Put the morello cherries, red cake icing, and 3 tablespoons sugar in a small saucepan over medium-high heat. Bring to a boil and cook for 2 minutes until thickened. Remove from heat and let cool.
In a bowl, mix the 100g sugar, egg yolk, vanilla sugar, and cream cheese together. In a separate bowl, whip the 400g cream with the cream stabilizer for 3-4 minutes until stiff peaks form. Stir the two mixtures together until combined.
Mix the almond flakes with sugar and toast in a pan over medium heat for 3-4 minutes, stirring occasionally, until golden brown. Remove from heat.
Spoon the cooled cherry mixture into a serving bowl. Spread the cream mixture over the top. Sprinkle the toasted almonds over the cream.
