Step 1 Blend up cereal in a blender or food processor to make a fine crumb. You should have about 2 cups blended.
Step 2 Stir honey and melted coconut oil into the cereal crumbs in a large bowl.
Step 3 Press the cereal into the bottom of a greased 9inch tart pan (One with a releasable bottom is easiest). Freeze for 15 minutes.
Step 4 Spread vanilla yogurt over the top of the crust, and to the edges of the crust. Freeze for 15 minutes. Top with desired berries. Freeze for another 5 minutes, then slice up and serve.
