Blueberry lemon custard bars are a perfect sweet summer treat! Fresh blueberries are layered over a sugar cookie crust and a rich and creamy custard for an amazing dessert.
Heat oven to 350°. Spray the bottom of 9x13 in pan with non stick spray.
In medium bowl, stir cookie mix, butter, flour and 1 egg until crumbly dough forms. Press firmly into the 9x13 pan.
Top the crust with the blueberries.
In a medium bowl, whisk the eggs, flour, sugar, cream, lemon zest and salt just until smooth. Pour the custard over the blueberries.
Bake at 350° for 50-60 minutes. The center will still be a little jigly, but the edges should be set. Allow to cool to room temperature before serving.
Store refrigerated.
Notes
If you use frozen blueberries, thaw and pat them dry before adding them to the dish.
