Makes about 1 ⅓ cups

PREP TIME: 5 minutes
COOKING TIME: 1 to 1 ½ hours

INGREDIENTS

• 2 cups whole milk
• 1 ½ cups granulated sugar
• 2 tsp vanilla extract
• ¼ tsp cornstarch
• ¼ tsp baking soda

INSTRUCTIONS

1. In a large, heavy-bottomed saucepan, whisk together all of the ingredients. Bring to a boil over medium heat, whisking constantly.
2. Hook a candy thermometer over the side of the saucepan. Turn down the heat to low so the milk mixture boils gently. Cook, stirring occasionally, until it’s a deep caramel colour and very thick, and the candy thermometer registers 225ºF, 1 to 1 ½ hours. If the dulce de leche starts to catch on the bottom of the saucepan and looks like it might scorch, turn down the heat a little more.
3. Remove from the heat and let cool to room temperature.
