Instructions

  1. Step 1

    Whip softened butter and powdered sugar with an electric mixer until fluffy, about 90 seconds.

  2. Step 2

    Add heavy cream and beat until smooth. Divide buttercream into 4 bowls and tint each a different color with food coloring.

  3. Step 3

    Spread a thin layer of colored buttercream on one pancake. Stack another pancake on top and spread with a different color.

  4. Step 4

    Repeat, alternating colors, until all 8 pancakes are stacked into a tall rainbow tower.

  5. Step 5

    Frost the outside of the stack with remaining buttercream in rainbow stripes if desired, then top with sprinkles.

  6. Step 6

    Slice with a sharp knife dipped in hot water between cuts for clean rainbow layers. Serve immediately.
