Mini Boston Cream Pie Recipe

In a medium bowl, combine the egg yolks, sugar, salt and cornstarch. Whisk them together until the mixture is smooth; set aside.
3 large egg yolks room temperature, 1/4 cup (50g) granulated sugar, 2 Tbsp (20g) cornstarch, tiny pinch of fine sea salt
In a medium saucepan, over low-medium heat, bring the milk to a simmer - just until you see steam coming out but not boiling - and then slowly stream the milk over the egg mixture, while whisking continuously.
1 cup (237mL) milk
Return the whole mixture to the pot and over low-medium heat, whisk continuously for a couple of minutes. After about 2ish minutes, you should feel the pastry cream thickening, at this point whisk aggressively and when it’s starting to stick to the pan, remove it from the heat (still whisking aggressively) and pour it into a bowl.
Add the butter and the vanilla bean paste, it may separate at first but then as you whisk the pastry cream with the butter and it will come together nice and smooth.
1/2 tsp vanilla bean paste or high quality vanilla extract, 3 Tbsp (42g) unsalted butter softened
Cover the surface with plastic wrap and allow it to cool to room temperature.

Bake the Athens Phyllo Shells at 400F (204C) for 5 minutes. While they're cooling, place the chocolate and coconut oil in a small bowl and microwave them for 15 seconds, 2-3 times, mixing in between, until the chocolate is smooth.
30 Athens Phyllo Shells, 1/2 cup (3oz) dark chocolate chips, 1 tsp coconut oil
Dip the shells, tops or bottoms, into the chocolate. Place them with the chocolate upright until they set.

For the chocolate ganache, use another small bowl to melt the chocolate with the cream in the microwave for 15 seconds, 2-3 times, mixing in between until it's smooth. Cover the chocolate and let it set until it's pipe-able.
1/2 cup (3oz) dark chocolate chips, 3 Tbsp heavy whipping cream

When the custard has cooled, use a piping bag, fitted with your favorite tip, (or a spoon) to fill the shells. Pipe some chocolate ganache on top and dust with cocoa powder and/or powdered sugar.
Dutch-process cocoa powder and/or powdered sugar for dusting
