👩🍳 Instructions
🍪 Make the Cookie Dough
1. Prepare the Oven
Preheat your oven to 350°F (175°C).
Line two baking sheets with parchment paper or silicone baking mats.
Set aside.
2. Cream the Butter and Sugar
Place the softened butter in a large mixing bowl.
Beat with an electric mixer for 3–4 minutes, until very pale, light, and fluffy.
Gradually add the sifted powdered sugar and continue beating for another 1–2 minutes.
The mixture should be smooth and airy.
3. Add the Vanilla
Add the vanilla extract and salt.
Beat briefly until incorporated.
4. Add the Dry Ingredients
In a separate bowl, whisk together the flour and cornstarch.
Gradually add the dry ingredients to the butter mixture.
Mix on low speed just until the flour disappears and a smooth, soft dough forms.
Do not overmix.
🌪️ Pipe the Viennese Whirls
5. Prepare the Piping Bag
Transfer the dough to a sturdy piping bag fitted with a large open star tip, such as a 1M-style tip.
The dough is thick, so use a strong piping bag.
6. Pipe the Cookies
Pipe approximately 3–4 cm (1¼–1½ inches) swirls onto the prepared baking sheets.
Hold the piping bag vertically and pipe a small circular swirl, finishing with a gentle flick of the tip.
Leave about 2 inches / 5 cm between each cookie.
Try to keep the cookies similar in size so they bake evenly.
7. Chill
Place the piped cookies in the refrigerator for approximately 15 minutes.
Chilling helps the butter firm up and allows the cookies to maintain their beautiful piped shape while baking.
8. Bake
Bake for 12–15 minutes, or until the edges are just beginning to turn lightly golden.
The cookies should remain relatively pale.
Don’t overbake them—their delicate texture is part of what makes Viennese whirls special.
9. Cool Completely
Remove the baking sheets from the oven.
Allow the cookies to cool on the trays for 5 minutes.
Carefully transfer them to a wire rack and allow them to cool completely before filling.
🧈 Make the Buttercream
10. Beat the Butter
Place the softened butter in a clean bowl.
Beat for 3–4 minutes, until pale and fluffy.
11. Add the Powdered Sugar
Gradually add the sifted powdered sugar while mixing on low speed.
Once incorporated, increase the speed and beat until smooth.
12. Add Vanilla and Cream
Add the vanilla extract and a pinch of salt.
Add 1 tablespoon of cream or milk and beat until light and creamy.
If the buttercream is too thick for piping, add another tablespoon of liquid a little at a time.
🍪 Assemble the Cookies
13. Fill the Cookies
Transfer the buttercream to a piping bag fitted with a small star tip.
Turn half of the cooled cookies upside down.
Pipe a small swirl of buttercream onto the flat side of each.
14. Sandwich
Place a second cookie on top of each filled cookie.
Press very gently so the buttercream reaches the edges without cracking the delicate biscuits.
Repeat with the remaining cookies.
🍫 Optional Chocolate Finish
15. Dip in Chocolate
Melt the chocolate gently in the microwave in short intervals or over a double boiler.
Dip one end of each assembled cookie into the melted chocolate.
Allow excess chocolate to drip off.
Place the cookies on parchment paper.
If desired, sprinkle the chocolate with chopped pistachios, nuts, or decorative sprinkles.
Allow the chocolate to set completely before serving.
⭐ Chef’s Tips
Use properly softened butter: Butter should be soft enough to beat easily but not melted or greasy.
Sift the powdered sugar: This helps create an exceptionally smooth dough and buttercream.
Don’t overmix: Once the flour is incorporated, stop mixing. Overworking the dough can make the cookies less tender.
Use a sturdy piping bag: Viennese whirl dough is thick and can be difficult to pipe through a flimsy bag.
Use a large star tip: A small piping tip makes the dough much harder to pipe.
Chill the piped cookies: This helps preserve the beautiful ridges and swirl pattern.
Keep them pale: These cookies should be delicate and lightly golden rather than deeply browned.
🍫 Easy Variations
Chocolate Viennese Whirls

Replace some of the buttercream with raspberry jam for a classic fruity filling.
Chocolate Buttercream
Add 2 tablespoons cocoa powder to the buttercream along with an extra tablespoon of cream.
Lemon Viennese Whirls
Add 1 teaspoon finely grated lemon zest to the cookie dough and a little lemon juice to the buttercream.
Pistachio Viennese Whirls
Add finely ground pistachios to the filling and finish the chocolate-dipped ends with chopped pistachios.

🧊 Storage
Store assembled Viennese Whirl Cookies in an airtight container at room temperature for up to 4–5 days.
Keep them away from heat and direct sunlight so the buttercream remains firm.
For the best texture, allow refrigerated cookies to sit at room temperature for about 15 minutes before serving.
❄️ Freezing
Unfilled baked cookies can be frozen for up to 2 months.
Place parchment between layers and store in an airtight freezer-safe container.
Thaw completely at room temperature before filling.
The assembled cookies can also be frozen, although the buttercream may become slightly softer after thawing.
