salty sweet passionfruit crisp sandwiches
16 Mar 2026
When preparing last year's Christmas cookie box, I tried out 2 new recipes and both recipes failed. I couldn't use those cookies so this year I'm going to audition potential Christmas cookies in advance, hopefully avoiding the same situation.
I thought I'd make some passionfruit crisp sandwich cookies adapted from a recipe from Natalie Paull's book, Beatrix Bakes: Another Slice. The original recipe was for salty sweet lime crisp sandwiches but with a few passionfruit lurking in the crisper I decided to make a passionfruit version. The filling recipe is very generous and makes enough for 2 batches of cookies so the leftover filling is now in the freezer.
I cut the dough in half and placed one half back into the fridge. It's quite warm in Sydney at the moment and I found the dough softened very quickly making it almost impossible to handle. I managed to get about 10 cookies onto the tray but I needed to use a lot of bench flour in the process. Not wanting to admit defeat I pulled out a couple of sheets of baking paper and rolled out the rest of the dough between the 2 sheets of paper. This was so much easier and for the second batch of cookies, I just placed the piece of baking paper with cookies in situ onto a baking tray. I used a 6cm cutter to make the cookies because that's what I had in my kitchen and cut out a little peep hole in half the cookies, to expose the passionfruit filling.
Here's the recipe for you which makes 10-12 cookies. For all my recipes, I use a 250 ml cup and a 20 ml tablespoon. All eggs are 60 grams and my oven is a conventional oven not fan forced, so you may need to reduce your oven temperature by 20°C.
Salty sweet passionfruit crisp sandwiches – makes around 12 filled sandwiches
Lime cookies
100g unsalted butter
30g good extra virgin olive oil
zest of 1 lime or lemon
200g plain flour
1/4 tsp fine sea salt
1/2 tsp baking powder
1 egg
80g caster sugar
cooking oil spray
Sweet salty sprinkle
30g caster sugar
1/4 tsp sea salt flakes (lightly crushed)
Passionfruit frosting filling
30g passionfruit pulp
240g icing sugar
60g unsalted butter (very soft and squidgy)
15mls olive oil
1/4 tsp sea salt flakes
Lime Cookies
Melt the butter (microwave or stovetop), then add the oil and cool completely — warm butter will make a greasy, seized dough. Add the lime zest, then set aside to cool.
Weigh the flour, salt and baking powder together into a small bowl. Stir with a whisk to combine, then set aside. In a large bowl, hand whisk the egg and sugar energetically for around 30 seconds until it just turns a shade paler yellow. No need to whip in lots of air. Whisk in the cool butter/oil/zest. Switch to a stiff plastic spatula and stir in the dry ingredients until the mixture forms a thick, mashed potato–like paste and the bowl has clean sides. Scrape into a piece of plastic wrap and chill for a minimum of 3 hours, or ideally overnight, before rolling out.
Preheat the oven to 160°C, conventional. Line a shallow baking tray with cooking oil spray and baking paper. Give the dough, still wrapped, a few firm pushes against the work surface to encourage it to yield to the rolling pin. Unwrap the dough then roll out between 2 sheets of baking paper. Roll to around 30 cm × 30 cm (12 in × 12 in) — around 4 mm thick. Stamp out as many cookies as you can with a 6 cm fluted square cutter, making sure you stamp hard to cut through any zesty bits lurking along the cut lines. Lift the cut cookies onto the baking tray, only slightly apart, as they won’t spread at all.
Collect the scraps, squeeze together lightly and roll again. Try to avoid rolling a third time, but do it if you have to. No need to chill again — these can go straight in the oven to bake for about 40–50 minutes until firmly set (when you can easily lift one up). They should look dry, not gummy, and the colour will be a honey gold hue.
Remove from the oven, make the sweet salty sprinkle by mixing the sugar and salt in a small bowl and dust over the cookie tops while they are hot. Place the trays on a wire rack to cool completely for 10–15 minutes before filling, or cool in the oven overnight. If the oven temperature is any higher or you dust the raw dough with the sprinkle pre-bake, the cookies will start to contract and dome, making them a bit funny looking, and tricky to fill without overloading the curved space with excess frosting. If they are still warm, flatten with a heavy tray on top. The edges may crack a little.
Make the passionfruit filling while the cookies are baking and cooling. Place the passionfruit into the bowl of a stand mixer and add the remaining ingredients on top. Beat with the paddle attachment on speed 4 (below medium) for 10 minutes until the frosting is fluffy, pale and ultra-creamy. if the filling is looking a bit dry then add a squeeze or 3 of lime juice. Scrape the bowl sides down twice. The frosting should hold its shape and not be melty or slack. If the frosting does slump, take the bowl and paddle off the mixer and chill for 30 minutes. Return to the mixer and keep beating until cool and fluffy.
To fill the cookies, swipe a heaped teaspoonful of frosting on one cookie, smooth out evenly with an offset spatula, then swipe the spatula against the edges of the cookie to make a sharp finish. Sandwich the top on and give it a tiny squeeze together. Run your pinky finger around the sides to neaten up any oozy bits.
For cakeshop pro filling, scrape the frosting into a piping (icing) bag with a small sized tip (#3). Lay half the cookies, top side down, on a clean tea towel (dish towel) to prevent slipping. Pipe an outline of frosting, then fill it in. Sandwich the top cookie on.
Baked and filled the cookies will keep for up to 2 weeks, airtight and chilled. They soften a little over time.
They tasted as you would expect - a crisp biscuit that's equal part salty and sweet sandwiched together with a passionfruit cream filling.
Next week is Passover Week where I'll be sharing 5 Passover friendly bakes with you. I must get cracking though because I have 2 more bakes to prepare and photograph by next week.
See you all again next week.
Bye for now,
