How to Make Brown Sugar Cinnamon Poptart Bars
- Preheat the oven to 325°F and line an 8x8 baking dish with parchment paper. In a bowl, beat 2 sticks of butter until fluffy. Mix in 1 tsp. vanilla and 1 ½ c. powdered sugar until smooth.
- Add the egg, then mix in 2 ½ c. flour, for dough, and salt until a dough forms. In a separate bowl, stir together brown sugar, 2 tbsp. cinnamon, 4 tbsp. flour, for filling, 4 tbsp. melted butter, and 1 tbsp. vanilla until combined.
- Press half the dough evenly into the baking dish. Spread the filling on top, then press the remaining dough over the filling. Flatten it with oiled hands if needed.
- Bake for 40 minutes or until the center is set (check with a toothpick). Let the bars cool for 40 minutes.
- Combine 1 c. powdered sugar, 2 tsp. cinnamon, and 3 tsp. vanilla to make the icing. Spread evenly over the cooled bars.
- Let the icing set for 15 minutes (or skip if you prefer them gooey), then slice into bars and enjoy!

Pro Tips For Making This Recipe
- If your dough feels too sticky to handle, pop it in the fridge for 10-15 minutes before pressing it into the pan. This makes it easier to work with and less messy.
- Make sure your butter is fully at room temperature before beating it. This ensures a light, fluffy texture for the dough and makes it easier to mix.
- Allow the bars to cool fully before adding the icing. If they’re still warm, the icing will melt and become runny instead of creating a smooth, spreadable layer.

Frequently Asked Questions
