Ingredients:
- 1 sheet of puff pastry (thawed if frozen)
- 2 tablespoons unsalted butter, melted
- 1/4 cup granulated sugar
- 1 tablespoon ground cinnamon
- Optional: powdered sugar for dusting
- Optional: cream cheese or vanilla glaze for dipping
Required Equipment:
- Air fryer
- Rolling pin (optional, if you want to roll out the puff pastry)
- Heart-shaped cookie cutter (3-inch or preferred size)
- Baking sheet or parchment paper
- Small mixing bowl
- Pastry brush
- Measuring spoons and cups
Step-by-Step Instructions:
1. Prepare Your Puff Pastry
Remove the puff pastry sheet from the package and allow it to thaw completely if frozen. If desired, lightly flour a surface and roll out the dough with a rolling pin to smooth it and ensure an even thickness.
2. Mix Cinnamon Sugar Coating
In a small bowl, combine the granulated sugar with the ground cinnamon. Stir well to distribute the cinnamon evenly throughout the sugar.
3. Cut Out Heart Shapes
Using your heart-shaped cookie cutter, cut out hearts from the puff pastry sheet. Gently lift each heart and place it on a baking sheet lined with parchment paper. Re-roll remaining scraps of pastry to cut more hearts until the dough is used up.
4. Brush with Butter and Dust with Cinnamon Sugar
Using a pastry brush, lightly coat each heart with melted butter. Then generously sprinkle the cinnamon sugar mixture on top, ensuring every heart is nicely covered.
5. Air Fry the Hearts
Preheat your air fryer to 350°F (175°C). Arrange the hearts in a single layer in the air fryer basket without overlapping. Cook for 6–8 minutes, or until the hearts are puffed up and golden brown. For crispier hearts, you can flip them halfway through cooking.

6. Cool and Serve
Remove the cinnamon sugar hearts from the air fryer and let them cool slightly on a wire rack. Optionally, dust with powdered sugar for an extra touch of sweetness. Serve warm with cream cheese dip or vanilla glaze for an elegant finish.

FAQs
1. Can I use frozen puff pastry directly from the freezer in the air fryer?
It is best to fully thaw puff pastry before cutting and cooking. Frozen puff pastry is stiff and difficult to cut neatly, and it won’t puff evenly if cooked from frozen. For best results, thaw it in the refrigerator overnight or at room temperature for about 30-40 minutes until pliable.
2. How do I prevent the cinnamon sugar hearts from sticking to the air fryer basket?
Lightly grease the air fryer basket with spray oil or use parchment paper cut to fit the basket. Another option is using a silicone air fryer liner. These methods prevent sticking and make cleanup easier.
3. Can I make these hearts vegan?
Yes! Replace the butter with a plant-based margarine or oil such as coconut oil or olive oil. Be sure to check that the puff pastry you purchase is vegan-friendly, as some contain butter or milk products.
4. What’s the best dipping sauce to serve with cinnamon sugar hearts?
Popular dips include cream cheese frosting, vanilla glaze, or even chocolate sauce. These complement the sweet, cinnamon flavor nicely and add an extra indulgent touch for Valentine’s Day.
5. Can I prepare these ahead of time and reheat?
While air fryer Cinnamon Sugar Hearts are best enjoyed fresh and warm, you can store them in an airtight container at room temperature for up to two days. Reheat in the air fryer for 2-3 minutes at 350°F to regain crispness.
