Tips & Substitutions

For a richer flavor, consider using brown sugar instead of white sugar. If you prefer a healthier option, substitute half of the margarine with applesauce. Make sure your baking sheets are truly ungreased to prevent sticking. For a twist, add chopped nuts or dried fruit to the dough. Ensure even baking by rotating the sheets halfway through.

Frequently Asked Questions

Can I use gluten-free flour for this recipe?

Yes, you can substitute regular flour with a gluten-free flour blend. Make sure it is a 1:1 ratio to maintain the texture of the cookies. You might need to adjust the liquid slightly, as gluten-free flours can absorb moisture differently.

How do I prevent the cookies from spreading too much?

To prevent spreading, chill the dough for at least 30 minutes before baking. You can also try adding a bit more flour if the dough seems too wet. Ensure that your margarine is at room temperature, not melted, as melted margarine can lead to flatter cookies.

What can I use instead of sweetened condensed milk?

If you don't have sweetened condensed milk, you can make a quick substitute by simmering 1 cup of milk with 1/3 cup of sugar until it reduces by half. Alternatively, a vegan version can be made using coconut milk and sugar, though the flavor will differ slightly.
