A milestone birthday for a very special friend deserves an exciting cake surprise during quarantine. Any cake will do but the birthday girl loves this white cake with French buttercream frosting. This time I added fresh raspberry puree to the frosting. It was tasty.

White Butter Cake
(from The Cake Bible)
*you will need a kitchen scale to best make this cake
4 1/2 large egg whites (135 g)
1 cup milk (242 g)
2 1/4 tsp vanilla (9 g)
3 cups sifted cake flour (300 g)
1 1/2 cups sugar (300 g)
1 Tbs + 1 tsp baking powder (19.5 g)
3/4 tsp salt (5 g)
12 Tbs softened unsalted butter (170 g)
(NOTE: All ingredients must be at room temperature or the cake will not turn out as good as it can.
I have a rectangular baking stone that I place on the rack in bottom third of oven. It heats up with the oven and provides a good hot spot for the cake pans to begin cooking from the bottom up to produce a nice cake.)
Preheat oven to 350 degrees (place baking stone in oven if you have one). Grease three 6" x 3" pans, add a round of wax paper in the bottom of each, then grease and flour pans. (I have also used two 9" x 1 1/2" pans and cooked for the same amount of time)
In a medium bowl lightly combine egg whites, 1/4 cup milk and vanilla.
In a large mixing bowl of stand mixer, combine the dry ingredients and mix on low for 30 seconds. Add the softened butter and remaining milk to dry ingredients. Mix on low speed until dry ingredients are moistened. Increase to medium speed and beat 1 1/2 minutes. Scrape down the sides. Gradually add the egg mixture in 3 batches, beating for 20 seconds after each addition. Scrape down the sides.
Batter will be stiff, scrape batter into prepared pans and smooth the surface with a spatula. Bake 25-35 minutes or until a tester inserted near center comes out clean and the cake springs back when lightly pressed in center.
Let cakes cool in pans on racks for 10 minutes. Invert on wire racks then re-invert so the tops are up to cool completely on wire racks.
Raspberry Sauce
(from The Cake Bible)
2 - 12 oz bags frozen raspberries with no sugar added (680 g)
2 tsp fresh lemon juice
sugar
In a strainer suspended over a deep bowl, thaw raspberries completely. This takes several hours. Press the berries to force out all the juice. There should be 1 cup.
In a saucepan, boil the juice until it is reduced to 1/4 cup. Pour into a lightly oiled heat proof cup.
Puree the raspberries and sieve them with a food mill or press them with the back of a spoon through a fine mesh strainer to remove the seeds. If using a strainer you will press then scrape the bottom of the strainer to get the pulp. It is time consuming. You should have up to 1 cup liquid puree. Add the reduced syrup and lemon juice to the puree and measure. You need to add 1/2 as much sugar as you have in your measuring cup. If you have 1 cup of raspberry sauce then you will add 1/2 cup sugar to create a lightly sweetened sauce.
Raspberry Buttercream
(from
The Cake Bible)
6 large egg yolks (112g)
3/4 cups sugar (150g)
1/2 cup corn syrup (164g)
2 cups unsalted butter, softened (454g)
1/2 cup
Raspberry Sauce
Have ready a greased 2 cup glass measuring cup near stove.
In a bowl of stand mixer, beat yolks with whisk attachment until light in color (don't worry about over-beating). Meanwhile, combine sugar and corn syrup in a nonstick saucepan until combined. Turn heat to medium and stir constantly until sugar dissolves and bubbles begin to form at edges. Stop stirring but continue to heat until rolling boil and large bubbles cover the entire surface. Immediately transfer syrup to glass measuring cup.
Stop mixer, pour a small amount of syrup into yolks and immediately beat at high speed for 5 seconds. Stop mixer and repeat with larger amount of syrup. Continue this process until all syrup has been incorporated. Continue beating until completely cool.
Gradually beat in butter, one tablespoon at a time. Beat raspberry sauce into finished buttercream.
Assemble the Cake
Cut each of the 6" cakes in half horizontally so now you have 6 layers. Take the best looking top cake and set it aside, it will become the top of your finished cake.
Find a round cookie cutter or biscuit cutter or small shot glass or other small round device that you can use to cut through center of your cakes. I found a toothpick holder that was the size I desired - it was 1 1/2" diameter so a good size for a 6" cake. Cut a hole in the center of 5 layers (don't cut a hole in your top layer!).
Place your bottom layer on the cake plate and frost the top, but don't get icing in the hole. Place the next layer on top and continue frosting between each layer trying to avoid getting icing in the hole. Once all 5 layers are iced, create your preferred mixture of sprinkles in a separate bowl - I used some sanding sugar, rainbow sprinkles and some chocolate rainbow chips. Stir the mixture then use a spoon or funnel to pour the mixture in the middle of the cake and fill it to the top. Now add your top layer and finish frosting your entire cake. Decorate the outside as desired. When the cake is cut, all the sprinkles will flow out.
