Frequently Asked Questions
Q: Can I substitute the all-purpose flour with a gluten-free alternative?
A: Yes, you can substitute all-purpose flour with a gluten-free 1:1 baking flour blend. Ensure the blend contains xanthan gum or a similar binding agent for the best texture. Note that the cookies may have a slightly different texture compared to the original recipe.
Q: Can I use quick oats instead of rolled oats?
A: Yes, you can use quick oats as a substitute for rolled oats. However, the texture of the cookies will be slightly less chewy and more uniform. Avoid using instant oats, as they may make the cookies too soft or mushy.
Q: What’s the best way to store these cookies?
A: Store the oatmeal cookies in an airtight container at room temperature for up to 5 days. If you’ve already added the cinnamon glaze, allow it to fully set before stacking the cookies in the container. For longer storage, you can freeze the cookies (with or without glaze) in a freezer-safe bag for up to 3 months.
Q: Why are my cookies spreading too much while baking?
A: Cookies may spread excessively if the butter was too soft or melted when creaming with the sugars. Make sure your butter is softened but not melted. Additionally, chilling the dough for 20-30 minutes before baking can help prevent spreading. Also, double-check your measurements for flour and oats to ensure the dough isn’t too wet.
Q: Can I make the glaze thicker or thinner?
A: To make the glaze thicker, add more powdered sugar, one teaspoon at a time, until you reach your desired consistency. To make it thinner, add more milk, one teaspoon at a time, while whisking continuously. Adjust slowly to avoid over-thinning or over-thickening.
Q: Can I add mix-ins like raisins or chocolate chips to the cookie dough?
A: Absolutely! You can fold in up to 1/2 cup of mix-ins such as raisins, chocolate chips, or chopped nuts after mixing in the oats. This adds extra flavor and texture to the cookies. Be mindful not to add too many mix-ins, as it may affect the structure of the cookies.
Q: How can I make these cookies dairy-free?
A: You can make these cookies dairy-free by substituting the butter with a plant-based butter or margarine. For the glaze, use a non-dairy milk such as almond milk or oat milk. Ensure any substitutions are unsweetened and unflavored to maintain the original taste of the recipe.
