Preheat oven to 325℉ and prepare a 9x13 pan with parchment paper and oil
Combine blended pretzels, butter, and sugar. It should resemble wet sand. Press this mixture along the bottom of your prepared pan and set aside
In a separate bowl, whisk together brown sugar and maple syrup. Once combined, add vanilla and salt and continue whisking.
Add eggs and whisk thoroughly.
Sift flour and cornstarch lightly overtop the mixture. Whisk vigorously until no clumps of flour remain. Add pecans and stir.
Pour overtop the crust and bake for 20-25 minutes or just until the middle is set.
Let cool completely
Once cool beat cream cheese and sour cream together until fluffy. Add powdered sugar and lemon juice and beat until smooth.
In a separate bowl beat heavy cream until peaks hold their shape but are not too stiff, stiff peaks have a larger chance of over whipping in this recipe
Add half the whipped cream to the cream cheese mixture and beat on high for 30 seconds. Add the last half and beat again for 30 seconds to a minute. The mixture should be thick and hold its shape.
Spread evenly over the cooled pecan layer. Wrap pan in cling wrap or foil and refrigerate over night.
Once set over night, cut into as many pieces as you wish and serve!
