British Jammy Dodger Biscuits

Instructions

1. Step 1

   Place the flour, sugar, salt, and baking powder into the bowl of a food processor. Chop the cold butter into small pieces and add to the processor. Pulse several times until the mixture resembles fine sand.

2. Step 2

   Lightly whisk the cream with the egg, egg yolk, and vanilla seeds. With the food processor running, slowly pour the egg and cream mixture through the top funnel. Stop as soon as the mixture comes together.

3. Step 3

   Tip the dough onto a lightly floured worktop and gently bring it together into a ball.

4. Step 4

   Wrap the pastry in plastic wrap and let it rest in the fridge for at least 30 minutes or up to 24 hours. 

5. Step 5

   Before cooking, heat the oven to 325 F (160 C).

6. Step 6

   Once the dough has rested, take it from the fridge and let it come to room temperature (about 15 minutes). 

7. Step 7

   Heavily dust the work surface with plain (all-purpose flour). Roll out the dough to 1/4-inch thickness (1/2 centimeter).

8. Step 8

   Using a 2-inch (5-centimeter) plain or fluted cookie cutter, cut as many biscuits as possible, you should be able to make at least 2 dozen.

9. Step 9

   On half of the biscuits, cut out a small 1/4-inch hole (1/2-centimeter) hole from the center. 

10. Step 10

    Lay the biscuits both with and without holes onto a baking tray lined with greaseproof paper or baking parchment (you may need to do this in batches depending on the size of your tray). 

11. Step 11

    Cook in the preheated oven for 10 to 12 minutes until lightly golden.

12. Step 12

    Remove from the oven and leave to cool completely. 

13. Step 13

    Place a small dollop of the jam onto each biscuit base and spread to within 1/4 inch (1/2 centimeter) of the edge of the biscuit. Make sure the jam creates an even layer on the biscuit. If you put too much, it will spill out, and if you use too little, the biscuits layers will stick together. 

14. Step 14

    Put the top biscuit layer on top and give it a little tiny twist, this will to help spread out the jam. 

15. Step 15

    Put the biscuits back on the tray and return to the oven for 5 minutes to cook the jam a little. 

16. Step 16

    Once more, remove from the oven and let it cool. Sprinkle with icing sugar (powdered or confectioners' sugar) before serving. Eat as soon as possible or store in an airtight tin or plastic container.
