Method
Heat-treat the flour
- Spread the all-purpose flour on a sheet pan and bake at 350F for 5 minutes, then let it cool completely before using.
- Keep the cooled heat-treated flour ready so it won’t melt the dough when mixed.
Make and freeze the safe cookie dough chunks
- Mix softened unsalted butter with packed brown sugar, milk, vanilla extract, and salt until smooth.
- Stir in the heat-treated all-purpose flour and mini chocolate chips until a thick dough forms.
- Roll the dough into small balls, place on a tray, and freeze until solid.
Cook the vanilla custard base
- Heat the heavy cream and whole milk just until steaming.
- Whisk egg yolks with granulated sugar until smooth, then slowly whisk in the hot cream-milk mixture.
- Cook the custard while stirring until it reaches 175F, then strain for a silky texture.
- Stir in vanilla extract and salt, then cool to room temperature and refrigerate for 4 hours.
Churn and finish with dough pieces
- Churn the chilled custard in an ice cream maker according to the manufacturer instructions.
- Fold in the frozen cookie dough pieces during the last 5 minutes of churning so the chunks stay intact.
- Transfer to a container and freeze until firm.
Notes
Pro tip: fully cool the heat-treated flour before mixing so the cookie dough balls hold their shape, and chill the custard until very cold for smoother churning. Refrigerate leftover ice cream covered for up to 7 days; freeze up to 2 months for best texture (thaw 10 minutes before scooping). For a dairy-light swap, use lactose-free milk and lactose-free cream; the cookie-dough heat treatment step still makes it suitable to eat.
