Whisk the Wet Goodness: In a spacious bowl, effortlessly combine the melted (and now cool!) butter with both the brown and granulated sugars, plus the sea salt. Whisk by hand until everything is beautifully blended – no need for a fancy mixer here!
Stir in Vanilla & Egg: Add your vanilla extract and the single large egg. Give it a good whisk for about 45 seconds until the mixture gets a bit thicker and lighter in color. This simple step is your secret to wonderfully chewy cookies!
Fold in Dry & Chocolates: Gently sift the flour and baking soda right into the same bowl. Toss in most of your milk chocolate and mini chocolate chips, keeping a few tablespoons aside for that perfect top layer.
Mix Just Enough: Using a spatula, carefully fold the ingredients together. Stop as soon as you can no longer see dry streaks of flour. Overmixing is a no-no for tender cookies!
Shape into Lovely Hearts: Scoop the dough into 14 even balls and place them on a baking sheet lined with parchment paper. Using your fingers, gently flatten and shape each ball into a heart. Make them a bit long and narrow, as they'll naturally spread. Press your reserved chocolate chips onto the tops for extra charm!
Chill for Best Results: Place your shaped cookie hearts in the fridge for 1 hour, or speed things up with 25 minutes in the freezer. This quick chill is essential for great texture and helps prevent too much spreading.
Bake with Care: Preheat your oven to 355°F (180°C). Arrange the chilled hearts on a parchment-lined baking sheet, giving them plenty of space. Bake for just 7-9 minutes until the edges are lightly golden and the centers are still slightly soft – they'll continue to set as they cool.
Cool & Enjoy: Let the cookies cool on the baking sheet for a minute before gently moving them to a wire rack. These cookies are absolutely divine when enjoyed slightly warm. A simple, wholesome treat made with love!
