peach cupcakes with brown sugar frosting

My friend Molly — she of the dry-rubbed ribs and apple tarte tatin fame — is leaving us for the kind of love that requires one to take up residence in another state. We’re all mighty bummed out about this and not making it easy on her, not only pouting over her imminent departure at every turn but insisting that she perform her half-day rib magic one last time at her going-away party this weekend.

Because it was Molly who introduced me to the unparalleled awesomeness that is South Carolina peaches (albeit from the mountains of North Carolina) [and how they’re even better when they’re sliced and dolloped with whole milk yogurt, or about the only breakfast (with less-exciting and much-fuzzier local peaches) I can fathom on these steaming August days], I wanted to bake something with peaches for the party, but not peach hand pies or peach crème fraîche pie. I wanted to make peach cupcakes.

Alas, I should have known better to even casually mention to a friend a couple weeks ago that I’ve had a lot of recipe mojo lately, landing on things haven’t require a second run to get them right because you can now guess exactly what happened with my first round of these cupcakes, the ones I forced upon my friends: they needed some work. Worried about the peaches sinking, I chopped them so eensy, you couldn’t detect them and the cake was too dry and way too sweet. Yesterday’s batch was much more successful — lighter and fluffy, more moist and with juicy bites of peach throughout. The brown sugar cream cheese frosting was also a bit of an experiment; I’ve seen versions of it before but they often only have tiny amounts of brown sugar in them. I wanted the brown sugar to be prominent and, lo, it was. The only trickiness is that due to the moisture content of brown sugar, the frosting never gets as firm as traditional cream cheese frostings will, but that doesn’t mean that I’ll be going back to traditional ones any time soon — you cannot turn back after trying this one.

Peach Cupcakes with Brown Sugar Cream Cheese Frosting

These cakes are extremely light, airy and moist, nothing like the dense cake recipes more traditionally used as cupcake bases. Personally, I consider this a very good thing. You know what else? Sans frosting, they’d make great breakfast muffins — just dial back one of the sugars by a generous quarter-cup and maybe even swap half of that flour with whole wheat. You could also chop in some pecans, but don’t blame me if nobody in your house wants to share.

Makes 24 to 28 cupcakes

3 cups cake flour
1 1/2 teaspoons baking powder
1 1/2 teaspoons baking soda
1 teaspoon salt
Pinch of nutmeg
3/4 cup (1 1/2 sticks or 6 ounces) unsalted butter, at room temperature
3/4 cup granulated sugar
3/4 cup dark or light brown sugar, packed
2 large eggs, lightly beaten
1 teaspoon vanilla extract
1 1/2 cups (12 ounces) buttermilk, sour cream or full-fat yogurt
3 large peaches, peeled, cored, and chopped smallish (I went for a 1/3-inch dice)

Preheat the oven to 350°F. Line 28 muffin cups with paper liners.

Sift together the flour, baking powder, baking soda, salt and nutmeg and set aside. Cream the butter and sugars together, beating until fluffy. Add the eggs, one at a time, scraping down the sides and bottom of the bowl between each addition, and then the vanilla. Gently mix in the buttermilk, sour cream or yogurt. Stir in the dry ingredients and fold in the peach chunks.

Divide the batter evenly among the prepared cupcake liners. Bake for 18 to 22 minutes, or until a tester inserted into the center of cupcakes comes out clean. Cool the cupcakes for five minutes in the tin, then turn them out onto a wire rack to cool completely.

Brown Sugar Cream Cheese Frosting

Cornstarch? Let me explain: Quick buttercreams and cream cheese frostings are generally made by whipping fatty ingredients (butter, cream cheese, yes please) with powdered sugar. Powdered sugar works in a way that granulated sugar does not because it is mixed with cornstarch, which both keeps the sugar from clumping in its packaging and thickens the frosting. Brown sugar is not only more damp than granulated and powdered sugar, it’s missing that cornstarch thickener, so I added some to help the frosting set up. It’s still a bit thinner than traditional cream cheese frosting but the flavor leaves the stuff you’re used to in the dust. And for me, that’s all that matters.

1 1/4 cups light brown sugar
1/4 cup cornstarch
1/2 cup powdered sugar
2 8-ounce packages of cream cheese, at room temperature
1/2 cup (4 ounces or 8 tablespoons) unsalted butter, at room temperature
1/2 teaspoon vanilla extract

In a small bowl, whisk together the brown sugar, cornstarch and powdered sugar. In a large bowl, beat the cream cheese and butter until fluffy. Add the sugar-cornstarch mixture and vanilla, beat until frosting is smooth and light. Chill the bowl in the refrigerator until it thickens back up a bit, about 30 minutes, then spread or dollop on cooled cupcakes.

Tip: Did you know you can make your own brown sugar?

Some notes, or questions I am going to anticipate and try to answer before they are asked: I bought the brown cupcake liners at the New York Cake & Baking Supply on 22nd Street (and wow, do I miss only living a few blocks from there) but they’re also available on Amazon and from many other online baking supply shops. I piped dollops of the frosting with a Wilton #10 round tip. I have a small, inexpensive kit like this (but a different version) that pretty much works for anything I need to do. It’s a great investment for those of us that just like to dabble in decorating at home.
