Unregular Bakery in New York City is bringing an exciting fusion dessert to the table just in time for St. Patrick’s Day 2025 – the Guinness Bombolone. This innovative treat marries traditional Italian pastry with iconic Irish flavors, creating a unique culinary experience for dessert enthusiasts. Launching on March 14, 2025, this specialty pastry features non-alcoholic Guinness pastry cream, Guinness pearls, and a sprinkle of matcha crumble for a perfectly balanced flavor profile. The creative minds behind Unregular Bakery have crafted a dessert that honors both Italian craftsmanship and Irish tradition, making it the perfect indulgence for St. Patrick’s Day celebrations.
A Taste of Two Traditions: The Guinness Bombolone Experience
The Guinness Bombolone represents a brilliant cultural fusion of Italian pastry-making techniques and Irish flavor inspiration. At its heart, this specialty bombolone (Italian-style filled donut) features a non-alcoholic Guinness pastry cream that captures the distinctive malty depth of Ireland’s famous stout without the alcohol content. The filling provides a rich, complex flavor that pairs perfectly with the light, fluffy texture of the traditional bombolone dough.
What makes this pastry truly stand out are the Guinness pearls decorating the top, which deliver concentrated bursts of that beloved stout flavor with each bite. These pearls aren’t just decorative—they’re functional flavor bombs that enhance the eating experience. The matcha crumble garnish adds an unexpected twist, offering earthy, slightly bitter notes that contrast beautifully with the richness of the Guinness components.
The Guinness-infused dessert trend has been gaining momentum, but Unregular Bakery’s approach stands apart with its thoughtful balance of flavors. The bombolone exemplifies how seemingly disparate culinary traditions can harmonize perfectly when handled with care. This isn’t simply an Italian pastry with an Irish flavor slapped on—it’s a carefully calibrated creation where each element enhances the others.
For those who appreciate flavor complexity, this pastry delivers a dynamic eating experience that evolves from first bite to last. The initial sweetness of the bombolone dough gives way to the malty depth of the Guinness cream, punctuated by concentrated flavor from the pearls, with the matcha providing a clean, slightly astringent finish that refreshes the palate.
The Entrepreneurial Journey Behind Unregular Bakery
Unregular Bakery’s story is as compelling as their pastries. Founded by Gabriele Lamonaca and Paola Sinisgalli in May 2021, the business began humbly as a Roman-style pizzeria operated from their apartment. What started as a passion project during challenging times has blossomed into one of New York City’s most innovative bakeries, now specializing in bomboloni and croissants from their brick-and-mortar location in Union Square.
The founders’ journey reflects the entrepreneurial spirit that drives much of New York’s food scene. “We started with a simple idea—bringing authentic Italian flavors to New Yorkers, but with creative twists that make them unique,” explains Gabriele Lamonaca. Their pivot from pizza to pastry came naturally as they discovered their bomboloni creations were garnering particular attention.
Their Union Square location at 124 4th Avenue has become a destination for pastry lovers seeking something beyond the ordinary. The bakery’s mission of bringing high-quality, modern Italian food concepts to New York City is evident in every aspect of their operation—from ingredient sourcing to presentation. Innovative dessert recipes like theirs have transformed the city’s pastry landscape, encouraging other bakers to experiment with cross-cultural flavors.
What sets Unregular Bakery apart is their willingness to challenge conventions while respecting traditional techniques. This balance of innovation and tradition has earned them a loyal following among New Yorkers who appreciate both culinary heritage and creative exploration. Their success story serves as inspiration for food entrepreneurs looking to carve out a unique niche in a competitive market.
Beyond the Bombolone: Unregular’s Signature Creations
While the Guinness Bombolone is capturing attention this St. Patrick’s Day, Unregular Bakery has built its reputation on a range of innovative specialty items. Their Bombaspritz, a playful pastry interpretation of the classic Italian Aperol Spritz cocktail, has become a signature offering that bridges the worlds of cocktails and desserts. The balance of bitter and sweet notes in this creation demonstrates the bakery’s knack for translating beverage flavors into pastry form—a skill also evident in their new Guinness creation.
The 1000 Pain au Chocolat stands as a testament to their craftsmanship, featuring meticulously layered chocolate throughout a perfectly laminated croissant dough. This labor-intensive creation showcases the technical skill behind their seemingly playful approach. Their Bufala Croissant, incorporating buffalo milk cream, brings an unexpected richness and tanginess that has converted even traditional croissant purists.
Each of these creations shares a common thread—thoughtful ingredient combinations that surprise and delight. “We’re not interested in shock value,” notes Paola Sinisgalli. “Every unusual ingredient or combination must earn its place by contributing something meaningful to the final experience.” This philosophy explains why their experimental flavors succeed where others might fail.
