Step‑by‑Step Instructions
- Preheat your oven to 350°F (175°C) and prepare a 9x9 baking pan by lightly greasing it with nonstick spray.
- Combine all-purpose flour, light brown sugar, salt, and ground cinnamon. Cut in cold unsalted butter until mixture resembles coarse crumbs.
- Sift together all-purpose flour, baking soda, cinnamon, nutmeg, and salt. In another bowl, whisk vegetable oil, granulated sugar, egg, egg white, and vanilla until smooth.
- Gently fold the wet mixture into the dry ingredients until just combined. Fold in diced apples and chopped walnuts.
- Pour the batter into the greased baking pan and sprinkle the crumb topping over it, pressing lightly.
- Bake for 30 to 35 minutes until edges are golden and firm. A toothpick should come out with a few moist crumbs.
- Prepare the warm vanilla glaze by whisking melted butter, powdered sugar, milk, vanilla, and a pinch of salt until smooth.
- Drizzle the warm glaze over the cake after it cools for 10-15 minutes, allowing it to set briefly before slicing.
- Slice the cake into squares and serve warm, optionally with whipped cream or vanilla ice cream.

Notes
Ensure butter is cold for the crumb topping and avoid overmixing for a lighter cake.
