I grew up as a kid eating sourdough pancakes with frozen strawberry jam, so my idea was a twist on those flavors.
For the actual cake I just used a local mix from whole foods but to get the sourdough flavor I added two large scoops of greek yogurt. You can test out your batter raw and see if you want more or less, but remember the sweetness comes with the sauce.
The sauce - So I don't have a blender unfortunately ha but any mixer will work for this, I used a magic bullet. I put in a random amount of strawberries, I filled the cup a little over 1/3 of the way. Then I added 2 table spoons of real Maple syrup and then 1 large scoop may be even two of the greek yogurt. Put it all in and blend it up for some strawberry deliciousness.
Pour of that on top of your cakes, sprinkle some raw coconut shavings and you are good to go.
