The Lee Bros. Charleston Kitchen. And they don't mean tears of joy. It's the toffee-sweet icing that's the trouble.
"It has to be just the right temperature," they explain. "Warm enough to be pourable, but cool enough that, when you work it around the cake with an icing spatula, it sets in place." When the icing sets, magic happens; it develops a toothsome, fudge-like crystalline texture. It's also where things can go wrong. If the icing sets too fast, you'll rip apart your cake layers as you attempt to spread it. If it doesn't cool fast enough, you'll have caramel icing running all over the counters. Freaked out yet? Don't be.
It's likely the reputation of a purportedly untameable caramel icing that's kept this cake a Southern confection, rather than a coast-to-coast classic. But when Matt and Ted hand over crystal clear directions, a failsafe recipe, and a few tricks of the trade, bakers from Maine to Arizona will be crowning their cake stands with this beauty.
- Catch the run-off. Line a sheet pan with waxed paper. Set a rack on top and ice the layers here. The wax paper will catch any run-off from too warm icing. Return the overflow to the icing bowl so it can cool further.
- Put the kettle on. Have a small amount of hot water an an electric hand-mixer nearby as you ice the cake so that, if the icing seems to be cooling too readily and seizing up, you can quickly soften it by adding a teaspoon of hot water to the bowl and blending it to loosen it up.
- Get the hairdryer from the bathroom. Icing seized on the cake before you've had a chance to spread it? Blast it with the hairdryer to spot-heat cooled icing.

from The Lee Bros. Charleston Kitchen
time: 2 hours
1 cup (2 sticks) unsalted butter, softened, plus more for the pans
2 ½ cups sifted all-purpose flour, plus more for the pans
2 teaspoons baking powder
2 teaspoons salt
¼ teaspoon baking soda
2 cups sugar
3 large eggs
2 large egg yolks
2 teaspoons pure vanilla extract
¾ cup whole milk
1 ½ cups whole milk
4 cups sugar
10 tablespoons (1 ¼ sticks) butter
2 teaspoons kosher salt, plus more to taste
¼ teaspoon baking soda
1 tablespoon pure vanilla extract
1. Make the cake: Preheat the oven to 350°F. Grease and flour two round 9 by 2-inch cake pans. Pour about a tablespoon of flour into each of the pans and roll it around, tapping as you go, until the sides and bottom are covered completely with a thin layer of flour. Tip the pans, and tap out excess flour.
2. In a large mixing bowl, mix thoroughly with a whisk the flour, baking powder, salt, and baking soda.
3. In a separate large bowl, beat the butter with an electric mixer until creamy, about 30 seconds. Add the sugar in 1/2-cup measures, beating about 15 seconds after each addition and scraping down the sides of the bowl if necessary, until the mixture has lightened in color and become fluffy, about 2 minutes. Add the eggs and egg yolks, one at a time, and the vanilla, beating for 15 seconds after each addition.
4. Add the flour mixture to the butter mixture in thirds, alternating with additions of the milk. To avoid overmixing the batter, mix gently with a wooden spoon or rubber spatula after each addition, until the ingredient is just incorporated. Beat until all the ingredients have been incorporated, and then just a few strokes beyond. Divide the batter between the cake pans and spread the tops evenly.
5. Bake until a cake tester or toothpick emerges clean, about 30 minutes. Remove from the oven and let the cakes cool in their pans on a rack for 10 minutes, then slide a thin paring knife around the edge of the pans, and invert the cakes. Turn each cake again so its rounded top is facing up, and cool the cakes completely on the rack.
6. Make the icing: Pour the milk and 3 cups of the sugar into a large, deep, heavy-bottomed pot over medium-high heat, mixing with a whisk. Add the butter and the salt, whisking occasionally until the butter melts. When mixture just simmers, cut the heat, but keep over the warm burner.
7. Pour the remaining 1 cup sugar into a saucepan. Cook the sugar over medium-high heat until it becomes a syrup, stirring every so often with a wooden spoon as it begins to brown, until the sugar syrup is evenly amber colored, 5 to 8 minutes. Pour the syrup into the warm milk mixture, being very careful, as the caramel will bubble and sputter when it hits the hot milk. Turn the heat beneath the pot to high and, whisking gently until all the syrup has completely dissolved into the roiling milk mixture, continue to cook to the soft-ball stage, about 238°F; this may take 8 to 12 minutes.
8. Cut the heat beneath the caramel and gently whisk in the vanilla and the baking soda. Dip a spoon into the caramel, and let it cool to taste it. Season the caramel to taste with salt, and pour it into the bowl of a standing mixer (or use an electric hand-mixer and a large bowl). Beat on low speed as it cools, 15 to 20 minutes depending on the temperature of your kitchen, until the icing is creamy and thick (between 100°F and 105°F). Remove the bowl from the mixer stand and let cool 5 to 10 minutes more, until the icing is between 95°F and 98°F—it should fall off your spatula in a ribbon that remains discernible on the surface of the icing for 10 seconds.
9. Set the first cake layer on a rack set over a sheet plan lined with waxed paper. Have an electric hand-mixer and the hot water nearby to blend a teaspoon or two into the icing if it becomes too thick to spread. Pour enough of the icing over the cake to cover the top in a layer about ¼ inch thick (if it drips over the edge in places, that’s fine; this is an early test of whether it’s going to set in place or not). Top the first cake with the second cake layer and pour the rest of the icing in stages over the top of the cake, letting it run down the sides and using an icing spatula to guide the icing around the cake as it drips, until the entire cake is covered, for a traditional, classic look. (If you prefer the dramatic look of cake layers peeking out from behind a curtain of icing drips, by all means choose that route!) If you need to reuse any icing that overflows into the pan, simply move the cake on its rack temporarily, scrape up the icing from the waxed paper with a spatula and return it to the bowl, replace the rack over the pan, and continue to ice the cake.
10. Once the icing has set, using two spatulas carefully transfer the cake from the rack to a cake stand and let stand at room temperature beneath a cake dome until ready to serve. Only refrigerate if you plan to store the cake for more than 2 days.
