Heat oven to 350°F (325°F for dark or nonstick pans). Spray 2 (9-inch) round cake pans with cooking spray.
In large bowl, beat all cake ingredients with electric mixer on medium speed 5 minutes, scraping bowl occasionally, until well blended. Pour batter into pans. Bake 35 to 45 minutes or until toothpick inserted in center comes out clean. Cool 10 minutes; remove cakes from pans to cooling racks. Cool completely.
In large bowl, beat butter and cream cheese with electric mixer on medium speed until light and fluffy. Reduce speed to low. Add powdered sugar, 1 cup at a time, beating until blended. Add 1/4 cup liqueur and 1 teaspoon vanilla; beat until frosting is smooth and spreadable.
Place 1 cake layer on serving plate; spread with one-third of the frosting. Top with second layer. Frost side and top of cake with thin layer of frosting to seal in crumbs. Refrigerate 30 minutes. Frost cake with remaining frosting.
