In a bowl, whisk together flour, cocoa powder, and sugar.
Add eggs, milk, and vanilla extract. Whisk until smooth.
Stir in melted butter. Let the batter rest for 10 minutes.
Heat a nonstick skillet over medium heat and brush with butter.
Pour a small amount of batter into the pan and swirl to coat.
Cook for 1–2 minutes until the edges lift. Flip and cook the other side.
Repeat with remaining batter.
Fill each crepe with whipped cream and berries.
Fold or roll, drizzle with chocolate sauce, and dust with powdered sugar.
Serve immediately and enjoy!
