What Are Costco’s Lemon Blondie Bars?
Costco’s Lemon Blondie Bars are a fun twist on regular blondies. Instead of using chocolate chips, Costco adds a layer of bright yellow lemon filling in the middle. To balance out the sour lemon taste, they add a sweet drizzle of white chocolate on top.
The bakery uses real lemon juice, pulp, and peel. This gives the bars a real, fresh fruit flavor instead of a fake, sugary taste. The bottom layer stays soft and chewy, just like a good brownie or blondie should be. If you enjoy Costco’s bakery treats, you may also like exploring the Costco Food Court Menu for affordable pizzas, hot dogs, chicken bakes, and other popular favorites.
Price and Value
If you need to feed a crowd at a backyard BBQ or family gathering, this dessert is a great deal.
A box costs $8.99 and comes with 16 pre-cut bars. That means each bar costs only about $0.56. It is much cheaper than buying treats from a local bakery or making them from scratch at home.

Taste Test: How Do They Taste?
People who have tried them say the flavor combo is excellent. The bottom part is rich, buttery, and sweet. The middle lemon layer is sharp and sour, which cuts through the sweetness. The white chocolate on top adds a smooth, creamy finish. Because it uses real lemon, it tastes light and refreshing rather than heavy.
Fun Ways to Serve Them
These bars taste great right out of the box, but you can easily make them extra special with these simple ideas:
- Lemon Zest: Grate fresh lemon peel over the top for an extra pop of flavor.
- Strawberry Lemonade: Top the bars with fresh strawberry slices and a little strawberry syrup.
- Ice Cream Delight: Warm a bar in the microwave for 5 seconds and put a scoop of vanilla ice cream on top.
- Ice Cream Sandwiches: Cut the bars in half, put vanilla ice cream in the middle, and freeze them.
How to Find Them at Your Costco
Since this is a seasonal item, not every Costco will have them at the same time. They can also sell out fast.
Before you go, you can check the official Costco app or website to see if your local store has them in stock. You can also call your local store and ask the bakery department. If you see them on your next trip, grab a box before they disappear for the season!
