  • 4 cups mixed berries I used 1 lb. strawberries, chopped and 1 pint blueberries
  • 1/2 lb. chopped rhubarb 2 cups
  • 1 cup coconut sugar divided*
  • 1 1/2 tablespoons cornstarch
  • 2 tablespoons orange juice
  • 1 tablespoon orange zest
  • 1 cup old fashioned rolled oats
  • 1 cup all purpose flour
  • 1/2 cup melted coconut oil
  • 1 teaspoon ground cinnamon
  • pinch of salt


  • Spray the inside of the crock pot with cooking spray.  Add the berries, rhubarb, 1/2 cup of coconut sugar, cornstarch, orange juice and zest, and stir to combine.
  • In a medium bowl, combine the oats, flour, remaining coconut sugar, cinnamon, and pinch of salt until combined.  Add the coconut oil and stir until moistened.
  • Sprinkle the crisp topping evenly over the fruit mixture and cover.  Cook on low for 3-4 hours.  Serve warm and enjoy!


  • I noticed during the cooking time that one side of my crisp was cooking more than the other so I rotated the slow cooker pot so that the crisp would cook more evenly.  All slow cookers are different but this is something to look out for!
  • The coconut oil in the crumble gives it an amazing texture and flavor and I use it over butter all the time.  If you don't have coconut oil you can substitute it with the same amount of butter.
  • The coconut sugar may be substituted with the same amount of granulated or brown sugar.
  • Any combination of berries will do here, and if you're not into rhubarb, substitute it with the same amount of berries.
  • This crisp isn't overly sweet, so if you prefer a sweeter dessert, you can add an additional 2-4 tablespoons more sweetener.
