Step 1: Mix the Batter Quickly - Grab your medium mixing bowl and crack in 2 large eggs, whisking them lightly until just combined. Pour in ½ cup granulated sugar and ¼ teaspoon salt, stirring until the mixture looks smooth. Slowly drizzle in ¼ cup melted unsalted butter, followed by ¼ cup whole milk and 1 teaspoon vanilla extract. Whisk everything together until uniform. Sift in 1 cup all-purpose flour gradually, folding it in with a spatula. Let the batter rest for 5 minutes.

Step 2: Cook the Waffle Circles - Heat a non-stick skillet over medium-low heat and lightly grease it. Pour about 2 tablespoons of batter into the center, spreading it into a thin circle. Cook for 2 to 3 minutes until edges look dry, then flip and cook for another 1 to 2 minutes. Remove and place on a wire cooling rack.

Step 3: Shape the Cones While Warm - Transfer a warm waffle circle to a clean surface. Roll it tightly around a cone-shaped mold, holding it in place for 15 to 20 seconds until it sets. Place the cone seam-side down on the cooling rack.

Step 4: Cool and Crisp Thoroughly - Leave the cones on the wire cooling rack for at least 30 minutes to cool completely. For extra crispness, place them in a preheated 200°F oven for 5 to 10 minutes.

Step 5: Store for Later Use - Store your waffle cones in an airtight container at room temperature for up to 5 days. Layer with parchment paper to prevent sticking.
