Method
Heat-treat the cookie dough flour
- Preheat the oven to 350F. Spread the all-purpose flour on a baking sheet in an even layer and bake for 5 minutes.
- Cool the heat-treated flour completely. Let the flour come to room temperature before using so the dough won’t melt.
Make and freeze the edible cookie dough chunks
- In a mixing bowl, combine the unsalted butter, brown sugar, milk, vanilla extract, and salt, mixing until smooth. Stir in the heat-treated flour and mini chocolate chips until the mixture becomes a cohesive dough.
- Roll the dough into small balls. Place them on a tray and freeze until solid so the chunks stay distinct in the ice cream.
Cook the vanilla custard and chill
- Warm the heavy cream and whole milk in a saucepan over medium heat until steaming. Whisk the warmed dairy into the egg yolks and granulated sugar that are beaten together.
- Cook the custard until it reaches 175F. Keep stirring constantly so it thickens without scrambling, then strain for a smooth base.
- Stir in the vanilla extract and salt. Cool the custard, then refrigerate for 4 hours.
Churn and freeze until firm
- Churn the chilled custard in an ice cream maker. In the last 5 minutes of churning, fold in the frozen cookie dough pieces.
- Transfer to a freezer-safe container and freeze until firm. Keep covered so the surface doesn’t dry out.
Notes
Pro tip: reach exactly 175F for a custard that thickens without turning grainy—if it starts to look curdled, remove from heat and strain immediately. Store in the freezer in a tightly sealed container for up to 2 weeks. Freeze the finished ice cream for best results; it will solidify well but may soften slightly after long freezer time. Dietary swap: use gluten-free 1:1 flour for heat-treating if you need a gluten-free cookie dough base (follow the same bake time).
