["1) Preheat your oven to 400 degrees F. Line a baking sheet with parchment. Spread your hazelnuts out into a single layer and toast until fragrant and just golden, about 8-10 minutes. Once cool enough to handle, rub them together in a clean kitchen towel to remove the skins. Place in your food processor and grind to a medium fine meal. Set aside.", "2) In a stand mixer, cream your butter and sugar with the paddle. Sift together the flour, cinnamon and baking powder. Add in your ground hazelnuts. Stir to combine.", "3) Add eggs, one at a time to the butter/sugar mixture, scraping down the bowl between additions until well combined. Stir in the vanilla extract. Add the dry ingredients, 1/2 at a time, until just combined. Pat the finished dough into a disk (or two) and wrap tightly in plastic wrap. Store in the refrigerator at least 2 hours before using or overnight (ideal). Any extra dough can be frozen for up to 3 months.", "To assemble and finish the cookies:", "1) Preheat the oven to 325 degrees F. Line 2 baking sheets with parchment. On a well floured board, working in batches, roll out your dough to 1/8"" thick. Use a 3"" heart shaped cutter to cut out the bottoms of the cookies. Use a 2"" fluted heart shaped cutter to cut out the windows in the tops of the cookies. Make sure that you cut out equal quantities of cookie tops and cookie bottoms.", "2) Place the cookie cutouts on your lined baking sheets and refrigerate the dough until chilled, about 15 minutes. Bake the chilled dough until just golden, about 12-15 minutes, taking care not to overbake.", "3) While the cookies are cooling, heat the raspberry jam & 2 teaspoons of sugar in the microwave. The jam should come to a full boil. Remove it and give it a quick stir. Sandwich the pairs of cookie tops and bottoms together. Pour the hot jam into a piping bag and flood the window of the cookies with the hot jam. Yes, it's hot and yes, it burns your hands while piping. Alternately, you can spoon the jam into each window, taking care not to get any on the sides of the cookies.", "4) Once the cookies are sandwiched together and filled with jam, and while the jam is still warm (that part is important!), sift the powdered sugar over the top of the cookies. If the jam is still warm, it will melt the powdered sugar and leave you with a clear, red raspberry window and will adhere to the outside of the cookies only.", "Let the jam and cookies cool completely and enjoy! These can be stored in airtight bags up to 3 days."]
