Introduction
and filled with sweet-tart apple pieces that keep every slice moist for days. The cinnamon swirl does more than look pretty:
it melts into the batter as it bakes, creating pockets of caramel-like flavor and a gentle ribbon of spice that perfumes the whole cake.
This version is designed for consistency: the apples are lightly coated with flour so they don’t sink, the batter mixes quickly
without fuss, and the bake time works whether you prefer a classic round cake or an easy 9×13 pan for casual slicing.
Add the optional vanilla glaze for a bakery finish, or serve it plain with coffee for a simple, cozy treat.
Best apples to use: Choose firm apples that hold shape (Granny Smith, Honeycrisp, Pink Lady, Braeburn).
Softer apples can turn mushy and make the cake wet.

For easy serving at gatherings, a 9×13 pan bakes a little faster and slices neatly into squares.
