Zia Lena’s Date Bars

These date bars come from our great aunt’s recipe book, and will surely be your next favorite. These soft cookie bars are filled with plump, chopped Medjool dates and ground walnuts, reliable for a Christmas cookie tray or a mid-day treat!
The Pittsburgh Cookie Table is one of our favorite regional traditions, and if you aren’t familiar – we are excited to introduce you! The roots of the tradition are a bit murky, but various lore has been written about in everything from The New York Times to local news outlets. Though it is still normal to have a cake at a wedding, here it is customary for the couple’s family and friends to bake from-scratch cookies. At the reception, they are all lined out for guests to eat throughout the evening. Even better, to-go boxes are often available, so you have plenty of treats to remember the couple by.
Years ago, we went to a wedding with a fabulous cookie table that featured date bars, which unlocked a childhood memory. Our great aunt, our Zia Lena, had a beautiful date bar cookie recipe that we loved every time we had eaten it and we wanted to try making it on our own. After multiple passes through handwritten family recipes and coming up empty, we had to call some relatives in Wisconsin to track this down. We love it so much, and we are happy to share it with you.
We have done plenty of cookie and dessert bar recipes over the years, many with a brownie or thick cake-like consistency. Alternatively, these are thinner, and their texture is like a soft biscotti. Each bite is soft and just spongey enough to bounce back. simple and packed with dates and walnuts, these are a rich alternative to other, more mainstream, cookie bars.
What kind of dates should we use?
Depending on where you live, there may be only a few kinds of dates available to you – or you may have so many you aren’t sure where to start! The time for date harvesting is autumn/winter, which is when you will find the freshest and/or larger quantities at the store. Thanks to that timing, the date bars are made for your holiday trays!
Many recipes call for Medjool dates and that is what we recommend for these. They have the reliable sweetness and texture for baking and are the easiest to find. However, any type of date will do!
Serving and storing date bars
We use a smaller pan so we can make nice even squares – but you can do whatever you like when you slice these up. We do prefer to dust with powdered sugar after they have cooled a bit, but are still warm enough to have the sugar stick and settle in.
In an air-tight container, you can store these at room temperature for up to 1 week, which makes them great for gifting. They can also be wrapped tightly with plastic wrap, and then inside of a storage bag or container, and put in the freezer for up to 1 month.


- Yield: 12 cookies
- Prep: 15 minutes
- Cook: 20 minutes
- Total: 35 minutes
Ingredients
- 3 cups ( 375 g ) all-purpose flour
- 4 teaspoons baking powder
- 1½ cups ( 300 g ) granulated sugar
- 2 tablespoons unsalted butter, melted
- 4 eggs, lightly beaten
- 4 tablespoons cold water
- 2 teaspoons vanilla extract
- 1 teaspoon salt
- 16 ounces ( 453.59 g ) pitted dates, finely chopped
- 1 cup ( 117 g ) walnuts, ground
Method
- Preheat oven to 350 degrees F. Lightly grease a 10x15-inch jelly roll pan.
- In a medium bowl, whisk together the flour and baking powder; set aside.
- Using an electric mixer on medium speed, beat together the sugar and butter, until combined (it will be crumbly). Add the eggs, water, vanilla extract and salt and beat until thoroughly combined, scraping the sides of the bowl as necessary. Reduce the mixer speed to low and gradually add the flour mixture. Use a rubber spatula to fold in the chopped dates and ground walnuts.
- Spread the batter in the prepared pan and bake for 20 to 25 minutes, or until a toothpick inserted into the center comes out clean. Allow to cool, cut into squares and dust. They can be dusted with powdered sugar, if desired. These cookies can be stored in an airtight container or covered tightly with plastic wrap, at room temperature for up to 1 week.
