For the cake:

  • 1 cup unsalted butter (room temp)
  • 1 8 oz pkg. cream cheese (room temp)
  • 2 tsps clear vanilla extract (or regular vanilla extract if you don't have clear)
  • ¼ teaspoon almond emulsion (optional)
  • ½ tsp. lemon extract
  • 6 egg whites
  • ¼ cup vegetable oil (or canola oil)
  • ⅓ cup milk
  • ¼ cup water
  • 1 3.4 oz. pkg. white chocolate instant pudding mix (dry)
  • ¼ cup all purpose flour

  • pinch of salt

Instructions

For the cake:

  • Preheat oven to 325 degrees. Grease and flour a 10″ bundt pan very well.
  • Mix butter, cream cheese and extracts very well until completely smooth.
  • Add in the rest of the ingredients and mix on medium to medium/high until well incorporated. The batter will be thick.
  • Stir in the rainbow jimmies.
  • Add to prepared pan and smooth the batter even.
  • Bake at 325 for 60-65 minutes.
  • Cool in the pan on a wire rack for about 20 minutes, then turn out of the pan onto the wire rack and cool completely before adding a glaze or powdered sugar.

For the glaze:

  • In a mixing bowl, add in the confectioners sugar, extract, milk and pinch of salt. Mix well until smooth.
  • Check the consistency. If it's too thick for drizzling, add more milk or cream by tablespoon until desired consistency. If it's too thin, add in another cup of confectioner's sugar.
  • Drizzle over cooled cake.
