What you need for the Blueberry Crumble Bars

8 × 8-inch skillet: These bars are made in a specific pan for a reason, don’t change it. Using a smaller pan will create thick bars and a larger pan will create very thin bars that won’t hold together.

fine almond flour– When shopping for almond flour, there are usually two types of almond flour to choose from. It can be confusing because they may be called different things. be sure to buy extra-fine or blanched almond flour. It is a cream color.

The other almond flour options on the shelves are almond flour or raw almond flour, which is coarser. Do not use this type of flour for these bars.

fresh blueberries– We always prefer fresh blueberries for this recipe. If you must use frozen blueberries, be sure to let them thaw, discard any excess moisture, and then boil them.

We do not recommend substituting almond flour for any other flour.
