Golden Yellow Cupcakes with Milk Chocolate Frosting - Sweet and Savory Kitchens

Margaux says…

It’s cake season around here…we have several birthdays in January and February in our family, so I’m basically making cake after cake for about two months. This is one of my favorite cake recipes…I typically make it as a 9″ layer cake, but my sister-in-law wanted cupcakes for her birthday party, and they turned out really great.  I’ve posted about the frosting before, on a similar cake that I’ve made often, and also love, but since I discovered this Cook’s Illustrated version I may just make this one from now on whenever I’m wanting a yellow cake.  Because of science-y Cook’s Illustrated details, this cake is fluffier and has a finer crumb.  And the frosting is silky and delicious…you have to try it!

Fluffy Yellow Cupcakes with Milk Chocolate Frosting

from Cook’s Illustrated

2 1/2 cups cake flour

1 1/4 teaspoons baking powder

1/4 teaspoon baking soda

3/4 teaspoon table salt

1 3/4 cups sugar (12 1/4 ounces)

10 tablespoons unsalted butter, melted and cooled slightly

1 cup buttermilk, room temperature

3 tablespoons vegetable oil

2 teaspoons vanilla extract

6 large egg yolks, room temperature

3 large egg whites, room temperature

1. Adjust oven rack to middle and heat to 350 degrees.  Place 27 cupcake liners into cupcake tins (or grease two 9″ round cake pans and line with parchment paper, then grease and flour).  Whisk flour, baking powder, baking soda, salt and 1 1/2 cup sugar in a large bowl.  In 4 cup liquid measuring cup or medium bowl, whisk together melted butter, buttermilk, oil, vanilla and yolks.

2.  In clean bowl of a stand mixer fitted with a whisk attachment, beat egg whites at medium-high speed until foamy, about 30 seconds.  With machine running, gradually add remaining 1/4 cup sugar, continue to beat until stiff peaks form, about a minute or so.  Transfer to another bowl and set aside.

3.  Add flour mixture to now-empty mixing bowl fitted with a whisk attachment.  With mixer running at low speed, gradually pour in butter mixture and mix until almost incorporated (a few streaks of dry flour will remain), about 15 seconds.  Stop mixer and scrape whisk and sides of bowl.  Return mixer to med-low speed and beat until smooth and fully incorporated, 10-15 seconds.

4.  Using a rubber spatula, stir 1/3 of the whites into the batter to lighten, then add remaining whites and gently fold into batter until no white streaks remain.  Fill each cupcake liner evenly, about 3/4 full.

5.  Bake until toothpick comes out clean, about 17-19 minutes.  Let cool on rack in pans for 10 minutes, then remove from pans and cool completely.  Frost with milk chocolate frosting.

Milk Chocolate Frosting

While cakes are cooling, prepare frosting.

20 tbsp butter, softened

1 cup powdered sugar

3/4 cup dutch processed cocoa powder

pinch table salt

3/4 cup light corn syrup

1 tsp vanilla

8 oz. high quality milk chocolate, like Ghiradelli, melted and cooled slightly

In a food processor, process butter, sugar, cocoa, and salt until smooth, scraping the sides of the bowl as needed, about 30 seconds.  Add corn syrup and vanilla and process until just combined, 5-10 seconds.  Scrape sides of the bowl, then add chocolate and pulse until smooth and creamy, about 10-15 times.

Fill a pastry bag with frosting and either cut the tip off so that there’s about a 1/2″ round opening, or fit with a piping tip.  Swirl frosting generously on cupcakes.  Eat and be happy!

 

Lemon Layer Cake

May 15, 2010

A few weeks ago, we hosted my mom’s retirement party, which of course is a reason to make a cake! I’ve been wanting to make this cake for years, but haven’t due to the numerous steps and seemingly complicated instructions. But I knew my mom was going to come up a day early for the party, which would mean I had someone to watch the little munchkin while I baked! And its spring, which is the perfect time for a lemon cake.

This cake was particularly appealing to me because of the lemon curd and the 7 minute frosting. My grandma Major used to make cakes with 7 minute frosting, and they were always so lovely. Yet the icing was always kind of sickingly-sweet, and wasn’t so lovely the next day. The article that went with this recipe advertised an icing not like the old-fashioned version, and my curiosity was piqued. I wanted the cake to be pretty like my grandma’s, but taste better. This definitely was the best 7 minute frosting I’ve ever had…it was sweet, light, and slightly lemony. It stayed beautiful for DAYS afterwords. And it was a perfect balance with the tart lemon curd filling. The cake was really delicious as well, and I think I’ll use this cake recipe again for vanilla cake lovers, and frost with a plain vanilla buttercream.

I made this cake the day before, and refrigerated it over night. If possible, I will make it the same day I served it when I make this cake again. The frosting and lemon curd were still perfect, but I’m not a huge fan of refrigerated cake…it wasn’t as light and fluffy as it was when I put the cake together.

