Apple Crumble Overnight Oats (Printer-friendly)
Cinnamon-spiced apples layered with creamy overnight oats and a crunchy walnut crumble topping for a cozy morning meal.
# What You 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 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
# How to Make It:
01 - In a medium bowl, combine rolled oats, milk, Greek yogurt, chia seeds, maple syrup, cinnamon, and vanilla extract. Stir thoroughly until evenly blended.
02 - In a small bowl, toss the diced apple with lemon juice, cinnamon, and maple syrup until the apple pieces are well coated.
03 - In a separate bowl, combine rolled oats, chopped nuts, melted butter, brown sugar, and cinnamon. Mix until the mixture forms coarse, crumbly clusters.
04 - Divide half of the oat base mixture between two jars or containers. Layer the seasoned apple evenly over the oats, then sprinkle the crumble topping over each.
05 - Seal the jars or containers with lids and refrigerate for at least 6 to 8 hours, allowing the oats to soften and the flavors to meld.
06 - Enjoy cold straight from the refrigerator, or let sit at room temperature for a few minutes. For a warm option, heat briefly in the microwave.
# Expert Tips:
01 -
- It tastes like apple pie for breakfast but it is genuinely good for you, and that trick never gets old.
- The crumble topping stays surprisingly crunchy overnight, which felt like a small miracle the first time I tried it.
02 -
- Do not skip the lemon juice on the apples or you will open the jar to brown, tired looking pieces that taste fine but look deeply unappealing.
- The crumble topping softens more than you expect, so if crunch is critical to your happiness, consider storing it separately and adding it right before eating.
03 -
- Salt is not in the ingredient list but a tiny pinch in the oat base and another in the crumble makes every flavor sharper and more defined, the same way it does in cookies.
- Flip the jars upside down halfway through chilling if you want the flavors to mingle more evenly, since gravity does most of the flavor distribution work overnight.
