Preheat the oven to 350 degrees Fahrenheit (180 degrees Celsius). Line a metal cupcake pan with paper liners and set aside.
Raspberry Ganache
Add freeze-dried raspberries to a food processor or blender. Pulse into a powder. Use a fine mesh sieve to sift out the seeds.
17 grams freeze dried raspberries
Microwave the white chocolate chips in a large bowl for 30 seconds. Add the raspberry powder.
315 grams white chocolate chips
In a separate bowl, microwave the heavy cream for 1-2 minutes until the edges simmer. Pour the hot cream over the white chocolate and let sit for 30 seconds.
220 grams heavy cream
Whisk everything together until the mixture is creamy and smooth. If it's still chunky, blend with an immersion blender until smooth.
Cover the bowl with plastic wrap and chill in the refrigerator for at least 2 hours.
Pistachio Cupcakes
Add cake flour, sugar, pistachios, baking powder, and salt to a large mixing bowl. Mix on low speed with a hand mixer or stand mixer with the paddle attachment until combined.
Add the softened butter and beat on low for 3-5 minutes until the texture looks like wet sand.
76 grams unsalted butter
Add the oil, eggs, vanilla, and almond extract. Mix on low until a thick batter forms. Scrape down the sides of the bowl with a rubber spatula.
80 grams vegetable oil, 2 large eggs, 2 teaspoons vanilla extract, ½ teaspoon almond extract
While mixing on low speed, stream in the buttermilk and stir until well combined. Add food coloring if desired. The batter will be thin.
180 grams buttermilk, ¼ teaspoon green food coloring
Scoop the batter into the cupcake liners, filling each ⅔ full. Bake for 18-20 minutes or until a toothpick inserted in the center comes out clean with a few moist crumbs.
Remove the cupcakes from the oven and let cool in the pan for 10 minutes. Transfer to a wire rack to cool completely for 30 minutes-1 hour.
Assembly
Once the cupcakes are cool, cut out the centers and fill with 1-2 teaspoons of raspberry filling.
170 grams raspberry cake filling
After the ganache thickens, beat on medium-high speed with a hand mixer for 2-3 minutes until fluffy.
Transfer the whipped raspberry ganache to a piping bag fitted with a star piping tip. Pipe a swirl on top of each cupcake. Garnish with fresh raspberries and pistachio crumbs. Enjoy!
