My Lingonberry Jam Tart with Cardamom is an easy one bowl Scandinavian inspired shortbread crumble tart with a fabulous flavor combo. I sidetracked my diet for a second slice, and it was worth it!
Preheat the oven to 350F and set a rack in the center positon.
Cream the butter, sugar, cardamom, salt, and vanilla in a stand mixer fitted with the paddle attachment. You can also do this by hand, but be sure to cream everything well.
Gently blend in the flour.
Mix just until the dough is a coarse crumbly texture, with no dry flour left.
Take 2/3 of the dough and put it in the bottom of your tart pan.
Press down with your fingers so it is flat and even. If the dough sticks, lightly flour your fingers. You can use the flat bottom of a measuuring cup to help tamp it down. Note: you are not looking to go up the sides of the tart pan, you are just making a flat bottom crust.
Dollop your jam evenly over the dough. Then spread it out evenly.
Using your fingers toss the remaining crumbled dough with the oats, just to combine.
Crumble the topping over the jam, evenly. It's fine if some of the jam shows through.
Bake for 35 minutes. If the top seems to be browning too much, cover loosely with foil towards the end of baking. When done the shortbread should still be pale with just a hint of golden color in spots.
Cool the tart for 15 minutes, then loosen the edges with a knife (in case any jam has stuck) and remove the sides of the pan.
You can slice while warm, but for sharper cuts, let cool before slicing. Serve with a dollop of whipped cream if you like.
Notes
For a slightly 'jammier' tart you can add a bit more lingonberry jam for the filling.
