Prepare the cake batter according to the instructions on the package, combining eggs, water, and oil as directed.

Divide the prepared batter into three equal parts. Leave one portion white, tint one portion with red food coloring, and the third with blue food coloring. Mix thoroughly to create distinct colors.

Using spoons, alternately drop spoonfuls of each colored batter into the bottom of the greased dish, leaving space between each color. Continue layering randomly until all batter is used. Tap the dish gently on the counter to level the surface. Lightly swirl the colors with a toothpick to create a marbled effect without mixing them together.

Bake the cake according to the timing on the package instructions. Allow to cool for approximately 10 minutes at room temperature.

In a mixing bowl, whisk instant cheesecake pudding mixes with milk until smooth and just beginning to set. Pour the pudding mixture over the cooled cake, pressing gently to ensure the pudding fills the poke holes. Smooth remaining pudding on top. Refrigerate until fully set.

In a chilled bowl, beat the heavy cream and vanilla extract until soft peaks form. Gradually add powdered sugar and continue beating until stiff peaks form. Spread whipped cream evenly over the chilled pudding layer.
