Today I will begin making a Boston Cream Pie because the lobster roll place isn't selling their homemade version any more -- something to do with how messy it is to serve and people complaining -- and because my dad loves anything with ganache all over it. I am looking at this recipe https://preppykitchen.com/boston-cream-pie/ but I do not want a store-style dry fluffy sponge and think I will change the cake out for this which is used as the base for kvæfjordkake or verdensbestekake as it sometimes called https://northwildkitchen.com/kvaefjordkake-worlds-best-cake/
From the original
2 large eggs room temperature
1 cup cane sugar 200g
½ cup whole milk 120mL
5 tablespoons unsalted butter 70g
1 cup all-purpose flour plus 2 tablespoons, 140g
1¼ teaspoons baking powder
¼ teaspoon kosher salt
2 teaspoons vanilla extract
to be replaced with
½ cup (112 g) butter
½ cup plus 2 tablespoons (125 g) granulated sugar
4 large egg yolks
4 tablespoons milk
1 ¼ cup (150 g) all-purpose flour
1 ½ teaspoons baking powder
1 teaspoon vanilla sugar
which has 4 yolks instead of two whole eggs, nearly twice the butter, and, somewhat worryingly, only half the sugar. The 1:1 sugar-to-flour ratio in the original seems like it might be a little excessive, but perhaps there might be a reason for it? He is using bittersweet chocolate, maybe it needs to be offset? The lobster shack puts a decorative swirl of what looks to be simple icing (powdered sugar in milk or water) on theirs, maybe for that reason. I want a robust cake, since the chocolate will harden considerably when cool and pastry cream is plenty sturdy. Any advice would be welcome.
I am also thinking of putting in one of those baking emulsions I learned about from Pye, either Princess Cake or Buttery Sweet Dough, both of which (in addition to vanilla) have a subtle but good high-quality lemony tang, a plain vanilla cake seems like a failure of imagination. Will this gild the lily?

The decorative swirl could also be White Chocolate, I imagine that you could just substitute W. Chocolate for the Reg. Chocolate in your
ganache recipe and use that instead of watery-ass simple icing for the decorative swirl. And, maybe, just maybe use Pastry Flour instead of All-Purpose? This will of course possibly defeat the "sturdiness" you are aiming for... I notice that these Suzy Home-Maker recipes ALWAYS use AP flour in their cake recipes.
That is often a sticking point in my debates with my sister; she is always griping about how her cakes come out too "dense" and that is precisely what she is trying to "fix." She stubbornly refuses to listen to my suggestions about the addition of Cake Flour for a portion of the AP: with subsequent modifications to the amount of leavening if needed in small "test" batches. (In your case, I would whip up a 1 yolk "test batch" using the Flour% method to discover what proportions of everything else to use, bake that off and see if I like the sturdiness/texture etc.)
Typical of a Suzy Home-Maker wimmin, she abandons her original desire to "fix" the recipe because my advice is "too much work." Hah! Then she gets mad when I point out that her logic is circular...
By my reckonning, your second recipe is:
75.66%(72.25%) Butter
83.33%(80.64%) Sugar
45.33%(43.87%) Egg yolks*
40.00%(38.70%) Whole Milk
100.00%(100.00%) AP Flour@150g (Pastry Flour@155g)
4.80%(4.65%) Baking Soda
2.75%(2.75%) Vanilla Sugar
*Large Grade A egg=2oz wt, yolk is about 30% of the egg weight. 1oz=~28g, so 1 Large Grade A Egg Yolk weighs 28g*2*0.30=16.8g
The maths is a bit complicated, there so I will do it for you.
For AP Flour:
27.67g Butter
30.88g Sugar
16.8g Yolks
14.82g Milk
37.06g Flour AP
1.78g Baking Soda
1.02g Vanilla Sugar
For Pastry Flour:
27.67g Butter
30.88g Sugar
16.8g Yolks
14.82g Milk
38.29g Flour, Pastry
1.78g Baking Soda
1.05g Vanilla Sugar
You will notice that the change from
AP Flour --> Pastry Flour COMPLETELY changes the proportions(%) of the other ingredients, but using this method the recipe "stays the same" as far as the final amounts (by weight) present.
Now you can scale that recipe, up/down as needed to make 1000 Boston Cream Pies (full size) or a miniature dainty snack sized one, and the finished product will be the same!
To really achieve this you need to buy yourself a Drug-Dealer digital scale that that can do 0.01g increments.
Probably, you will be obstinate and lazy like my dear sister and say "that's too much work!"
If you are REALLY serious about "sturdiness" of the cake (which I find to be an oxymoronical idear) you could substitute Bread Flour for AP, which I believe is 29g/quarter cup (or 145g Bread flour for your 4-yolk recipe)
Then of course, you could adventure into 100% Cake flour territory (32g/quarter cup? or 160g for 4-yolks.)
I am certain that the above has thoroughly bamboozled you! Maybe, Roz can explain it better and more concisely? Nautical Shore.
Anyway, in short: are you done making that Boston Cream Pie yet? Surely the two hours it took me to write this has afforded you ample thyme.
Now FiX that shit! Ha.
