Preparation Phase & Tools to Use

To make Impossible Lemon Pie, you won’t need any fancy gadgets. Here are the essential tools and why they matter:

• Blender: This is the hero of the recipe. It combines all ingredients smoothly and evenly, ensuring the custard sets just right.
• Pie Dish (9-inch): Glass or ceramic works best for even baking. The dish’s size helps the “impossible” crust form properly.
• Measuring Cups and Spoons: Accuracy is key to the custard’s consistency.
• Oven: Preheating your oven ensures the pie cooks evenly and forms the layered effect.
• Cooling Rack: Helps the pie cool gradually, preventing cracks or sinking.

Preparation Tips

Use room-temperature ingredients for a smoother blend—especially eggs and milk. Always grease the pie dish to help the custard release easily and maintain that layered texture. Fresh lemon juice offers a brighter flavor than bottled, and adding a bit of zest enhances that citrusy punch. Don’t over-blend; once the mixture looks smooth and combined, it’s ready to pour. Allow the pie to cool completely before slicing to ensure clean cuts and set layers.

Ingredients for this Impossible Lemon Pie

• 1 cup granulated sugar
• 1/2 cup Bisquick baking mix
• 4 large eggs (room temperature)
• 1/4 cup unsalted butter, melted
• 2 cups whole milk (room temperature)
• 1/4 cup freshly squeezed lemon juice
• 1 tablespoon lemon zest (from 1–2 lemons)
• 1 teaspoon pure vanilla extract
• 1/4 teaspoon salt
• Optional: powdered sugar for dusting or whipped cream for topping

Step 1: Prepare Your Workspace

Preheat your oven to 350°F (175°C). Lightly grease a 9-inch pie dish with butter or non-stick spray to ensure the pie releases cleanly after baking. Place the dish on a baking sheet to make transferring to and from the oven easier.

---

Step 2: Blend the Ingredients

In a blender, combine the sugar, Bisquick, eggs, melted butter, milk, lemon juice, lemon zest, vanilla extract, and salt. Blend on medium speed for 30–45 seconds until the mixture is completely smooth. Avoid over-blending to prevent incorporating too much air.

---

Step 3: Pour into the Pie Dish

Carefully pour the blended mixture into the greased pie dish. Let the mixture sit for 1–2 minutes to allow any bubbles to settle. You might notice the liquid is thin—this is normal and will firm up during baking.

---

Step 4: Bake the Pie

Place the pie (still on the baking sheet) into the preheated oven. Bake for 50 to 55 minutes, or until the center is set and the top is lightly golden. A knife inserted near the center should come out clean. Keep an eye on it during the last 10 minutes to avoid over-browning.

---

Step 5: Cool and Set

Remove the pie from the oven and transfer it to a cooling rack. Allow it to cool completely at room temperature, then refrigerate for at least 1 hour before serving. This helps the custard set and enhances the lemon flavor.

---

Step 6: Garnish and Serve

Before serving, dust with powdered sugar or top with a dollop of whipped cream. A few lemon slices or twists make a beautiful finishing touch. Serve chilled or at room temperature for best flavor.

Notes

Impossible Lemon Pie is a classic dessert where the magic happens right in the oven. As it bakes, the ingredients naturally separate to create a delicate crust, a creamy lemony custard center, and a golden top. It’s best served well-chilled, allowing all the textures to firm up and the flavors to fully develop. If you’re short on time, you can make it the night before and refrigerate overnight.

Watch Out for These Mistakes While Cooking

• Using cold ingredients: Cold eggs or milk can prevent the custard from setting evenly.
• Over-blending: Mixing for too long introduces excess air, which can lead to cracking or an uneven texture.
• Not greasing the pie dish: This makes it difficult to remove slices cleanly.
• Underbaking: If the pie is too wobbly in the center after 55 minutes, give it a few more minutes and check again.
• Cutting too soon: Allow the pie to cool and set properly to avoid a runny mess.

Storage Instructions

Store leftover Impossible Lemon Pie covered in the refrigerator for up to 4 days. For best results, place plastic wrap directly over the pie or use an airtight container. Freezing is not recommended, as it can cause the custard to break and lose its creamy texture. Always chill the pie completely before storing.

Frequently Asked Questions

What makes it an “impossible” pie?

It’s called impossible because it magically forms its own crust while baking without any layering or pre-baking steps.

Can I use bottled lemon juice instead of fresh?

Yes, but fresh lemon juice gives the best flavor and aroma. Bottled juice can sometimes taste flat or bitter.

Can I use gluten-free baking mix?

Yes, a gluten-free baking mix can be substituted for Bisquick. Make sure it’s an all-purpose blend with leavening agents.

What if I don’t have a blender?

You can whisk the ingredients by hand or use a food processor. Just make sure the batter is completely smooth before baking.

Is this pie supposed to jiggle when done?

A slight jiggle in the center is okay, but it should not slosh. The center should set as it cools.

How do I know when it’s fully baked?

Insert a knife near the center. If it comes out clean or with a few moist crumbs, it’s done.

Can I make this pie ahead of time?

Absolutely! It’s even better after it’s chilled for several hours or overnight.

Can I use another citrus instead of lemon?

Yes! Lime, orange, or even grapefruit juice work well. Just adjust the sugar to taste, as some citrus fruits are sweeter or more tart.
