Delicious crumb bars bursting with fresh blueberries and a hint of lemon!

Lemon Blueberry Sour Cream Crumb Bars stacked on top of one another.
Moving is such a hard thing to do. Me and the hubby have been going non stop for two weeks. Luckily I have been pulling the, “I can’t lift anything” card or I wouldn’t have survived. We have gotten pretty settled into the new place and absolutely love it. And today we celebrated our anniversary. It started in the morning with getting my tire replaced that had a nail in it. Life huh? But then it was so nice to take a break and get a relaxing massage and go out to a nice French Restaurant. It was fun to hear my hubby speak french and tell me stories of his mission in France while we were there. It was great to have a break for a while and enjoy the day with him.

But anyway. Enough about my life. Lets talk about how bomb diggity these bars turned out! This is my favorite recipe for crumb bars. They have such a great shortbread like base to them. But the crumb topping is perfect. It is the perfect crumb consistency and it just melts in your mouth. I decided to add fresh blueberries, and the sweet sour cream takes these bars to a whole different delicious level. These almost didn’t make it to the photoshoot, I was eating them like a starving pregnant woman! They were one of the best treats that I had had!

  1. These were pretty easy to make. My only criticism is that 3/4 cup of the crumbles wasn’t that much on top.

  2. Hi I would like to make these for a party but how far in advance can they be made and stored for ?? They look awesome , can’t wait to make them, THANKS for the recipe !!

  3. i made theses this past week for company and they were a hit! I used half raspberries and half blueberries, since I had both. Will definitely make these again. I cut them into 18 bars and found this to be a good serving size. 5 stars

  4. These are delicious! I added 1 tsp. lemon peel to the sour cream mixture. I also baked the crust at 350 degrees for about 15 minutes before adding the other ingredients. Thank you for this recipe!
