So, this recipe out of the Home Cooking vintage recipe book calls for a 9×12 pan. I’ll admit – I just assume that my pans are 9×13. This had me running a quick Google and Amazon search to see how common the 9×12 size is. And, wow, I feel like I should look at the sticker when I purchase a pan. Some of mine may be 9×12 and some may be 9×13. They fit together so nicely – I’ve never thought about a difference in size. But now I will. Every. Time. 😂
All of that to say this – the recipe calls for a 9×12 pan. If you make it in a 9×13, then I assume the bar cookies will be flatter than if you used the smaller pan size. Use what you will – they’ll still be delicious.
Something to keep in mind when you pick up a vintage recipe book that was put together by a community group or church. The recipe may not be *well-written*. Be sure to read it several times to make sure you’re understanding the intent of the person who provided the recipe. I’ve included a picture of this recipe from the book at the bottom of this post as an example of one that wasn’t written in a format that we typically expect in today’s era.
