Strawberry Cookie Bars (Tertiy Pirog)

Strawberry cookie bars (tertiy pirog) from @natashaskitchen

I love testing and eating new cookies. I especially love cookies made with any kind of fruit. These are called “Tertiy Pirog” meaning grated pastry since the final layer of the cookie bars is grated over the top. This recipe was shared with me in a comment on my blog by one of my readers. The recipe was left anonymously so if it was you and you’r reading this, thank you!! My hubby really liked these cookies. They will have you reaching for a tall glass of milk. Enjoy!

Ingredients for Tertiy Pirog:

1 stick (1/2 cup) butter, softened at room temp
1/2 cup granulated sugar
1 egg, room temp
1/2 tsp baking soda
1/2 tsp white vinegar
2 cups + 2 Tbsp all-purpose flour *measured correctly
1 cup jam or thick preserves (I used strawberry spread from Costco)
Powdered sugar for dusting, optional

Strawberry Cookie Bars

How to Make Strawberry Cookie Bars:

1. Using a stand mixer, cream together 1 stick of butter with 1/2 cup sugar and 1 egg.

2. Stir together 1/2 tsp baking soda with 1/2 tsp vinegar. Once it fizzes, pour over your batter and mix until well combined.

3. Blend in 2 cups + 2 Tbsp flour. P.S. I measured flour by fluffing it up with a spoon then spooning it into the measuring cup and scraping off the top for exact measurements.

4. Freeze 1/3 of the dough for 45 min to 1 hr. Place remaining 2/3 of dough onto a large sheet of parchment paper, sprinkle lightly with flour and roll into a 9×13″ rectangle. Transfer rolled dough with parchment paper onto a jelly roll pan (rimmed cookie sheet; I used a 10×15″). Cover rolled dough with plastic wrap and leave at room temp until remaining dough is ready for grating.

5. Spread 1 cup of strawberry preserves over the top (or your favorite preserves – pick one with a little bit of sour/tartness). Grate the frozen piece of dough evenly over the top of your preserves. Bake at 350 for 25 min or until top is golden. When cooled, dust with powdered sugar if desired and cut into square cookies.

    I made these today, but not sure why my dough turned out super sticky were I couldn’t even roll it. I had to put a bunch more flour and use my hands to form it. I did use a hand mixer maybe that’s why? Any idea? Reply

    • Natasha
      natashaskitchen
      August 25, 2017

      Hi Julie, it sounds like it might be a variance in how the flour was measured – or sometimes if you use a different kind of flour than American All-purpose flour, the amount called for would be different because different kinds of flours have varying amounts of gluten. I hope that helps! I don’t think it would have been the hand mixer – although I would suggest folding the flour in using a spatula if using a hand mixer to combine the butter/sugar/egg mixture. Reply

    I want to try this but I am wanting to make this with unbleached organic flour ? Have you tried it ? Reply

    • Natasha

      July 24, 2017

      Hi Kateryna, I think that would work fine 🙂 I have been using unbleached organic flour in pretty much all of my baking and I find it substitutes straight across in nearly every recipe without issues (sometimes when you are replacing Canadian flour, you need to add a little more American flour, but in this recipe, it doesn’t make a difference). Reply

    Already made these 2 days in a row! Made them the other night and they were gone pretty quickly, my 2 kids (who are super duper picky and won’t eat practically any cakes/cookies/jellos) loved them!! My husband (who is also picky) absolutely loved these. So I had to make them again last night, and this time made double the portion. They remind me of a cookie my mom used to make, but I think mom made them with a sweet cheese filling. Thanks Natasha! Reply

        I am doing the same pirog with margarine or butter for years. Always making double size and experimenting with different filings. Proportions are the same for butter or margarine. Hope this helps Reply

    One of my favorite recipe on ur site. I love it, super easy . I also break the extra dough that goes into the freezer into smaller ball makes it easier to freeze and I don’t have to waist time on waiting 4 them to freeze, they freeze much faster being split in to 3-4 smaller sizes . Thank u Natasha. Reply

    Hi natasha,
    Does this dough freeze well? Can I freeze the dough for several days ahead and make the bars the day I need from frozen dough, have you tried that?

    Thanks. Reply

      Hi Elena, I haven’t tried but I have frozen them temporarily to chill them faster and it worked fine, so I think it would work to freeze them, just cover with plastic wrap before putting them in the freezer. Reply

    Hey Natasha! I always want to try your baking recipes but your directions always request a stand mixer or bread maker… and I literally have a whisk, wooden spoon, and hand mixer.
    It would be nice if you could explain the creaming and egg fluffing processes without today’s modern kitchen aids.
    I have the same troubles with cooking shows…I have seldom been in kitchens with kitchen aids and stand mixers and dough hooks and whisk hooks and help it’s so confusing!!!
    Anyway Thankyou for all your recipies. My husband is russian and he has been much happier since finding your blog. Reply

    • Natasha

      HI Saadi, You can use a hand mixer for this, but you’ll want to switch to a spatula once you add in the flour since the dough will be too thick for an electric hand mixer. I hope that helps 🙂 Reply

    Thanks for your super quick response! I baked the cookies tonight and I have to be honest they aren’t my favorite recipe and I didn’t get any oohs or aahs from my husband who has a tremendous sweet tooth for cookies and loves just about any kind! I used apricot preserves and nuts but I felt like it needs something else, maybe cinnamon or vanilla in the dough. Not sure if I will make them again. Reply

    Hi Natasha, this recipe looks great and I plan to try it in the next couple of days. Have you tried to press the bottom dough into the rimmed ccokie sheet instead of rolling it out? I do that for a shortbread recipe that I make and Its easy to do, I’m also going to make your Strawberry Layer Cake this weekend for my mom’s bday, it looks fantastic and I love your decorations! Thanks!! Reply

    i made these with raspberry preserves today. i just had trouble grating the dough. i kept it in the freezer for a little over a hour. but by the time i finished grating it, it was defrosting and sticking together. so i had to roll it all out and cut little pieces out of it. phew. but it still turned out amazing! love these! Reply

      It might take longer depending on if you shaped it into a little log or kept it in a ball and depending on where you put it into the freezer. It helps to use an oven glove to keep your hands off the dough so it doesn’t soften as quickly. I’m so glad you liked the cookies though 🙂 Reply

    Is the consistency of this dough like shortbread? It looks like a really tasty recipe, but I’m not a fan of shortbread. 🙂 So I’m trying to see if it’s worth trying or not. 🙂 Reply

  • Natasha
    September 7, 2014

    I’m making something similar, perhabs very similar, but twice as much dough at once. The only thing I do differently is I divide dough into 4 pieces and freeze all of them. Then I grate two for the bottom, spread the jam, and grate remaining two for the top. You will love the texture of the cookies when it’s all been grated! Looks pretty cool too! The reason I divide it into 4 portions is for the dough not to get too soft too early while you work with it.
    Love your pictures, amazing job, Natasha!! Reply
