I'm not a baker. In fact, I don't enjoy cooking either. But when I do cook or bake, I'm notorious for trying to substitute all fatty, bad ingredients for healthier options. And 9/10 those cookies that I intended to give to the neighbors, were either thrown in the trash because they were so inedible or my kids ate them with that "what the heck are these?" looks on their faces. So instead of trying to wing it anymore (when I do bake that is), I found this recipe substitution guide helpful;
Or another thing I am notorious for is starting to bake assuming I have all the ingredients. Again 9/10 I don't. So this is another handy list to reference from All Recipes.
