Easy Orange Cake 2.5 to 3.5 hours This is very nice with an orange butter icing sweet butter whipped with confectioners' sugar and orange juice concentrate to which has been added 1 tablespoon of grated fresh orange rind. To Cook: Place the cake mix, orange juice, and eggs in a large bowl and beat by hand 300 times. Add the grated rind for the last round of beating. Pour the batter into a wellgreased-and floured 2 litre mold or spring-form pan. Place the pan in the slow cooker and cover with a loosely fitting plate. Cover the pot, but prop the lid open a fraction with a toothpick or a twist of foil to let excess steam escape. Cook on High for 2.5 to 3.5 hours. When a toothpick inserted in the center of the cake comes out clean, the cake is done. Cool on a rack for 10 minutes before turning the cake out of the pan. Makes 10 to dozen servings.
