These are some of the most popular cupcakes I’ve ever baked. Seriously, people raved not just about the flavor (which can transport you back to your childhood summers in one bite) but the texture as well. I say a good recipe goes a very long way, and this is based on one I found at Sally’s Baking and have adapted into multiple different flavor combinations – but this might be the best one yet.

If you don’t have fiori di Sicilia, that’s okay – you can use orange extract for a similar flavor. But I highly recommend visiting King Arthur Baking to buy some – it goes a long way in the flavor department and lasts a while because you only need a few drops, or at most about 1/8 of a teaspoon, at a time. Also, I prefer Cara Cara oranges for most baking, but you can use regular navel oranges if they’re not available.

Ingredients

For the cupcakes

• 1 2/3 cups flour (spooned and leveled)
• 1/2 teaspoon baking powder
• 1/4 teaspoon baking soda
• 1/2 teaspoon salt
• 1/2 cup unsalted butter, melted
• 1 cup sugar
• 1 egg, at room temperature
• 1/4 cup vanilla yogurt
• 3/4 cup milk
• 2 teaspoons vanilla extract
• Zest of 1 medium Cara Cara orange
• Scant 1/8 teaspoon fiori di Sicilia (sub in 1/2 teaspoon orange extract if necessary)

For the frosting

• 12 tablespoons butter, at room temperature
• 3 cups powdered sugar
• 1 teaspoon vanilla extract
• Scant 1/8 teaspoon fiori di Sicilia (sub in 1/2 teaspoon orange extract if necessary)
• 2-3 teaspoons orange juice
• 2-3 drops yellow and red food coloring for orange tint

Preparation

Preheat oven to 350 degrees. Line two cupcake tins with paper liners; my batch made 17 cupcakes.

In a large bowl, combine flour, baking powder, baking soda, and salt; set aside. In a microwave-safe bowl, melt butter, then add sugar and stir to combine; mixture will be grainy. Refrigerate for 1 minute, then remove and add egg, yogurt, milk, vanilla extract, orange zest, and fiori di Sicilia. Stir into the flour mixture until no lumps remain.

Using a 2-inch cookie scoop, scoop batter into tins and fill about 2/3 to 3/4 full. Bake for 20-24 minutes, until a cake tester comes out clean. Remove from oven and place cupcakes on wire racks to cool completely.

To make frosting, beat butter and powdered sugar on low speed until the sugar is fully incorporated into the butter. Add vanilla extract, fiori di Sicilia, and orange juice and beat to combine completely. Add yellow and red food coloring one drop at a time, mixing to reach your desired tint. Fit a large piping bag with a large star tip (I use the Wilton M1) and pipe swirls of frosting onto cupcakes. Store in an airtight container at room temperature for 2-3 days.
