Sweet cinnamon apples and creamy oats layered with a crunchy walnut crumble, chilled overnight for a grab-and-go morning treat.

# 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 tbsp chia seeds
05 - 2 tbsp maple syrup or honey
06 - 1/2 tsp ground cinnamon
07 - 1/2 tsp vanilla extract

→ Apple Layer

08 - 1 medium apple, diced
09 - 1 tbsp fresh lemon juice
10 - 1/2 tsp ground cinnamon
11 - 1 tbsp maple syrup or honey

→ Crumble Topping

12 - 1/4 cup rolled oats
13 - 2 tbsp chopped walnuts or pecans
14 - 1 tbsp butter or coconut oil, melted
15 - 1 tbsp brown sugar
16 - 1/4 tsp ground cinnamon

# How To Make It:

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.
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, combine rolled oats, chopped nuts, melted butter, brown sugar, and cinnamon. Mix until the mixture forms coarse, crumbly clusters.
04 - Divide the oat base evenly between two jars or containers. Spoon the apple layer on top of each, then sprinkle generously with the crumble topping.
05 - Seal the jars or containers tightly and refrigerate for at least 6 to 8 hours to allow the oats to absorb the liquid and soften.
06 - Enjoy cold straight from the fridge or let sit briefly at room temperature. For a warmer option, microwave for 30 to 60 seconds.

  • certified gluten free oats are essential if you are cooking for someone with celiac sensitivity.
03 -

  • Layer the crumble on top rather than mixing it in so it stays crunchy until morning.
