Easy Raspberry Crumble Bars

Ingredients:
1/2 cups sugar
1 tsp. baking powder
3 cups all-purpose flour
1 teasp. salt
Zest of 1 lemon
1 cup unsalted butter
1 egg
4 cups frozen raspberries
5 tsp. bread crumbs
Juice of 1 lemon

Preheat the oven to 375° F/ 190°C.

In a bowl mix 1 cup of the sugar, baking powder and flour. I added a teaspoon of vanilla-flavoured sugar because I love it but you can leave that out.
Mix in the salt and the lemon zest, and stir together with a fork.
I usually melt the butter for a minute in the microwave so it's easier to mix. Add in the butter and egg and mix well. The mixture should be crumbly without much loose flour. Spread around 2/3 of the dough mixture in an even layer over the bottom of a greased rectangular pan and press down firmly to form the bottom crust.

In another bowl, stir together 1/2 cup of sugar, bread crumbs or cornstarch and the lemon juice. Mix in the raspberries. Sprinkle the berry mixture evenly over the crust. Crumble the remaining dough over the top of the berries.
Bake for about 45 minutes or until the top is slightly golden brown. Cool before cutting into squares and serving. Sprinkle a little powdered sugar on top and serve.

I used more sugar because raspberries are not as sweet as blueberries and used bread crumbs instead of corn starch because I had it lying around. Needed extra 10 minutes to cook.
