One Year Later, This Apple Crumble Is It!

When I first met my husband, I learned pretty quickly that apple and cherry desserts are his absolute favorite. So naturally, I made it my mission to get really good at all things apple. That’s how my Apple Cheesecake Bars, Apple Turnovers, Apple Pie and this Apple Crumble came about.

This crumble took me over a year to really nail. The biggest game changer was cutting the apples into 1/2-inch cubes instead of slices. I picked up that tip from A Beautiful Plate, and wow, it makes such a difference. The apples cook more evenly, get evenly tender, and every bite has the best ratio of warm apples to crisp topping.

After a few more tweaks this summer, I finally got it exactly how I wanted it.

Dessert ingredients including butter, sugar, oats, and spices.

Apple Crumble Recipe With Oats Ingredients

Ingredient	Tips or Swaps
Granny Smith and Honeycrisp apples	Use half Granny Smith and half Honeycrisp for the best sweet-tart flavor. Pink Lady or another firm baking apple also works.
Old-fashioned oats	Use old-fashioned oats for the best texture. Quick oats will be softer, and steel-cut oats will not cook properly.
Brown sugar	Light or dark brown sugar will work. I typically use light but have tested both.
Cold unsalted butter	Keep the butter cold so the topping forms crisp, buttery clusters.
Cornstarch	Toss it thoroughly with the apples to prevent dry pockets and help the juices thicken evenly.
Lemon juice	Fresh lemon juice works best and helps balance the sweetness.

Apple Crumble Recipe With Oats Tips

Keep butter cold: Cold butter creates buttery, crisp clusters in the topping.
Cube apples: Cut them into even 1/2-inch pieces so they cook evenly and become evenly tender.
Chill: Chilling before baking keeps butter cold and helps the topping bake up crisp and crumbly.
Let it cool: Give crumble 15–20 mins so the filling can thicken before serving.
