White Chocolate Cupcakes with White Chocolate Cream Cheese Frosting
1 3/4 cups unbleached all-purpose flour
1 tsp baking powder
1/2 tsp kosher salt
12 tbsp (1 1/2 sticks) unsalted butter, very soft
1 cup sugar
1 tbsp pure vanilla extract
8 oz white chocolate, chopped
1/2 cup unsweetened coconut milk
5 large egg whites
White Chocolate Cream Cheese Buttercream (I recommend you double the suggested amounts)
6 oz cream cheese (at room temperature)
6 tbsp (3/4 stick) unsalted butter (at room temperature)
1/2 tsp pure vanil extract
1/4 tsp kosher salt
4 1/2 oz white chocolate, chopped
For the cupcakes:
1. Preheat the oven to 350 degrees F. Line a standard 12-cup muffin tin with paper liners, and line 2 more cups in a second muffin tin.
2. In a medium bowl, sift together the flour, baking powder, and salt; set it aside.
3. In the bowl of an electric mixer fitted with the paddle attachment, beat together the butter, sugar, and vanilla on medium-high speed until light and smooth, about 3 minutes.
4. Bring about 2 inches of water to a simmer in a large saucepan. Place the white chocolate in a heatproof bowl, set it over the simmering water, and stir until it has melted. Add the warm, melted chocolate to the butter mixture and stir to combine. Scrap down the sides of the bowl with a rubber spatula.
5. With the mixer on low speed, alternate adding the flour mixture and the coconut milk, adding one third of each at a time and letting them fully mix in before adding the next. Transfer the batter to a medium mixing bowl.
6. Clean and dry the bowl of the electric mixer well. You want to make sure the bowl is absolutely dry to whip your whites. Add the egg whites, and using the whisk attachment on medium speed, beat to soft peaks, about 4 minutes. In three additions, fold the whites into the batter. Note that folding, is not mixing. To fold properly, drop 1/3 of the whites into the batter, gently lift the batter from the bottom and fold over the whites. Go around the bowl repeating. Add another 1/3 of the white and repeat the folding; and then finish folding in the remaining egg whites. Be careful not to over-mix. Folding takes a little bit to master.
7. Fill the muffin cups about three-quarters full with batter. Bake, rotating the tins halfway through, until the cupcakes spring back to the touch and a cake tester inserted in the center of a cupcake comes out clean, 15 to 20 minutes. Transfer the tin to a wire rack. Invert the cupcakes onto the rack, turn them top side up and let them cool completely.
[Note: my cupcakes sank a tiny bit, I'll play with the recipe again to see if it's something recurrent. It's possibly the egg whites sinking in a bit.]
1. In the bowl of an electric mixer fitted with the paddle attachment, beat together the cream cheese, butter, vanilla, and salt on medium-high speed until light and smooth, about 3 minutes.
2. Bring about 2 inches of water to simmer in a saucepan. Place the chocolate in a heatproof bowl, place the bowl over the pan, and stir until the chocolate is melted. Slowly add the melted chocolate to to the cream cheese mixture and beat to combine, scraping down the sides of the bowl as necessary. If the butter-cream is too soft to spread, cover the bowl and chill it for 20 minutes; then white it in the mixer for 30 seconds before using. (The butter-cream can be refrigerated for 1 week or frozen for up to 1 month. Before using, bring it to room temperature and beat it for a few minutes until smooth.)
3. Spread the tops of the cupcakes with the frosting, swirling it decoratively.
The cupcakes can be kept in an airtight container in the refrigerator for up to 3 days.
A FEW NOTES:
Salt in recipes from this book:
In November 12, 2009 article in the NYTimes T magazine ran an article on Karen DeMasco’s book and in it, they specified white type of kosher salt Karen uses. I didn’t think much on it, until I read that Morton’s weighs differently than Diamond Crystal, which affects baking, as it’s pretty precise. I’ve kept the excerpt below for you as well.
One thing to note: DeMasco’s recipes call for kosher salt, but she doesn’t mention which brand she uses, Diamond Crystal or Morton. (Though they look similar, the brands vary quite a bit by weight.) She said in an e-mail message that she uses Diamond Crystal kosher salt exclusively. When using this book, either use Diamond Crystal kosher salt or adjust the quantity accordingly: 1/2 teaspoon of Diamond Crystal kosher salt = 3/8 teaspoon of Morton kosher salt = 1/4 teaspoon of fine sea or iodized salt.
Melting white chocolate:
Because white chocolate has a very low melting point, around 111 degrees F, it’s tough to control melting in a microwave, a method that works for dark and/or milk chocolate. You really should melt white chocolate in a double boiler carefully over low heat, and once melted, use immediately as the chocolate dries out easily.
I recommend making twice the amount of frosting if you want to create lovely, generous dollops and not “ration” your frosting.
