Discover Peterborough Ontario

The City of Peterborough sits along the Otonabee River with an easy, relaxed charm. It’s the kind of place you think you know, until you actually arrive and realize you underestimated it. The city isn’t just a stop on the way to cottage country. It has its own pulse, its own flavour, and a community that feels genuinely proud of where they live.

You can watch boats rise at the Lift Lock in one moment. Minutes later, you’re downtown following the trails along the river and Little Lake. The streets feel lively but never rushed. Local shops, small cafés, and musicians give the area a warm, lived-in feel. History is everywhere, but it blends naturally with the city’s creative streak.

What really stands out, though, are the small businesses. They give Peterborough its personality. They’re run by people who care deeply about what they make and how they share it. And tucked among these streets is one bakery that captures that spirit perfectly — a spot that feels like a discovery the moment you walk through the door.

Kawartha Butter Tart Factory: Peterborough’s Sweet Little Obsession

We first learned of The Kawartha Butter Tart Factory several years ago. We were on an autumn road trip to Bancroft, and passed their (old) location – a giant blue building northeast of Peterborough.  From that moment on, it has become necessary to visit whenever we are in Peterborough. Their current location sits in a simple building in Peterborough, but the moment you step inside, you get it. The smell alone could convince anyone to stay. Warm pastry. Brown sugar. Butter is doing its best work.

The place feels friendly and unfussy. Locals swing in for a quick box. Travellers hover by the counter, trying to act calm while their eyes dart between flavours. The staff moves with that easy confidence of people who know their product is good. The treats all look like they were made by someone who actually enjoys baking.  Despite the name, nothing here feels factory-made. You can see the handwork in every edge and swirl.

This bakery isn’t trying to be trendy or flashy. It’s all about the basics done really well. Good ingredients. Real technique. Zero shortcuts. And a whole lot of pride in a classic Canadian treat. If you’re anywhere near Peterborough, this place deserves a stop. And honestly, once you’ve had one tart, you’ll start planning your next visit before you hit the parking lot.

The Kawartha Butter Tart Factory is one of those spots you don’t just “visit.” You make a point of going.

The Best Butter Tarts In Peterborough

Butter tart Appearance

Each tart looks hand-shaped, with a little florette pattern that never repeats the same way twice. The pastry has natural variation, with some edges rising higher and creating a rustic, homemade look. The crust is evenly baked, with a warm golden hue that signals a proper blind bake. The filling settles into a glossy, amber top that catches the light. A slight overflow caramelizes along the rim, creating that thin, sugary edge bakers secretly love.

Crust

The crust has that light, flaky lift you only get from well-laminated pastry. It feels simple and classic, with no unnecessary fuss. The shell is thick enough to stay intact, even when you eat it one-handed. It never crumbles into chaos. Each bite gives a clean, crisp snap that signals a proper bake. There’s a gentle sweetness in the dough, just enough to balance the filling. The edges stay crunchy, thanks to a perfect golden finish. It’s a sturdy, well-structured pastry that holds its shape yet remains tender.

Butter Tart Filling – Real Butter

The filling is thick and smooth, with a soft, gelatinous set that holds its shape. It has a rich, buttery depth that hits fast. These are the hallmarks of a butter tart made with real butter. The brown sugar base gives it a warm, caramel sweetness without going overboard. The texture is velvety, almost custardlike, and it glides across your palate with zero graininess. There’s no sugar crystal hiding at the bottom, just a clean, even bake from top to base. The flavour leans bold and buttery, with a finish that lingers longer than you expect.


Crust-to-Filling Ratio

The tarts are filled right to the rim, with barely any overflow. Each bite delivers pure filling from top to bottom. There are no hidden air pockets or gaps, just a clean, even set. The ratio feels intentional, with the sturdy pastry supporting the generous interior. The crust never steals the spotlight, but it holds everything together beautifully. It’s a balanced build that lets the filling shine without overwhelming. These tarts travel well too, staying intact and delicious long after you leave the bakery.

Overall Experience

This tart delivers a rich, buttery hit from the first bite. The filling is smooth, creamy, and beautifully balanced. Nothing feels cloying or heavy, which makes the sweetness easy to enjoy. The crust holds firm, so you can eat it while walking without a single drip. No crumbling, no sticky fingers, no runaway filling. It’s a tidy, well-built tart that travels as well as it tastes. You can finish a whole one without feeling overwhelmed. It’s indulgent, but never too much — the kind of treat you enjoy anytime, anywhere.

Beyond the Butter Tarts

When you go on a roadtrip to Peterborough, make sure you have a cooler pack. Kawartha Butter Tart Factory doesn’t stop at butter tarts. While the majority of their shop is dedicated to their namesake item, their doughnuts deserve their own fan club. The fritters are enormous, packed with real fruit, and fried to a deep golden finish. Each one has that crackly, caramelized edge that bakers dream about. The cream-filled doughnuts are even wilder. They’re stuffed with housemade cream that’s so fresh it practically tries to escape. The filling is silky, light, and unapologetically rich. We never leave without buying a couple – lemon, raspberry, strawberry rhubarb, etc.  We always enjoy a cream puff donut on the Drive to Marmora – it’s messy, but worth it. These are the kind of doughnuts that break diets and ruin willpower. And honestly, they’re worth every bite. Their Cheese biscuits are also a must.

Staying Power of the Butter Tarts

These tarts don’t just travel well — they’re shockingly resilient. We grabbed a box on the way to a cabin near Bancroft and promptly forgot about them. They bounced around the car for days without losing their shape. No collapsed crusts. No leaking filling. When we finally opened the box at home, they still looked bakery-fresh. The pastry stayed crisp, and the filling kept its smooth, buttery texture. It was the kind of durability you only get from a properly baked tart.
