Making pies and tarts can be intimidating, but this pear and raspberry tart starts with a simple Biscoff cookie crust that you press into a tart pan rather than having to make a pastry crust from scratch.

The custard filling comes together by whisking all of the ingredients in a bowl and then covers the chopped fruit in the crust - it doesn't get much easier than that!

This tart recipe was inspired by Bang Bang Pie & Biscuits here in Chicago. I tried their pear and raspberry buttermilk pie over the summer and I could not stop thinking about it, it was so good!! If you ever have a chance, I highly recommend stopping in and grabbing a slice of pie there.

Ingredients

Biscoff cookies are crushed to make the pie crust. Collect these cookies on your next flight, or purchase them in the cookie aisle of your grocery store.
Buttermilk adds creaminess and a slight tang to the custard filling.
Vanilla extract helps flavor the custard.
Canned sliced pears and fresh raspberries top the custard to make the best fruit tart! Be sure to grab a can of pears that doesn't have any sugar added.

See recipe card below for a full list of ingredients and measurements.

Substitutions & Variations

Very ripe, peeled pears can be used in place of the canned pears. Or, completely swap the pears for canned peaches.
Use graham crackers instead of Biscoff cookies for a graham cracker crust. Follow my graham cracker pie crust recipe for this variation.
Swap in any variety of berries, such as blueberries or blackberries, in place of the raspberries. I do not recommend using frozen berries in this recipe.

Expert Baking Tips

I like to use the bottom of a measuring cup or small glass to help press the cookie crust into the tart pan. It helps get the crust even and create smooth edges.
You can use a whisk to make the buttermilk filling, or you can place all of the ingredients in a blender or use an electric hand mixer to combine - whichever you prefer!
Place a baking sheet on the oven rack underneath the tart pan to catch any leaks when the buttermilk pie is baking.

Recipe FAQs

What makes this a tart and not a pie?

This fresh raspberry tart recipe has a cookie crumb crust that is baked in a tart pan rather than a pie plate. Tart pans have a 90-degree, often fluted edge versus a pie plate that angles out and often holds more volume of filling.

Can I substitute the buttermilk?

Since the buttermilk is such an important ingredient in this recipe, I do not recommend substituting it with anything else.

Why did my tart filling sink in?

This could be from having it cool down too quickly. Leaving it in the oven after turning it off helps prevent this. Regardless, it will still be delicious!

Can this tart be made in a pie dish?

Yes, but it may be more shallow or deep depending on the size of the pie pan.
