A Birthday Cake to End All Birthday Cakes

Welcome to Wolf Chops, Thanksgiving Edition! In honor of the holiday, I present you with a guest post from my sister, describing the birthday cake she made me six months ago. But it's utterly excessive, so frankly I think it fits with the whole spirit of Thanksgiving, and it includes roughly 3 sticks of butter, which is almost the same as oil, so bam, Hannukah too. This recipe is picky, and time-intensive, and a crap-ton of work, and absolutely one of the best sweets I've ever eaten. And I now fresh apricots are basically impossible to find right now, but I don't see why you couldn't make the pastry cream with, say almonds or walnuts or pecans instead of pistachios and then put some cinnamon-poached apples or pears on top instead for something seasonal. Or roasted chestnut and quince. Or pumpkin pie filling. Whatever. It's more or less just a giant croissant with fruit and cream on top, so you can do what you like. Yes, it will have a million calories and take all day, but a) it's the holidays so it'll fit right in and b) worth it! So without further ado, Sarah's Insane Giant Croissant Cake. 


Pretty, ain't it?
***
Each year, I have to top the last birthday cake I made for Emily. Last year, I made a beautiful peach blueberry tart (pictured above in the sidebar). (EAG: That was a damn tasty tart.) Emily gave the in inspiration for my cake in April. She texted me a picture of a pistachio apricot danish that she gets at a local farmers market. She kept raving about that pastry, so I decided to make a variation of that. 

My first question was what to use a base. I wanted something denser than a cake. Emily suggested making a crust with almonds (EAG: gluten free so Mom could eat it!), but that was too close a tart crust. Then it came to me: I should base the crust on croissants I had experiment with making croissants last fall, and had found a really good recipe. The croissant dough would be similar to the danish base, but even better.

The tart that started it all...

There are basically three stages for making croissants. The first step is making the dough. You melt butter, add some milk, and once the butter dissolves and the temperature of the milk is below 90`F, you mix in the yeast. You then combine the milk mixture with flour (preferably King Arthur all purpose flour; it has the best protein content), sugar and salt in a mixer with a dough hook. The dough should form a slightly sticky ball. The dough then rests in the fridge on a parchment-lined baking sheet overnight.

While the dough was resting I tackled the pistachios. My first thought was to make a pistachio-flavored pastry cream, using pistachio extract, but that would be too close to last years’ again. Then I came across a recipe for "Snow Eggs in pistachio cream" in the Gourmet Cookbook. To make the pistachio cream, you grind the pistachios in a food processor with a little milk, and then refrigerate the mixture for at least 8 hours to develop the flavors. I originally made one batch of this, but it was so yummy, I made another.

The second stage or croissant making is laminating the dough. You beat butter into an 8" x8" block, then place the butter in the middle of the croissant dough, that has been rolled out to 24"x8". You then fold the dough over the butter block and seal it in the dough. Then you roll the dough out to 8"x24" again, and then fold the dough in thirds, like a letter. You repeat the rolling out and folding a couple more times (at least 3, I did 5), to layer the butter between the layers of dough. After it was laminated, the dough had to rest in the freezer for 2 hours. 

Decorating the tart.

While the dough was resting, Emily and I tried one of the apricots that had been bought for the cake. They were very tart and mealy. To improve the flavor and texture, I decided to roast the apricots with vanilla. I had hoped that it would add more sweetness, and the vanilla would mellow the tartness. After they were done roasting, they still weren't quite sweet enough, so I finished them off under the broiler, with a little vanilla sugar sprinkled on top. At this point, they were still quite tart, but the tartness was no longer overwhelming.

After the dough had rested for 2 hours, I rolled it out until it was about 1/4" thick at the center. I then draped the dough into a tart pan and molded the dough to the edge of the pan. Because the cake is a riff on a cheese Danish, I rolled 1 inch of the excess dough in to create a rolled edge. In hindsight, I should have painted the excess dough with the pistachio cream before rolling it, to break up the monotony of the huge crust. I set a straight-sided bowl in the middle of the giant Danish to stop the dough from rising too much and obliterating the center depression, and left it to rise for 2 hours.

An hour and a half later, I preheated the oven to 425`, and took the bowl out of the center of the Danish. I then painted the Danish with a basic egg wash, with a little extra sugar. When the oven was preheated, I put the Danish in and immediately lowered the heat to 400`. The Danish baked for 15 minutes, when it was nicely puffed and golden brown.

To assemble the cake, I spooned the pistachio cream into the depression, the draped the apricots on top. The blackberries were placed around the apricots, along with some almond slivers. The final step was to eat it. And it was very tasty. (EAG: Damn straight.)

By the slice.

