Start by taking a large bowl. Add the steel cut oats, milk, and sea salt to the bowl. Stir the mixture well until everything is evenly combined. Make sure all the oats are submerged.

Now, it’s time to incorporate the nut butter. I usually choose peanut butter, but feel free to go with almond or cashew butter if that’s your style. Stir in the nut butter and sweetener until fully blended. You want a smooth texture here, not chunky.

Here comes the fun part! Add any optional enhancements at this stage. Toss in chia seeds for texture, ground cinnamon for warmth, or even a scoop of protein powder if you're looking for an extra boost. If you have any citrus zest or vanilla extract, sprinkle those in as well.

Cover your bowl with a lid or plastic wrap to seal it. Pop it in the refrigerator and let it work its magic overnight. The oats will absorb the liquid and soften beautifully by morning.

When you wake up, grab your oats from the fridge. Give them a good stir. At this point, feel free to adjust the texture with additional milk if it feels too thick. Now is also the chance to add any last-minute toppings like fresh fruits, nuts, or a sprinkle of coconut before enjoying.
