First, make the microwave lemon curd recipe below, and place it in the fridge.
Next, make the cookies: preheat the oven to 350.
Cream together the butter and brown sugar on medium speed until light and fluffy, about 2 minutes.
Next, add the vanilla and continue beating. Sprinkle in the ginger, cinnamon and nutmeg and beat well.
This is very important: slowly add the flour to the dough while mixing, about 1 tablespoon at a time. If you dump all of the flour in at once, the dough won't come together.
Scoop the dough into 12 teaspoon-sized mounds. Use the end of a small wooden spoon to make a divot in the center of each cookie. Press the edges together if the dough cracks a bit.
Bake for 13-14 minutes, or until the edges of cookies brown slightly.
Move the cookies to a wire rack and cool completely.
Add scoops of lemon curd into the center of each cookie, and serve.