Oh, and it wasn’t as complicated as it looked. 🙂

Lemon Layer Cake
(from Cook’s Illustrated, March 2007)

Lemon Curd Filling
1 cup fresh lemon juice from about 6 lemons
1 teaspoon gelatin (powdered)
1 1/2 cups granulated sugar (10 1/2 ounces)
1/8 teaspoon table salt
4 large eggs
6 large egg yolks (reserve egg whites for cake)
8 tablespoons unsalted butter (1 stick), cut into 1/2-inch cubes and frozen

Cake
2 1/4 cups cake flour (9 ounces), plus extra for pans
1 cup whole milk , room temperature
6 large egg whites , room temperature
2 teaspoons vanilla extract
1 3/4 cups granulated sugar (12 1/4 ounces)
4 teaspoons baking powder
1 teaspoon table salt
12 tablespoons unsalted butter (1 1/2 sticks), cut into 12 pieces, softened but still cool

Fluffy White Icing
2 large egg whites
1 cup granulated sugar (7 ounces)
1/4 cup water
1 tablespoon fresh lemon juice (from 1 lemon)
1 tablespoon corn syrup

Instructions
1. FOR THE FILLING: Measure 1 tablespoon lemon juice into small bowl; sprinkle gelatin over top. Heat remaining lemon juice, sugar, and salt in medium nonreactive saucepan over medium-high heat, stirring occasionally, until sugar dissolves and mixture is hot but not boiling. Whisk eggs and yolks in large nonreactive bowl. Whisking constantly, slowly pour hot lemon-sugar mixture into eggs, then return mixture to saucepan. Cook over medium-low heat, stirring constantly with heatproof spatula, until mixture registers 170 degrees on instant-read thermometer and is thick enough to leave trail when spatula is scraped along pan bottom, 4 to 6 minutes. Immediately remove pan from heat and stir in gelatin mixture until dissolved. Stir in frozen butter until incorporated. Pour filling through fine-mesh strainer into nonreactive bowl (you should have 3 cups). Cover surface directly with plastic wrap; refrigerate until firm enough to spread, at least 4 hours.

2. FOR THE CAKE: Adjust oven rack to middle position and heat oven to 350 degrees. Grease and flour two 9-inch-wide by 2-inch-high round cake pans and line with parchment paper. In 2-cup liquid measure or medium bowl, whisk together milk, egg whites, and vanilla.

3. In bowl of standing mixer fitted with paddle attachment, mix flour, sugar, baking powder, and salt at low speed. With mixer running at low speed, add butter one piece at a time; continue beating until mixture resembles moist crumbs with no visible butter chunks. Add all but 1/2 cup milk mixture to crumbs and beat at medium speed until mixture is pale and fluffy, about 1 1/2 minutes. With mixer running at low speed, add remaining 1/2 cup milk mixture; increase speed to medium and beat 30 seconds more. Stop mixer and scrape sides of bowl. Return mixer to medium speed and beat 20 seconds longer. Divide batter evenly between cake pans; using rubber spatula, spread batter to pan walls and smooth tops.

4. Bake until toothpick inserted in center of cakes comes out clean, 23 to 25 minutes. Loosen cakes from sides of pans with small knife, cool in pan 10 minutes, then invert onto greased wire rack; peel off parchment. Invert cakes again; cool completely on rack, about 1 1/2 hours.

5. TO ASSEMBLE: Following illustrations below, use serrated knife to cut each cake into 2 even layers. Place bottom layer of 1 cake on cardboard round or cake plate. Using icing spatula, spread 1 cup lemon filling evenly on cake, leaving 1/2-inch border around edge; using cardboard round, gently replace top layer. Spread 1 cup filling on top. Using cardboard round, gently slide bottom half of second cake into place. Spread remaining cup filling on top. Using cardboard round, place top layer of second cake. Smooth out any filling that has leaked from sides of cake; cover with plastic wrap and refrigerate while making icing.



6. FOR THE ICING: Combine all ingredients in bowl of standing mixer or large heatproof bowl and set over medium saucepan filled with 1 inch of barely simmering water (do not let bowl touch water). Cook, stirring constantly, until mixture registers 160 degrees on instant-read thermometer, 5 to 10 minutes. Remove bowl from heat and transfer mixture to standing mixer fitted with whisk attachment. Beat on medium speed until soft peaks form, about 5 minutes. Increase speed to medium-high and continue to beat until mixture has cooled to room temperature and stiff peaks form, 5 minutes longer. Using icing spatula, spread frosting on cake. Serve. (Cake can be refrigerated for up to 1 day before serving.)





The filling can be made a day ahead and refrigerated, but it will become quite stiff; fold it with a rubber spatula to loosen it before spreading onto the cake. For neater slices, dip a knife into hot water before cutting the cake. Leftovers can be stored covered in the refrigerator, with the cut side of the cake covered tightly with plastic wrap, for up to 3 days.
