Baby Lemon Impossible Pies
Baby Lemon Impossible Pies — A Vintage Dessert That Melts in Your Mouth
There are desserts that feel nostalgic even before you take your first bite — the kind your grandparents might have made without a recipe card, simply because it was what everyone expected after Sunday dinner or potluck gatherings. Baby Lemon Impossible Pies are one of those timeless treats: easy to make, bright in flavor, and impossibly light.
The word “impossible” doesn’t mean tricky — it refers to how this pie transforms in the oven: the layers separate on their own into a smooth custard base with a tender cake-like top, all without being poured in stages. Add a citrus twist with fresh lemon, and you’ve got a dessert that feels both homey and delightfully refreshing.
Whether you’re baking for family, friends, or just treating yourself, these mini lemon pies bring comfort and sunshine to the table.
Baby Lemon Impossible Pies
Ingredients
-
1 box yellow cake mix
-
1 can (14 oz) sweetened condensed milk
-
½ cup sour cream
-
½ cup lemon juice (freshly squeezed)
-
1–2 tsp lemon zest
-
3 large eggs
-
Optional: powdered sugar for dusting or whipped cream for serving
Instructions
1) Preheat & Prep
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish (or use individual pie plates / ramekins if you want personal pies).
2) Mix the Batter
-
In a large bowl, whisk the cake mix, sweetened condensed milk, sour cream, lemon juice, lemon zest, and eggs until smooth.
-
The batter will be somewhat thick — that’s expected.
3) Bake
-
Pour the batter into the prepared pan.
-
Bake uncovered for 35–45 minutes, or until the edges are set and the center jiggles very slightly.
-
A toothpick in the center should come out mostly clean with a few moist crumbs.
4) Cool & Serve
Let the pies cool on a rack, then refrigerate for at least 2 hours so the custard can fully set. Dust with powdered sugar or add a dollop of whipped cream just before serving.

FAQ – Baby Lemon Impossible Pies
Q: Why is it called “impossible” pie?
Because the batter naturally separates in the oven into a custard layer underneath and a cake layer on top — almost like magic.
Q: Can I make these as individual pies?
Yes! Use greased ramekins and reduce baking time to 25–30 minutes.
Q: Why is the center still jiggly before cooling?
This dessert continues to set as it cools. A slight jiggle means it’ll finish perfectly once chilled.
Q: Can I make it less sweet?
You can reduce the sugar dusting or top with unsweetened whipped cream to balance sweetness.
Q: How long do these keep?
Store covered in the fridge for 3–4 days.
Q: Can I freeze this?
Yes — wrap individual portions and freeze up to 2 months. Thaw in the fridge before serving.
