½ to 2 teaspoonsmilk(add more or less to reach the right consistency)
Instructions
PREPARE THE CAKE:
Preheat the oven to 350 degrees F. Butter and flour a bundt cake pan (or spray with baking spray).
In a large bowl, whisk together the flour, granulated sugar, brown sugar, cinnamon, baking powder, salt, nutmeg and baking soda.
In a medium bowl, whisk together the oil, milk, and eggs.
Stir the wet ingredients into the dry (being careful not to over-mix), and then fold in the shredded apple.
Pour the batter into the prepared pan and spread it out evenly. Tap the pan a couple times on the countertop to get rid of any bubbles. Bake until a toothpick inserted in the center comes out clean, about 1 hour (start testing at about 50 minutes). Cool completely.
MAKE THE ICING:
Once the cake has cooled, add the cream cheese, powdered sugar, and vanilla to a large bowl and use a handheld electric mixer to beat until combined. Beat in enough milk ½ teaspoon at a time so it reaches your desired consistency. It should be thick, somewhere between buttercream and a pourable glaze.
Run a paring knife between the cake and the inside of the pan to help loosen it. Turn the cake out onto a cake plate. Drizzle the icing decoratively on top.