For those looking to expand their pastry horizons, Unregular Bakery offers an education in how global flavors can be respectfully incorporated into familiar formats. Their seasonal rotation ensures there’s always something new to discover, making each visit a unique experience. The bakery has effectively created a following of culinary adventurers who trust their flavor judgment implicitly.
Celebrating St. Patrick’s Day with Italian Flair
Unregular Bakery is transforming the traditional St. Patrick’s Day celebration with their cross-cultural approach. From March 14-17, 2025, their Union Square location will feature festive decorations honoring both Irish tradition and Italian pastry heritage. This four-day celebration positions the Guinness Bombolone as a centerpiece of their seasonal offerings, bridging two vibrant food cultures in one delicious package.
The timing of this release aligns perfectly with the growing trend of creative St. Patrick’s Day treats that go beyond the standard green beer and soda bread. “We wanted to create something that honors the spirit of St. Patrick’s Day while staying true to our Italian roots,” explains Gabriele. “The Guinness Bombolone does exactly that—it’s a respectful fusion that celebrates both traditions.”
Social media will play a key role in spreading awareness of this special offering. Customers are encouraged to share their experience with the Guinness Bombolone on TikTok and Instagram using @unregularbakery, creating a virtual celebration that extends beyond the physical bakery space. This strategy has proven effective for previous limited-time offerings, generating buzz through authentic customer enthusiasm rather than traditional advertising.
For those unable to visit during the St. Patrick’s Day weekend, the Guinness Bombolone offers inspiration for St. Patrick’s Day green desserts and other holiday-themed treats. The bakery’s willingness to experiment with seasonal themes while maintaining their Italian identity demonstrates how food can bridge cultural divides and create new traditions.
Bombolone Fest 2025: A Celebration of Italian Pastry
The Guinness Bombolone ties into a larger celebration of Italian pastry culture—Bombolone Fest 2025, scheduled for February 8, 2025. Organized in collaboration with The Underground Donut Tour, this festival showcases the diversity and creativity of bomboloni in New York City. Unregular Bakery will feature prominently as one of the pioneers bringing this traditional Italian pastry to broader attention in the American market.
The festival, which can be explored further at bombolonefest.com, represents the growing community of pastry enthusiasts who appreciate the artisanal approach to sweet treats. “Bombolone Fest is not just about eating delicious pastries—though there’s plenty of that,” says Paola. “It’s about celebrating the craft, sharing techniques, and pushing boundaries of what’s possible with this format.”
For those interested in Italian pastry traditions, the festival offers demonstrations, tastings, and opportunities to learn from masters of the craft. The Guinness Bombolone will serve as a preview of the creative potential that will be on full display at the festival. This connection between the St. Patrick’s Day offering and the larger festival creates a narrative thread that strengthens both events.
The growing popularity of bomboloni in New York represents a shift in the city’s pastry landscape, with consumers increasingly seeking out authentic international treats with modern twists. Local dessert shops across the city are responding to this demand, creating a rich ecosystem of pastry innovation that benefits both creators and consumers.
The Creative Spark: Founders Share Their Inspiration
The creative vision behind the Guinness Bombolone offers insight into Unregular Bakery’s innovative approach to pastry. “We were brainstorming for St. Patrick’s Day and wanted to create something that wasn’t just superficially Irish—no green food coloring or shamrock shapes,” explains Gabriele Lamonaca. “We kept coming back to the deep, complex flavor of Guinness and how beautifully it could complement our bombolone dough.”
The development process involved multiple iterations to achieve the perfect balance. “The challenge was capturing the essence of Guinness without the alcohol, while ensuring it harmonized with rather than overpowered the bombolone,” notes Paola Sinisgalli. “The matcha element came later, almost by accident during testing, when we discovered how perfectly its subtle bitterness complemented the malty sweetness.”
Their approach embodies a philosophy that guides all their creations: respect for traditional techniques coupled with fearless experimentation. “We’re Italian bakers at heart, but we’re also New Yorkers,” Gabriele adds. “That means honoring tradition while embracing the multicultural inspiration this city provides.” This blend of reverence and innovation defines the Irish-inspired treats they’ve created.
For home bakers looking to experiment with cross-cultural pastries, the founders suggest starting with familiar formats and introducing new flavors gradually. “Begin with a pastry technique you’ve mastered, then introduce one unexpected element,” advises Paola. “Pay attention to balance—every component should enhance the others, not compete.” This wisdom applies whether you’re working with churro-inspired desserts or other fusion creations.
The Guinness Bombolone will be available at Unregular Bakery (124 4th Avenue, New York, NY 10003) from March 14-17, 2025.
