Blueberry Bars Recipe

The initial preparation includes making the cake bottom and a crumb topping mixture. We start with mixing together dry ingredients in a large bowl. Make the crumb mixture by blending the room-temperature butter into the flour mixture (a pastry blender or two knives can help with this process). Transfer 2 cups of the crumb mixture to another bowl reserving for the topping. Blend the egg white into the remaining crumbs and press the mixture into the bottom of the pan. It helps to use the bottom of a measuring cup to press down the crumbs to even it out. Bake the crust until it starts to form a dry top, 10 to 12 minutes. While the cake is baking, rinse the blueberries and dry on paper towels. 

While the cake is baking, make the lemon-cream filling by whisking together the condensed milk, lemon juice, lemon zest, and egg yolk. Let this mixture stand for 5 minutes; it will begin to thicken.

Take the cake out of the oven once the crust is formed. Sprinkle the blueberries evenly over the hot crust. Drop spoonfuls of the lemon-cream filling over the blueberries. Gently distribute with a spatula, but be careful not to crush the blueberries. Do not worry about it being perfect. Return the cake to the oven and bake until the lemon mixture just begins to form a shiny skin, 7 to 8 minutes.

Topping the Blueberry Bars

Take the cake out of the oven and sprinkle the crumb topping over the lemon-blueberry layer. Press the crumb topping between your fingers into small lumps as you sprinkle. Return the cake to the oven and bake until the filling is bubbling at the edges and the topping is brown, 25 to 30 minutes. Let the blueberry bars cool on a rack until just warm, about an hour. Carefully lift them out of the pan using the parchment paper overhang and transfer to a wire rack to cool completely. Remove the parchment paper and cut into 24 bars when cool. The bars may be stored at room temperature for a few hours but otherwise should be kept in the refrigerator.

Tips

The crumb topping is rather dense in texture. The excess topping shakes off the bars and is a bit messy! If you would like more of the blueberry lemon filling then reduce the amount of crumb mixture when topping the bars. Before serving warm the bars in the microwave to enhance the flavors. A scoop of vanilla ice cream goes nicely with warm Blueberry Bars!

Lastly, room temperature blueberries is better for the cooking time. Overall baking time is about 50-minutes. Cooling time before serving is about an hour. So planning ahead is important.
