Blueberry Poptart Bars

Start by preheating your oven to 350F.

For the Blueberry filling: In a medium saucepan, add your blueberries, granulated sugar, and vanilla. Mix on medium heat for 5 minutes or until blueberries begin to break down. Turn the heat to medium-low and cook for an additional 10-15 minutes or until the filling has thickened. Remove from heat and allow to cool completely.

For the Poptart layer: In a large bowl, combine your soft unsalted butter, brown sugar, and 1/4 cup powder sugar. Mix until butter and sugar are creamed together (a stand or power mixer will be easier). Add in your large egg and 2 tsp vanilla and mix again.

Add in your all-purpose flour and mix until a dough forms. It may seem dry at first, but keep mixing! Split your dough in half and add one half to a lined 8x8 baking dish. Press this dough until it is flat. Take the other half of the dough and press it into an 8x8 square on a piece of parchment paper.

Once your blueberry filling has cooled, add it evenly to your 8x8 baking dish over the first dough layer. Carefully top with the other half of your dough (from the parchment paper).

Bake in the oven at 350F for 40 minutes.

Allow your poptart to cool for 15 minutes before icing them!

For the Icing: In a small bowl, combine 1 cup powder sugar, 1 tsp vanilla, 1 tbsp blueberry filling, and 2 tbsp milk. Whisk until smooth. Spread over cooled poptart bars. Enjoy!
