Ingredients
  

  • All-purpose flour – For structure and a soft crumb.
  • Granulated sugar – Sweetness and moisture.
  • Baking powder – Reliable lift.
  • Fine salt – Balances sweetness.
  • Unsalted butter (room temperature) – Flavor and tenderness.
  • Neutral oil (canola or vegetable) – Extra moisture.
  • Eggs (room temperature) – Structure and richness.
  • Whole milk (room temperature) – Smooth batter and even baking.
  • Sour cream or plain Greek yogurt – Soft, moist crumb.
  • Pure vanilla extract – Warm, classic flavor.
  • Almond extract (optional) – Bakery-style note.
  • Rainbow jimmies (sprinkles) – Use the long, rod-shaped kind to prevent bleeding.
  • For the frosting: Unsalted butter (soft), powdered sugar, vanilla extract, a pinch of salt, and a splash of milk or heavy cream.
  • Extra sprinkles – For topping.

Instructions
 

  • Prep the pans: Heat oven to 350°F (175°C). Line 12–14 muffin cups with paper liners. For taller domes, fill only 12 and bake a touch longer.
  • Mix dry ingredients: In a medium bowl, whisk 1½ cups all-purpose flour, 1½ teaspoons baking powder, and ½ teaspoon fine salt. Set aside.
  • Cream the fats: In a large bowl, beat ½ cup unsalted butter with ¼ cup neutral oil and 1 cup granulated sugar until light and fluffy, about 2–3 minutes.
  • Add eggs and flavor: Beat in 2 large eggs, one at a time. Mix in 2 teaspoons vanilla extract and ¼ teaspoon almond extract (optional) until smooth.
  • Combine wet and dry: Stir ½ cup sour cream into ½ cup whole milk. Add the dry ingredients to the butter mixture in two additions, alternating with the milk mixture. Mix on low just until combined. Do not overmix.
  • Fold in sprinkles: Gently fold ½ cup rainbow jimmies into the batter with a spatula. Stop as soon as they’re evenly distributed.
  • Fill and bake: Divide batter among liners, filling about ⅔ to ¾ full. Bake 18–22 minutes, until the tops spring back and a toothpick comes out with a few moist crumbs.
  • Cool completely: Let cupcakes cool in the pan 5 minutes, then transfer to a rack to cool fully before frosting.
  • Make the frosting: Beat 1 cup (2 sticks) unsalted butter until creamy. Add 3–3½ cups powdered sugar, 1 teaspoon vanilla, a pinch of salt, and 2–3 tablespoons milk or cream. Whip until smooth and fluffy, 2–3 minutes. Adjust milk for consistency.
  • Decorate: Pipe or spread frosting on cooled cupcakes. Finish with extra rainbow sprinkles. Serve and celebrate.
