Baby Lemon Impossible Pies

These mini lemon custard pies are the perfect combination of sweet and tangy, with a smooth, creamy texture and a delicate golden top. As they bake, the ingredients separate into a soft, custard-like filling with a light, almost crust-like layer at the bottom—hence the name “impossible pie”! They’re incredibly easy to make, requiring only a handful of ingredients, and they come together in no time.

Each bite delivers a refreshing burst of citrus, making these baby lemon pies perfect for spring, summer, or any time you crave something light and zesty. Plus, they’re baked in a muffin tin, making them easy to serve, whether for a party, afternoon tea, or just as a little treat for yourself.

Ingredients

To make these delightful little lemon pies, you’ll need:

Wet Ingredients:

1 can (14 oz) sweetened condensed milk – Adds sweetness and a rich, creamy consistency.
½ cup fresh lemon juice – Provides a bright, tangy citrus flavor. Freshly squeezed is best!
Zest of 1 lemon – Enhances the flavor with an extra citrusy kick.
2 large eggs – Helps create the custard texture and binds everything together.
¼ cup unsalted butter, melted – Gives the pies a tender, buttery richness.
1 teaspoon vanilla extract – Adds a warm, sweet note that balances the tanginess.

Dry Ingredients:

½ cup self-rising flour – Helps the pies set and creates a slight crust-like layer.
Powdered sugar (for dusting) – Adds a light sweetness and decorative touch.

Step-by-Step Instructions

1. Prepare Your Baking Equipment

Preheat your oven to 350°F (180°C). Lightly grease a 12-cup muffin tin with butter or non-stick spray. You can also use silicone muffin molds or line the tin with cupcake liners for easier cleanup.

2. Mix the Batter

In a large mixing bowl, whisk together the sweetened condensed milk, fresh lemon juice, and eggs until smooth. The acidity of the lemon juice will slightly thicken the mixture.

Next, add the melted butter, vanilla extract, and lemon zest, stirring well to incorporate.

Finally, sift in the self-rising flour and gently whisk until fully combined. The batter will be thin and pourable, which is normal—it will firm up beautifully as it bakes.

3. Fill the Muffin Tin

Carefully pour the batter into each muffin cup, filling them about ¾ full. The pies will puff up slightly while baking, so leave a little room for expansion.

4. Bake Until Golden and Set

Place the muffin tin in the preheated oven and bake for 18–20 minutes. The tops should be lightly golden, and the pies should look set in the center.

To test doneness, insert a toothpick into the center—it should come out mostly clean with just a few moist crumbs.

5. Cool Completely

Allow the pies to cool in the muffin tin for 5–10 minutes, then gently remove them and transfer them to a wire rack to cool completely.

They will firm up as they cool, so don’t worry if they seem soft right out of the oven.

6. Dust with Powdered Sugar & Serve

Once fully cooled, sprinkle the tops with powdered sugar for a beautiful finishing touch. Serve as is, or pair with a dollop of whipped cream for an extra indulgence.

Storage & Serving Tips

How to Store:

Refrigerator: Store leftovers in an airtight container in the fridge for up to 5 days. The flavor develops even more as they sit, making them even tastier the next day!
Freezing: These pies freeze well! Place them in a single layer on a baking sheet to freeze for an hour, then transfer them to a zip-top freezer bag or airtight container. They will keep for up to 2 months.
To Serve from Frozen: Thaw at room temperature for 30 minutes or in the refrigerator overnight.

Best Ways to Enjoy:

Serve chilled for a refreshing summer treat.
Enjoy warm with a scoop of vanilla ice cream.
Add a spoonful of lemon curd on top for extra citrusy goodness.
Top with fresh berries (strawberries, raspberries, or blueberries).
Drizzle with a light glaze made of powdered sugar and lemon juice.

Variations & Additions

Want to switch things up? Here are some fun ways to customize this recipe:

Coconut Lemon Impossible Pies: Add ¼ cup shredded coconut to the batter for a tropical twist.
Berry Burst Pies: Fold in ¼ cup fresh or frozen blueberries for a fruity contrast.
Orange-Lemon Pies: Substitute half the lemon juice with fresh orange juice for a citrus blend.
Extra Tangy Pies: Increase the lemon zest to 2 lemons for a more intense citrus flavor.
Gluten-Free Version: Use ½ cup gluten-free self-rising flour instead.

Why Are They Called “Impossible Pies”?

The term “Impossible Pie” comes from the fact that the batter is liquid when mixed, but as it bakes, the ingredients magically separate into layers—a soft, custard-like filling with a light crust on the bottom. No pie crust needed, and no complicated steps!

This technique was popularized in the 1970s and 1980s when Bisquick introduced their famous “Impossible Pie” recipes. This version, however, is flour-based instead of using baking mix, resulting in a lighter, more delicate texture.
