To make a 9X13 can I double this recipe?
I want to make the following recipe but in an 9x13in pan. The recipe is for an 8in. pan. Can I just double the ingredients?
Doubling this recipe and using a 9x13 pan should give you a slightly higher (by about 1/8 inch) finished product. But I don't see why that would be a major issue, as long as the 8x8 baking dish version came right up over the edges of the dish. If it were my decision, I'd give it a go ...
Yeah, just to do the math: an eight inch pan is 64 square inches (8x8=64), so double would be 128 square inches. 9x13 = 117 square inches. So the difference between doubled 8x8 and 9x13 is 11 square inches out of roughly 120, or less than ten percent difference. Pretty negligible in my book. Just for reference, to convert a recipe for a 9x9 pan to 9x13 you multiply by 1.5 (9x9=81, times 1.5 is 121.5).
Oh, and the 9x13 should take slightly longer to bake, since the center is slightly farther from the edges and it's slightly thicker.
