Apple Crumble Overnight Oats (Printable)

Cinnamon apples and creamy oats layered with a crunchy topping, chilled overnight for a ready-to-enjoy breakfast.

# 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

# Directions:

01 - In a medium bowl, combine the rolled oats, milk, Greek yogurt, chia seeds, maple syrup, ground cinnamon, and vanilla extract. Stir thoroughly until evenly blended and the oats are fully coated.
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 and slightly softened.
03 - In a separate bowl, combine the rolled oats, chopped nuts, melted butter, brown sugar, and ground cinnamon. Mix with a fork until the mixture resembles coarse, crumbly streusel.
04 - Divide the oat base evenly between two jars or airtight containers. Spoon the seasoned apple mixture over the oat layer in each jar, then sprinkle the crumble topping generously over the apples.
05 - Secure the lids on the jars and refrigerate for at least 6 to 8 hours, allowing the oats to absorb the liquid and the flavors to meld together.
06 - Enjoy cold straight from the fridge, or let sit at room temperature for a few minutes. For a warmer option, microwave briefly for 30 to 45 seconds before serving.

# Expert Suggestions:

01 -
  • It tastes like dessert for breakfast but quietly packs protein, fiber, and real fruit into every spoonful.
  • You do all the work the night before, so your morning self gets to open the fridge and feel brilliantly taken care of.
  • The crumble topping stays surprisingly crunchy overnight, giving you that satisfying contrast of creamy and crisp.
02 -
  • Do not skip the chia seeds because they are the quiet heroes that transform runny milk and oats into a thick, creamy pudding overnight.
  • Dice the apple fairly small, about the size of a pea, so every bite gets fruit without fighting through large chunks.
03 -
  • Toast the nuts in a dry skillet for three minutes before adding them to the crumble and you will unlock a warmth and depth that raw nuts simply cannot match.
  • Add a tiny pinch of salt to the crumble topping because salt makes every sweet thing taste more like itself.
