Daring Bakers: Ice Cream Petit Fours

"The August 2010 Daring Bakers’ challenge was hosted by Elissa of 17 and Baking. For the first time, The Daring Bakers partnered with Sugar High Fridays for a co-event and Elissa was the gracious hostess of both. Using the theme of beurre noisette, or browned butter, Elissa chose to challenge Daring Bakers to make a pound cake to be used in either a Baked Alaska or in Ice Cream Petit Fours. The sources for Elissa’s challenge were Gourmet magazine and David Lebovitz’s “The Perfect Scoop”."

I was really excited to try making ice cream again, since my last attempt was a little bit of a failure. I was also really excited to try making pound cake, since I'd never made it before!
I'm happy to report that the ice cream was a huge success! It was super creamy and had a great vanilla flavour! And it stayed frozen like ice cream is supposed to! :)

Unfortunately the pound cake was a COMPLETE FAILURE! :( When I took it out of the oven and stuck a toothpick in it it seemed to be done (and I had left it in for the recommended amount of time). But as the cake cooled I quickly realized that the middle was still uncooked! I really didn't have the time to start from scratch again so I quickly put it back in the oven and hoped for the best. But of course the cake came out WAY TOO DRY! :( I was really disappointed. But I continued on like a trooper and finished the Petit Fours anyway!
I tried one of the finished Petit Fours and the cake was terrible! So I decided to salvage the ice cream and throw away the cake.

The cake looked very sad sitting there in an abandoned pile. But I have to admit...the little ice cream blocks are pretty darn cute! :) So it was all worth it in the end.

I tried the one that I cut open for the photo here and the cake was actually not bad! I guess some parts of the cake were not too dry...
My ice cream layer was thicker than it should have been, so it kind of bulged out of the sides and made the Petit Fours look like leaning towers...but it still tasted good! I loved the chocolate on the outside, though next time I would like the chocolate to be a little thinner.

Note:
The pound cake calls for cake flour. You can make 1 cup of cake flour by placing 2 tablespoons of corn starch in a 1 cup measure, and filling to the top with all purpose flour.

Vanilla Ice Cream

Ingredients:
1 cup (250ml) whole milk
A pinch of salt
3/4 cup (165g) sugar
1 vanilla bean, split lengthwise OR 2 teaspoons (10ml) pure vanilla extract
2 cups (500ml) heavy (approx 35% butterfat) cream
5 large egg yolks
1 teaspoon (5ml) pure vanilla extract

Directions:
1. Heat the milk, salt, and sugar in a medium saucepan until the liquid steams. Scrape out the seeds of the vanilla bean with a paring knife and add to the milk, along with the bean pod. Cover, remove from heat, and let infuse for an hour. (If you do not have a vanilla bean, simply heat the milk, salt, and sugar in a medium saucepan until the liquid steams, then let cool to room temperature.)
2. Set up an ice bath by placing a 2-quart (2 litre) bowl inside a large bowl partially filled with water and ice. Put a strainer on top of the smaller bowl and pour in the cream.
3. In another bowl, lightly beat the egg yolks together. Reheat the milk in the medium saucepan until warmed, and then gradually pour ¼ cup warmed milk into the yolks, constantly whisking to keep the eggs from scrambling. Once the yolks are warmed, scrape the yolk and milk mixture back into the saucepan of warmed milk and cook over low heat. Stir constantly and scrape the bottom with a spatula until the mixture thickens into a custard which thinly coats the back of the spatula.
4. Strain the custard into the heavy cream and stir the mixture until cooled. Add the vanilla extract (1 teaspoon [5ml] if you are using a vanilla bean; 3 teaspoons [15ml] if you are not using a vanilla bean) and refrigerate until thoroughly chilled, preferably overnight.
5. Remove the vanilla bean and freeze in an ice cream maker. If you don’t have an ice cream maker, you can make it without a machine. See instructions from David Lebovitz: http://www.davidlebovitz.com/archives/2007/07/making_ice_crea_1.html

Brown Butter Pound Cake

Ingredients:
19 tablespoons (9.5 oz) (275g) unsalted (sweet) butter
2 cups (200g) sifted cake flour (not self-rising; sift before measuring) (See “Note” section for cake flour substitution)
1 teaspoon (5g) baking powder
1/2 teaspoon (3g) salt
1/2 cup (110g) packed light brown sugar
1/3 (75g) cup granulated sugar
4 large eggs
1/2 teaspoon pure vanilla extract

Directions: 
1. Preheat the oven to 325°F/160°C and put a rack in the center. Butter and flour a 9”x9” (23cmx23cm) square pan.
2. Place the butter in a 10” (25cm) skillet over medium heat. Brown the butter until the milk solids are a dark chocolate brown and the butter smells nutty. (Don’t take your eyes off the butter in case it burns.) Pour into a shallow bowl and chill in the freezer until just congealed, 15-30 minutes.
3. Whisk together cake flour, baking powder, and salt.
4. Beat the brown butter, light brown sugar, and granulated sugar in an electric mixer until light and fluffy, about 2 minutes. Beat in the eggs one at a time, mixing well, and then the vanilla extract.
5. Stir in the flour mixture at low speed until just combined.
6. Scrape the batter into the greased and floured 9”x9” (23cmx23cm) square pan. Smooth the top with a rubber spatula and rap the pan on the counter. Bake until golden brown on top and when a toothpick inserted into the center comes out clean, about 25 minutes.
7. Cool in the pan 10 minutes. Run a knife along the edge and invert right-side-up onto a cooling rack to cool completely.

Chocolate Glaze

Ingredients:
9 ounces (250g) dark chocolate, finely chopped
1 cup (250 ml) heavy (approx 35% butterfat) cream
1 1/2 tablespoons (32g) light corn syrup, Golden syrup, or agave nectar
2 teaspoons (10ml) vanilla extract

Directions:  
Stir the heavy cream and light corn syrup in a small saucepan over medium heat until it comes to a boil. Remove from heat and add the dark chocolate. Let sit 30 seconds, then stir to completely melt the chocolate. Stir in the vanilla and let cool until tepid before glazing the petit fours.

Assembly Instructions 

1. Line a 9”x9” (23cmx23cm) pan with plastic wrap, so that no sides of the pan are exposed and so there is some extra plastic wrap hanging off the sides. Spread 1 ¾ to 2 cups (450ml to 500ml) ice cream into the pan. Cover with more plastic wrap and freeze several hours.
2. Once the brown butter pound cake has completely cooled, level the top with a cake leveler or a serrated knife. Then split the cake in half horizontally to form two thin layers.
3. Unwrap the frozen ice cream. Flip out onto one of the layers of cake and top with the second layer of cake. Wrap well in plastic wrap and return to the freezer overnight.
4. Make the chocolate glaze (see above.)
5. While the glaze cools, trim ¾” (2cm) off each side of the ice cream cake to leave a perfectly square 7.5” (19cm) ice cream cake. Cut the cake into twenty five petit fours, each 1.5”x1.5” (4cmx4cm).
6. Glaze the petit fours one at a time: place a petit four on a fork and spoon chocolate glaze over it.
7. Place the petit fours on a parchment-lined baking sheet and return to the freezer for one hour.
