How to Make Grandma’s Irish Sugar Cookies
Ingredients You’ll Need
✔ ½ cup granulated sugar – Sweetens the cookies and creates that crisp, sugar-coated exterior.
✔ ½ cup powdered sugar – Adds a soft, melt-in-your-mouth texture.
✔ 1 egg – Helps bind everything together.
✔ ½ cup butter, softened – For a rich, buttery flavor.
✔ ½ cup vegetable oil – Keeps the cookies light and tender.
✔ ½ teaspoon vanilla extract – Enhances the sweetness with a warm, comforting flavor.
✔ 2 cups all-purpose flour – The base of the cookie dough.
✔ ½ teaspoon baking soda – Helps the cookies rise slightly for a soft texture.
✔ ½ teaspoon salt – Balances the sweetness.
✔ ½ teaspoon cream of tartar – Adds a slight tang and ensures the cookies stay soft.
Step 1: Preheat the Oven
Before getting started, preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat to prevent sticking and ensure even baking.
💡 Pro Tip: If you like your cookies extra soft, you can chill the dough for 15-20 minutes before baking. This helps prevent them from spreading too much in the oven.
Step 2: Cream the Wet Ingredients
In a large mixing bowl, beat together:
✔ Granulated sugar
✔ Powdered sugar
✔ Butter (softened)
✔ Vegetable oil
✔ Egg
✔ Vanilla extract
Use a hand mixer or stand mixer to blend everything until the mixture is smooth and creamy. The combination of butter and oil ensures the cookies have rich flavor with a delicate, tender texture.
💡 Pro Tip: Make sure your butter is at room temperature this makes it easier to cream and helps create a smoother dough.
Step 3: Mix the Dry Ingredients
In a separate bowl, whisk together:
✔ 2 cups all-purpose flour
✔ ½ teaspoon baking soda
✔ ½ teaspoon salt
✔ ½ teaspoon cream of tartar
This step ensures that the leavening agents and salt are evenly distributed throughout the dough, so you don’t get any pockets of baking soda in your cookies.
Rolling, Baking, and Perfecting Grandma’s Irish Sugar Cookies
Now that we’ve mixed the buttery wet ingredients and whisked together the dry ingredients, it’s time to bring the dough together and shape these classic sugar cookies. This step is where the magic happens—rolling the dough in sugar for that signature crisp coating and baking them until they’re perfectly golden and soft inside.
Step 4: Combine the Wet and Dry Ingredients
Now, slowly add the dry ingredients to the bowl with the wet ingredients, mixing gradually to avoid overworking the dough. Stir until everything is fully combined—you should have a soft, slightly sticky dough that’s easy to work with.
💡 Pro Tip: If the dough feels too soft, let it chill in the refrigerator for 15-20 minutes. This makes it easier to roll into balls and helps the cookies keep their shape while baking.
Step 5: Form the Cookies
Now, it’s time to shape these sweet little treats!
1️⃣ Scoop out small portions of dough, about 1 inch in diameter (about the size of a walnut).
2️⃣ Roll each piece into a smooth ball using your hands.
3️⃣ Roll each dough ball in granulated sugar, coating it evenly. This gives the cookies that classic sugar-crusted finish when baked.
💡 Pro Tip: Want to add a festive St. Patrick’s Day twist? Mix a little green sanding sugar with the granulated sugar before rolling the cookies for a subtle green sparkle!
Step 6: Bake the Cookies
Now that the cookies are formed, place them on a prepared baking sheet, spacing them about 2 inches apart. They will spread slightly while baking.
1️⃣ Using the bottom of a glass or the palm of your hand, gently press down on each dough ball to slightly flatten it.
2️⃣ Bake in the preheated 350°F (175°C) oven for 10-12 minutes, or until the edges turn a light golden brown.
💡 Pro Tip: Keep an eye on them if you want softer cookies, take them out at 10 minutes when they’re just set. For a slightly crispier edge, bake them closer to 12 minutes.
Step 7: Cool the Cookies
Once baked, let the cookies sit on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely. This helps them set up properly and prevents breaking.
At this point, your kitchen is filled with the sweet aroma of butter, vanilla, and sugar and resisting the urge to grab one straight from the pan is the hardest part!
FAQs: Everything You Need to Know About Grandma’s Irish Sugar Cookies
These soft, buttery, melt-in-your-mouth sugar cookies are simple to make, but here are some commonly asked questions to help you get the best results every time!
1. Can I make the dough ahead of time?
Yes! You can prepare the dough in advance and store it in the refrigerator for up to 24 hours before baking. Just let it sit at room temperature for about 10-15 minutes if it becomes too firm to scoop.
2. Can I freeze these cookies?
✔ Freezing the Dough: Roll the dough into balls, coat them in sugar, and place them on a baking sheet in the freezer until firm. Then, transfer them to a freezer-safe bag and store them for up to 3 months. Bake directly from frozen, adding 1-2 extra minutes to the baking time.
✔ Freezing Baked Cookies: Once completely cooled, store them in an airtight container and freeze for up to 3 months. Let them thaw at room temperature before serving.
3. How do I store leftovers?
Store cookies in an airtight container at room temperature for up to 5 days. To keep them soft, place a slice of bread in the container—the cookies will absorb the moisture from the bread and stay fresh longer!
4. Can I add mix-ins to the dough?
Definitely! Try adding:
✔ A sprinkle of cinnamon – for a warm, cozy twist.
✔ Finely chopped nuts – almonds or pecans work great!
✔ Green sanding sugar – for an extra festive St. Patrick’s Day touch.
5. Can I make these cookies without cream of tartar?
Yes, but the texture will change slightly. Cream of tartar helps create a soft, chewy texture. If you don’t have it, you can replace it with an extra ½ teaspoon of baking powder instead.
