How to Make Surprise Rainbow Pi Cake

  1. Preheat oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan.
  2. In a large bowl, cream together the butter and sugar until light and fluffy.
  3. Beat in the eggs one at a time, then stir in the lemon zest and vanilla extract.
  4. In a separate bowl, whisk together the flour, baking powder, and salt.
  5. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
  6. Divide the batter into five bowls. Add gel food coloring to each bowl (red, orange, yellow, green, blue/purple).
  7. Create the Pi symbol in the prepared pan by carefully spooning the colored batters into the desired shape to form a Pi symbol. Fill any remaining space with the batter.
  8. Bake for 50-60 minutes, or until a wooden skewer inserted into the center comes out clean.
  9. Let the cake cool in the pan for 10 minutes before inverting it onto a wire rack to cool completely.
  10. Dust with powdered sugar or drizzle with a lemon glaze before serving.
