FAQs

How strong is the mint flavor in these cookies?

The mint flavor is noticeable but not overpowering. You can adjust the amount of peppermint extract to suit your taste.

Can I make these cookies without food coloring?

Yes, the green food coloring is optional and only used for appearance. It won’t affect the taste.

What kind of cocoa powder should I use?

Use unsweetened natural cocoa powder for the best balance of flavor and texture.

Can I prepare the dough ahead of time?

Yes, you can make the cookie dough in advance and store it in the refrigerator for up to 48 hours.

Can I freeze the cookie dough?

Absolutely. Portion the dough into balls and freeze. Bake from frozen with a few extra minutes added to the baking time.

Can I make these cookies vegan?

You can try substituting with vegan butter and egg replacements, though results may vary slightly in texture.

Why are my cookies spreading too much?

Too-soft butter or overmixing can cause excess spreading. Chill the dough if needed before baking.

Can I use mint extract instead of peppermint?

Yes, though mint extract often includes spearmint and has a slightly different flavor. Peppermint gives a more classic taste.

Do I need to chill the dough?

It’s not required, but chilling can help prevent spreading and enhance the texture.

What’s the best way to apply the filling?

Use a piping bag for clean edges, or spread it with a spoon or offset spatula.
