Preheat the oven to 350F. Line 18 regular muffin cups with paper liners.

In a medium bowl, mix the flour, baking powder and salt; set aside. In a large bowl, beat the sugar and the butter with an electric mixer on medium speed. Add the eggs, 1 at a time, beating well after each addition. Beat in the extracts. On low sped, alternately add the 1/3 of the flour mixture, 1/2 of the buttermilk, another 1/3 of the flour, the remaining buttermilk and then the remaining flour, beating just until blended. Stir in the coconut.

Divide batter evenly among muffin cups, filling each about 2/3 full.

Bake for 16 to 18 minutes, or until a toothpick inserted in the middle comes out clean. Cool for 5 minutes; remove to a cooling rack to cool completely.

Once cool, use a sharp knife to cut a cone out of the center of each cupcake, reserving the cut out piece. Fill the center with 1 teaspoon of jam. Replace the cut out piece of the cupcake. Repeat with the remaining cupcakes.

In the bowl of a stand mixer, beat the butter until light and fluffy, 2-3 minutes. With the mixer on low, add the powdered sugar, 1/2 cup at a time, mixing until incorporated. Beat in the salt, then turn the mixer to medium-high and beat until light and fluffy, another 2-3 minutes. Add the jam and beat until combined. The buttercream should be light, creamy and smooth.

Pipe the frosting onto the cupcakes. Top with the toasted coconut.
