Lemon cheesecake with lemon curd bars have a lemon cookie crust, a creamy cheesecake filling and lemon curd swirled into the top before baking for a rich and tangy flavor.
Using a double boiler or large stock pot and mixing bowl, bring about 2 inches of water to a boil.
Meanwhile, in the top of your double boiler (or mixing bowl), combine the egg yolks, sugar, lemon zest, salt and lemon juice. Whisk to combine.
When the water reaches a boil, put the top in position and keep stirring often. As the egg mixture warms up, the sugar will dissolve, get sticky and then thicken.
Keep mixing and cooking for about 10 minutes or until thickened and pale yellow in color.
Remove from the heat and mix in the butter until the butter has melted and thoroughly combined.
Transfer the lemon curd mixture into a bowl and cover with plastic wrap touching the top of the curd.
Refrigerate until ready to use.
Prepare the Cheesecake Crust
Line an 8-inch square pan with parchment paper and set aside. Preheat the oven to 325°F.
Use a food processor to crush your Oreo cookies into a fine crumb.
In a mixing bowl, combine the crushed Oreos, lemon zest and melted butter.
Stir to combine until it looks like wet sand.
Press the crumb mixture into the bottom of the prepared pan and bake for 10 minutes.
Let it cool to room temperature.
Make the Cheesecake Filling
In the bowl of a stand mixer, cream the sugar, softened cream cheese and lemon zest until smooth.
Add the eggs and mix until thoroughly combined, scraping down the sides as needed.
Add lemon juice and vanilla extract. Mix well, scraping down the sides frequently.
Assemble and Bake the Cheesecake Bars
Spread the cheesecake filling evenly over the cooled crust in the pan.
Dollop spoonfuls of the chilled lemon curd over the cheesecake filling.
Swirl the curd through the filling with a butter knife.
Bake for 45 to 50 minutes or until the edges are set but there’s still a slight jiggle in the center.
Allow the cheesecake bars to cool to room temperature.
Refrigerate 4 hours or until chilled and completely set, then slice and serve.
Notes
Keep refrigerated and eat within 3 days.
Cool the crust first: Let the crust cool before adding the filling, or the cheesecake layer can start softening and sliding on the hot base.
Soften the cream cheese fully: Even small cold bits can leave lumps in the batter, and those don’t bake out.
Don’t over-swirl the curd: A few passes with a knife are enough. Too much swirling just muddies the yellow pattern.
Bake for slight jiggle only: Pull the pan when the edges look set and the center still moves a little. That gives a better texture after chilling.
