I recently purchased a bag of First Street Cake Mix at Smart &Final. I'm a frequent shopper of this store for most of my baking needs. However, I had not tried this particular product. I didn't think it would be too different from popular brands. I was disappointed. I followed the directions on the package and the batter came out very runny. Because the batter was runny, it took longer to bake and had many sunken areas. Has anyone tried this product?
