What Ingredients You Will Need

This Irish Cream Butter Cookie Loaf uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these are pantry staples, and a few special touches bring it to life.

• Unsalted Butter, softened (adds richness and that classic buttery bite) – I recommend using a good-quality brand like Kerrygold for that authentic Irish touch.
• Granulated Sugar (for sweetness and structure)
• Brown Sugar, packed (adds a lovely caramel note)
• Large Eggs, room temperature (helps bind the loaf and add moisture)
• Irish Cream Liqueur (the star here! Use your favorite brand like Baileys for the best flavor)
• All-Purpose Flour (for the tender crumb)
• Baking Powder (to give it a gentle lift)
• Salt (balances the sweetness)
• Vanilla Extract (deepens the flavor profile)
• Optional: Green Food Coloring (if you want that festive St. Patrick’s green hue without affecting flavor)
• Powdered Sugar (for a simple glaze or dusting)

If you’re feeling adventurous, you can swap all-purpose flour for almond flour to make a gluten-free version — just keep in mind the texture will be a little different, but still delicious. For a dairy-free spin, try swapping butter for coconut oil and use a dairy-free Irish cream alternative or a coffee-flavored syrup (great for those avoiding alcohol). Fresh mint or finely chopped pistachios make great mix-ins, too!

Equipment Needed

• Loaf Pan: A standard 9×5-inch (23×13 cm) loaf pan works perfectly. If you don’t have one, a similarly sized baking dish will do.
• Mixing Bowls: Medium and large bowls to mix wet and dry ingredients separately.
• Electric Mixer or Stand Mixer: Helps cream the butter and sugar until light and fluffy, but a sturdy whisk and some elbow grease can work in a pinch.
• Measuring Cups and Spoons: For accuracy, especially with baking powder and Irish cream.
• Spatula: Essential for folding ingredients without overmixing.
• Cooling Rack: To let the loaf cool evenly and prevent sogginess.

If you’re on a budget, many of these items can be found in affordable sets at your local store or online. I’ve tried mixing by hand many times, but honestly, the mixer saves so much time and effort for this recipe — especially since you want that butter perfectly creamed.

Preparation Method

1. Preheat your oven to 350°F (175°C) and grease your 9×5-inch loaf pan lightly with butter or non-stick spray. Line it with parchment paper if you want an easy release.
2. Cream the butter and sugars: In a large mixing bowl, beat 1 cup (227 g) softened unsalted butter, 3/4 cup (150 g) granulated sugar, and 1/4 cup (50 g) packed brown sugar until light and fluffy, about 3-4 minutes. You’ll know it’s ready when the mixture looks pale and smooth.
3. Add eggs one at a time: Crack in 2 large eggs, one by one, beating well after each addition. This helps keep the batter smooth and emulsified.
4. Mix in the Irish cream liqueur and vanilla extract: Pour in 1/4 cup (60 ml) Irish cream and 1 teaspoon vanilla extract. The batter will take on a lovely aroma at this point—pause and breathe it in. If you want that festive green color, add a few drops of green food coloring now and stir gently until evenly tinted.
5. Combine the dry ingredients: In a separate bowl, whisk together 2 cups (250 g) all-purpose flour, 1 1/2 teaspoons baking powder, and 1/2 teaspoon salt.
6. Fold dry ingredients into wet: Gradually add the flour mixture to the wet ingredients, folding gently with a spatula until just combined. Don’t overmix—the batter should be thick but smooth, with no visible streaks of flour.
7. Transfer batter to the loaf pan: Scrape the batter into your prepared pan and smooth the top with a spatula. Give it a little shake to settle the batter evenly.
8. Bake: Place in the oven and bake for 45-50 minutes. Start checking at 45 minutes by inserting a toothpick in the center — it should come out clean or with a few moist crumbs. If it needs more time, check every 3 minutes to avoid over-baking.
9. Cool: Let the loaf cool in the pan for 15 minutes, then transfer to a wire rack to cool completely. This helps keep the crumb tender and not soggy.
10. Optional glaze: Whisk 1/2 cup (60 g) powdered sugar with 1-2 tablespoons Irish cream (adjust for thickness) and drizzle over the loaf once cool for an extra touch of sweetness and flair.

Pro tip: If your batter feels too thick after adding Irish cream, a splash of milk (up to 2 tablespoons) can help loosen it just a bit without sacrificing texture. And remember, patience is key—resist the urge to slice while hot or you’ll get a crumbly mess!

Cooking Tips & Techniques

Getting this Irish Cream Butter Cookie Loaf just right is about a few small details that make a big difference. For starters, creaming your butter and sugars thoroughly is key to that tender, melt-in-your-mouth crumb. I learned the hard way that rushing this step can leave your loaf dense and heavy.

Using room temperature eggs helps them incorporate better, so take them out about 30 minutes before baking. When mixing the dry ingredients in, fold gently — overmixing develops gluten and makes the loaf tough, and nobody wants that.

Keep an eye on the baking time because ovens vary. I’ve had batches that needed a little longer, and some come out perfect right at 45 minutes. A toothpick test is your best friend here.

Also, don’t skip the cooling time! It’s tempting to dig in right away (I get it), but letting it rest ensures the loaf sets up and slices beautifully without crumbling.

One last tip: if you want to boost the Irish cream flavor without adding more liquid, a couple drops of Irish cream extract can do wonders without affecting texture.

Variations & Adaptations

This Irish Cream Butter Cookie Loaf is pretty versatile. Here are some fun ways to make it your own:

• Non-Alcoholic Version: Swap the Irish cream liqueur for Irish cream-flavored coffee creamer or a mix of vanilla and coffee extracts for a similar flavor without alcohol.
• Nutty Twist: Add 1/2 cup chopped toasted pecans or walnuts to the batter for extra crunch and richness.
• Chocolate-Chip Upgrade: Stir in 1/2 cup mini chocolate chips for a sweet surprise that pairs beautifully with Irish cream.
• Gluten-Free: Use a gluten-free all-purpose flour blend and ensure your baking powder is gluten-free. Texture will be a bit different but still delightful.
• Seasonal Flair: During spring, fold in fresh or frozen raspberries for a burst of tartness that balances the buttery sweetness.

Personally, I once swapped half the butter for browned butter, which added a toasty, nutty depth that was unexpectedly delicious. Give it a try if you want to impress your brunch guests!

Serving & Storage Suggestions

This loaf is best served at room temperature, maybe with a hot cup of coffee or tea to mellow out its rich, buttery flavors. It’s a fantastic centerpiece for a St. Patrick’s Day brunch or an afternoon snack that feels special but not fussy.

Leftovers keep well wrapped tightly in plastic wrap or stored in an airtight container at room temperature for up to 3 days. For longer storage, slice and freeze the loaf, wrapped individually or in a freezer bag, for up to 3 months.

When reheating, I find popping a slice in the toaster oven for a couple of minutes brings back that fresh-baked warmth and soft crumb texture. You can also microwave it briefly, but watch out for drying it out.

Over time, the Irish cream flavors meld deeper into the loaf, making leftovers even more flavorful the next day. Just don’t tell anyone you saved some — it’s tough to resist!
