Rolled oats and quick cooking / instant oats both work well in baking. Rolled oats will give your recipe a chewier, heartier texture, while quick cooking oats offer a more delicate, softer texture. Quick cooking oats will also cook faster in baked goods, which is something to keep in mind if you're substituting them for rolled oats in a recipe.u003cbr/u003eI wouldn't recommend using steel cut oats in baked goods because they are much more dense than rolled or quick oats and will affect the recipe's texture.
