Preheat the oven to 177°C and thoroughly grease a 9×13-inch baking pan.

In a large bowl, whisk together flour, baking powder, baking soda, salt, cinnamon, nutmeg, ginger, and allspice until well combined. Set aside.

In a medium bowl, whisk oil, granulated sugar, brown sugar, applesauce, eggs, vanilla extract, and orange juice until smooth and fully incorporated.
04 -
Pour the wet ingredients into the dry ingredients and whisk until combined. Fold in the chopped apples until evenly distributed throughout the batter.
05 -
Pour and spread batter evenly into the prepared pan. Bake for 45–50 minutes. Around the 30-minute mark, loosely tent with aluminum foil to prevent over-browning. The cake is done when a toothpick inserted in the center comes out clean.

Remove the cake from the oven and set the pan on a wire rack. Allow to cool for at least 30 minutes before topping or serving.

As the cake cools, combine butter, brown sugar, heavy cream, and salt in a medium saucepan over medium heat. Stir constantly until butter melts, then allow mixture to come to a rapid boil. Boil for 1 minute. Reduce heat to low, stir quickly, and simmer for 1 minute. Remove from heat and whisk in sifted confectioners' sugar. Allow glaze to cool and thicken for at least 20 minutes before spooning over the cake.

Top with either a dusting of confectioners' sugar or the prepared brown sugar glaze before serving. The cake can be served warm or at room temperature.
