Step 1

Place berries in your pin pan. Pour sugar over the berries, and sprinkle lemon zest and vanilla on top.

Step 2

Place the oatmeal, flour, and brown sugar into a bowl. Mix to evenly distribute them. Put diced butter into the bowl and use a pastry blender or your hands to combine until the mixture is crumbly.

Step 3

Spread the mixture evenly over the berries, and bake at 350 for 40-50 minutes, or until the mixture is bubbly, delicious, and the top is golden brown.
