beat egg yolks in a stand mixer for 5 minutes on high
meanwhile cream the butter and sugar, then add the lemon zest, and vanilla products,
add whisked egg yolks and beat well
then beat in the flours
in a clean bowl with clean beaters on your mixer beat the eggs whites until they form soft peaks when you pull away the mixer
add about 1/3 of the mix to the egg yolk and flour mixture, stir to combine
fold the rest of the whites in gently
grease an 8 inch springform pan and line the bottom with a parchment paper circle read the notes to find out what I used because I couldn't BUY an 8 inch springform in my hometown
preheat the broiler on high and move an oven rack 4 inches below it
measure a small portion of batter in the bottom of the prepared pan, spread evenly, shake back and forth and then broil for 2 minutes
remove from the oven, add another bit of batter and broil for 3 minutes making a darker layer
alternate layers until you have used up the batter, you are shooting for TWENTY LAYERS so use the batter sparingly, make a list of layers and check them off to keep track of them--do not over bake your darker layers or your cake will be dry and try to keep them even
once you made 20 layers cool the cake for 5 minutes and then remove from the pan, cool completely
once cool warm and strain the apricot jam then brush over the entire cake, be sure to remove the paper circle first!
