Heat the passion fruit and sugar on a pot over medium heat

In a small bowl, combine the cornstarch and the water. If the mixture looks to stiff, add a bit more of water

Pour the cornstarch mixture into the passion fruit curd and mix using a wooden spoon.

Meanwhile, place the egg yolks in a bowl and whisk a bit

When the passion fruit mixture starts boiling and thickening, remove from the heat and gently pour 2-3 tablespoons over the yolks. Mix the yolks vigorously while you pour the hot liquid to prevent the yolks from cooking.

Place the yolk mixture into the remaining passion fruit curd and mix

Cover with plastic wrap and place in the fridge to completely cool

Preheat oven to 350 degrees Fahrenheit

Line a cookie sheet with parchment paper

Throw all the ingredients together in the bowl of a mixer and mix until combined

Make 1 tablespoon size balls and place them separately on the lined cookie sheet

With the back of a spoon or your thumb, make a deep indentation in the middle of the cookie being careful not to cut through the bottom

Spoon cooled curd in the middle

Bake for 10-12 minutes

Remove from oven

Let the cookies cool completely on a rack

Enjoy!
