Ingredients

  • 1 (18 1/4 ounce) box yellow cake mix
  • water
  • 3 eggs
  • 1/2 cup vegetable oil
  • 1 (1/3 ounce) box grape Jell-O
  • 3/4 cup grape jelly
  • 1/2 cup butter (1stick)
  • 1 cup peanut butter (crunchy or creamy)
  • 2 1/2 cups confectioners' sugar

Method

  • Preheat oven to 350'F.
  • Grease sides and bottom of 13x9 pan.
  • In large mixing bowl, blend eggs, oil, water and cake mix until blended. Beat on medium speed with mixer about 2 minutes. Pour into pan and bake until done about 25-30 minutes.
  • While cake is baking: boil 1 cup water, remove from heat and stir in Jello until dissolved. Add grape jelly and stir til jelly melted and dissolved.
  • When cake tests done, remove from oven. While hot, poke holes throughout top of cake (I use handle of wooden spoon). Pour grape Jello mixture all over top of hot cake letting mix into all holes. Set aside to cool on rack.
  • In large mixing bowl, combine softened butter, peanut butter, vanilla and salt. With mixer at medium speed, mix about 2 minutes til well blended and somewhat fluffy. Add confectioners sugar 1 cup at a time(stop the mixer to add!) Beat on medium til all sugar is incorporated and consistency is thick frosting. Spread on cooled cake covering entire top with thick layer of frosting. As a finishing touch, I add a TINY sprinkling of salt to top of frosting or crushed salted peanuts.
