Pineapple Cake

Lightened Up Pineapple Cake

Jump to Recipe

I’m in my pineapple era, it’s so good right now! Nature’s candy! This cake is so easy and so delicious! You’d never know it is lightened up! Topped with a whipped cream and cream cheese frosting, it is a dream! It is super light and so perfect for summer!

The cake is super moist too, due to the crushed pineapple in the mix. Using fruit puree or crushed fruit instead of butter is a great way to keep cakes moist without all the fat. It is an easy swap you can use to lighten up your desserts.

I used a 20 oz can of pineapple and just used half of it. You can do the same, or you can double the rest of the ingredients to make a larger cake! You can also probably get away with an 8 oz can.

Here is what you will need:

  • Flour – all purpose
  • Protein Powder – vanilla is what I used. You can also sub with 1/4 cup more flour
  • Crushed Pineapple
  • Egg
  • Sugar Substitute – I always use Lakanto brand (you can shop my link for 15% off)
  • Reduced Fat Cream Cheese
  • TruWhip Whipped Topping – my fave, no weird ingredients
