Heat-treat the flour: Spread the flour on a parchment-lined baking sheet. Bake at 350°F (175°C) for 6–8 minutes, stirring once, until it reaches 165°F throughout.
Let it cool completely so it doesn’t melt the butter. Alternatively, microwave in a bowl in 20–30 second bursts, stirring between each, until 165°F.
Cream the butter and sugars: In a mixing bowl, beat softened butter, brown sugar, and granulated sugar until light and fluffy, about 2 minutes. This helps your bites taste like real cookie dough.
Add the wet ingredients: Mix in milk, vanilla, and salt until smooth and creamy.
Add the flour: Sift or whisk the cooled, heat-treated flour to break up any lumps.
Add it to the bowl and mix on low until combined. The dough should be soft but not sticky. If too dry, add 1–2 teaspoons more milk.
If too sticky, add 1–2 teaspoons more flour.
Fold in the chips: Stir in the mini chocolate chips and any optional add-ins.
Chill briefly: Cover and refrigerate for 10–15 minutes to firm up. This makes rolling easier.
Roll into bites: Scoop tablespoon-sized portions and roll into balls. You should get about 18–22 bites.
Serve or store: Enjoy right away, or chill for 30 minutes for a firmer texture.
