The other day, Fran watched Biscuit Week on the GBBO (I had fallen asleep on the couch) and decided Mary Berry’s Viennese Whirls might be a good next bake for me; I made them this morning and will take them to Daniel and France’s house to day for our day-after Father’s Day dinner.

These resemble shortbread cookies/biscuits with raspberry jam and buttercream filling. The cookie should be firm enough to handle, but soft enough to melt in your mouth with each bite. The trick is to adjust the viscosity of the dough to allow it to be piped into 2″ diameter circles using a star tip. To accentuate the whirl shape and texture, chill the piped biscuits in the refrigerator for 15 minutes before baking. (I didn’t do this and they lost some height and swirl detail.)
I was also making some raspberry jam, so I just sieved some to use for the cookies. I also added some meringue powder to help the buttercream harden a little to make the filling a little firmer without having to keep them refrigerated.

INGREDIENTS
For the jam
- 200g (7oz) raspberries
- 250g (9oz) jam sugar
For the biscuits
- 250g (9oz) very soft unsalted butter
- 50g (1¾oz) icing sugar
- 225g (8oz) plain flour
- 25g (1oz) cornstarch
For the filling
- 100g (3½oz) unsalted butter, softened
- 200g (7oz) icing sugar, plus extra for dusting
- ½ tsp vanilla extract
- 1 Tbl Meringue Powder
METHOD
For the jam,
- Put the washed raspberries in a small, deep-sided saucepan and crush them using a potato masher. Add the sugar and bring to boil over a low heat. When the sugar is melted, increase the heat and boil further for 4 minutes. Remove from the heat and carefully pour into a shallow container (pass it through a sieve if you’d rather not have seeds in your jam). Leave to cool and set.
For the biscuits,
- Preheat the oven to 375F. Line 3 baking sheets with non-stick baking parchment. Using a 2″ round cutter as a guide, draw circles on each sheet of paper, spaced well apart. Turn the paper over so the pencil marks are underneath.
- Measure the butter and icing sugar into a bowl and beat until pale and fluffy. Sift in the flour and cornstarch and beat well, until thoroughly mixed. Spoon the mixture into a piping bag fitted with a medium star nozzle. Pipe 24 swirled rounds (not rosettes), inside the circles on the baking sheets.
- Bake in the center of the oven for 13—15 minutes, until a pale golden-brown. Cool on the baking sheets for 5 minutes then carefully transfer to a wire rack to cool completely and harden.
For the filling,
- measure the butter into a bowl and sift the icing sugar on top.
- Add the vanilla extract and beat with a wooden spoon or an electric whisk until very light and smooth.
- Spoon into a piping bag fitted with a large star nozzle.
Spoon a little jam onto the flat side of 12 of the biscuits and place jam-side up on a cooling rack. Pipe the buttercream over the jam and sandwich with the remaining biscuits. Dust with icing sugar to finish.
Tips/Techniques
For this recipe you will need a piping bag, a medium star nozzle, a large star nozzle, 3 baking sheets. If your kitchen is warm and you have time you could try placing the whirls in the fridge for 15 minutes before baking. This will help them hold their shape while cooking.
be a good combination. The slight snap of this buttery cookie and the sweet/tartness of the fig pureé should pair well.
99.9% pure Tori. I added another filling to Tori’s fig and caramel apple, when Fran found a cannoli-chocolate chip filling. Talk about a cultural melting pot!
night I thought it appropriate to have some Chinese desserts. I saw both fortune cookies (ok not a dessert per se, but usually served after the meal) and black sesame macarons on the cooking shows we regularly watch.
this post, intending to document it the next time I make them. I found black sesame seeds at a specialty market near home and ground them to make a coarse powder. This gave the macaron a different texture than simply using fine almond powder.
adding the egg white. Second, she didn’t say when to add the black food coloring, so I added it after mixing the hot sugar mixture to the soft peak egg white and lastly I didn’t have any champagne so I just skipped it. The honey butter cream was awesome anyway.
these with two different fillings,
off the walls with a sugar high, let’s coat them with sugar icing! There is no thought of balancing flavors or textures here, just sweet and crunch. I saw a hint somewhere of using squeeze bottles with medium fine tips rather than traditional piping bags to decorate cookies. At about $1 each, what go wrong? As it turned out, they worked great and provided
more fine motor control than piping.
pipe thick icing. #1, it plugs the tip and “b” it takes a lot force (read: tired and cramping fingers and hands here). Once the damn dam is dried flood the inside with thinner frosting. Poke any holes with a toothpick. Let dry, probably overnight.
I love black and white cookies and I wish I could make them, oh wait, I did make them. I like to eat the white side first and save the chocolate side for dessert dessert.
