Rinse the fresh apples, peel, and chop them into small chunks of 0.5 inches. Preheat your oven to 350°F or 177°C. Grease a big 9x13” pan with oil.
In a large mixing bowl, mix the all-purpose flour, baking soda, baking powder, ground nutmeg, cinnamon, allspice, and ginger. Put it aside.
In a separate bowl, stir the applesauce, orange juice, eggs, oil, vanilla extract, brown sugar, and white sugar. Fold the wet ingredients into the dry stuff until incorporated. Stir in 3 cups of chopped apples until combined.
Pour the cake batter into the greased pan, spreading the apple chunks evenly. Smooth the surface and tap the pan on your counter to release any trapped air bubbles.
Bake it in the preheated oven for 45 to 50 minutes. Halfway through, loosely cover it with aluminum foil for even baking. Poke a toothpick in the center of the cake to check its doneness.
Pop the pan out of the oven and place it on a wire rack for at least 30 minutes to cool down completely. You can dust about 2 tablespoons of powdered sugar on top and dig in now.
Mix ¼ cup of unsalted butter, heavy cream, brown sugar, and a pinch of salt in a saucepan. Stir the mixture on a stovetop over medium heat until the butter melts. Let it boil for around 1 minute without mixing.
Switch to low heat, whisk the mix, and let it simmer for another 1 minute. Then, remove the saucepan from the stovetop. Fold in the confectioners’ sugar and let the glaze rest for 20 minutes to cool and thicken. Glaze the warm cake, slice, and enjoy!
