Instructions
To start preheat the oven to 350 degrees.
Butter and line an 8" square baking pan with parchment paper. Butter the paper and flour. Dump out excess flour.
Now let's start on the crumb topping.
In a medium mixing bowl add the melted butter, brown sugar, 1/4 tsp salt, and 1 cup of flour. Stir with a fork until crumbles form. Refrigerate until time to use.
Moving on to the filling. Start by mixing the remaining flour in a medium bowl, 1/4 tsp sea salt, and baking powder.
Now in a mixer or large bowl with a hand mixer, add 1/2 cup room temperature butter. Beat with powdered sugar and vanilla extract.
Mix until light and fluffy. Add eggs in 1 at a time. Blend well.
Scrape down the sides of the bowl and pour into the prepared baking pan. Spread evenly.
Sprinkle on the blackberries.
Next goes the crumb topping. (A little sprinkle of the toasted vanilla sea salt if you, have it)
Bake for 40 minutes. The topping should be a light golden brown and a toothpick comes out clean.
Let the pan cool for 5 or so minutes then pull out the crumb. Let it cool completely.
