These raspberry white chocolate cupcakes have a moist vanilla cake base filled with homemade raspberry jam, and then topped with fluffy white chocolate raspberry buttercream!
Add the fresh or frozen raspberries to a large nonstick pot over medium heat. Add in the sugar and stir to combine.
Cook gently over medium heat for 5-10 minutes or until the raspberries begin to break down.
Mix together the cornstarch and water to make a slurry and then slowly add to the raspberries until thickened. Remove from the heat and set aside.
Cupcakes
Whisk the cake flour, baking powder, and salt together in a large bowl.
In a separate bowl, whisk together the melted butter and sugar.
Then add in the eggs and vanilla whisk until fully combined.
Stir in about half of the flour mixture. Then stir in the milk and the rest of the flour mixture and mix until fully combined.
Pour about ¼ cup of batter into each cupcake liner (they should be about halfway full).
Bake at 350°F for 18-22 minutes or until a cake tester comes out clean.
Remove from pan and let cool on wire rack.
Let the cupcakes cool completely before filling and frosting.
Use a cupcake corer to remove the center of each cupcake, then fill with 1-2 teaspoons of cooled raspberry jam.
White Chocolate Raspberry Buttercream
Melt the white chocolate and let cool almost to room temperature. It should be melted but cool to the touch. I prefer to melt the chocolate in the microwave in intervals of 20 seconds, stirring each time.
In a large bowl using a handheld or stand mixer fitted with a paddle attachment, cream the butter and powdered sugar together until smooth.
Set the mixer to low speed and slowly drizzle in the melted white chocolate until it's fully incorporated into the buttercream.
Add in 1-2 tablespoons of the raspberry jam (to taste). If desired, pass through a fine mesh strainer first to remove the seeds.
Then beat on high speed for 3-4 minutes or until the buttercream is super light and fluffy.
If the frosting in too thick, add in 1-2 teaspoons of cream at a time to thin it out a bit.
Frost the filled cupcakes with white chocolate raspberry buttercream and then garnish with fresh raspberries and white chocolate shavings.
Notes
These cupcakes will last in the fridge for up to 3 days. However, they taste best when served at room temperature! I like to let them sit at room temperature for about an hour before serving.
