by | Updated: October 1st, 2018 | Read time: 2 minutes

These are not the kind of bars you unwrap. And you probably don’t want to risk eating them in the car, or packing one for a day hike. These blueberry-lemon shortbread bars are for dessert. Their crumbly crust and jam-like filling are best enjoyed while seated, with fork in hand and a cup of hot coffee on the side. When the oven timer goes off and those warm, fresh berries fill the air, you’ll understand. This dessert deserves more than a snack break.
