I loathe making chiffon/angel food cakes and Swiss rolls so I was not so thrilled when this cake was chosen as the winning cake to be baked by The Cake Slice Bakers. In fact, my friend Maranda from Jolts & Jollies and I both held our breath and hoped this cake wouldn't be the winning cake because it seemed so labor intensive BUT in the end it was so much easier than I ever expected. Despite my reservations, this cake was a complete success and really quite DELICIOUS. It's also really pretty and that's always a plus. There are lots of photos in this post, bear with me.
This is not your ordinary roll up cake. Firstly, you make your own butterscotch sauce (butter, sugar, cream) then you add some of that to freshly whipped cream to make the filling. It then gets spread on the cake and rolled up with sliced almonds scattered throughout. You cut the cake into four pieces and roll it up around itself until you have something that looks like a giant cinnamon roll. And who doesn't like giant cinnamon rolls, especially when the tender cake is the dough and it's filled with salted butterscotch cream?!
I haven't always liked butterscotch. It wasn't until recently that I started to like it. I always assumed that butterscotch was nothing more than those little golden candies my grandpa used to carry around in his pockets. Why didn't anyone tell me it was like a cross between gooey, sticky toffee and caramel? Man, this stuff was good! The recipe below makes 1 1/2 cups of sauce but only one cup is needed for the filling. You can drizzle the remaining sauce over the cake or on ice cream, or in coffee or just stick your finger in it and lick it. oh yum! Make this!
Butterscotch Cream Roll-Up
from Vintage Cakes via Cooking By The Book
1/3 cup unsalted butter
1 cup firmly packed dark brown sugar
1 cup heavy cream
1 tablespoon whisky
1 ½ teaspoons pure vanilla extract
½ teaspoon fine sea salt
1 cup sifted cake flour
1 cup sugar
1 teaspoon baking powder
½ teaspoon fine sea salt
½ cup canola oil
4 egg yolks, at room temperature
¼ cup water
1 teaspoon pure vanilla extract
6 egg whites, at room temperature
¼ teaspoon cream of tartar
1 ½ cups cold heavy cream
½ cup natural sliced almonds, toasted plus more for this outside of the cake, if desired
To make the butterscotch sauce: Melt the butter over medium heat in a large heavy-bottomed sauce pan. Dump in the brown sugar all at once and stir with a wooden spoon to combine. Cook, stirring frequently, until the mixture begins to simmer and changes from a wet sand consistency to a liquid that fives off a lovely molasses smell and looks like taffy, approximately 3 minutes from the time it comes to a simmer. Drizzle ¼ cup of the cream into the mixture and vigorously blend the cram into the sugar and whisk in the remaining cream. Turn the heat up to medium-high and allow the sauce to boil, whisking occasionally, until it has darkened, about 8 minutes. Remove the pot from the heat and allow the sauce to cool for a few minutes before adding the whisky, vanilla, and salt. Refrigerate until cold.
To make the cake: Spray a 12 x 16 inch jelly roll pan with nonstick baking spray (with flour), line it with parchment paper, and then spray the parchment paper with more nonstick baking spray. Center a rack in the center of your oven and preheat the oven to 325⁰F.
Sift together the flour, baking powder, salt, and ¾ cup of the sugar in a large bowl, then whisk the ingredients by hand. In a small bowl, whisk together the oil, yolks, water and vanilla. Add the liquid mixture to the dry ingredients and briskly stir with a rubber spatula until just smooth.
In the clean bowl of stand mixer fitted with the clean whisk attachment, whip the egg whites on medium speed until frothy. Add the cream of tartar and gradually increase the speed to high, whipping until the whites just form a soft peak. With mixer on medium speed, gradually add the remaining ¼ cup of sugar in a slow stream. Return the mixer to high and continue whipping until the whites just begin to hold firm, shiny peaks.
With a rubber spatula, fold a third of the whites into he batter, using as few strokes as possible. Add the remaining whites, folding until incorporated. Pour the batter into the prepared pan and smooth the top with an offset spatula. Place the pan in the oven. Bake the cake until it springs back when lightly touched and is barely golden in color, 16 to 20 minutes. Cool the cake on a wire rack until it reaches room temperature.
To make the filling: Begin by placing the bowl of a stand mixer and its whisk attachment in the freezer for 5 minutes. Fit the cold bowl and whisk to the mixer and whip the 1 ½ cups of cold heavy cream and 1 cup of the cold butterscotch sauce together on low speed until the ingredients are blended. Gradually turn the mixer up to high speed and whip just until the cream holds soft peaks but is not yet stiff.
To assemble the cake: Keep the cake in its pan and orient the pan so the longer side is closed to you. Cut the cake with a serrated knife into four equal pieces measure 4 by 12 inches. Cut through the underlying parchment paper with a pair of scissors in the same places that you cut the cake so you have four quarters of cake [with parchment paper attached] that can each move independently.
Leaving the cake in the pan, spread a bit more than half of the butterscotch cream evenly over the cake and sprinkle with the toasted almonds. Refrigerate the remainder of the cream while you roll up the cake.
Here comes the fun part: rolling the cake! With the pan still oriented with the longer side closest to you, lift up the nearest edge — both cake and paper — of one of your 4 strips. Using the parchment paper as the cake’s support, begin to tuck the cake into a roll and continue tucking [and peeling away the parchment paper] while gently rolling the cake away from you into a roll. Place the rolled cake upright on a serving plate, so the spiral of cake and filling is visible at the top. [Don’t worry, it gets easier from here.]Lift the next cake strip, using the parchment paper to support it, and wrap the strip around the roll on the serving plate, beginning where the outside edge of the first cake left off, in order to create a bigger roll. Continue with the next two strips, beginning the wrap where the last left off, to make one enormous rolled up cake.
Finish by frosting the sides with the reminder of the cream [you might need to give the cream a few turns with a hand whisk to stiffen it up], leaving he top free to show of the spiral of cake and cream. If you desire, you can pat more almonds into the sides of the cake. Refrigerate the cake for at least 1 hour and up to one day, lightly wrapped in plastic. Just before serving, warm the remaining butterscotch sauce and drizzle it over the individual servings.
Well wrapped and refrigerated, this cake keeps up to 3 days.
