Step 1

Preheat the oven to 350 degrees F.

Step 2

In a medium bowl, whisk together the oats, flour, brown sugar, and salt.

Step 3

Add the butter and cut it into the dry ingredients with a pastry blender or a couple forks until the mixture is crumbly and the butter is evenly cut in. Set aside.

Step 4

In another bowl, add the blackberries, sugar, flour and lemon juice. Stir until combined.

Step 5

Lightly grease a 9X13-inch pan and spread the fruit mixture on the bottom.

Step 6

Sprinkle the crisp topping evenly over the top.

Step 7

Bake for 45 minutes until the fruit is bubbly and the crisp topping is golden (add time, if needed).

Step 8

Remove from the oven and let the fruit crisp rest for 10-15 minutes before serving (the fruit layer will thicken as it cools). Serve warm or at room temperature with ice cream (or lemon frozen yogurt!) or sweetened, whipped cream, if desired.
