Just a Quick Note About the Recipe
For this recipe I used regular limes rather than key limes because key limes were difficult to find locally. The result is still vibrant and delicious—if you have key limes available, feel free to use them (you may need a few more to reach the same juice and zest amounts).
Suggested Baking Tools and Tips
Before you begin, here are a few helpful notes and equipment suggestions to make this recipe go smoothly.
- I used a 9″ pie plate for baking this pie; a similar sized dish will work fine.
- If Bahlsen Delice puff pastry twists aren’t available, you can substitute graham crackers for the crust—keep the quantities similar. Another option is to use any crisp, buttery cookie or pastry crumbs.
- If using true key limes, you may need more fruit to yield 1/2 cup lime juice and 2 teaspoons lime zest.
- Bake the crust 8–10 minutes at 350ºF; it should set and become lightly golden. Chill the crust if you prefer before adding the filling.
- Allow the pie to cool completely after baking, then refrigerate if not serving immediately. The pie keeps well in the refrigerator for about three days.

This Easy Key Lime Pie has a silky, tart filling baked inside a buttery puff-pastry-style crust and finished with fluffy homemade whipped cream—ideal for summer.
Ingredients
Pie crust
- 7 oz Bahlsen’s Delice Puff Pastry Twists (about 40 pretzels), processed into fine crumbs
- 1/8 cup granulated sugar
- 5 tbsp unsalted butter, melted
- 1 tsp vanilla extract
Key lime pie filling
- 4 large egg yolks
- 14 oz sweetened condensed milk
- 2 tsp lime zest
- 1/2 cup lime juice (about 3 medium regular limes)
Homemade whipped cream
- 1 1/2 cup heavy whipping cream
- 5–6 tbsp powdered sugar
- 1 1/2 tsp vanilla extract
Instructions
Pie Crust
- Adjust the oven rack to the second-from-center position and preheat the oven to 350ºF.
- In a food processor, pulse the puff pastry twists into fine crumbs. Add the sugar, melted butter, and vanilla and pulse until combined.
- Press the mixture into a 9″ pie plate, covering the bottom and sides evenly. Use the bottom of a measuring cup to level the crust.
- Bake the crust for 8–10 minutes, then remove and let cool. Chill if desired before adding the filling.
Key Lime Pie
- Keep the oven at 350ºF. In a mixer fitted with a whisk, beat the egg yolks on medium-high until thick and creamy.
- Lower the speed and add the sweetened condensed milk, mixing until combined.
- Return to medium-high speed and add the lime zest and lime juice. Beat until fully combined.
- Pour the filling into the prepared crust and bake 15–20 minutes at 350ºF, until the filling is set at the edges but still slightly jiggly in the center.
- Remove from the oven and let cool completely. Refrigerate if not serving right away.
- Top with homemade whipped cream and thin lime slices, if desired, before serving.
Homemade Whipped Cream
- For best results on hot or humid days, chill the mixing bowl and whisk for 15–20 minutes.
- In a stand mixer with a whisk, beat the heavy cream on high until stiff peaks form. Add powdered sugar and vanilla and whip until combined.
- Spoon or pipe the whipped cream over the pie just before serving.
Notes
- I used a 9″ pie plate for this recipe. A similar size works well.
- If Bahlsen Delice puff pastry twists are unavailable, graham crackers or another crisp cookie can be used for the crust; keep quantities similar.
- If you use true key limes, you may need more fruit to reach 1/2 cup juice and 2 tsp zest.
- The pie crust bakes nicely at 350ºF for about 10 minutes. Cool before filling.
- Let the baked pie cool completely, then refrigerate if not serving right away. It will keep about three days in the fridge.
