Snickerdoodle overnight oats are a no-cook breakfast that tastes like a cinnamon-sugar cookie in a jar. Rolled oats soften overnight in milk, yogurt, and a touch of maple syrup, while cinnamon and vanilla bring the classic snickerdoodle flavor. It’s a make-ahead meal that’s creamy, lightly sweet, and perfect for busy mornings.
Ingredients
- 1 cup (90 g) old-fashioned rolled oats (not instant or steel-cut)
- 1 cup (240 ml) milk of choice (dairy, almond, or oat milk)
- 1/2 cup (120 g) plain Greek yogurt or dairy-free yogurt
- 2 tbsp (30 ml) maple syrup or honey
- 1 tbsp (15 g) chia seeds (optional, for thicker texture)
- 1 tsp ground cinnamon
- 1/2 tsp vanilla extract
- 1/8 tsp cream of tartar (optional, for tangy cookie flavor)
- Pinch of salt
- For the topping: 1 tbsp (13 g) sugar mixed with 1/2 tsp ground cinnamon
Instructions
- In a medium bowl or a 1-quart jar, combine the oats, milk, yogurt, maple syrup, chia seeds (if using), cinnamon, vanilla, cream of tartar (if using), and salt.
- Stir well until everything is fully incorporated and no dry oats remain. The mixture will look thin; that’s normal.
- Divide the mixture between two jars or airtight containers (about 1 cup/240 ml each).
- In a small bowl, mix the topping sugar and cinnamon. Sprinkle half over each jar.
- Seal the jars and refrigerate for at least 8 hours, or overnight (up to 4 days).
- In the morning, stir the oats. If they’re too thick, add a splash of milk to loosen. Enjoy cold, or warm gently in the microwave for 30–45 seconds if you prefer.
Tips
- Use old-fashioned oats, not instant or steel-cut. Instant oats turn mushy; steel-cut oats stay hard and crunchy even after soaking. Rolled oats give the perfect chewy-tender texture.
- Don’t skip the yogurt. It adds creaminess and a slight tang that mimics the buttermilk in a real snickerdoodle cookie. For a dairy-free version, use a thick coconut or soy yogurt.
- Adjust sweetness to taste. Maple syrup is less sweet than sugar, so if you like a sweeter breakfast, add an extra teaspoon or two. You can also use brown sugar for a deeper molasses note.
- Stir before eating. The cinnamon-sugar topping will settle on top; stirring distributes it evenly. If you prefer a crunchy topping, add it fresh just before serving instead of overnight.
Serving Suggestions
Serve these oats cold straight from the fridge, or warm them up for a cozy fall-style breakfast. Top with a few toasted pecans or walnuts, a drizzle of extra maple syrup, or a spoonful of apple butter. They pair well with a side of fresh fruit like sliced bananas or berries. For a more filling meal, add a spoonful of nut butter on top.
Variations
- Apple snickerdoodle: Stir in 1/2 cup (75 g) finely diced apple along with the oats. The apple softens overnight and adds natural sweetness.
- Chai-spiced: Replace the cinnamon with 1 tsp chai spice blend, or add a pinch of cardamom and nutmeg along with the cinnamon.
- Protein-packed: Add 1 scoop (about 30 g) vanilla or cinnamon protein powder. You may need to increase the milk by 2–3 tbsp (30–45 ml) to keep the oats creamy.
- Vegan: Use plant-based milk and yogurt, and swap honey for maple syrup. The oats still turn out creamy and delicious.
Storage and Reheating
Store the oats in airtight jars in the refrigerator for up to 4 days. The chia seeds (if used) will absorb liquid over time, so the oats will thicken; add a splash of milk before serving if needed. You can also freeze them in individual jars for up to 3 months—thaw overnight in the fridge before eating. To reheat, microwave in a microwave-safe container for 30–60 seconds, stirring halfway. Do not leave the oats at room temperature for more than 2 hours.
Frequently Asked Questions
Can I use quick oats instead of rolled oats? Yes, but the texture will be much softer and more porridge-like. Quick oats absorb liquid faster, so they may be ready in as little as 4 hours. If you prefer a chewier bite, stick with rolled oats.
Can I make this without yogurt? Absolutely. Replace the yogurt with an equal amount of milk or a dairy-free milk alternative. The oats will be slightly less creamy and a bit thinner, but still delicious. You can also use a spoonful of mashed banana or applesauce to add body.
How long do overnight oats last in the fridge? Properly stored in an airtight container, they stay good for up to 4 days. After that, the oats can become mushy and the flavor may dull. Always check for any off smell or mold before eating.
Can I eat these warm? Yes. Microwave the oats for 45–60 seconds, stirring halfway, until heated through. Warm oats are especially comforting in winter. Just note that the yogurt may curdle slightly if overheated, so heat gently.
Why are my oats too thick? This usually happens if you used extra chia seeds or let them sit for more than 2 days. Simply stir in 1–2 tablespoons (15–30 ml) of milk until you reach your desired consistency. You can also add a little water, but milk keeps it creamier.
Can I use steel-cut oats? Not without a long soak. Steel-cut oats need at least 12 hours and even then they remain quite chewy. For a better result, use rolled oats. If you only have steel-cut, blend them briefly in a food processor to break them down, then soak for at least 12 hours.
