Frog’s Mouths Cookies – Žabí huby
Disclaimer: Frogs were not used to make this recipe. Haha. I thought I will put
that right at the beginning. These cookies can also have different names. Some
call them walnut clams or seashells. I really like the name frog mouths. They’re
called this because they go into the oven closed and some come out cracked
open, looking like a frog’s mouth.

Tips:
- I am using a small ravioli / dumpling maker to cut my round shapes and to
fill and close the cookies. If you don’t have one, just use the top of a glass to
cut out shapes (a wine glass works well). - If you roll the dough thinner you will have more cookies. However, don’t
make the dough too thin otherwise it could crack during baking.
Makes: About 55 frog mouths
Prep: 20 minutes
Hands On & Bake: 1 hour 20 minutes Bake: 340 °F (170 °C) 18 minutes
Coat with Sugar: 10 minutes
Total Time: 1 hour 50 minutes
Ingredients:
Dough
2 cups (280 g) all purpose flour, plus more for dusting
1⁄4 cup (30 g) powdered sugar
1 egg
2 tablespoons white vinegar
1 stick and 6 tablespoons (200 g) unsalted butter, at room temperature
Filling
1 1⁄2 cups (150 g) walnuts
1 1⁄4 cups (150 g) powdered sugar
2 egg whites (total 2.6 ounces / 70 g)
Coating
Powdered sugar
Directions:
- Into a bowl of a stand mixer add 2 cups all purpose flour and ¼ cup powdered
sugar and mix with a wooden spoon. - Add 1 egg, 2 Tbsp white vinegar and 1 stick and 6 Tbsp softened unsalted butter.
- Start mixing on slow in the stand mixer fitted with a dough hook attachment.
Add more speed after it is more incorporated. - Finish forming the solid ball of dough in your hands. Transfer the dough to a
plate, cover with plastic wrap and let rest in the refrigerator until filling is done. - Making the filling: Finely grind 1 ½ cups walnuts into a medium sized bowl.
Add 1 ¼ cups powdered sugar and mix with a wooden spoon. Add 2 egg
whites and mix well together until there are no more dry ingredients. - Prepare a baking sheet lined with parchment paper.
- Preheat oven to 340 °F.
- Dust a pastry board with flour.
- Cut off about ⅓ of the dough, and flatten it with a rolling pin into about
⅛ inch (3 mm) thickness. (Dust the board and rolling pin with flour
as needed.) - Cut out a round shape and put about 1 tsp of walnut filling into the center.
Fold in half, sealing the edges together. Don’t seal the edges too tightly,
otherwise none of the frog mouths will open. - Bake for about 18 minutes or until golden brown.
- Let them cool off.
- Prepare a bowl with a generous amount of powdered sugar.
- One at a time, fully submerge each cookie into the powdered sugar so that
the cookie is fully coated.



Loved the video! I will be making these this weekend in Ohio, USA. Thank you for sharing.
I hope you enjoy them Rose.
Why no cookbook for sale? My daughter would love one. I hoped to buy one for her for Christmas but no luck. Will There ever be one?
I am so sorry Toby! I was hoping to have it done before Christmas, but self publishing takes more than I expected. The book is written I just have to put it into AI and have print copy send to me. I am hoping in next few months. Thank you for your patience. Next books will be much easier since I will know exactly how everything works. I did bunch of research to have hardcover available and not spend fortune on it. I want the book to be perfect.
Yummy cookies, made half recipe and they turned out great! Enjoy your videos … keep up the good work!
Glad to hear Cindy!

Thank you Marie! Hope you enjoy them!
Thanks for your blog and especially for this recipe. The cookies look extremely delicious.
I found you some time ago when I was searching for a recipe for Golatschen. My bohemian grandmother used to make them and they are a very appreciated childhood memory to me. Thanks to you I can make them myself now (my mother never bothered to bake with yeast dough).
Please continue to post your czech recipes. Maybe some more childhood memories will appear.
Kind regards
Thank you Nat! I hope my recipes will bring back wonderful memories! :)
Do you have a recipe for kolachkes? My grandmother used to live in Cicero / Berwyn and bought them for us from a local bakery (on Cermak?) when we visited. I remember the kolachkes were relatively flat and dense, filled with fruit or cheese.
Yes just do search in my website for Kolache
These cookies look delicious. Where do you purchase the cutter that folds and what is it called?
Link is under the recipe on this page.
Hello. I see the link for the cutter but what is the size of the one you used? I don’t need to purchase all of them. Thank you! Can’t wait to make this
I use the smallest one. Which would be 2.5 inches.
Loved your video, I will have to try making these! They look delicious
Great recipe but the dough was breaking up (praskalo) malo masla nebo moc mouky?
To je mi lito. Pokud praska, tak je tam moc mouky.
Hello
I’m So glad I came across your page-I love all these reminders of cesko,especially your Lada pictures.We are living in Australia for the last 30 years but we were kids in Czechoslovakia.My mum works hard in the 30 degree heat to keep baking vanocni pecivo-it is a bit insane but it is in her system…so many types,my favourite being grilias-do you know that one?the delicious nutty caramel in between wafers…
I also have to contribute to this tradition and will make zabi huby-I’ve never heard of these but I think my parents will be impressed and will know them. Thank you so much for your site…a vesele vanoce
Thank you Sasa! Vesele Vanoce! :) Yes I have heard about grilias, but it is more common in Slovakia. I hope you enjoyed zabi huby. :)
Hi Kristyna!!
I did try this recipe but didn’t have the tool, so I used the glass.
Just wanted to ask where did you get the tool from. I was looking on Amazon and actually ordered something similar but it is too big!! Didn’t like it. Did you buy your tool in Czech republic or here in USA?
Thanks and Happy, Healthy and Successful New Year!!
Eva
P.S. The taste was good!!!!
Hi Eva, bellow the video I have a set from Amazon. I think I have the same ones. Should have the small one. Thank you :) Happy new year! I am glad you enjoyed them.
