Pre-heat your oven to 350F.Butter and Line an 8*8 inch square pan with
parchment paper, leaving a 2 inch overhang on the sides and set aside.
In a large bowl combine your melted butter and graham crackers crumbs and mix until they resemble wet sand.
Press the crumbs evenly into your prepared pan using a mug or a measuring cup.
Bake the crust for 10 mins.
In the bowl of your stand mixer or in a large bowl using a hand mixer add cream cheese, flour and vanilla.
Beat on medium speed for 2-3 minutes.
Continue mixing on medium speed, then add 1 egg at a time, mixing for a few seconds in between additions.Stir in the sour cream
Pour the prepared batter into the 8”x8” pan on top of the graham cracker crust.
Dollop teaspoon-fulls of Nutella all over the top of the cheesecake batter and make swirls in the batter using a skewer or knife.
Bake for 30 minutes until the edges of the bars are golden and the middle still has a little jiggle in the middle.
Allow the bars to cool completely in the pan. Remove and place in the fridge to chill for at least 4 hours or overnight.
Slice and enjoy!
