Step 1: In a large mixing bowl, beat the softened unsalted butter with both granulated sugar and light brown sugar until the mixture is light, fluffy, and pale in color. This step is crucial for incorporating air, which contributes to the cookies’ tender texture. Don't rush it—beat for at least 3-4 minutes.
Step 2: Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Then, stir in the vanilla extract. Scrape down the sides of the bowl to ensure everything is well combined.
Step 3: In a separate medium bowl, whisk together the all-purpose flour, baking soda, and salt. Make sure there are no lumps.
Step 4: With the mixer on low speed, gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix, as this can lead to tough cookies.
Step 5: Gently fold in the chopped white chocolate chunks. I prefer chunks over chips as they melt more beautifully.
Step 6: Carefully fold in the fresh (or lightly floured frozen) raspberries. Handle them gently to avoid crushing them too much and turning your dough purple. You want distinct bursts of raspberry! This delicate balance is key to amazing White Chocolate Raspberry Cookies.
Step 7: Cover the bowl with plastic wrap and refrigerate the dough for at least 30 minutes, or up to 24 hours. Chilling helps to prevent the cookies from spreading too much, intensifies the flavors, and results in a thicker, chewier White Chocolate Raspberry Cookies.
Step 8: Preheat your oven to 375°F (190°C). Line baking sheets with parchment paper or silicone baking mats. This prevents sticking and ensures even baking.
Step 9: Use a cookie scoop (about 1.5 to 2 tablespoons) to drop rounded mounds of dough onto the prepared baking sheets, leaving about 2 inches between each cookie. Bake for 10-12 minutes, or until the edges are lightly golden and the centers are still slightly soft.
Step 10: Let the White Chocolate Raspberry Cookies cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely. This allows them to set up properly and prevents them from breaking.
