This creamy lemon impossible pie comes together with just one bowl and a blender delivering layers of lemony custard and tender crumb in a single swoop There is no fussing with pastry or water baths and as it bakes the batter magically settles into a luscious dessert that is equally at home at a spring brunch or weeknight treat
I love pulling this pie together with my daughter on lazy weekend mornings since the lemony scent fills the whole kitchen and reminds me of summers at my grandmother’s house
Ingredients
- Granulated sugar: brings sweetness and balances the tartness of the lemon using fine sugar helps it dissolve easily
- All purpose flour: gives gentle structure and you can swap with gluten free blends for allergies
- Unsalted butter: creates richness and tenderness in the custard so choose quality fresh butter
- Whole milk: adds creaminess though almond milk can work for a dairy free pie just keep it unsweetened
- Large eggs: bind everything and help form that signature custard texture fresh eggs add the best flavor
- Fresh lemon juice: ensures the pie tastes bright and lively use real lemons not the bottled kind
- Lemon zest: gives more aroma and extra tang always zest before juicing for the best fragrance
- Vanilla extract: adds warmth and rounds out the citrus so pick pure vanilla if possible
- Pinch of salt: lifts all the flavors and keeps sweetness in check
Instructions
- Preheat the Oven:
- Set your oven to three hundred fifty degrees Fahrenheit or one hundred seventy five degrees Celsius and give it at least ten minutes to really heat up This helps the pie cook evenly from the start
- Mix the Ingredients:
- Place the sugar flour melted butter milk eggs lemon juice lemon zest vanilla and a pinch of salt into a blender or large mixing bowl If using a blender blend until everything is completely smooth and pale yellow If by hand whisk well making sure the eggs and butter are fully incorporated and the flour is not lumpy
- Prepare the Pie Dish:
- Take a nine inch pie dish and lightly coat it all over with a bit of butter or nonstick spray This keeps the pie from sticking and makes slicing much easier later
- Pour and Bake:
- Pour the smooth lemony batter into your prepared pie dish set it right in the center of the preheated oven Bake for forty five to fifty minutes The top should turn a light golden brown and when you jiggle the dish the center should only wobble very slightly This is the key to knowing the custard is set
- Cool Down:
- Remove the pie from the oven Place on a rack and let cool for about thirty minutes It will continue to set as it cools so do not rush this step This makes slicing much cleaner
- Serve:
- Once cooled slice the pie into wedges Serve at room temperature for soft custard or refrigerate for a firmer pie Top with whipped cream or a light sprinkle of powdered sugar if you like

Lemon zest is my favorite ingredient as every time I grate it the whole kitchen fills with sunshine My daughter loves to help with the zesting too because she enjoys the bright yellow curls landing on the counter and it makes us laugh together every single time
