Wash fresh berries and allow to dry completely
Preheat oven to 350 degrees
Spray 3 nine inch round baking pans with cooking spray with flour
Line the bottom of the pans with parchment paper
In a medium bowl sift together the cake flour, baking powder, baking soda and salt. Set aside
I used a stand up mixer but you can use a hand mixer. Start by beating the butter and granulated sugar until nice and fluffy
Beat in sour cream
Now slowly add the flour mixture a little at a time and alternating with the milk .
Beat until everything is incorporated well
In a seperate bowl and using a wire wisk beat the 6 egg whites until very stiff peaks form.
Slowly and carefully fold in egg whites into the cake mixture
Pour the mix evenly into the prepared cake pans
Make sure you give the pans a good tap on a flat surface and wrap the pans with wet cake strips
Bake in a preheated oven for 25-30 minutes or Until the cake springs back and a toothpick comes clean
Cool in pan for 15 minuntes then remove from pan and allow to cool on a wire rack
While cakes are cooling place mixing bowl and wire wisk in the freezer
Once cakes are cooled it's time to make the mascarpone whipped cream
Place mascarponne cheese in the chilled bowl and beat for about 3-4 minutes or until nice and fluffy
Slowly add the whipping cream and beat on medium speed
Once it begins to thicken slowly add almond extract and powdered sugar while beating
Once the mixture starts to thicken turn up to high and beat until very stiff peaks form-this takes 6-8 minutes
Slice several strawberries for in between the layers
Place one cake layer on a plate and spread 1/3 of the whipped cream on it. Generously sprinkly berries of your choice. I only slice the strawberries and leave the smaller berries whole
Repeat until the top layer I place the berries in nice groups
This cake is best served chilled and leftovers need to be stored in the fridge
