Flaky puff pastry hearts filled with smooth Nutella create an irresistible treat. The buttery layers paired with chocolate hazelnut spread form adorable heart shapes perfect for special moments like anniversaries, Valentine's Day, or just because. I'll never forget making these for a quiet night in - the smell of baking pastry and warm chocolate spread throughout our home, setting the scene for a truly special evening.
I surprised my sweetheart with these treats last Valentine's Day alongside fresh coffee. The look on his face was priceless, and now he asks for them whenever we're celebrating something important.
Key Ingredients and Shopping Advice
- Puff Pastry: Grab it from the freezer section and let it thaw properly
- Nutella: Let it sit out a bit so it's easier to spread
- Egg: Creates that beautiful golden shine when baked
- Powdered Sugar: Not required but makes them look fancy
- Berries: They cut through the sweetness if you want to add them
Step-by-Step Baking Guide
- Get Everything Ready: Heat your oven to 375°F. Put parchment on a baking tray. Lay out your thawed (but still cool) puff pastry on a lightly floured counter.
- Make Your Hearts: Cut an even number of heart shapes using a cookie cutter or knife. Don't dawdle - cold pastry gives the best results.
- Quick Chill: Put your cut hearts on the baking sheet and stick them in the fridge for 10 minutes. This helps them keep their shape when baked.
- Fill 'Em Up: Take hearts from the fridge. Put about 1 tablespoon of Nutella in the middle of half your hearts, leaving space around the edges for sealing.
- Make Heart Sandwiches: Put the plain hearts on top of the Nutella-covered ones, lining up the edges. Press the sides with your fingers to start sealing.
- Lock In The Filling: Use a fork to press all around the edges, making a pretty pattern while making sure the Nutella can't escape.
- Shine Them Up: Mix egg with a tablespoon of water until smooth. Brush this mixture over the tops of your pastries.
- Bake Until Beautiful: Put them in the oven for 12-15 minutes until they're puffy and golden. Keep an eye on them after 10 minutes as they can burn fast.
- Let Them Rest: Take them out and let them sit on the baking sheet for 5 minutes, then move to a wire rack for another 5-10 minutes.
- Add Final Touches: Sprinkle with powdered sugar if you want. Serve while they're still a bit warm, maybe with berries or whipped cream.

I first tried these at a tiny bakery in Paris and couldn't wait to make them at home. The baker told me their secret was "taking your time with the dough" - rushing just won't work.
Sweet Family Moments
These chocolate-filled hearts have become our go-to treat for celebrating important family events over the years. I can still picture my daughter making them on her tenth birthday, her tiny fingers carefully pressing the edges of each heart. These days she's away at college but calls home for instructions whenever she wants to wow her friends or celebrate a birthday. It's amazing how such a simple treat has become a thread connecting our family stories across years and miles.

Tasty Year-Round Variations
The classic Nutella filling is fantastic, but these pastries can change with the seasons. During summer months, I love tossing in some fresh strawberry slices alongside the Nutella for extra juiciness. When fall comes around, I'll add thin apple slices with a dash of cinnamon mixed into the chocolate spread. Winter holidays call for crushed candy canes or a small dollop of marshmallow fluff for something festive. The pastry works as a blank canvas that you can dress up with whatever's freshest or most fitting for the occasion.
The Magic of Flaky Layers
Getting to know how puff pastry actually works has taken my results from decent to amazing. The trick happens because of all those thin layers of dough and butter that create steam in the oven, pushing everything apart. That's why keeping everything cold matters so much. Warm butter just soaks into the dough instead of making separate layers. I've found that putting the assembled hearts in the fridge for 15 minutes before baking makes them rise even higher and break apart with that perfect crackly texture when you bite into them.

Closing Thoughts
Making these Nutella hearts reminds me why baking brings me so much joy - turning basic ingredients into something that makes people smile. They've become my go-to treat that everyone asks for at family get-togethers, and I often drop them off to neighbors during the holidays. Their real magic isn't just how good they taste but how they bring folks together through shared moments of happiness. Whether you've been baking for years or just starting out, these treats hit that sweet spot of looking impressive while actually being pretty easy to make - definitely worth adding to your favorites list.
