How To Make Martha Stewart Blueberry Crumb Cake
- Preheat oven and prep pan: Preheat oven to 350°F. Butter a 13-by-9-inch baking pan.

- Add eggs and vanilla: Beat in the eggs one at a time until fully incorporated. Mix in the vanilla extract.
- Add flour and sour cream: Add the dry ingredients and sour cream to the wet mixture. Beat just until combined.
