In the bowl of your stand mixer add the egg yolks, sugar, and salt. Using the paddle attachment, beat on medium speed until pale yellow and light and airy. About 4-5 minutes.
In a large pan heat the cream and milk over low heat, stir occasionally. If you have an instant read thermometer the mixture will reach 155-160°F. If you don’t have a thermometer, the mixture will be hot but not boiling!
Turn the mixer to low and add the heated cream in a slow, steady, stream. Mix until thoroughly combined, about 1-2 minutes. Pour the cream/egg mixture back into the pan and heat over medium-low heat stirring constantly. Heat to 155-160°F. If you don’t have a thermometer heat until it thickens and coats the back of a spoon. It should NOT boil, however, a few bubbles may come up along the edges. Remove from the heat and add the vanilla extract and 2 tsp ground cinnamon.
Set a fine mesh strainer over a large bowl. Pour the warm ice cream mixture into the bowl (through the fine mesh strainer). Cover and place the mixture in the refrigerator until completely chilled about 4 hours.
Once the ice cream mixture is cold, set up your ice cream machine according to the manufacturers directions. With the machine running, add the mixture in a slow steady stream. Churn according to the directions.
Once it’s done churning stir in the mini cinnamon chips. Transfer to a freezer-safe air-tight container and freeze until fully firm.
