(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
Directions
Prepare the Cookie Dough: In a medium bowl, whisk together the flour, baking powder, and salt.
Cream Butter and Sugar: In a large mixing bowl, beat the softened butter and sugar together until light and fluffy. Add the egg and vanilla extract, mixing until fully combined.
Combine Wet and Dry Ingredients: Gradually add the dry ingredients to the wet mixture, mixing until a dough forms.
Chill the Dough: Divide the dough into two portions, wrap in plastic wrap, and chill in the refrigerator for at least 1 hour.
Preheat the Oven: Preheat the oven to 350°F (175°C) and line baking sheets with parchment paper.
Roll Out the Dough: Roll out the chilled dough to about ¼-inch thickness on a floured surface. Use heart-shaped cookie cutters to cut out the shapes.
Bake the Cookies: Transfer the heart-shaped dough to the prepared baking sheets and bake for 10-12 minutes or until the edges are lightly golden. Let the cookies cool completely.
Prepare the Marshmallow Fluff Filling: In a mixing bowl, beat together the marshmallow fluff, softened butter, powdered sugar, and vanilla extract until smooth and fluffy. If desired, add food coloring to customize the filling’s color.
Assemble the Cookies: Spread or pipe the marshmallow filling onto the flat side of half of the cookies. Top with the remaining cookies to form sandwich cookies.
Decorate: Use colored icing or edible markers to write fun conversation heart messages like “Be Mine,” “Love You,” or “XOXO.”

Variations
Flavor Twist: Add a teaspoon of almond extract to the cookie dough for a hint of almond flavor.
Fluffy Frosting: If marshmallow fluff isn’t your thing, swap it out for a simple buttercream frosting for a different texture.
Colorful Fun: Instead of the usual white marshmallow filling, you can tint it with different colors of food coloring to match any holiday or event.
Gluten-Free: For a gluten-free version, substitute the all-purpose flour with a gluten-free flour blend.
Storage/Reheating
To store, I recommend keeping the cookies in an airtight container at room temperature for up to 3 days. If you want them to last longer, you can refrigerate them for up to 1 week. If you’d like to enjoy them warm, you can briefly microwave them for 5-10 seconds.
FAQs
How can I make these cookies ahead of time?
You can prepare the cookie dough and freeze it for up to 3 months. Simply roll the dough into balls, freeze them on a baking sheet, and then transfer them to a sealed bag. When ready to bake, just thaw and follow the baking instructions!
Can I use store-bought marshmallow fluff instead of homemade?
Yes, store-bought marshmallow fluff works perfectly! It’s quick, easy, and still creates that sweet, marshmallowy goodness that makes these cookies so special.
Can I decorate these cookies with other toppings?
Absolutely! You can sprinkle the cookies with colored sugar before baking, or add chocolate chips, sprinkles, or small candy pieces for a creative twist.
What if I don’t have heart-shaped cookie cutters?
No worries! If you don’t have heart-shaped cutters, any other shape will work – or you can just cut them into squares or circles for a simpler design.
How long will these cookies stay fresh?
These cookies should stay fresh for about 3 days at room temperature in an airtight container. If you want them to last longer, you can refrigerate them for up to a week.
