These Blackberry Key Lime Tarts are the best bit-sized treats out there. They have an amazing puff pastry crust with an even better filling – they’re perfect for anytime you want a sweet treat or an easy appetizer.

This recipe is just like a key lime pie, but in puff pastry form. These tarts have such light and yummy flavors that pair so well together. From the delicious lime to the fresh blackberries, everything about the recipe is perfection.

The key lime filling is almost like a custard and it is a hit every time. I love this recipe because you can really eat it whenever. It works in the summer because of the fruit flavors, but you can also serve a recipe like this around the holidays. Who doesn’t love something that works all year round?

Ingredients Needed

  • Puff Pastry: I used Pepperidge Farms.
  • Line Curd: Make it homemade or buy it from the store.
  • Blackberries: Fresh blackberries are the best.

How to make Lime Tarts

  1. Bake puff pastry cups according to package directions (at 400°F for about 15-20 minutes, then press the center down with a wooden spoon). Let cool for 5 minutes.
  2. Fill with key lime filling and top with a fresh blackberry. Best if served the day they are made, but the lime curd can be made up to 3 days ahead of time and stored in the refrigerator.

Expert Tips

  • Make as few or as many of these as you want. The package of puff pastry comes with 24 cups, bake however many you need. One recipe of lime curd will make more than you need for an entire package.
  • If you have limes on hand, I like to add some lime zest on top!
  • These will get soggy over time so they’re best made and served the same day.

  1. Way to go and face your fears! I am right there with you, I’d have a major anxiety attack if I had to speak in front of a group. You look like you are rocking it though!! 🙂

  2. My backside made the Crazy for Crust website. I have arrived! Ha. You were an awesome hostess, Dorothy. Such a fun and delicious afternoon. I’ll take 37 of these tarts, please! 

  3. Good job on being a hostess, that takes a lot of guts to talk in front of a large group! I know I couldn’t do it. I love how easy and cute these tarts are and I bet they taste out of this world! And I am totally going to have to try a blackberry margarita 😉

  4. I totally hear you on the introvert thing, put me in a room full of people I don’t know and its enough to make me feel anxious! I commend you, looks like you were doing a great job! Definitely have to try lime and blackberry together, sounds so good!
