To make the pie dough: In the bowl of a stand mixer fitted with the paddle attachment, add the flour and cane sugar. Turn on low for two to three rotations to combine the dry ingredients.
Remove the butter from the fridge and chop into small cubes. The smaller the cubes, the flakier the crust: Cut the stick of butter into four and then chop into small cubes from there. Add the cold, cubed butter to the flour mixture. Measure out the cold water and have it ready.
Turn the mixer on low and slowly start to incorporate the ingredients. Gradually turn the mixer to medium speed. Once the butter mixture looks like wet sand, immediately add in all the ½ cup cold water. As soon as the dough comes together, stop the mixer.
Form the dough into a disk and wrap in plastic wrap. Allow to cool in the fridge for at least 6 hours or overnight before rolling out the pies.
Line a baking sheet with parchment paper.
Add 2 tablespoons of water into a small dish.
Remove the plastic wrap from dough and place on a lightly-floured surface. Roll out to 1/4-inch thick. Using a 4 ½-inch cookie cutter or pastry cutter, cut out 10 circles and transfer 5 of them to the prepared baking sheet.
In a small bowl, add the jam and cornstarch and mix together.
Add about 1 ½ tablespoons of the jam mixture onto the center of each circle on the parchment paper, leaving a small boarder. Using your hand, dip your finger into the water and go around the boarder of one of the pie circles. Then immediately place one of the additional dough circles, using the water to seal it together. Repeat with the rest of the pies so each one is topped.
Place the baking sheet in the fridge for 15 to 20 minutes, until the dough is firm. Preheat the oven to 400°F.
In a small dish, add the remaining 1 tablespoon of water and 1 tablespoon of honey. Microwave for 10 seconds until the honey has melted and you can easily combine the ingredients.
Remove the baking sheet from the fridge and using a fork, crimp the edges around the top of each hand pie. Brush the top of the crust with the honey and water mixture and make one vent hole in the middle.
Bake for 25 to 30 minutes, or until golden brown. Let cool completely on the baking sheets.
To make the glaze: In a small bowl, add the powdered sugar, pink dye, and water and whisk together until you have a smooth glaze. Using a butter knife, spread glaze the on top of the pies.
Top the glaze with sprinkles.
Store in a cool, dry place for up to 3 days.
