Creating your Chocolate Strawberry Tart is straightforward if you follow these steps:

1. Make the Tart Crust:

• Preheat your oven to 350°F (175°C).
• In a large mixing bowl, combine flour, cocoa powder, and powdered sugar. Mix well.
• Add the cold, cubed butter to the bowl and rub it into the dry ingredients until the mixture resembles coarse crumbs.
• Add the egg yolk and mix until the dough begins to form. If the dough is too crumbly, add ice water one tablespoon at a time until it holds together.
• Press the dough evenly into a 9-inch tart pan, ensuring it covers the bottom and sides. Prick the bottom with a fork to prevent bubbling.

1. Bake the Tart Crust:

• Bake in the preheated oven for 15-20 minutes until set. Remove from the oven and let it cool completely.

1. Prepare the Chocolate Ganache:

• In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer.
• Remove from heat and pour over the chopped chocolate in a heat-safe bowl.
• Allow it to sit for a couple of minutes, then stir until smooth and glossy. Add the vanilla extract and mix well.

1. Assemble the Tart:

• Pour the chocolate ganache into the cooled tart crust, spreading it evenly with a spatula.
• Refrigerate for 30 minutes to set the ganache.

1. Decorate with Strawberries:

• Once the ganache is set, arrange the halved strawberries on top of the tart in a visually appealing way.
• Optional: Garnish with fresh mint leaves for an added touch.

1. Slice and Serve:

• Carefully slice the tart into wedges using a sharp knife. Serve with extra strawberries or a dollop of whipped cream if desired.
