Vegan Carrot Cake Sheet Cake

Perfectly moist and studded with raisins, this vegan carrot cake is sweetened with dates and banana and gets its rich flavor from cinnamon, nutmeg, cloves, and vanilla. A blender is used to grind the oats into a flour and combine the liquid ingredients, then the batter is mixed by hand to avoid overbeating. No need to peel the carrots before shredding them—just give them a quick wash to remove any dirt or grit. The cake will keep for up to five days and tastes even better the day after it’s made. It also freezes well. Spread with Vanilla Bean Frosting or serve on its own.INGREDIENTS
1½ cups unsweetened plant milk, such as almond, soy, cashew, or rice
4½ ounces pitted whole dates, chopped
¾ cup raisins, divided
½ cup sliced ripe banana
1 teaspoon pure vanilla extract (or seeds from 1 vanilla bean)
1¾ cups regular rolled oats
2 teaspoons baking powder
2 teaspoons ground cinnamon
1 teaspoon baking soda
1 teaspoon ground nutmeg
Pinch of ground cloves
1½ cups finely shredded carrots
½ cup chopped walnuts (optional)
1 cup Vanilla Bean Frosting (optional)
Combine the plant milk, dates, ¼ cup of the raisins, the banana, and vanilla in a medium bowl. Let stand for 15 minutes or until dates are softened.
Preheat the oven to 350°F. Line an 8-inch square baking pan with parchment paper (or use a silicone baking pan).
Place the oats in a blender. Cover and blend until a powder forms. Transfer to a large bowl. Stir in the baking powder, cinnamon, baking soda, nutmeg, and cloves.
Transfer the date mixture to the blender. Cover and blend until smooth. Add the date mixture to the oat mixture in bowl; stir just until combined. Fold in the remaining ½ cup of raisins, the carrots, and walnuts (if using).
Spread the batter into the prepared baking pan. Bake for 40 to 45 minutes or until golden. Cool in the pan for 10 minutes. Remove from the pan; cool on a wire rack. Spread the cake with Vanilla Frosting (if using).
