Tropical Mango Marshmallow Cookies

09/21/2025 | Bonia Bakery |

As summer comes to an end, I really wanted to end it with a bang—cookie style—but in a way that felt completely different from any other cookie I’ve made before. Naturally, my mind went straight to mangos. There’s something about that sweet, tropical flavor that just screams sunshine and lazy summer days.

And then it hit me… marshmallows. I was like, WAIT… yes! A little gooey, pillowy marshmallow center paired with soft, chewy mango cookies and a buttery graham cracker swirl? It was perfect. The flavor combination instantly brought to mind the classic tropical treats we all love, but in a totally new and playful cookie format.

These cookies are soft, tropical, and chewy with a subtle crunch from the graham cracker swirl. Topping them with marshmallow fluff adds a creamy, fun surprise in every bite. From the first taste, it felt like summer condensed into a cookie—sunshine you could hold in your hand.

Whether you’re baking for the last backyard BBQ of the season, a special brunch, or just because you want a little sunshine in your kitchen, these Tropical Mango Marshmallow Cookies are cheerful, creative, and irresistibly delicious.

Ingredients (Makes 10 large cookies)

Mango Cookie Dough:

  • 1 ¼ cups unsalted butter, room temperature
  • 1 ¼ cups granulated sugar
  • 38 g freeze-dried mango, ground to a fine powder
  • 1 small egg
  • Few drops orange food coloring (optional)
  • 1 ¾ cups all-purpose flour
  • ¼ tsp baking soda
  • 1 ¼ tsp salt

Graham Cracker Swirl:

  • 4–5 graham cracker sheets, crushed to crumbs
  • ¼ tsp kosher salt
  • ½ tsp honey (10 g)
  • 1 ¼ Tbsp unsalted butter, melted
  • 1 Tbsp water

Topping:

  • 4 oz marshmallow fluff

Directions

  1. Prep baking sheets: Line two large baking sheets with parchment paper or silicone mats.
  2. Make the cookie dough:
    • In a stand mixer, beat butter and sugar with the paddle attachment until light and creamy.
    • Add freeze-dried mango powder and optional food coloring, beating until combined.
    • Mix in the egg until fully incorporated.
  3. Combine dry ingredients: Whisk together flour, salt, and baking soda in a separate bowl. Gradually fold into wet ingredients until no streaks remain.
  4. Make the graham cracker swirl:
    • Combine graham cracker crumbs and salt in a medium bowl.
    • Drizzle in honey and mix, then add melted butter.
    • Add water gradually until mixture forms wet crumbles (don’t overdo it).
  5. Layer the dough:
    • Fold portions of mango dough together with bits of graham cracker swirl. Use your hands to gently incorporate the swirl evenly.
    • Chill dough for at least 1 hour.
  6. Scoop and divot:
    • Preheat oven to 350°F (175°C).
    • Scoop dough (about 2 tablespoons per cookie) and make a deep divot in each ball.
    • Place 6 divoted cookie balls on each baking sheet.
  7. Add marshmallow fluff: Spoon or pipe marshmallow fluff into each divot.
  8. Bake: Bake 10–13 minutes until edges are lightly golden and centers are set. Let sit 5 minutes before transferring to a wire rack to cool completely.

Storage Tips:

  • Store in an airtight container at room temperature for up to 3 days.
  • Refrigerate for up to 1 week if needed.
  • Freeze baked cookies (without marshmallow) for up to 2 months; add marshmallow after thawing.

These Mango Cookies with Graham Cracker Swirl are a fun, tropical, and creative way to end the summer on a high note. Soft, chewy, sweet, and a little gooey in the center—every bite is a mini vacation!
