Preheat the oven to 350 degrees and line a cupcake pan with liners.
In a medium bowl, whisk together the flour, baking powder, Old Bay seasoning and salt. Set aside.
1 ¼ cup all purpose flour, 1 ½ teaspoon baking powder, ½ teaspoon Old Bay seasoning, ⅛ teaspoon salt
In the bowl of a stand mixer, beat butter until smooth, about 2 minutes. Then add in sugar and beat for another 2 minutes.
8 tablespoon unsalted butter, ¾ cup granulated sugar
Add in the eggs, one at a time, followed by the vanilla.
2 large eggs, 1 ½ teaspoon vanilla extract
Add half of the flour mixture and half of the buttermilk and mix for a minute or two, until combined. Then add in the remaining flour mixture and buttermilk and mix for 2 more minutes.
Divide the batter into the prepared cupcake pan filling each liner ¾ of the way full.
Bake for 20-22 minutes or until a toothpick inserted in the center comes out clean. Remove cupcakes from the oven and allow to cool in the pan for 5 minutes, then remove from the pan and let cool completely on a wire rack.
