Apple Crumble Overnight Oats (Printable)
Cinnamon-spiced apples and creamy oats layered with a crunchy brown sugar-walnut crumble, prepped the night before.
# What You'll Need:
→ Oat Base
01 - 1 cup rolled oats
02 - 1 cup milk (dairy or plant-based)
03 - 1/2 cup plain Greek yogurt
04 - 2 tablespoons chia seeds
05 - 2 tablespoons maple syrup or honey
06 - 1/2 teaspoon ground cinnamon
07 - 1/2 teaspoon vanilla extract
→ Apple Layer
08 - 1 medium apple, diced
09 - 1 tablespoon fresh lemon juice
10 - 1/2 teaspoon ground cinnamon
11 - 1 tablespoon maple syrup or honey
→ Crumble Topping
12 - 1/4 cup rolled oats
13 - 2 tablespoons chopped walnuts or pecans
14 - 1 tablespoon butter or coconut oil, melted
15 - 1 tablespoon brown sugar
16 - 1/4 teaspoon ground cinnamon
# Steps:
01 - In a medium bowl, combine rolled oats, milk, Greek yogurt, chia seeds, maple syrup, ground cinnamon, and vanilla extract. Stir thoroughly until evenly blended and no dry pockets remain.
02 - In a small bowl, toss the diced apple with fresh lemon juice, ground cinnamon, and maple syrup until the apple pieces are well coated.
03 - In a separate bowl, mix rolled oats, chopped nuts, melted butter, brown sugar, and ground cinnamon. Work the mixture with your fingers or a fork until it forms coarse, crumbly clusters.
04 - Divide the oat base evenly between two jars or airtight containers. Layer the seasoned apple pieces on top of the oats in each jar, then sprinkle the crumble topping generously over the apple layer.
05 - Seal the jars or containers tightly with lids and refrigerate for at least 6 to 8 hours, allowing the oats to absorb the liquid and soften.
06 - Enjoy straight from the refrigerator cold or let sit briefly at room temperature. For a warmer option, microwave for 30 to 60 seconds before serving.
# Expert Tips:
01 -
- It captures every warm, comforting flavor of apple crumble without heating up your kitchen.
- The layers stay distinct overnight, so every spoonful gives you creamy, fruity, and crunchy all at once.
02 -
- The crumble topping softens the longer it sits, so if you want maximum crunch, store it separately in a small bag and add it right before eating.
- Do not skip the lemon juice on the apples or you will open the jar to brown, tired looking pieces that have lost their brightness.
03 -
- Toast the nuts for the crumble topping in a dry pan for two minutes before adding them, and you will unlock a depth of flavor that makes people ask what your secret is.
- Let the oat base sit for ten minutes before layering so the chia seeds begin to gel and the mixture thickens enough to create clean, distinct layers.
