Dessert Crackers with Custard and Blackberries

What happy things accidents can be! I've been trying to find an easy and 'perfect' way of baking little tart shells because I wanted to make Lucie's Buttertarts for Linda for her birthday. I still haven't succeeded in making the little shells (an ongoing project until I can crack the code, sans the troublesome pie weights), but one of the accidents in my attempts was that they just baked into flaky delicious disks. The following is what I made with them.

1 recipe Cookie Pie Crust

2 recipes Pastry Cream

80 to 90 blackberries

¼ cup chopped 70% dark chocolate

1. Start the Cookie Pie Crust to make the dessert cracker base.
2. While the dough is cooling, prepare the Pastry Cream up to step 5, then set aside.
3. When you've rolled out the dough, cut into disks - I use the top of a standard round plastic container, like a yoghurt container lid, for my cutting shape.
4. Arrange the disks on a large cookie sheet to blind bake, as per the instructions in the recipe, except lightly place a second cookie sheet on top. This will prevent the dough from puffing up excessively. Bake for 10 minutes, then remove the top cookie sheet and bake another 5 minutes or until the crackers start to lightly brown.
5. Allow the crackers to cool completely. 
6. Finish the Pastry Cream by following step 6 of the recipe which is to whisk in the heavy cream.
7. Assemble the crackers by evenly distributing the Pastry Cream in dollops onto the crackers; arrange the blackberries on top of the cream and lightly press into the cream.
8. In a double boiler melt the chocolate and drizzle lightly over the loaded crackers. 
9. You can either wait for the chocolate to set, or serve with the chocolate still semi-liquid. 
10. Have napkins at the ready - it's easy to get smeared with the chocolate!
