Key Lime Pie Bars

I lost these pictures for a while amongst the other things I baked this summer- but I'm glad to find them again, because these are really delicious. I made them with what was left in the pantry just before departing on vacation as a gift for the family watching our cats, and they were extremely popular from the reviews I got.

You need very few ingredients to put these together, provided you can find key limes- but I think they'd probably be pretty good made with regular Persian limes (or maybe meyer lemons!) instead. Another garnish idea is toasted shredded coconut, seeing as coconut and lime go so well together.

For the Crust:
1- 1 1/4 C. Graham cracker crumbs
5 TBSP Butter, melted
2 TBSP Sugar

Mix all in a food processor until the consistency is that of wet sand. Pat onto the base and sides of a greased and parchment-lined 8"x8" baking tray. Bake for about 10 minutes, or until set firmly.

For the Filling:
1/2 C. Key lime juice
Zest of 6 key limes
4 Egg yolks
14 Oz. Sweetened condensed milk

Mix juice, zest and yolks with a whisk. Stir in milk and keep whisking until thickened. Pour onto the cooled crust and bake at 170℃ until set but still wobbly when poked, about 15-18 minutes.

For the Topping:
1 C. Sour cream
1/4 C. Powder sugar

Mix well and spread on top of the cooled bars.
