Mini Blackberry Cheesecake Tarts with Walnut Crust

Oat and walnut tart crusts filled with creamy blackberry and topped with ginger peanut brittle.

With true spring happening (where you can store your winter coat with confidence), I’m loving delicate, mini-food. Little dishes that let spring flavors shine. The kind of foods you can pass around as you languidly lounge in the garden with a giant bottle of rosè in the kind of outfit you definitely would need to iron.  Or maybe a bridal shower or baby shower. Or cat shower? Should we make those a thing? Some kind of event along those lines. These mini blackberry ‘cheesecakes’ with oat and walnut crusts are a good make ahead dessert that have well balanced flavors with the pretty factor. Cat shower or not.

Typically my biggest gripe with delicate foods that pop up every April is they’re usually too sweet or too one-note-boring. Sometimes little foods are only made for the cute vibes. This recipe is any thing but boring. With these tarts, the crust is nutty with toasted walnuts and only lightly sweetened with some brown sugar. The filling is pure and simple ingredient Blackberry siggi’s which, because it’s lower in sugar and high in protein, makes the perfect creamy filling. You taste blackberry, not straight up sugar like most yogurts. On top, we’ve got ginger peanut brittle that is now a staple in our house (all peanut brittle should have intense ginger) and also some fresh blackberries dusted with rosemary salt.This little bit of herbal salt pulls in some outdoorsy aromas and enhances the other flavors.

The oat and walnut crust that has become my go-to recipe for tarts. I’m really proud of that recipe since it has become so versatile for me. The tart shells actually hold their shape making them beautiful for a cake stand or platter (and to walk around with if you want). They’re great to make a day in advance and fill a few hours ahead of serving. 

I know some of you will look at this recipe and think ‘no way am I making peanut brittle’ or ‘no way am I making herb salt’ but like with all of our recipes, there is a reason they’re here. We tried these tarts with and without each component and while the tarts are cute and good without peanut brittle or herb salt, together they make it elevated and balanced. But because I really do like you and I can see your brain working out how to take a short cut, if you don’t want to make peanut brittle you can buy it, or at the very least, chop up some roasted honey salted peanuts on top.
