1 pkg. yellow or white cake mix
1 (16 oz.) pkg. frozen strawberry halves, thawed
1 lg. box vanilla pudding (sugar free, instant)
Cool Whip or 1 carton chilled whipping cream + 1/4 c. sugar

Bake cake in oblong pan as directed on package. Cool. Only use half of cake for these ingredients, or you can double strawberries and pudding. Cut cake into squares, then split squares horizontally. Line a bowl with half of squares, cutting pieces to fit bowl. Pour half the strawberries, with syrup, over cake. Spread with half of the pudding. Repeat with remaining cake pieces, strawberries and pudding. Cover; chill at least 4 hours. Top with Cool Whip or whipping cream.
