We're Having a Heat Wave

I grew up in Nebraska, where it was not unusual for it to reach 100 degrees in the summer.  There's a song my mother used to sing:  "We're having a heat wave, a tropical heat wave."  Anyone know that song?

Flash forward twenty years, where it hit 75 degrees in Anchorage on Sunday night and the air was thick and humid in preparation for some serious rain.  Mosquitoes swirled about the yard and David and I started to complain about how hot it was.  So what did we decide to do?  Run the oven cleaner.  The temperature on the lower level of the house rose another ten degrees.  (In my defense, I'm not a total whiner.  This inability to handle heat happens to everyone who moves to Alaska.  I lived in New Orleans for four years, and I once lived in an apartment in St. Paul, Minnesota with no air conditioning and the temperature regularly hit 95-100 that summer).

So of course I decided to frost a cake.  Seriously intelligent move.  I had to move the cake out of the kitchen to prevent frosting from melting down its sides.

I'm back on schedule with the Cake Slice group this month, after having been on vacation for May's cake pick.  In the interest of full disclosure, this cake should have a layer of pudding between the two layers.  This pudding, logically enough, required heavy cream.  And here is the joy of living in Alaska:  the large, normally decently-stocked grocery store near my home had no heavy cream on Sunday afternoon.  Zip.  None.  Nada.  So I doubled the frosting and skipped the pudding.

Omitting that step saved a lot of time, and judging from the comments of some of my fellow bakers, some serious angst;  apparently it was hard to keep the layers from sliding when the pudding was sandwiched between them.

This version requires less than an hour of active time, and is seriously, deeply chocolatey, not too sweet and with just a hint of coffee.   Even though I'm not much of a chocolate person (gasp!), I loved it. 

Brooklyn Blackout Cake

Adapted from The Cake Book by Tish Boyle

For the cake:

1 1/2 cups all-purpose flour

1 cup dark cocoa powder

1 1/2 tsp. baking powder

1 1/2 tsp. baking soda

1 tsp. salt

1 3/4 cups granulated sugar

2 large eggs

1 egg yolk
1 cup buttermilk
1/2 cup unsalted butter, melted
2 tsp. vanilla
1 cup hot brewed coffee (I used a Starbucks Via packet in 8 oz. of hot water--worked like a charm)

For the frosting:
8 oz. unsweetened chocolate, roughly chopped
22(!) tbsp. unsalted butter, softened
3 cups powdered sugar
4 tsp. vanilla

Position a rack in the center of the oven and preheat it to 350 degrees.  Spray two 9-inch cake pans with baking spray with flour and set aside.

Sift together the flour, cocoa, baking powder, baking soda and salt into the bowl of your stand mixer, if you have one, or a large bowl if you're using a hand mixer.  Whisk in the granulated sugar and set the bowl on the stand mixer.

Whisk together the eggs, egg yolk, buttermilk, melted butter and vanilla in a medium bowl.  Put the stand mixer (or hand mixer) on low speed and slowly drizzle the wet ingredients into the coca mixture.  Scrape down the sides of the mixing bowl and ensure that it is well-mixed.  Then add the coffee, mixing until just blended.

Using a spatula, fold the mixture together to ensure that the ingredients on the bottom have been thoroughly mixed in;  when they have, divide the batter between the two cake pans and bake for thirty minutes, or until a toothpick comes out clean.  Cool the cakes on a baking rack while you prepare the frosting. 

Using a double boiler, melt the unsweetened chocolate over simmering water.  When the chocolate is melted, take it off the water and let it cool.

In the interim, using a stand or electric mixer, beat the butter until pale yellow and creamy--don't overbeat.  Add the powdered sugar and beat on medium speed until it is thoroughly combined, scraping down the sides of the bowl at the end.  Then add the chocolate and vanilla, and beat again until combined.

To assemble the cake, tip the cakes out from the cake pans.  You can leave a slight dome on the layer you designate for the top, but using a serrated knife even off the layer that will be on the bottom.  Then slice each layer in two.

Place the lower half of the bottom layer on the serving plate, then cover with a thin layer of the chocolate frosting.  Repeat with the remaining layers, then frost the sides and then the top of the cake, continuing to use the offset spatula. 

Serves 10 to 12, depending on how thickly you slice it.
