Frequently Asked Questions

How long will these cookies stay fresh? Store them in an airtight container at room temperature for 3-4 days. They can last up to a week in the refrigerator.

Why are my cookies spreading too much? There could be a couple of reasons. Did you use too much fat? Make sure you measure accurately. Also, chilling the dough for 30 minutes before baking can help them hold their shape.

Can I make the cookies ahead of time? Yes! The dough can be chilled for up to 2 days before baking.

My cookies are too dry/not soft enough? This could be from over-mixing the dough or over-baking the cookies. Try baking for a minute or two less next time.

How can I tell if the cookies are done? The cookies will be slightly cracked on top and may look a little underdone in the center. They will continue to set as they cool.

Substitutions and Variations

Shortening: You can substitute butter or vegan butter for shortening in a 1:1 ratio. Butter might make the cookies spread slightly more, so you may need to adjust baking time.

Buttermilk: Regular milk with a splash of vinegar or lemon juice can be used in a pinch. Let it sit for 5 minutes to curdle slightly.

Walnuts: Any nut you like can be used! Peanuts, cashews, pecans, or hazelnuts are all delicious options. You can even use a mix of nuts for extra flavor and texture.

Chocolate Chips: Add chocolate chips, chopped chocolate bars, or white chocolate chips to the dough for extra chocolate flavor.

Frosting: Instead of homemade frosting, you can drizzle the cookies with melted chocolate, white chocolate, or caramel sauce.

What to Serve with Rocky Road Cookies

Cold Beverage: A tall glass of cold milk or a cup of unsweetened iced tea would be refreshing.

Vanilla Ice Cream: A classic pairing! A scoop of vanilla ice cream alongside the cookie creates a homemade Rocky Road sundae experience.

Savory and salty: For something unexpected, try some lightly salted pretzels or popcorn. The saltiness will help balance the sweetness of the cookies.
