Cream the Butter and Sugars: In a large mixing bowl, using an electric mixer (handheld or stand mixer with paddle attachment), beat the softened butter, granulated sugar, and brown sugar on medium speed until light and fluffy, about 2-3 minutes. Scrape down the sides of the bowl as needed to ensure everything is well combined.

Add Vanilla: Beat in the vanilla extract until fully incorporated, about 30 seconds. This infuses the base with a beautiful aroma.

Incorporate Dry Ingredients (Except Flour): To the creamed mixture, add the unsweetened cocoa powder and salt. Beat on low speed until just combined, being careful not to overmix, as cocoa powder can create a dusty cloud if mixed too vigorously.

Add the Flour (Heat Treatment Precaution): Now, for the flour. Before adding, it's crucial to heat treat the flour to make it safe for raw consumption. Spread the 1 cup of all-purpose flour onto a microwave-safe plate. Microwave on high for 30-60 seconds, stirring once in between, until it reaches an internal temperature of 160°F (71°C) as measured by an instant-read thermometer. Alternatively, you can bake it on a baking sheet at 300°F (150°C) for 5-7 minutes, stirring occasionally. Let it cool completely before proceeding. Once cooled, gradually add the heat-treated flour to the wet ingredients, beating on low speed until just combined.

Adjust Consistency with Milk: With the mixer on low, slowly drizzle in the milk, a tablespoon at a time, until the dip reaches your desired consistency. You want it thick enough to scoop but still easily dippable. You might not need all of the milk, or you might need a tiny bit more – adjust to your preference.

Fold in Chocolate Chips: Remove the bowl from the mixer. Using a rubber spatula, gently fold in the mini chocolate chips until evenly distributed throughout the Luscious Brownie Batter Dip.

Serve & Enjoy: Transfer the Luscious Brownie Batter Dip to a serving bowl. Serve immediately with your favorite dippers.
