Seeds - You can use chia seeds, basil seeds, flaxseeds, hemp seeds, or any other seeds you like. Sweetener - we use maple syrup, but you could use another sweetener such as honey, brown sugar, golden syrup, condensed milk, or your favorite sweetener. If you are using sweet-flavored yogurt, you might want to leave out the sweetener to avoid an overly sweet breakfast. Yogurt - you can use thick store-bought Greek yogurt or homemade yogurt. If you wanted to use steel-cut oats, you could, but they remain grainy and become chewy and gummy in texture rather than thick and creamy. Oats - Use either old-fashioned rolled oats or quick oats - these types of oats are great for making thick and creamy overnight oats. Milk - We use whole milk or homemade soy milk, but any milk will work for these recipes. To make these overnight oats, you will need yogurt, milk, oats, maple syrup (or a sweetener of your choice), vanilla, plus additional ingredients as stated in the recipe you choose.
