Blackberry Cupcakes with Lemon Glaze — Moist Summer Recipe

Looking for a gentle, natural way to tame your baby’s hair? Sometimes a little mucus ends up doing the job—especially when little ones have a runny nose. While not glamorous, it’s an easy, natural fix: babies often rub their noses and end up smoothing mucus through their hair, and when it dries it can hold a style in place. Of course, I always wash it out afterward, but it makes for a memorable, if slightly gross, morning moment.

My daughter Carly woke up with a sticky hairline recently. I rinsed her hair right away (she protested), but she still looked adorable. Below are a few photos of her all cleaned up after that little incident.

Now for something a lot prettier: these blackberry cupcakes with a silky blackberry-cream cheese frosting. The frosting combines butter, cream cheese, vanilla, and pureed blackberries, which provide a lovely natural purple color. It’s exceptionally smooth thanks to the thorough whipping; I’m already planning a raspberry version next.

I was excited to photograph these with my new camera — they looked beautiful and would be perfect for a bridal shower, wedding, or any special gathering.

Wouldn’t these be gorgeous at a bridal shower or wedding?

Ingredients

For the Cupcakes:

  • 1 3/4 cup all-purpose flour
  • 1 3/4 teaspoon baking powder
  • 1/4 teaspoon baking soda
  • 1/4 teaspoon salt
  • 5 tablespoons butter, softened
  • 1 cup sugar
  • 2 large egg yolks, room temperature
  • 1 teaspoon vanilla
  • 1 cup sour cream or plain yogurt, room temperature
  • 2 large egg whites, room temperature
  • 1/8 teaspoon cream of tartar

For the Frosting:

  • 1/2 cup (1 stick) salted butter, softened
  • 1 1/2 cup powdered sugar
  • 1/8 teaspoon salt
  • 8 ounces (1 stick) cream cheese, softened
  • 6 ounce container blackberries, washed, divided
  • 1/4 teaspoon vanilla

Instructions

For the Cupcakes:

  1. Preheat oven to 350°F and line muffin tins with 18 paper cupcake liners.
  2. In a medium bowl, whisk together flour, baking powder, baking soda, and salt.
  3. In a stand mixer, beat butter and sugar until light and fluffy. Add egg yolks and vanilla.
  4. Alternate adding the sour cream and the dry ingredients in three parts, mixing until combined.
  5. In a separate bowl, beat the egg whites and cream of tartar until stiff peaks form. Gently fold the egg whites into the batter in batches until evenly incorporated.
  6. Spoon about 2 tablespoons of batter into each muffin cup (a cookie scoop works well).
  7. Bake for 15–18 minutes, or until a toothpick inserted into the center comes out clean. Cool completely before frosting.

For the Frosting:

  1. Place about 1/2 cup (roughly 16 berries) blackberries in a small bowl and puree with an immersion blender, food processor, or blender. Press the puree through a mesh strainer to remove seeds; discard the solids.
  2. In a mixer using the whisk attachment (or with a hand mixer), cream the butter, powdered sugar, and salt on low until combined, then increase to medium-high and beat 2–3 minutes until light and fluffy.
  3. Add the cream cheese in small amounts (about 2 ounces at a time), beating and scraping the bowl until smooth. Continue to beat for about 2 more minutes.
  4. Mix in the blackberry puree and vanilla until evenly combined. If needed, adjust consistency with a little powdered sugar or a splash of cream.
  5. Fit a piping bag with a large tip (2D or M1), fill with frosting, and pipe onto each cupcake by starting in the center, working outward, then spiraling up. Top each with a fresh blackberry.

Notes: I use an immersion hand blender to puree the berries. The cupcake is adapted slightly from Joy of Cooking (I used all-purpose flour and salted butter). The frosting is adapted from a Blackberry Frosting recipe and adjusted with salted butter, added vanilla, and slightly less frosting per cupcake.
