Sour Cream Key Lime Pie Instructions

Making a Sour Cream Key Lime Pie is as easy as it is rewarding. Follow these simple steps, and you’ll be enjoying this delicious dessert in no time! Let’s dive in.
- First, preheat your oven to 350ºF. This is crucial for getting that perfect bake on your pie.
- Next, in a mixing bowl, whisk together the sweetened condensed milk, key lime zest, key lime juice, egg yolks, and sour cream. Make sure to mix well until fully incorporated and smooth.
- Once your mixture is ready, pour it into the prepared graham cracker crust. Spread it evenly, ensuring all areas are filled.
- Now, place the pie in the oven and bake for about 20 to 25 minutes. You want the filling to set slightly but remain creamy.
- After baking, remove the pie and allow it to cool at room temperature for a bit.
