Indulgence reaches new heights with these spectacular Irish Cream Jumbo Cookies. Each thick, bakery-style cookie delivers an extraordinary sensory experience - crisp edges giving way to a soft, gooey center packed with melty chocolate, crunchy toffee bits, and crushed chocolate sandwich cookies. The crowning glory is a smooth Baileys-infused glaze that hardens into a sweet shell, creating the perfect finishing touch. These generous, Levain-style treats capture the essence of Irish cream in cookie form, making them ideal for St. Patrick's Day celebrations or anytime you crave something truly special.
Last month, I brought these to a friend's dinner party instead of the typical wine or flowers, and they were the talk of the evening. Everyone kept asking how I achieved that perfect thick texture without the cookies spreading flat. My friend's husband, who typically passes on dessert, had two and declared them better than any bakery cookie he'd ever tried. The subtle hint of Baileys in both the dough and glaze made them sophisticated without being overwhelmingly boozy.
Essential Ingredients and Selection Tips
- Cold Butter: Using cold, cubed butter rather than room temperature is crucial for achieving that signature thick, bakery-style texture. The cold butter creates steam pockets while baking, helping the cookies rise rather than spread.
- Irish Cream Liqueur: Baileys or another Irish cream liqueur provides that distinctive flavor in both the dough and glaze. The alcohol bakes out of the cookies while leaving the flavor, making them appropriate for all ages.
- Mix-Ins Variety: The combination of both semi-sweet and milk chocolate with toffee bits and crushed cookies creates a complex texture and flavor profile. Each element serves a purpose - the chocolate melts, the toffee adds caramel notes, and the cookie pieces provide crunch.
- Espresso Powder: This optional ingredient doesn't make the cookies taste like coffee but rather enhances and deepens the chocolate flavor, creating a more complex taste profile.
What makes these cookies truly special is how each ingredient plays its role in creating the perfect texture and flavor balance. When I first developed this recipe, I was amazed at how well the Irish cream flavor came through without overwhelming the other elements. It's all about finding that perfect harmony.
Detailed Cooking Instructions
- Step 1: Master the Butter-Sugar Mixture
- Begin by cutting very cold butter into small cubes, then beat with both sugars for just 1-2 minutes. This is far less time than typical cookies require, and that's intentional - you want to combine the ingredients without incorporating too much air, which would cause the cookies to spread. The mixture should look somewhat lumpy rather than light and fluffy. This restrained mixing is key to maintaining the signature thick shape.
- Step 2: Incorporate Wet Ingredients Carefully
- Add the cold eggs one at a time, mixing just until each disappears into the batter. Then add the Irish cream liqueur and extracts, mixing minimally to combine. The cold eggs help maintain the cool temperature of the dough, which is essential for preventing spread during baking. The Irish cream here provides a foundation of flavor that will be enhanced by the glaze later.
- Step 3: Balance the Dry Ingredients
- Whisk the flour, cornstarch, baking soda, salt, and espresso powder thoroughly in a separate bowl before gradually adding to the wet ingredients. The cornstarch is crucial as it creates a tender texture by inhibiting some gluten development. Mix until just combined and no dry streaks remain - overmixing at this stage will develop too much gluten and result in tougher cookies.
- Step 4: Fold in Mix-ins with Intention
- Add all mix-ins at once and fold gently by hand using a sturdy spatula rather than the mixer. This preserves the chunks and prevents breaking down the cookie pieces too much. The goal is an even distribution while maintaining the integrity of each component. The variety of mix-ins ensures that every bite offers a different texture experience - from melty to crunchy.
- Step 5: Shape and Bake for Maximum Height
- Form large 5-6 ounce dough balls, shaping them tall rather than wide. Don't compact the dough too much; keep it loosely formed so the cookies maintain their height during baking. Place only 3-4 cookies per baking sheet to allow proper air circulation. The high oven temperature of 410°F creates that perfect contrast between crisp exterior and gooey interior in just 9-12 minutes of baking.

