Cinnamon Crumble Cake Bars

I am loving how these cake bars turned out - texurely, they're perfect. A soft, light cake topped with a sweet, buttery, and crunchy crumble topping. These are traditionally known as coffee cake bars. I understand why. Since the cake isn't overly sweet, it pairs nicely with a cup of coffee. I enjoyed mine with a cup of milk - basically, either way, you won't be disappointed! 


1½ cup Vitacost’s gluten-free baking flour
2 scoops ARO vanilla whey protein powder
¼ cup coconut sugar
2 teaspoons baking powder
1 teaspoon cinnamon
2 eggs
¼ cup cashew butter
¼ cup unsweetened applesauce
½ cup unsweetened coconut milk

1/3 cup coconut sugar
¼ cup ghee butter, melted
¼ cup Vitacost’s gluten-free baking flour
½ scoop vanilla protein powder

  1. Can I use oat flour? And any vanilla protein powder? TIA

    1. Yes, oat flour should work just fine. I recommend whey protein powder, then casein, then isolate. Hope this helps!

    2. Sure why protein powder will suit the most.
