Preparation
- Step 1
Preheat oven to 350 degrees. Grease two 8-inch by 2-inch-deep round cake pans and line bottoms with parchment or waxed paper. In a bowl, beat together the eggs, ¼ cup sour cream, vanilla and lemon zest.
- Step 2
In bowl of an electric mixer, whisk together the cake flour, ground almonds, sugar, baking powder, baking soda and salt. Beat in butter and remaining ¾ cup sour cream until light and fluffy, 1 to 2 minutes. Slowly beat in the egg mixture until fully combined.
- Step 3
Scrape batter into prepared pans. Bake for 30 to 35 minutes, or until a toothpick inserted in center of a cake layer comes out clean. Let cake layers cool in pans on wire racks for 15 minutes, then invert onto racks and peel off paper. Let cool completely on racks.
- Step 4
While cakes cool, make frosting: In a heatproof bowl suspended over a pan of simmering water (or use a double boiler), whisk egg whites, sugar and salt until sugar is completely melted (130 to 140 degrees on a candy thermometer), 3 to 4 minutes. Remove egg whites from heat; beat mixture with an electric mixer on medium-high speed until completely cooled and thickened, 5 to 7 minutes.
- Step 5
Beat in the butter, a little at a time, until frosting is smooth and fluffy. Beat in the sherry, lemon zest and cinnamon.
- Step 6
To frost cake, place 1 layer on a cake plate, rounded side down, trimming if necessary so it lies flat. Spread with a third of the frosting, top with second layer and frost remainder of cake.

Be wary of the buttercream curdling if your sherry isn't warm enough; when I added my cool (from sitting the in back hall, but not refrigerated) sherry at the noted step, the frosting took on the consistency of messy cottage cheese. It took some Googling and combination of techniques (melting a part of the frosting and beating it back into the curdled remainder + adding confectioner's sugar) to return the frosting (which the internet calls "Swiss Mereingue") to a smooth consistency.
I agree with another review that the frosting is better with less butter- 2 sticks was just right for us. A really delicious cake that we'll make for the family.
The frosting needs a REALLY large pinch of salt, and still has perhaps too much butter as compared to the other ingredients.
This cake is so good, but I have tried four times now to get it perfect. Finally, here’s what I’ve learned. 1) The cake tends toward the dry side. Watch it closely on the oven. It goes from jiggly to overdone in no time. Err on the side of taking it out sooner than later. 2) Make sure all the frosting ingredients are the same temperature, and follow the instructions carefully. I used 2 sticks of butter instead of 3 for the frosting. It could handle another stick if everything is mixed right.
This is a swiss meringue buttercream, but it leaves out the instruction to beat the egg whites until they form stiff peaks. So if your buttercream is runny or curdling, this could be the issue. After the double boiler step, beat on high speed til the eggs form stiff peaks, then another 6 minutes until cool.
Can anyone suggest how to adjust this recipe for 12” round pans? I am hoping to have 14 servings
