Ingredients

Original recipe (1X) yields 8 servings

  • 2 cups milk

  • ¾ cup white sugar

  • 5 tablespoons all-purpose flour

  • ¼ teaspoon salt

  • 2 large eggs

  • 1 teaspoon vanilla extract

Directions

  1. Pour milk into a microwave-safe glass or ceramic bowl. Cook in the microwave on high until hot but not boiling, 2 to 4 minutes.

  2. Combine sugar, flour, and salt in a second microwave-safe glass or ceramic bowl. Whisk in hot milk gradually until incorporated. Cook in the microwave on high in 1-minute intervals, stirring after each interval, until thickened, 4 to 5 minutes.

  3. Whisk eggs in a medium bowl until pale and frothy. Whisk 1/3 cup milk mixture into eggs gradually, then whisk egg mixture into remaining milk mixture until smooth. Cook in the microwave on high until custard is thickened, about 2 minutes. Allow to cool slightly.

  4. Stir vanilla into custard until incorporated. Cool completely in the refrigerator before using, about 30 minutes.
