Description

Sweet cinnamon apples, a hidden custard core, and a golden oat crumble—perfect warm or chilled, and completely portable! Ready in about 35 minutes.


Ingredients

Scale

Apple Layer:

  • 2 large apples, peeled & diced (~2 cups)

  • 1 tbsp maple syrup or light brown sugar

  • ½ tsp ground cinnamon

  • 1 tsp fresh lemon juice

Custard Core:

  • ½ cup vanilla custard (store-bought or quick 3-ingredient version: egg yolk + sugar + cornstarch + ¾ cup warmed milk + ½ tsp vanilla)

Crumble Topping:

  • ½ cup old-fashioned rolled oats

  • ¼ cup almond flour or all-purpose flour

  • 2 tbsp cold unsalted butter or solid coconut oil

  • 1 tbsp light brown sugar

  • Pinch of cinnamon and salt


Instructions

  1. Cook Apples:

    • In a skillet over medium heat, combine apples, syrup/sugar, cinnamon, and lemon juice. Cook 5-7 min until just tender. Let cool slightly.

  2. Make Crumble:

    • In a bowl, mix oats, flour, sugar, cinnamon, and salt. Rub in cold butter or coconut oil with fingers until coarse crumbs form.

  3. Assemble Jars:

    • Layer 1: Divide apples among jars.

    • Layer 2: Spoon 1.5–2 tbsp custard into the center of each jar.

    • Layer 3: Top with oat crumble, pressing slightly.

  4. Bake:

    • Place jars on a baking sheet. Bake at 350°F (175°C) for 15-20 min until topping is golden and apples are bubbly.

  5. Cool & Serve:

    • Warm: Cool 10-15 min and serve with cream or ice cream.

    • Chilled: Cool completely, cover, refrigerate. Perfect for grab-and-go or picnics.

Notes

  • Berry Bliss: Swap half apples for berries.

  • Pear & Ginger: Use pears + ¼ tsp ground ginger.

  • Vegan/Dairy-Free: Coconut oil in crumble + plant-based custard.

  • Nutty Crunch: Add 2 tbsp chopped pecans or walnuts to topping.

  • Chocolate Caramel: Add caramel under custard + sprinkle chocolate chips on top.

Chef’s Hack: Use cold fat in crumble and preheated oven for max crunch. Pat apple layer dry if too juicy.
