Homemade Pop Tarts

For the Pop-Tart:

1. In a food processor, pulse together flour, salt and granulated sugar. Add butter and pulse mixture until resembles coarse meal (it won't really come together in pieces much at this point, so don't over-process, just pulse until butter is no longer in large pieces).
2. Add 4 Tbsp water and pulse several times, if it doesn't come together in clumps add remaining 1 Tbsp water. Drop mixture onto a clean surface, gather dough into a ball then divide into two portions. Shape each portion into about a 5-inch disk. Cover each with plastic wrap and chill 1 hour.
3. Line two large, rimmed baking sheets with parchment paper. Working with 1 disk at a time (keep other in fridge to chill), roll dough out onto a floured surface to about 13 by 11-inch rectangle (when edges start to crack a little when rolling, seal them and continue rolling), then trim edges to get a 12 by 10-inch rectangle (to even the edges). Then cut into eight 5 by 3-inch rectangles (cut in half through the longness then three cuts through the opposite).
4. Arrange 4 of the rectangles, spaced evenly apart on prepared baking sheet. Spread 1 1/2 Tbsp of jam evenly down the center of each rectangle, leaving about a 3/4-inch rim on all sides uncoated.
5. Top each with another rectangle, then seal edges with your fingertips, then reseal with a fork. Poke the top center of each tart about 4 times with a toothpick. Cover and transfer to freezer to chill at least 2 hours or up to one week. Repeat process with remaining disk of dough.
6. Position one oven rack near top third of the oven and a second oven rack near bottom third of the oven. Preheat oven to 375 degrees. Bake frozen tarts until golden, rotating racks once halfway through baking, about 25 - 30 minutes (some of the preserves may leak out, which is fine, just peel it off once it cools). Allow to cool on baking sheet several minutes then transfer to a wire rack to cool completely.

For the icing:

1. In a mixing bowl whisk together all icing ingredients well then add more half and half about 1/2 tsp at a time to reach desired consistency. Spread over tops of cooled pop tarts, leaving a small rim uncoated around all sides. Sprinkle tops with sprinkles if desired and allow glaze to set at room temperature. Store in an airtight container.
