Preheat the oven to 325°F. Line an 8x8 baking pan with foil or parchment paper, set aside. Mix the crushed oreos with the butter and press into the pan.
In a large bowl with a hand mixer, or in the body of a stand mixer with the paddle attachment, add the cream cheese to the bowl and mix on medium until there are no lumps. Add the sour cream, sugar, vanilla, egg, flour, lemon juice, and lemon zest. Mix until combined on medium speed, scrape down the sides of the bowl as needed. Add 3/4 of the blueberries and fold them in, pour into the 8x8 pan on top of the crust. Top with the remaining blueberries.
Bake for 36 minutes, until the center is very slightly jiggly and the edges start to brown. Let the pan cool completely on the counter, cover, and chill in the fridge for 4 hours or up to overnight to set. Cut, serve, enjoy, garnish with whipped cream, lemons, and blueberries, optional.
