Once again, I apologize for the quality of the photos. I just can't shoot with my left hand and the light in my kitchen is awful. These are much better than they look!
Crack 4 eggs into your mixer bowl.
Add 1 cup of sour cream.
Add 2 cups of flour and a pinch of salt.
Add the zest of 1/2 lemon and 1 tsp. of almond extract. Beat until mixed thoroughly.
Add 2 large containers of fresh blackberries.
Gently stir them into the batter.
I forgot some photos again. Place 3 cups of flour in the bowl of your food processor. Add 1 1/2 cups of sugar and 1/4 tsp. of salt. Pulse to mix. Cut 3 sticks of butter (1 1/2 cups) into 1/4 inch cubes. Pulse the processor as you drop the butter in. Pulse until you have a crumbly mix. Reserve 1 1/2 cups of this for your topping. Press the remaining into a 9 X 13 inch pan which has been coated with cooking spray. Bake this for 15 minutes at 350 degrees. Let it cool for 15 minutes.
Pour the berry batter over the top and crumble the 1 1/2 cups of the topping over it. Bake at 350 degrees for 45-55 minutes. It should be set in the middle.
Remove from the oven and let cool for an hour before cutting into bars.
