1cup2 sticks unsalted butter, cut in cubes and frozen
For the Filling
For the Frosting
2 ½cupspowdered sugar
5tablespoonsmilknot heavy cream
4tablespoons½ stick unsalted butter, room temperature and cut in cubes
In a food processor, add the dry ingredients and pulse to combine. Add the butter and pulse again until the mixture resembles very coarse crumbs. In a separate bowl, add the wet ingredients and mix until just combined. Add the wet ingredients into the food processor and mix until dough just begins to form.
Turn the dough onto a light floured surface and knead gently until the dough comes together. Divide in two and form into discs. Wrap each disc in plastic wrap and chill in the refrigerator for about 2 hours.
Preheat the oven to 350 degrees F. Line a baking sheet with parchment paper.
Take out one of the discs and roll out into a rectangle about ¼ inch thick. Cut out rectangle that are 3 x 4 inches. Take any scraps and form into another disc, rewrap in plastic and place in the fridge. Repeat with the second disc. Keep repeating with the discs until all the dough is used. Be sure to keep re-chilling the scraps before rerolling. The dough is very sticky and can be difficult to work with if the dough warms too much. You should end up with about 20 rectangles.
Mix the Nutella and heavy cream together. Place about two tablespoons of the Nutella on the center of half the rectangles and spread out, leaving a 1 -2 centimeter border. Place the other half of the rectangles on top of the Nutella halves and press the edges down with a fork to seal. Prick the tops of the pop tarts with your fork several times.
Bake for about 10 – 12 minutes. Allow to cool completely.
Mix together the powdered sugar and cocoa powder for the frosting. Stir in the milk and extracts. Beat in the butter until smooth. Spread a thin layer of frosting onto the pop tarts and sprinkle with chocolate sprinkles if using. Allow the frosting to dry. (We couldn't wait for the frosting to dry and it tastes amazing with fresh frosting.) Alternatively, you can just slather on some more Nutella on top - just sayin'!
