. Remove and let cool.
5. To make the frosting. Melt together 1 stick butter, brown sugar, and cream in a medium saucepan. Bring to a boil and cook 2 minutes, or until the sugar has dissolved. Add a pinch of salt. Remove from the heat and add to the bowl of a stand mixer. Place the bowl in the freezer (or fridge for longer) for 15 minutes or until cool to touch.
6. Grab the cooled butter mixture from the freezer and add the remaining 1 stick butter, vanilla, and powdered sugar to the bowl. Beat together until well combined, adding more sugar as needed.
7. Frost each cupcake. Decorate as desired with Lucky Charms. I lightly crush the marshmallows with my fingers, then sprinkle over each cupcake. You could use St.Patrick's Day sprinkles as well. Or do them up for Easter!
