Agree Dennys are better or can make your own and tastes just as good if not better. Pancakes very cheap to make. Most recipes calling for buttermilk will taste just as good.
If you want to be lazy but still have that same great taste than by a complete mix BUT use milk instead of water, add an extra egg or 2 and add a teaspoon or so of vanilla. Super easy and tastes great. I will buy a box of complete mix(don't even looks at their directions). Dump whole box in bowl, add 4 eggs, add milk to get consistency I want. Than add a splash of vanilla. Keep left over batter in fridge. Lasts a few days no problem. Doggies love pancake days as well.
