Put your cake mix, pudding mix, yogurt, water, oil and 2 beaten eggs in a bowl and mix well
Spray your crock pot with cooking spray
Spoon your batter into your crock pot and spread evenly
Sprinkle white chocolate chips on top
Place 6-8 paper towels on top of your crock pot, cover and cook on high for 1.5-4 hours (times can vary greatly depending on your particular slow cooker, watch carefully the first time you make it to know how your slow cooker cooks this cake)
Once your cake passes the toothpick test, remove the lid and let it cook for 15-20 minutes
Mix together your cream cheese and butter
Add in your milk, vanilla and stir well
Slowly stir in your powdered sugar (you can use less or more powdered sugar to reach the consistency of icing you desire)
Spread icing on top of the cooled cake and spoon into bowls to serve
I tried this recipe a couple different times before I got it right. On my first try, I used Cassie (my 9 x13 casserole slow cooker made by Crock Pot) and tried doing a cream cheese swirl. It didn't set up well. The edges were overdone while the middle wasn't done. So, I went back to the drawing board. I changed the recipe a bit and made a cream cheese icing instead of a cream cheese swirl...and voilà! You have this deliciously rich Crock Pot Strawberry Vanilla Spoon Cake!
Instead of sour cream in this cake, I gave Greek yogurt a try. It worked perfectly. However, if you have sour cream on hand, but not Greek yogurt, you can substitute your sour cream. I haven't tried sour cream with this Crock pot Strawberry Vanilla Spoon Cake, but it worked really well with my Crock Pot Vanilla Sour Cream Cake (which is what this recipe is based on).
I ended up using Sir Hamilton (my Hamilton Beach Programmable Insulated Slow Cooker) for this recipe, and he did an awesome job. You can use your favorite 6-quart crock pot if you don't have your own Sir Hamilton yet. You may need to turn your insert if one side of your crock cooks hotter than the other (kinda like when you turn your cake pan in your oven).
As with any of our recipes, calorie counts and nutritional information varies greatly depending on which products you choose to use when cooking this dish.
All slow cookers cook differently, so cooking times are always a basic guideline and should always be tested first in your own slow cooker and time adjusted as needed.
