How to Make Irresistible Molten Chocolate Lava Cookies

• Prepare Hot Fudge Sauce: Start by making your easy one-pot hot fudge sauce. Chill it with added cocoa powder for at least 4 hours until it’s set and ready to use.
• Cream Butter and Sugars: In a mixing bowl, combine softened salted butter with light brown sugar and granulated sugar. Beat together until the mixture becomes pale and fluffy, about 2-3 minutes.
• Incorporate Egg and Vanilla: Add the large egg and pure vanilla extract to the creamed butter mixture. Mix until fully combined, creating a smooth batter.
• Sift Dry Ingredients: In a separate bowl, sift together all-purpose flour, cocoa powder, baking soda, and salt. Gradually fold the dry ingredients into the wet mixture until just combined, then refrigerate for 2 hours to firm up.
• Form Fudge Centers: Roll chilled hot fudge sauce into small balls, then coat them in cocoa powder. Freeze these fudge balls for about 30 minutes to keep them firm.
• Assemble Cookies: Once your dough is chilled, scoop out portions and flatten them. Place a fudge ball in the center of each dough round, then wrap the dough around to fully encase the fudge. Chill for another 15 minutes.
• Bake: Preheat your oven to 375°F (190°C). Bake the cookies for 8-10 minutes until the edges are set but the centers are still soft. Allow them to cool on the baking sheet for a few minutes before transferring to a wire rack.
