Prepare your two 9-inch round cake pans by spraying with cooking oil and lining the bottom with parchment paper.
Make the Cherry Filling
Place the cherries, water, sugar and corn starch into a medium sauce pan. Cook over low heat until the sugar dissolves and the filling thickens. Let cool completely.
Make the White Almond Sour Cream Cake
In the bowl of a stand mixer, combine all of the cake ingredients and mix on low until just combined.
Turn the mixer up to medium for two minutes to allow the ingredients to mix and lighten.
Pour the batter into your prepared pans and bake for 35 - 40 minutes. If you insert a toothpick into the centre of the cake, it should come out clean.
Let the cake cool completely before decorating.
Finish Your Cake
Put the prepared frosting into the bowl of the stand mixer. Whip the frosting for a minute or two to lighten it up.
Spread the cherry filling over the top of one of the layers and sandwich the two layers together. Frost the cake.
