Instructions

  1. Step 1

    Cut the pound cake lengthwise into 6 thin slices, each roughly 1/2 inch thick.

  2. Step 2

    Pour heavy cream into a bowl. Add powdered sugar and vanilla. Whip with an electric mixer until stiff peaks form, about 2 minutes.

  3. Step 3

    Divide whipped cream into 6 small bowls. Add one food coloring drop to each, stirring until evenly tinted.

  4. Step 4

    Place the first cake slice on a plate. Spread 2 tbsp red cream on top, then layer the next slice.

  5. Step 5

    Repeat with orange, yellow, green, blue, and purple cream between each slice, creating a rainbow stack.

  6. Step 6

    Frost the top and sides with leftover cream. Slice and serve immediately for maximum visual impact.
