Simple & Nourishing Ingredients

Each ingredient in this recipe contributes to flavor, texture, and nutritional value. Here’s what you’ll need to build your best Classic Overnight Oats:

Gluten-Free Rolled Oats: The base of the recipe. They absorb the liquid overnight to create a soft, spoonable texture.
Non-Dairy Milk: Adds creaminess. Almond, oat, or coconut milk all work beautifully.
Chia Seeds: These tiny seeds soak up liquid and help thicken the oats while adding omega-3s and fiber.
Nut Butter (like almond or peanut): Enhances creaminess and offers healthy fats and protein.
Maple Syrup: A natural sweetener that adds a gentle touch of sweetness.
Vanilla Extract: Rounds out the flavor with warm, aromatic notes.
Cinnamon: Adds a subtle spice that pairs perfectly with oats.
Pinch of Sea Salt: Balances sweetness and enhances the overall flavor.

Ingredient Swaps & Substitutions

If you’re short on ingredients or want to tailor the recipe to dietary needs, here are some great alternatives:

Oats: Use quick oats for a softer texture or steel-cut oats (par-cooked) for chewiness.
Chia Seeds: Swap with ground flaxseed for similar texture and nutrition.
Maple Syrup: Replace with honey, agave, or date syrup.
Nut Butter: Sunflower seed butter works for nut-free options.
Dairy-Free Milk: Try soy milk for extra protein or rice milk for a lighter option.

These adjustments still result in delicious and creamy Classic Overnight Oats with no compromise on flavor.
