Gluten-Free Sugar Cookies That Hold Their Shape
Gluten-Free Sugar Cookies That Hold Their Shape
October is the month the cookie cutters come out. Halloween is three weeks away, and if your house is like mine, the pumpkins and ghosts start showing up on the kitchen counter long before the 31st.
Decorating sugar cookies with kids is one of those simple pleasures that should be easy. But gluten-free sugar cookies have a reputation: they spread. You cut a pumpkin, you get a blob. You cut a ghost, you get a puddle. The shape is the whole point of a cutout cookie, so this matters.
The problem is structural. Wheat flour forms a gluten network that holds the cookie's edges while the butter melts in the oven. Without gluten, the butter wins. The cookie spreads before the structure sets, and intricate shapes blur into circles.
Start with the flour. A 1-to-1 gluten-free baking blend works, but check that it contains xanthan gum, or add about half a teaspoon per cup of flour yourself. The gum replaces some of the binding power that gluten would have given you. Cup-for-cup blends without any binder are the reason most gluten-free sugar cookies spread.
Then mind the butter. Cream it with the sugar just until combined, no more. Over-creaming whips air into the dough, and that air expands in the oven and pushes the edges outward. Cold dough is the real secret weapon: chill the rolled dough for at least 30 minutes, cut your shapes, then chill the cut cookies on the tray for another 10 minutes before they go in. Cold butter takes longer to melt, which gives the flour time to set.
Roll the dough between two sheets of parchment instead of on a floured counter. Extra bench flour changes the flour ratio and dries the cookies out. With parchment, you roll evenly, peel the top sheet, cut the shapes, and lift the whole sheet onto the baking tray. No sticking, no extra flour.
Bake at 350 degrees Fahrenheit and pull the cookies when the edges just turn matte and the centers still look slightly soft. They firm up as they cool. Overbaking is what turns gluten-free cookies gritty and hard, so err on the side of underdone.
Now the icing. Royal icing is the classic choice for cutouts because it dries hard enough to stack the cookies in a tin or a party bag. Whisk powdered sugar with meringue powder (or pasteurized egg whites) and a little water, then tint it in small bowls. Black, orange, and purple cover every Halloween design a kid will dream up.
Use the outline-and-flood method. Pipe a border around the edge of the cookie with slightly thicker icing, let it set for a few minutes, then thin the rest of the icing with a few drops of water and flood the inside. A toothpick pulls the icing into the corners and pops any bubbles.
Give the icing a full day to dry if the cookies are going into gift bags. Royal icing looks dry after an hour but stays soft underneath, and stacking too early smudges the designs. Patience here is the difference between cookies that look store-bought and ones that look like a craft project gone wrong.
If you want the full recipe with exact measurements, bake times, and the flour blend that works best, here is my gluten-free sugar cookies with royal icing. Bake a batch this weekend and you will be three weeks ahead of Halloween.
