Strawberry Crumb Bars

I found this recipe via Pinterest.
I made some modifications based on what I had in the house, and it was awesome.
A perfect summer dessert, I brought it to a 4th of July BBQ.

ingredients
1½ cups sugar, divided
1 tsp baking powder
3 cups all-purpose flour
¼ tsp salt
2 sticks (½ lb) cold salted butter, cut into pieces
1 large egg
4 cups fresh strawberries, hulled and quartered
4 tsp cornstarch
2 tbs lime juice

directions

1. Preheat the oven to 375° F. 
2. Grease a 13×9 inch pan; set aside.
3. In a medium bowl, combine 1 cup of the sugar, the baking powder and flour.  Mix in the salt, stir together with a fork.  Cut in the butter and egg with a pastry blender (or two knives if you don’t have one) until the largest chunks are about pea-sized.  The mixture should be crumbly without much loose flour.
4. Spread about half of the dough mixture in an even layer over the bottom of the prepared pan and press down firmly to form the bottom crust.
5. In another bowl, stir together the remaining sugar, cornstarch and lime juice.
6. Gently mix in the strawberries with a rubber spatula until combined.  
7. Spread the berry mixture evenly over the bottom crust.  Crumble the remaining dough over the top of the berries. 
8. Bake for about 45 minutes or until the top is slightly golden brown.
9. Cool completely before cutting into squares and serving.
10. Enjoy!
