Whip heavy cream with powdered sugar until stiff peaks form, about 2 minutes.
Step 2
Divide whipped cream into 4 bowls. Add 2-3 drops of gel food coloring to each bowl, one color per bowl. Stir to combine.
Step 3
Place first cake layer on a cake stand or plate. Spread a thin layer of red whipped cream on top.
Step 4
Stack second layer on top. Spread with orange whipped cream. Repeat with third layer and yellow cream, fourth layer and purple cream.
Step 5
Frost the sides and top with remaining white whipped cream, creating a smooth finish.
