Why You'll Love This Recipe
About the Ingredients
2 1/4 cups (280g) all-purpose flour
Provides structure. For a softer texture, substitute up to 1/2 cup with cake flour, or use gluten-free 1:1 flour for a GF version.
1/2 teaspoon baking soda
Leavening agent that helps cookies spread slightly. Ensure it's fresh for optimal rise.
2 teaspoons cornstarch
The secret to extra-soft cookies. If you don't have cornstarch, use 1 extra egg yolk.
1/2 teaspoon salt
Balances sweetness and enhances flavor. Use fine sea salt for even distribution.
3/4 cup (170g) unsalted butter, softened
For a richer flavor, use browned butter (cooled) but reduce baking time slightly. Salted butter works if you reduce added salt to 1/4 tsp.
3/4 cup (150g) packed light brown sugar
Adds moisture and chewiness. Dark brown sugar gives a deeper molasses flavor.
1/4 cup (50g) granulated sugar
Provides crisp edges. You can use all brown sugar for a softer cookie.
1 large egg + 1 egg yolk
The extra yolk adds richness and tenderness. For a dairy-free option, use flax eggs.
2 teaspoons vanilla extract
Pure vanilla is best. For a twist, use 1 teaspoon vanilla and 1/2 teaspoon almond extract.
1 cup (170g) semi-sweet chocolate chips (optional)
Feel free to swap for white chocolate, butterscotch, or dried cranberries.
Tips & Tricks
- Use room-temperature butter and eggs for even creaming; cold ingredients lead to dense cookies.
- Don't overmix the dough once flour is added—stop when streaks disappear to avoid tough cookies.
- Chill the dough for 30 minutes if your kitchen is warm; this prevents excessive spreading.
- For uniform cookie size, use a cookie scoop (about 1.5 tablespoons) for even baking.
Pro Tips
Step-by-Step Instructions
1. Preheat Oven and Prep
Preheat oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone mats. In a medium bowl, whisk together flour, baking soda, cornstarch, and salt; set aside.
2. Cream Butter and Sugars
In a large bowl, using an electric mixer on medium speed, beat softened butter, brown sugar, and granulated sugar until light and fluffy, about 2 minutes. Scrape down the sides as needed.
3. Add Eggs and Vanilla
Add the egg and egg yolk, one at a time, beating well after each addition. Mix in the vanilla extract until combined. The mixture should look smooth and creamy.
4. Combine Dry Ingredients
Reduce mixer speed to low and gradually add the flour mixture, mixing until just combined. Do not overmix—the dough will be soft. Fold in chocolate chips if using.
5. Scoop Dough
Using a cookie scoop or tablespoon, drop rounded balls of dough (about 1.5 tablespoons each) onto prepared baking sheets, spacing them 2 inches apart. For even baking, make them uniform in size.
6. Bake to Golden Perfection
Bake in preheated oven for 10-12 minutes, until edges are golden brown and centers are still soft. The cookies will look slightly underdone in the middle—that's perfect. For crispier cookies, bake 2 minutes longer.
7. Cool and Serve
Let cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely. Enjoy warm for a gooey treat, or store in an airtight container for up to a week.
Delicious Variations
Chocolate Chip Walnut
Add 1/2 cup chopped walnuts along with the chocolate chips for a crunchy twist.
Oatmeal Raisin
Replace 1 cup of flour with 1 cup rolled oats and add 1/2 cup raisins and 1 teaspoon cinnamon.
Lemon Glazed
Omit chocolate chips, add 1 tablespoon lemon zest, and drizzle with a simple lemon glaze (1 cup powdered sugar + 2 tbsp lemon juice).
How to Store Grandma's Cookies Recipe
Refrigerator
Store in an airtight container at room temperature for up to 5 days. For longer storage, refrigerate dough (baked cookies can be refrigerated too) for up to 2 weeks.
Freezer
Freeze baked cookies in a freezer-safe bag for up to 3 months. You can also freeze unbaked dough balls—place on a baking sheet, freeze until solid, then transfer to a bag; bake from frozen, adding 2 minutes to the baking time.
Reheating
To refresh cookies, microwave for 10 seconds, or reheat in a 300°F (150°C) oven for 5 minutes to restore crispness.
Frequently Asked Questions
Q: Why are my cookies flat?
Flat cookies usually result from over-softened butter or dough that's too warm. Chill the dough for 30 minutes before baking and ensure your butter is softened but not melted.
Q: Can I use margarine instead of butter?
Yes, but the texture will be slightly different. Margarine has more water and less fat, leading to thinner, less flavorful cookies. For best results, stick with real butter.
Q: How do I make cookies chewy instead of cakey?
Use more brown sugar than white, add an extra egg yolk, and don't overmix the dough. Also, slightly underbake them—remove from the oven when centers are just set.
Q: Can I freeze the cookie dough?
Absolutely! Scoop the dough into balls, freeze on a baking sheet, then transfer to a freezer bag. Bake from frozen, adding 2-3 minutes to the baking time.
