  • 2 large eggs
  • 2 cups milk ( I used 2%)
  • 1/2 cup sugar
  • 2 tbsp corn starch
  • 1/2 tsp Young Living Lime Vitality EO (or lime extract)


  1. Add the 1 1/2 cups of milk to a medium size sauce pan.

  2. Then add the sugar to the pot and mix.

  3. In a large measuring cup add the remaining 1/2 cup of milk, the corn starch. Mix really well until the corn starch is dissolved and there are no lumps. Then add in the eggs and the Young Living Lime Vitality EO. Mix again until combined.

  4. Turn stove on to medium heat and start stirring in your corn starch slurry.

  5. Continue to mix until mixture comes to a boil.

  6. Then pour into your mason jars or glass bowls. We garnished our custard with whipped topping and crushed graham cracker crumbs for a truly Key Lime pie feel. Serve warm or keep in the fridge for covered for up to a week.

Recipe Notes

To make a chocolate orange infused custard: Just add 2 TBSP of cocoa powder and Young Living’s Orange Vitality Essential Oil instead of lime extract.
