Sour Cream Zucchini Bars with Lemon Cream Cheese Frosting

Y'all, do you know the trick of using sour cream for baking?

I sure didn't until I was watching my mother in law making up a batch of pancakes, but instead of using water she used sour cream.

Say what??

In no uncertain terms, she told me to use sour cream in your baking for more flavor and richness. Yes, ma'am.

I have listened to her for 20 years and use sour cream everywhere I can in my cakes, cookies, breads, pancakes, and zucchini bars.

These zucchini bars use Kemps® Sour Cream to pack in more flavor, moisture, and richness to each bite. Kemps is 100% family farmer-owned and has the perfect texture and taste to make your taste buds do a happy dance when they take a bite!

In fact, I do this so often that Nate can head to Cub Foods, walk right to the Kemps sour cream (in the fridge in the back and middle of the store--if you ever use the Stillwater, MN location :)), and be back out the door in minutes. It's a handy dandy skill, he has. I’ll just have to make sure that he remembers to take advantage of THIS coupon offer saving me $1 on 2 Kemps Sour Cream products!

Side note that I think is cool...Y'all know that I live in Stillwater, MN. I love this town! Cub Foods began here in Stillwater, MN and has its headquarters about ¼ mile from my house. I'm a geek about that :).

If you have a food processor, use it to process your zucchini into small bits rather than using the shredder. So handy!

You don't need to press out the liquid, I've taken that liquid into account for this recipe. Just throw it in!

Cream cheese frosting is a classic pairing for zucchini bars. But have you tried lemon cream cheese frosting paired with them?

So good.

The zesty, lemon-y, cream cheese frosting is the BEST with these zucchini bars. The ultimate. All you need to do is add a bit of lemon juice and zest to amp up the flavor. I mean, so good!

  1. The ingredients list 1 1/2 tsp of baking soda, but directions say to stir in baking powder. I am not a good Baker, so I need some help on which to use. Thanks

    1. Oh gosh, that is on us. We should have these recipes super clear and easy to follow. It is baking powder that you use. Good luck!

  2. 5 stars
    Delicious! Even my adult daughter who originally made a face when she saw that zucchini was an ingredient, loved it and asked for several slices to take home with her. The lemon cream cheese frosting is perfect and delicious.

    1. Isn't that lemon frosting creamy and bright. Thanks for coming back and leaving a great comment, I appreciate it!
