Storage Tips
These yummy chocolate marshmallow cookies stay fresh for up to 5 days when kept in an airtight container at room temperature. The marshmallow center makes them a bit sticky, so try placing wax paper between layers if you’re stacking them. Want to keep them longer? Pop them in the freezer! They freeze beautifully for up to 3 months – just wrap them well to prevent freezer burn.
Baking Tips
The secret to perfect chocolate marshmallow cookies is in the timing! Keep an eye on them during the first 8-minute bake – they should look set but still slightly soft in the middle. When you add the marshmallow halves, place them cut-side down and press very gently. The extra 2 minutes in the oven will make the marshmallows puffy and soft, but not brown. Let them cool completely before adding frosting, or it’ll melt right off!
Fun Variations
Love to mix things up? Try adding 1/2 cup of mini chocolate chips to the cookie dough for extra chocolatey goodness. For a minty twist, add 1/4 teaspoon of peppermint extract to the frosting. You can also swap the vanilla marshmallows for flavored ones – strawberry marshmallows make these cookies extra special! For holidays, sprinkle some colorful sprinkles on top of the frosting while it’s still soft.
Serving Ideas
These cookies are amazing with a cold glass of milk! For a sweet dessert table, stack them on a pretty plate and add some fresh berries around the edges. They’re perfect for bake sales, cookie swaps, or afternoon tea. Want to make them extra fancy? Serve them slightly warm (10 seconds in the microwave) with a scoop of vanilla ice cream on the side.
