White Chocolate Lemon Bars

I have been quite a slacker lately when it comes to cooking anything or making any new recipes.  In 7 weeks I made 6 cakes, the last being a 3-tiered wedding cake for friends.  I was very, very busy.  And after the last cake, I didn't want to do anything.  But someone asked for the recipe for lemon bars I made her last year, only I didn't actually have a recipe.  Once again I was playing around and didn't bother to write anything down.  So I decided to try to recreate my lemon bars.  I'm pretty happy with the results.  Enjoy!

White Chocolate Lemon Bars

2 c flour
3/4 c sugar
2 tsp. baking powder
1 tsp. vanilla extract
1 Tbls milk
1/2 c unsalted butter
1/2 c lemon juice
1 Tbls lemon extract
1 14oz can sweetened condensed milk
4 egg yolks
6 oz white chocolate
1/4 c whipping cream

Preheat oven to 350 degrees.  Line a 9x13 pan with aluminum foil and light grease it.  Set aside.
In a large bowl, sift together flour, sugar and baking powder.  Sprinkle vanilla and milk over the flour mix.  Cut in butter until small crumbs form.  Press the crumb mixture into the bottom of the pan evenly.  Bake for 12-15 minutes until the edges start to brown slightly.  As that is baking, whip together lemon juice, lemon extract, sweetened condensed milk and egg yolks.  Pour the egg mixture over the crust when it comes out of the oven and carefully spread.  Return to the over for 15-20 minutes or until the filling is set.  Cool on wire rack for 1 hour, then chill for 30 minutes.  As that is chilling, boil the whipping cream over medium high heat.  Remove from heat and add in chopped white chocolate. Stir until smooth.  Cool about 5 minutes before spreading over the lemon bars.  Cover and chill addition 1 hour before cutting.
