Really delicious and so easy to make!
Pre-heat your oven to 400F and grease a 12 hole muffin tin.
Mix all the dry ingredients together and then add the yogurt or buttermilk, melted butter, and the egg.
Mix until all the ingredients are combined - do NOT overmix! Add the jalapeno peppers and mix gently again.
Spoon into pre-greased muffin tin and then bake for 20 to 25 minutes or until well risen and pale golden brown.
