Berry Delicious Dessert

I'm not sure what to actually name this dessert or how to even describe it to you.
I came up with it yesterday while I was *experimenting* in the kitchen and it's a definite keeper.
It's not a cookie obviously, yet the batter reminds me of cookie dough.
It's not a cobbler or a streusel but it makes me think of those desserts also.
Bottom line....IT IS GOOD!
It was our dessert after dinner last night. Some ate it plain, right off of the plate while others had it in a bowl with milk. Both ways were tasty. I refrigerated the leftovers and enjoyed them again tonight after dinner. Served cold, it tasted even more like a cookie.

Berry Delicious Dessert

2 sticks butter
1 cup sugar
2 eggs
1 tsp. vanilla
1/2 tsp. salt
2 cups flour
1 tsp. baking soda
21 oz. can of blackberry pie filling

Glaze:
1 cup powdered sugar
2 tbsp. milk
splash of vanilla

Cream butter and sugar.
Add eggs, 1 tsp. vanilla, salt, flour & soda.
Mix well and spread 3/4 of the dough in the bottom of a greased 13X9 pan.
Spread blackberry filling over batter.
Using a teaspoon, spoon remaining dough on top of the filling. (Just place dots of it here and there.)
Pull a knife through the dots and kind of swirl it a bit.
Bake at 350° for 30-40 minutes.
Cool completely.
For glaze:
Whisk together powdered sugar, milk & the splash of vanilla.
Place icing in a plastic food storage bag, twist it to close and then snip the bottom corner off to create an icing bag.
Gently squeeze icing over the top and ENJOY!
