Banana Sour Cream Cake

18 oz. box yellow cake mix
3 eggs
1 cup mashed ripe bananas (about 3 bananas)
1 cup sour cream
1/4 cup oil
8 oz. pkg. Philadelphia cream cheese, softened
1/2 cup (1 stick) butter, softened
16 oz. pkg. powdered sugar (about 4 cups)
1 cup Planters Walnut pieces, finely chopped


1. Heat oven to 350. Beat cake mix, eggs, bananas, sour cream and oil
with mixer on low until moistened, scraping bottom of bowl often.
Beat on medium 2 minutes. Pour into greased and floured 13x9" pan.

2. Bake 35 minutes or until toothpick inserted in center comes out
clean. Cool cake completely in pan on wire rack.

3. Beat cream cheese and butter with mixer on medium until blended.
Gradually add sugar, beating well after each addition.

4. Remove cake from pan. Carefully cut cake crosswise in half using
serrated knife. Place 1 cake half, top-side down, on plate; spread
top with frosting. Top with remaining cake half; top side up. Frost
top and sides. Press nuts onto sides.


How to Neatly Frost the Cake:
Freeze cake layers about 20 minutes before frosting. This helps to
set the crumbs on the cut edges of the cake layers so they don't pull
up into the frosting. And don't worry if the frosting does not look
perfect on the sides of the cake - the nuts will cover any
imperfections.

Variation How to Prepare in Round Cake Pans
Prepare as directed. Pour evenly into 2 greased and floured 8- or
9-inch round cake pans. Bake 30 to 35 minutes or until toothpick
inserted in centers comes out clean. Cool 10 minutes in pans on wire
rack; remove from pans. Fill and frost with Philadelphia Walnut
Frosting. Store in refrigerator.
