Mixed Berry Cake Filling

A versatile Mixed Berry Cake Filling you can use for a multitude of desserts. Goes great in a layered white cake.

I was recently watching an episode of the Great British Baking Show saw where Mary Berry made a cake with a Mixed Berry Cake Filling.

Fortunately, I had to make a cake for a birthday party and wanted to do something a little different. I really wanted to make a 2 layer cake with some mixed berries between the layers.

Needless to say, I tried to memorize what she did but unfortunately, I did not get her exact recipe. That being said, I did get enough details from her that I was able to come up with this delicious berry filling for a layered cake.

While this recipe calls for mixed berries, you could easily substitute for any type of frozen berries using the same process.

This Mixed Berry filling goes great with my Perfect White Cake. And if you are in need of a great frosting for your cake, make sure you check out my Boiled Icing recipe.
