Preheat oven to 350 degrees

Grease a 9x9 baking dish

In a large bowl, whisk flour, sugar, and salt. Add softened butter until combined.

In a separate bowl, whisk together eggs, lemon juice, lemon zest and vanilla extract.

Pour egg and lemon juice mixture into dry ingredients until just combined.

Fold in raspberries and then pour into baking dish.

Bake for 45 minutes or until inserted toothpick comes out clean. (Half way through baking time check to see if the coffee cake is browning too much. If it is, cover with foil the rest of the baking time.)

Using a food processor or blender, pulse all ingredients until light and fluffy.
