Preheat: Set your oven to 350°F (175°C) and grease a 9x13-inch baking dish.

Make the Base: In a mixing bowl, cream together the butter and sugar until light and fluffy. Add the eggs one at a time, mixing well after each addition, and then stir in the vanilla extract.

Combine Dry Ingredients: In another bowl, whisk together the flour, cocoa powder, salt, and baking powder. Gradually incorporate the dry mixture into the wet batter until well combined. Fold in the chocolate sparks for an extra chocolatey treat!

Bake: Pour the batter into the prepared baking dish and bake for about 25-30 minutes. The cake is ready when a toothpick inserted comes out with moist crumbs. Allow it to cool completely.

Prepare the Ganache: Heat the heavy cream in a saucepan until it just begins to boil. Pour it over the chopped chocolate in a separate bowl. Let it sit for a minute, then stir until smooth and shiny.

Decorate: Once the cake has cooled, pour the ganache over the top and use a spatula to spread it evenly. Let it sit for an hour to set, or cool for 30 minutes for a quicker treat that’s still delicious!

Serve: Cut into squares and serve with a scoop of ice cream or whipped cream for added delight!
