Comment on The Best Paleo Chocolate Sheet Cake (nut-free) by Donna.
This looks phenomenal! Have you ever doubled the recipe to utilize a 13×9 baking dish? And are there any modifications with baking time when using a glass dish vs metal baking pan? One last question, I live at high altitude (~5,600 feet), any modifications I might need to try (more coconut milk, oil or egg)?
