In a large bowl, whisk the eggs, yogurt, sour cream, vanilla and cinnamon together. Gradually whisk in milk and maple syrup until blended.
Place half the bread in a greased 5- or 6-quart slow cooker (we used coconut oil to grease pan), layer with half of the blueberries, cream cheese and egg mixture. Repeat layers. Cover and refrigerate overnight.
Remove from fridge about 30 minutes before cooking. Cover and cook on low for 3-4 hours or until a knife is inserted into French toast and it comes out clean.
Enjoy. We didn’t even put syrup on ours.
