Preheat the oven to 350F (180C). Grease and line a 8 inch (20cm) springform pan with parchment paper.
In a bowl whisk eggs with sugar until well combined. Incorporate oil and rum extract. Sift the flour, salt and cocoa powder and whisk to fully incorporate.
Pour the batter into the prepared pan.
Add the pitted cherries on top and bake for 15-20 minutes until a toothpick inserted into the center comes clean or with a few moist crumbs attached.
Let cool completely.
Prepare the vanilla ice cream.
In a large bowl whip cream until stiff peaks form. Mix in the sweetened condensed milk and vanilla extract until well combined. Fold in the mini chocolate rocks.
Transfer the cake onto a serving platter.
Add a cake ring around the cake and line with an acetate sheet.
Pour the ice cream mixture over the cake. Smooth the top. Freeze for 6 hours or overnight to set completely.
Prepare the cherry coulis for serving.
Place the cherries, sugar and lemon juice in a small saucepan and place over medium heat, bring to a boil and cook for about 5 minutes. Remove from heat and purée with a blender.
Strain through a fine-mesh strainer and let cool.
Before serving decorate the cake with fresh cherries and chocolate decorations and serve with cherry coulis. Enjoy!
