Place the butter in a light-colored skillet. Melt the butter over medium heat, stirring occasionally. Once melted, the butter will begin to foam. Keep stirring occasionally.
½ cup unsalted butter
After 5-8 minutes, the butter will begin browning. There will be lightly browned specks forming at the bottom of the pan and it will have a nutty aroma.
Once browned to an amber color, remove from heat immediately and allow the butter to cool until solid, but still soft, like a thick paste.
In the bowl of a stand mixer fitted with the paddle attachment, combine the cooled brown butter, and the cream cheese. Mix until thoroughly combined.
1 cup cream cheese, room temp
Mix in the confectioner's sugar, a cup at a time, mixing after each addition until combined.
4 cups confectioners sugar
Add the salt and the vanilla.
¼ teaspoon fine sea salt, 2 teaspoons pure vanilla extract
Turn the mixer up to medium speed, and whip for 3 minutes. Scrape the bottom and sides of the bowl. Whip again for another 2 minutes.
Using a sharp knife, cut a hole into the center of the cooled cupcakes to create a space for the apple filling. The piece you removed will be the shape of a cone.
Spoon the apple filling inside each carved out cupcake, filling the cupcake to the top. Slice off the pointy end of the cone piece you removed so that it can fit on top of the filling. Place on top of the filling.
Use a large ice cream scoop to scoop heaping portions of the frosting onto each of the cupcakes.
Use a small, offset spatula to smooth out the frosting to the edges, while still maintaining the dome shape.
Place the peanuts in a shallow bowl. Roll the sides of the cupcakes through the peanuts.
¾ cup roasted, salted peanuts, finely chopped
Drizzle the salted caramel sauce over the cupcakes. Insert a popsicle stick or cake pop stick into the center.
