Divide the oats into two airtight containers and top them with crumbled Biscoff cookies.
Pour almond milk over the oats, cover, and refrigerate overnight. When you're ready to eat, warm the Biscoff cookie butter spread in a microwave-safe bowl and drizzle it over the top. Alternatively, you can top them with the melted cookie butter to create a topping as the oats set overnight.
Notes
Expert Tips:
For the best results, store the overnight oats in a jar with room to spare since the oatmeal expands as it rehydrates, and so will any mix-ins you add.
I find a 1:1 ratio of one part old-fashioned oats and one part almond milk the best. Use less liquid if you want thicker oatmeal and more if you like it runny.
Despite the name overnight oats, they only need to soak for 2-3 hours before you can enjoy them. However, the longer you soak the oats, the softer they will become.
Give the mixture a good stir before adding toppings and digging in. If the oats seem dry after sitting in the fridge, add another splash of almond milk.
