Ingredients For This Keto Pineapple Upside-down Cake

You can find all ingredients for this delicious keto cake at your local grocery store or order them online. You will be impressed that such a fancy cake requires only a few easy ingredients.

Ingredients Keto Pineapple Upside-Down Cake

For The Bottom Layer

  • Butter – make sure you use unsalted butter at room temperature to mix well.
  • Brown Sweetener –The best sweetener for replicating granulated brown sugar is brown sugar replacement with allulose.
  • Pineapple – You can use either fresh or canned pineapple.
  • Raspberries – Fresh ones are the best, but you can also use frozen ones.

For The Cake Batter

  • Almond & Coconut Flour – This cake recipe is made with almond flour and coconut flour, complementing each other and providing a light and fluffy texture.
  • Butter – always unsalted butter, and if you want a dairy-free option, you can use coconut or avocado oil instead.
  • Sweetener – I used powdered Erythritol for this recipe, but Monk Fruit sweetener or Allulose would also work.
  • Eggs – to avoid that eggy taste, make sure you use room-temperature eggs.
  • Almond Milk – It gives moisture to baked desserts and is perfect for dairy-free baking.
  • Vanilla Extract – make sure you use the best quality vanilla extract you can find.
  • Baking Powder – This ingredient helps the cake batter rise and become fluffy.
  • Salt – helps to enhance all the flavors.

How To Make This Delicious Keto Pineapple Upside-down Cake

This recipe may look too fancy, but you’ll be surprised to see how easy it is to make it. Here is everything you have to do:

Mix the softened butter and brown sugar substitution until light and fluffy. Then line the bottom of the baking pan with parchment paper and add the butter mixture. 

Cut the pineapple into thin slices and as evenly as possible. To cover the entire bottom of the tray, you can cut the last two pineapple slices in half, then place a raspberry in the center of each pineapple slice.

Making The Cake Batter

Add all the wet ingredients to a mixing bowl and mix them for about two minutes.

Then add the dry ingredients and mix them well.

Now you can add the butter and mix until everything is well combined.

Baking The Cake

Pour the cake batter over the pineapple slices and bake in the preheated oven for about 40 minutes.
