  • 1.75 cup milk dairy or unsweetened almond milk
  • 0.5 cup unsweetened applesauce
  • 0.25 cup pure maple syrup
  • 2 tsp vanilla extract
  • 2 tbsp unsalted butter, melted
  • 1.25 tsp baking powder
  • 1.5 tsp ground cinnamon
  • 0.25 tsp ground nutmeg
  • 0.5 tsp fine sea salt
  • 1.5 cup chopped apples peeled or unpeeled
  • 0.5 cup chopped walnuts optional
  • 0.75 cup rolled oats for crumble topping
  • 0.33 cup all-purpose flour for crumble topping
  • 0.25 cup brown sugar for crumble topping
  • 0.5 tsp ground cinnamon for crumble topping

Instructions

Preparation Steps

  • Heat oven to 350°F. Grease an 8- or 9-inch square baking dish.
  • Whisk milk, applesauce, maple syrup, vanilla, and 2 tbsp melted butter in a large bowl.
  • Stir in 2 1/4 cups oats, baking powder, 1 1/2 tsp cinnamon, nutmeg, and salt until combined.
  • Fold in chopped apples and walnuts. Spread the mixture evenly in the prepared dish.
  • Combine 3/4 cup oats, flour, brown sugar, and 1/2 tsp cinnamon in a bowl. Drizzle in 3 tbsp melted butter and toss to form crumbles.
  • Scatter crumble evenly over the oatmeal base. Bake until set and golden, 35–40 minutes.
  • Let rest 10 minutes. Serve warm, plain or with yogurt or a drizzle of maple syrup.

Notes

Variation: Swap walnuts for pecans, or add 1/2 cup raisins to the batter. For dairy-free, use almond milk and coconut oil in place of butter. Storage: Refrigerate leftovers up to 4 days or freeze portions for 2 months; reheat with a splash of milk.
