How To Make A Pineapple Cake

Start by warming the pineapple juice in a small saucepan on the stove. Once heated, stir in the oats and let them soak for about 20 minutes, absorbing the juice. Meanwhile, mix the remaining cake ingredients to create your batter. Pour this mixture into an 8×8-inch cake pan and bake for 25 minutes. After baking, allow the cake to cool completely before spreading on the luscious pineapple frosting.

Expert Tips

  1. Proper Mixing: Avoid overmixing the batter to keep the cake light and fluffy.
  2. Check for Doneness: Use a toothpick inserted in the center; it should come out clean.
  3. Cool Completely: Before frosting, ensure the cake is completely cool to prevent melting.
  4. Frosting Consistency: Drain the crushed pineapple well for the perfect frosting consistency.

    Where in the recipe is the powdered sugar incorporated? I assume with the frosting. I didnโ€™t see it in the directions.

    1. Joanie Zisk says:

      You’re absolutely right, and I appreciate your patience. I did leave that out initially, but itโ€™s been corrected now. The powdered sugar should be added while making the frosting. Thanks for catching that!

  2. Diane L says:

    Can I use old fashioned oats as long as I soak as directed?

      Hi Diane, I have not made this cake with old fashioned oats but I think it should work.
