1- Creating tiramisu brownies is straightforward and fun, perfect for home cooks and baking enthusiasts alike. Start by preheating your oven to 350°F (175°C) and prepare a 9×13-inch baking pan with butter and parchment paper for easy removal later.

2- In a small saucepan, melt the butter over low heat, then remove it from the heat and stir in the chopped chocolate until it’s fully melted. Let this mixture cool slightly before moving on. Meanwhile, sift the flour, espresso powder, and cocoa powder into a bowl and set it aside.

3- Next, in a medium bowl, beat the eggs, both sugars, salt, and vanilla on high speed until the mixture is thick and pale, which takes about 4-5 minutes. Gently fold the cooled chocolate-butter blend into this egg mixture. Then, add the sifted dry ingredients, mixing just until combined to keep the batter light.

4- Spread the batter evenly in your prepared pan and bake for 25 minutes, or until the top is lightly cracked and the center feels soft. After baking, transfer the pan to a wire rack and let it cool completely, about 30 minutes. For the espresso cream, combine mascarpone and heavy cream in a large bowl and beat on medium speed for about 30 seconds until smooth, then add sugar, salt, vanilla, and espresso powder, beating on high until soft peaks form, roughly 1-2 minutes.

5- Finally, spread the espresso cream over the cooled brownies and dust with 3 tablespoons of cocoa powder. Cut into 10 squares and serve for a decadent treat. If you’re adapting for dietary needs, incorporate vegan substitutes or gluten-free flour at the appropriate steps to maintain that wonderful texture and taste.