My first attempt at these cookies taught me valuable lessons about patience. I tried to move them too soon and ended up with broken cookies. Now I know that allowing them to cool completely on the baking sheet before transferring to a wire rack is crucial for maintaining their structure. That waiting period allows the interior to set while staying wonderfully soft.
Serving Inspiration
Transform these cookies into an elegant dessert by pairing them with a Baileys-spiked coffee or hot chocolate for an after-dinner treat. For a festive St. Patrick's Day presentation, arrange them on a platter with shamrock-shaped cookies and chocolate gold coins. I've even served these sliced in half horizontally with a scoop of vanilla ice cream sandwiched between for an extraordinary ice cream sandwich experience that my guests still talk about months later.

Sweet Variations
While the original recipe is perfect as is, I've developed several variations that offer delightful alternatives. For chocolate lovers, try replacing the white chocolate chips with dark chocolate chunks and adding a tablespoon of cocoa powder to the dough. During fall, I often swap the chocolate sandwich cookies for crushed gingersnaps and add a teaspoon of cinnamon for a seasonal twist. For a non-alcoholic version that still captures the Irish cream flavor, use Irish cream coffee creamer in place of the Baileys in both the dough and glaze.
Make-Ahead Options
The versatility of this recipe makes it perfect for planning ahead. The cookie dough can be prepared and refrigerated for up to 48 hours before baking, which actually improves the flavor as the ingredients have more time to meld. You can also freeze the shaped dough balls for up to 3 months - just add an extra minute or two to the baking time when cooking from frozen. The glaze can be prepared up to 3 days in advance and stored in the refrigerator; simply warm it slightly and stir well before using.

What began as an experiment with Irish cream in cookie form has become one of my signature recipes. There's something magical about the combination of thick, soft cookie with multiple texture elements and that hint of sophisticated Baileys flavor. While perfect for St. Patrick's Day celebrations, these cookies have earned their place in my year-round baking rotation. The joy on people's faces when they bite into these jumbo treats is all the proof I need that sometimes, bigger really is better when it comes to cookies.
Frequently Asked Questions
- → Can I make these cookies without alcohol?
- Yes! For an alcohol-free version, substitute the Irish cream liqueur in the cookie dough with 2 tablespoons of heavy cream or milk plus 1/4 teaspoon of coffee extract (or more vanilla). For the icing, replace the Baileys with 2-3 tablespoons of milk or cream and add 1/4 teaspoon of caramel extract. You'll still get a delicious cookie with similar flavors, just without the alcohol content.
- → Why do I need to use cold butter and eggs?
- Cold butter and eggs are key to creating thick, bakery-style cookies that don't spread too much during baking. The cold butter takes longer to melt in the oven, which gives the cookies time to set up before spreading too thin. This technique, along with the cornstarch in the recipe, helps create that perfect texture with soft centers and slightly crisp edges that you'd find in a gourmet bakery cookie.
- → Can I make these cookies smaller than jumbo size?
- Absolutely! While the recipe is designed for jumbo 5-6 oz cookies, you can make them standard size by forming 2-ounce balls. Reduce the baking time to 8-10 minutes and keep a close eye on them. You'll get approximately 16-20 regular-sized cookies instead of 8 jumbo ones. The texture might be slightly different, but they'll still be delicious.
- → What can I substitute for the chocolate sandwich cookies?
- If you don't have chocolate sandwich cookies (like Oreos), you can substitute with any chocolate cookie crumbs or pieces. Graham cracker crumbs mixed with cocoa powder work in a pinch, or you could use chocolate wafer cookies. Even brownie brittle or crisp chocolate biscotti broken into small pieces would work well. The goal is to add texture and another chocolate element to the cookies.
- → How long do these cookies stay fresh?
- These cookies will stay fresh in an airtight container at room temperature for 3-4 days. For longer storage, you can refrigerate them for up to a week or freeze them for up to 3 months. The Bailey's icing actually helps them stay moist longer than typical cookies. In fact, these cookies often taste better on the second day, as the flavors have had time to meld together and the icing has fully set.
- → Can I make the dough ahead of time?
- Yes! This cookie dough can be made up to 3 days ahead and stored in the refrigerator. You can also portion the dough into balls, freeze them on a baking sheet until solid, then transfer to a freezer bag for up to 3 months. When ready to bake, you can bake frozen dough balls directly from the freezer—just add 2-3 minutes to the baking time. The icing should be made fresh when you're ready to drizzle it over the cookies.
