Tools

- 1 Bowl
- 1 Pan – non-stick – diameter 9.5 in
- 1 Saucepan
- 1 Plastic wrap
- 1 Baking dish
Steps
Preliminaries for the shortcrust in both versions.
Take the butter out of the fridge so it becomes soft like a pomade.
Preheat the oven to 356°F. Grease and flour a springform pan or line it with parchment paper with a removable base (Ø 9.5 in)
In a small saucepan heat the milk with the vanilla and both the instant and espresso coffee.
Meanwhile, elsewhere, beat the yolks and sugar with the whisk of an electric mixer or stand mixer until the mixture is pale and fluffy. Then add the cornstarch and mix a little more.
When the coffee milk begins to come to a simmer, gradually add the egg mixture, stir gently, and wait for the first bubbles to appear on the surface.
At this point remove the saucepan from the heat and whisk quickly. The custard will thicken immediately.
Transfer it to a wide, shallow baking dish, cover with plastic wrap directly on the surface and let it cool.
In a large bowl put 2 eggs, 9 tbsp butter, 2 3/4 cups all-purpose flour, 1/2 cup cocoa, 1/2 sachet baking powder, and 1 sachet vanillin, and mix avoiding compacting the dough; it should remain crumbly, not compact. To obtain this, gather the mixture between your hands and rub them against each other.
Transfer half of the crumbs to the bottom of the pan, spreading them evenly without pressing.
Spoon the coffee custard over the base, leaving the edge free, add the chocolate chips and cover with the remaining crumbs.
Bake in a hot oven for 25 – 30 minutes (356°F). Allow the crumb cake to cool before removing from the pan.
