Strawberry Milk Bar Cake
A momofuku-style layer cake with fine-crumbed vanilla buttermilk layers, a salty milk crumb and strawberry buttercream.
Servings: 1 triple layer 6-inch cake
Ingredients
For the vanilla buttermilk cake:
- 2 cups cake flour
- 1 1/3 cups superfine or regular sugar
- 2 3/4 teaspoons baking powder
- 1/2 teaspoon kosher salt
- 9 tablespoons cold unsalted butter cut into pieces
- 1 1/2 tablespoons oil I use olive or vegetable
- 2/3 cup milk room temperature (I use almond milk but any kind will work), mixed with 2 teaspoons apple cider vinegar (this will be divided in two parts).
- 3 large eggs room temperature
- 1.5 teaspoons vanilla extract
For the milk crumb
- 1/2 cup instant nonfat dry milk such as Carnation
- 1 ⁄4 cup all-purpose flour
- 2 tablespoons cornstarch
- 2 tablespoons sugar
- 1 ⁄2 teaspoon kosher salt
- 4 tablespoons unsalted butter melted
- 1-2 tablespoons milk optional
For the frosting:
- 1 stick of butter room temperature
- 2.5 cups powdered sugar
- ½ teaspoon vanilla
- pinch of salt
- scant 1 cup fresh or frozen strawberries chopped (if using frozen strawberries, thaw and drain liquid before using).
Instructions
For the vanilla buttermilk cake:
- Preheat oven to 350 degrees and grease a 9x13 baking pan.
- Sift together the flour, sugar, baking powder and salt. Using an electric beater, add in the butter in small pieces, about 10 seconds apart. Beat until the butter is incorporated in small crumbs, then add the oil and continue to beat until there are no clumps and you have a fine, crumbly, cornmeal-like texture.
- Add 1/2 CUP of the milk to the mixture and beat for 4 minutes (beating for this long will help create a more even consistency that will bake into a more even cake). Beat the eggs and vanilla into the remaining milk mixture and gradually add the egg mixture to the rest of the ingredients. Increase speed to medium and beat for one minute, then scrape down the sides and fold batter a few times to make sure everything is incorporated.
- Pour batter into prepared pan and bake for 35-40 minutes, or until edges are golden and an inserted toothpick comes out clean. Let cool before cutting.
For the milk crumb:
- Reduce oven temperature to 325 degrees.
- Whisk the dry milk, flour, cornstarch, sugar and salt together. Stir in the melted butter until you get small clumps. If there are too many dry crumbs remaining, add an additional 1-2 tablespoons of milk until you get a mixture with a few pea-sized clumps and some smaller crumbs. Pour onto a parchment-lined baking sheet and bake for 15 minutes, or until golden brown, stirring once or twice.
For the frosting:
- Beat the butter and sugar together until smooth. Add the vanilla and salt. Fold in the strawberries.
To assemble:
- Use the bottom of a six-inch springform pan as a guide to cut out two 6-inch round circles from the 9x13 pan of cake. Remove layers, set aside, and level as necessary.
- Re-assemble the springform pan and line it with plastic wrap. Use the remaining scraps from the 9x13 cake to form an even layer of cake in the bottom of the pan--make this layer the same thickness as the whole layers you just cut out (you will have more than enough scraps, so eat the rest).
- Spread 1/3 of the frosting over the scrap cake base. Sprinkle with 1/3 of the milk crumbs. Add one of the whole layers on top. Repeat with 1/3 of the frosting and 1/3 of the crumbs. Add the last layer of cake and repeat with 1/3 of the frosting and 1/3 of the crumbs.
- I like to freeze the cake, uncovered, until everything has set, then cover the top with foil. Allow to freeze at least 2-3 hours but preferably overnight to help everything set. Thaw for 2-3 hours in the fridge or 1-2 hours at room temperature before serving.
