Is that time of the year again, when the blackberry bushes are in full bloom, and we pick a handful every time we step out the house, just like we do every season.
I choose to bake a plain sponge cake and fill it with blackberry cream this time. The lemons came into the picture in form of lemon syrup which I drizzled generously on top of each cake layer, and also used in the frosting. Funny how a blackberry cake turned out to be pink, but there’s no secret to it, the magic was to simmer/boil the fresh blackberries with lemon juice for a few minutes and they turned from black to beautiful red.
When I finished this cake and my son first tasted it, he pulled all sorts of faces to me, then pushing his plate away he said “Mom, this is the most disgusting cake I ever had!” Pff…..that bold honesty put me off a little bit, and when tasting it myself I almost fell for it, but after leaving an almost untouched, full cake in the fridge over the night (which never happened before in this kitchen), the next morning our disappointment turned into amazement and now I can say that this is the kind of cake which is best to leave to rest and chill in the fridge for at least 6-8 hours before eating (must be the cream cheese!). Surprisingly the next morning this cake was wonderful, the flavours of the lemon and sweet blackberry combined and even my son’s face lit up with happiness and he finally had a slice of cake that he could enjoy.
-6 eggs at room temperature, separated
-6 Tbsp granulated sugar
-6 Tbsp all purpose flour
-1 tsp baking powder
-1 tsp vanilla extract
-pinch of salt
-3/4 cup water
-1 Tbsp granulated sugar
-4 Tbsp fresh lemon juice (about 1-2 smaller lemons)
-3 cups powdered sugar
-375 g butter at room temperature
-1 pack Mascarpone cream cheese
-300 g fresh blackberries (but take away 1 cup to place them between the cake layers)
-2 Tbsp fresh lemon juice (1 lemon)
-1/2 tsp salt
Preheat the oven. Line the bottoms of two 8″ cake pans with baking paper, no need to grease.
In the bowl of the electric mixer fitted with whisk attachment, beat the egg whites with the sugar until you get a firm, shiny peak. Now gradually add the egg yolks, one at a time and the vanilla extract.
Mix the flour, salt and baking powder. Add the flour mix to the egg cream, but very gently and using only a large spoon until everything is combined. Evenly divide the batter into the cake pans and bake for 25-30 minutes.
Remove from the pans by sliding a thin spatula or knife around the edges then transfer to a wire rack, remove baking paper from the bottom. Let it cool completely, then cut both cakes in two equal layers.
Put 1 cup of blackberries with 2 Tbsp fresh lemon juice in a small saucepan. Simmer for a few minutes until they go red and soft. Strain through a fine mesh strainer, pushing the blackberries through with a wooden spoon until only seeds are left in the strainer. Discard seeds, and put the gained puree aside to cool down completely. There should be about 5 Tbsp puree.
In a bowl of the electric stand mixer fitted with whisk attachment, start whipping the butter slowly with the powder sugar and salt (this is the part I hate because I just can’t do it without my kitchen ending up all dusty….). Increase speed to high and beat until white and fluffy.
Add the cream cheese, a Tbsp at a time and mix until well combined, then whipping 2-3 more minutes until fluffy again, scrapping down the bowl as needed.
Drizzle in the cooled blackberry syrup 1 Tbsp at a time then beat another minute. If you think it’s getting too soft or started to curl, then add more powder sugar and 1 Tbsp of butter.
Make the lemon syrup by combining the lemon juice with the sugar and water in a saucepan on the stove. When it gets hot and started to simmer, take it off and start drizzling the syrup directly on the cake layers. Let it cool for a few minutes before filling your cake with the cream.
After each addition of blackberry cream, put a few blackberries before stacking with another layer of cake. Finish off with generous amount of ream to the sides and lighter layer of ream on the top. I made few rosettes (which by the way are far from perfect, but just can’t seem to master this technique….. 🙂 )
