Turns out, this version is really close to the original. I couldn't really tell any difference, so I will be making this from now on....much cheaper than actually buying the TS kit too!!
3 C. self rising flour
1/2 C. sugar
12 oz. beer (seasonal or flavored beers are great, but any beer will do! You can also use another carbonated drink if you don't have any beer on hand)
3 Tbs. butter, melted
Preheat oven to 350 degrees. Combine the flour, sugar, and beer. Mix just until combined. Spoon into a greased loaf pan. Pour melted butter over the batter and bake for 55-60 minutes.
