Preheat oven to 180 and line 2 trays with baking paper.
In a medium sized bowl, sift flour, baking powder and salt and set aside.
In a large bowl, beat dairy-free spread with a handheld electric mixer until creamy. Add in vanilla and egg and continue beating until well combined. Add in sugar and beat through.
Add dry ingredients to the bowl and beat on low until the dough starts to come together, scraping down the sides of the bowl with a spatula as necessary. The dough will be quite soft. Depending on your climate you may wish to chill the dough for 20-30 minutes before baking to stop the cookies from overspreading in the oven.
Using lightly floured hands, roll tablespoons of dough into balls and place evenly on the trays allowing enough room between them to spread.
Using your thumb, press an intent into the top of the cookie ball pushing the edges out slightly. Fill the indent with ½ teaspoon of jam. Repeat will all cookies.
Bake in preheated oven for 13-15 minutes or until the edges are just starting to get a bit of colour. Let cool on the tray for 10 minutes to firm up before transfering to a wire rack to cool completely. Store cookies in an airtight container for up to 5 days.
