Sheet Pan Zucchini Carrot Cake

Step 1
Preheat the oven to 350 degrees F (175 degrees C). Grease a large, rimmed baking sheet with butter.

Step 2
Combine flour, coconut, baking powder, and salt in a bowl.

Step 3
Combine butter, sugar, and vanilla sugar in a large bowl; beat with an electric mixer until very smooth and creamy, about 5 minutes. Add eggs one at a time, and beating well after each addition. Fold in zucchini and carrots.

Step 4
Stir in flour mixture alternately with milk until batter is well combined. Spread onto the prepared baking sheet.

Step 5
Bake in the preheated oven until a toothpick inserted into the center comes out clean, about 45 minutes. Pour orange juice over warm cake immediately after removing from the oven, so it can soak up the liquid.
