Vegan Raspberry Fluff Cake

September 29, 2025 By Gretchen

Jump to Recipe Print Recipe

Valentine’s Day or not
This Vegan Raspberry Fluff Cake will have you falling in love!

Aptly named for the thick fluffy layers of vanilla cake and raspberry buttercream!
Bonus: It can also be made gluten free! *see notes below

Today it is all natural colors for this Vegan Raspberry Fluff Cake

By using raspberry puree for the buttercream instead of food color!

Notes for Success:

Typically I make 3-7″ layers but today I baked my batter into 6″ cake pans  for a really impressive four layer cake
For those who only have 8″ pans you can simply divide the batter between those 2 pans for  a tow layer cake instead

The rule of thumb is to fill the pans slightly more than half full to give the batter room to rise and bake properly

Probably the biggest reason for cake batter failure besides measuring errors is that people tend to over fill the cake pans
Which will leave you with an improperly risen cake, resulting in a heavy dense crumb

For the buttercream recipe I’ve added  raspberry puree at the last stage of mixing
But I have also used freeze dried fruit powder for an even easier and more delicious raspberry buttercream!

Prep Time 2 hours hrs
Cook Time 30 minutes mins
Total Time 2 hours hrs 30 minutes mins
Servings 6

Ingredients
  

  • 1 Recipe Yellow Cake
  • 1 Recipe American Buttercream
  • Raspberries fresh or frozen 2 cups
  • OR 1.75 ounce freeze dried raspberry powder

Instructions
 

  • Grease & parchment line your 4-6" cake pans & preheat the oven to 350°
  • Prepare the cake recipe & buttercream as per the instructions on those blog posts
  • While the cakes are baking, prepare the raspberry puree for the raspberry fluff buttercream, unless you are using freeze dried raspberry powder in which case you will just add that at the last stage of mixing your buttercream
  • For the Compote: It's easier to use frozen raspberries because they break down faster & you don't have to add any liquid for the cooking process, but if you are using fresh berries ~ add a few tablespoons of water to help them cook down.
  • You can add sugar if you like but since I am adding this to already super sweet buttercream, I am using only the raspberry puree
  • Let the berries cook over a low heat until they breakdown completely stirring often. This should only take about 20 minutes.
  • Strain the puree through a sieve, discard the seeds & fibers and once the puree is cold add it to the buttercream recipe at the last stage of mixing
  • Once the cake layers are cooled, assemble the cake with the raspberry fluff buttercream filling & icing & decorate as you like
