Step‑by‑Step Instructions for Moist Pistachio Cupcakes with Luxe Meringue Frosting
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (180°C). Line a muffin tin with your favorite cupcake liners, ensuring they are set firmly in place. This initial step will set the stage for perfectly baked moist pistachio cupcakes, so take your time to get everything ready for the delicious journey ahead.
Step 2: Cream the Butter and Sugar
In a large mixing bowl, cream together the softened unsalted butter and granulated sugar using a hand mixer or stand mixer. Beat the mixture on medium speed until it becomes fluffy and pale, which should take about 3-5 minutes. This aeration is essential for light and airy cupcakes, so pay close attention to the texture.
Step 3: Incorporate Wet Ingredients
Add in the large egg and sour cream to the fluffy butter and sugar mixture. Mix on low speed until well combined. You should achieve a smooth batter with a velvety consistency. This delectable blend contributes to the moistness of your pistachio cupcakes, igniting the flavor profile you’re aiming for.
Step 4: Sift and Combine Dry Ingredients
In a separate bowl, sift together the all-purpose flour, baking powder, baking soda, and salt. This ensures even distribution and prevents clumps. Gradually incorporate the dry mixture into the wet batter, mixing on low speed while alternating with the milk. This step should result in a smooth batter, ready to showcase the vibrant pistachio flavor.
Step 5: Add Flavors and Texture
Next, mix in the pistachio paste, vanilla extract, and almond extract, stirring just until blended. Fold in the chopped pistachios gently with a spatula. These final touches add depth to the batter of your moist pistachio cupcakes, promising delightful bites filled with nutty goodness.
Step 6: Bake to Perfection
Carefully distribute the batter evenly into the lined cupcake tins, filling each liner about two-thirds full. Place them in the preheated oven and bake for 17 minutes, or until a toothpick inserted into the center comes out clean. Once baked, allow your cupcakes to cool in the tin for a few minutes before transferring them to a wire rack to cool completely.
Step 7: Prepare the Meringue Buttercream
While the cupcakes cool, start making the Italian meringue buttercream. In a clean mixing bowl, whip the egg whites until they become foamy. Gradually add a pinch of salt and superfine sugar, mixing on medium-high speed until soft peaks form, resembling cloud-like fluff that’s ready to hold its shape perfectly.
Step 8: Make the Sugar Syrup
To create the sugar syrup, combine the remaining superfine sugar and water in a small saucepan. Heat over medium until the mixture reaches a temperature of 240°F (115°C), using a candy thermometer for accuracy. This crucial step ensures the meringue achieves stability and glossiness when combined, bringing your buttercream to luxurious heights.
Step 9: Combine Meringue and Syrup
Once your sugar syrup has reached the desired temperature, slowly stream the hot syrup into the whipped egg whites while the mixer runs on medium speed. Continue whipping until the mixture cools down to room temperature, achieving a thick and glossy meringue—this is the foundation for your decadent buttercream.
Step 10: Fold in Butter and Flavor
Gradually add the softened unsalted butter to the meringue mixture, one piece at a time, beating on low speed until fully incorporated. Follow this with the pistachio paste, mixing until the buttercream is silky and smooth. This velvety pistachio Italian meringue buttercream will elevate your cupcakes to extraordinary levels.
Step 11: Frost and Decorate
Once the cupcakes are completely cooled, generously frost each one with your luscious pistachio Italian meringue buttercream using a piping bag or spatula. Feel free to get creative with your decorations by adding extra chopped pistachios on top or even using edible flowers for that beautiful finishing touch.
Step 12: Serve and Enjoy
Your moist pistachio cupcakes with luxe meringue frosting are now ready to be enjoyed! Serve them at a gathering or simply indulge yourself on a cozy afternoon. The combination of soft cupcake texture and creamy frosting will surely impress everyone who takes a bite.

Pistachio Cupcakes Recipe FAQs
How do I select ripe pistachios for my cupcakes?
Absolutely! When choosing pistachios, look for ones that are bright green with a slightly creamy hue. They should be firm to the touch and mostly intact; avoid any with dark spots or a shriveled appearance, as these often indicate they are old or stale.
How should I store leftover cupcakes?
Certainly! Unfrosted pistachio cupcakes can be stored in an airtight container at room temperature for up to 2 days. If they’re frosted with the Italian meringue buttercream, it’s best to refrigerate them in an airtight container for up to 5 days to maintain freshness and texture.
Can I freeze the cupcakes and frosting?
Yes, you can! For freezing, place unfrosted cupcakes in an airtight container, layering them with parchment paper, and freeze for up to 3 months. The buttercream can also be frozen for up to a month; just ensure it’s at room temperature when ready to use and rewhip to restore its smooth texture before frosting.
What should I do if my meringue seems runny?
If your meringue buttercream looks soupy, don’t worry! Continue whipping it vigorously. Sometimes it takes a bit longer to come together, but with persistence, it will transform into that luxurious consistency you’re aiming for. If you’ve just added the butter, whip on high speed for a few extra minutes; heating it with a warm bowl can help stabilize it.
Are these cupcakes suitable for people with nut allergies?
For sure! If you’re making these delicious pistachio cupcakes for someone with nut allergies, consider using sunflower seed butter and omit the chopped pistachios entirely. This will create a nut-free version while still maintaining a delightful flavor profile. Always check ingredient labels for any hidden allergens!
Can I adjust the sweetness of the frosting?
Certainly! If you prefer a less sweet buttercream, feel free to reduce the sugar in the meringue by a couple of tablespoons. Remember, however, that the sweetness beautifully complements the rich flavor of the pistachios, so adjust carefully to keep that balance.
