Heat oven to 300° F.
Lightly coat bottom of a 9-inch baking dish with olive oil spray.
In a small bowl, mix dry ingredients together.
Add nut butter and fruit.
Mash together with a fork until mixture can be formed into a ball (You may need to add a bit more fruit or nut butter for dough to hold together.)
Press firmly into the bottom of baking dish to ensure a densely packed bar which won’t crumble. (dough will come about half-way up pan)
Lightly cut into 6 equal-sized bars.
Bake for 15 minutes.
Let cool, cut again along scored lines.
With a spatula, carefully remove from pan.
Wrap bars individually; freeze until needed.
