Preheat oven to 425 degrees.

Unfold the puff pastry sheets and cut into 1/2"-1" strips with pizza cutter. While I didn't in this photograph, I encourage you to then cut the sticks in half length wise. The best way I can describe it is that the sticks cook more sturdy and less airy.

Place the sticks on parchment paper on a cookie sheet about 1/2" apart.

Bake 10-12 minutes until golden brown.

Now, there are 2 options for covering with the sweet stuff: 1 Dip the sticks into melted butter and then roll into the cinnamon and sugar mixture until covered. Set aside for a few minutes to set. OR 2. Brush the sticks with melted butter using a pastry brush and toss cinnamon and sugar mixture on top. Once done with each, carefully flip and do the back.