Apricot-Pistachio Danish Cake
Croissant dough:
3tablespoons unsalted butter plus 24 tablespoons (3 sticks) unsalted European-style-butter, very cold
1 3/4cups whole milk
4teaspoons instant or rapid-rise yeast
4 1/4cups (21 1/4 ounces) all-purpose flour
1/4cup (1 3/4 ounces) sugar
2 tsp salt
1large egg
1teaspoon cold water

Pastry cream:
1/2 cup shelled pistachios
2 tbsp sugar
7 tbsp of whole milk

Roasted apricots:
7 apricots
1/2 vanilla bean, seeded
1 cup white wine
1/4 cup vanilla sugar 
Slivered almonds

Egg wash:
1 egg
1/4 cup sugar
Dash of salt
Dash of water

Optional:
Fresh blackberries

Slivered almonds, after being roasted with the peaches.

1) Melt 3 tbsp butter in over low heat. Take of the heat and immediately stir in the milk. Let cool til the temperature is under 90’. Whisk in the yeast, and pour it all into a stand mixer. Add flour, sugar, and 2 teaspoons salt, then knead on low speed using the dough hook roughly 2-3 minutes, until dough forms. Up the speed to medium-low and knead for another minute. Cover the bowl with plastic wrap and let it rest on the counter for half an hour.

2) Line a rimmed baking sheet with parchment paper dump in the dough. Shape it into a 10-by-7-inch rectangle, about an inch thick. Wrap tightly with plastic and stick in the fridge for 2 hours.

3) Meanwhile, fold 24-inch length of parchment paper in half to create 12-inch rectangle. Fold the 3 open edges over to form an 8-inch square with enclosed sides. Crease the folds firmly. Place 3 (sliced) sticks of cold butter directly on the counter and whack them with rolling pin for a minute or so until the butter is just pliable but not yet warm, then fold butter in on itself using bench scraper. Beat it into rough 6-inch square. Unfold your parchment envelope. Using the bench scraper, transfer the butter to the middle of the parchment, then refold it enclose. Turn the packet over so that the flaps are underneath, and gently roll with the rolling pin until the butter fills parchment square, making sure it’s even. Refrigerate at for least 45 minutes.

4) Put the dough in the freezer for half an hour, then lightly flour your counter and roll the dough into 17 by 8-inch rectangle with the long side along the edge of the counter. Unwrap the butter from the parchment and place it in the center of the dough. Fold the sides of the dough over the butter so they meet in the center, and press the open edges together so they seal. Roll the butter/dough package out lengthwise into 24 by 8-inch rectangle. Starting at the bottom of the dough, fold it into thirds like a business letter. Turn the dough 90 degrees, then roll it out lengthwise again into 24 by 8-inch rectangle and fold into thirds again. Place the dough on your cookie sheet, wrap it tightly with plastic, and put it back in the freezer for another half hour.

5) Put the dough back on your lightly-floured countertop so that the top flap opens on the right. Roll the dough out lengthwise into a 24 by 8-inch rectangle and fold into thirds (yet again). Place the dough back on the sheet, wrap it tightly with plastic, and refrigerate it for yet another 2 to 24 hours.

6) Make the Pistachio Cream: Finely grind the pistachios in a food processor with the sugar. Add 2 tbsp of milk, and grind until it forms a paste. Add the remaining 5 tbsp of milk and mix in the food processor until well combined. Transfer the cream to a bowl and refrigerate for a few hours to develop the flavors.


Pistachio cream (can also be eaten straight with a spoon).

7) Shape the Crust: Remove the Croissant dough from the refrigerator and roll it out until it’s about 1/4" thick. Drape the dough in a tart pan, so that there is a least an inch of excess dough all around when the dough is molded to the sides of the pan (trim off any extra excess dough to use/eat later). Paint a little of the pistachio cream on the excess dough. Roll the excess inch of dough to make a Danish-like edge to the tart. Place a buttered bowl with straight sides in the middle of the pan to keep the dough from rising in the center, and let the dough rest of 2 hours.

8) Prepare the Apricots: Preheat oven to 400`. Slice each apricot into 4 flat slices with parallel cuts and place them in one layer in a baking pan. Scatter a handful of slivered almonds. Mix together 1 cup of white wine, the vanilla seeds, and 2 tbsp vanilla sugar. Pour the mixture over the apricots, and place the vanilla bean pod in the pan. Roast for 30 minutes, or until most of the liquid is gone. Put aside and let cool.

Apricots, pre-roasting.

9) Preparing the Crust: Raise the oven temperature to 425`. After it has sat for at least 2 hours, remove the bowl from the croissant crust. Combine the egg, sugar, and a dash of salt with a dash of water, and mix until well combined. Paint the croissant crust with the egg wash.

10) Bake the Crust: Place the croissant crust in the oven and immediately turn down the oven's heat to 400`. Bake the croissant tart for 15 minutes, or until golden brown. The dough will puff up a lot. Remove from the oven and let cool. 

Final assemblage.

11) Turn the oven to broil. Sprinkle the apricots with the rest of the vanilla sugar, and broil them, just until they begin to brown. (Keep watch so they don’t go up in flames!) Take them out of the oven and let them cool.

12) Assembling the cake: Spoon a quarter cup of pistachio cream into the center of the croissant crust, and spread it evenly. Cover the cream with the broiled apricots. Place the slivered almonds and blackberries on top of the apricots prettily. Add candles, sing happy birthday, and bask in the adulation of everyone there.
