Preheat your oven to 350°F (175°C) and grease a 9-inch baking pan to prepare for baking.
In a large mixing bowl, whisk together the sifted flour, ground cinnamon, ground ginger, baking powder, and salt until evenly combined. This creates the dry base for the batter.
In another bowl, beat the eggs and granulated sugar with a whisk until the mixture is smooth and slightly frothy, about 1-2 minutes.
Stir in the melted butter, vanilla extract, and apple cider into the egg and sugar mixture until well combined. The mixture should be glossy and fragrant.
Fold the wet mixture into the dry ingredients using a spatula, mixing until just combined; avoid overmixing to keep the batter tender.
Gently fold in the chopped apples until evenly distributed throughout the batter, which will look slightly thick and speckled with apple pieces.
Pour the batter into the prepared baking pan and smooth the top with a spatula for even baking.
Bake in the preheated oven for 40-45 minutes, or until the cake is golden brown on top and a toothpick inserted in the center comes out clean.
Once baked, remove the cake from the oven and set on a cooling rack; allow to cool for at least 15 minutes to set properly.
Slice the cake and serve warm or at room temperature, enjoying the moist crumb speckled with tender apple pieces and fragrant spices.
