Fire up your pellet smoker (or oven) to 400 degrees. Give that mini muffin a healthy spray of cooking spray.
Bowl 1 (Dry's): Combine your flour, baking powder, baking soda, sugar and salt. Whisk together and set aside.
Bowl 2 (Wet's): Crack the egg and lightly beat. Add the buttermilk and vanilla extract until the egg is smooth.
Combine bowl 2 with bowl 1 and add the melted butter. Stir until well combined. Add in that grated/shredded cheese until that beautiful dough is all together.
Take a spoon and scoop into that greased muffin tin. Put less than you think - these things balloon up pretty healthily. Put in your smoker/oven for about 10 minutes - but keep an eye on them after 5.
Eat while warm! If there's any left to save, definitely pop it in the microwave - they're so good with a little heat.
