Why do marshmallows melt in cookies?

Marshmallows melt in cookies because they contain sugar and gelatin, which break down quickly under high heat. When baking Lucky Charms cookies, marshmallows soften and expand before they caramelize. If the oven temperature runs too high, they melt completely and disappear into the dough. That is why controlled baking with marshmallows matters. Always bake at 350°F and avoid overbaking. Slightly underbaked centers help Lucky Charms cookies keep visible marshmallow pockets.

Can I use regular marshmallows instead of mini ones?

Yes, but you must chop them into small pieces. Recipes using mini marshmallows work better because smaller pieces distribute evenly and melt gently. Large marshmallows create hollow gaps and uneven spreading. If you only have regular marshmallows, cut them into pea sized pieces and lightly coat them in flour before folding them into the dough. This step helps your lucky charm cookie maintain structure.

How do I keep Lucky Charms cookies soft?

To keep Lucky Charms cookies soft, measure flour carefully and avoid overbaking. Pull them from the oven when the edges look set but the centers still appear slightly soft. Store them in an airtight container with a slice of bread to maintain moisture. Brown sugar also plays a key role in softness because it retains more moisture than white sugar.

Can I freeze Lucky Charms cookie dough?

Yes, and freezing works extremely well. Scoop dough into balls and freeze them on a tray. Once firm, transfer them to a sealed freezer bag. Bake directly from frozen and simply add one to two extra minutes to the baking time. This method allows you to enjoy fresh Lucky Charms cookies anytime without preparing a full batch.
