Another great idea submitted by a reader, Protein Coffee Cake with Crumble Topping! A remake of the traditional, unhealthy packaged coffee cake treat. Now, a high-protein, gluten-free version!

To make the crumble topping here, I adapted an idea I found on the Daily Dietribe. This Protein Coffee Cake with Crumble Topping recipe uses Quest Multi-Purpose Protein Powder, and I added a Cinnamon Roll Quest Bar to the crumble topping. The result? Delicious!

Quest Protein Powder is a whey/casein blend. The casein acts like a flour when baking, so a whey protein wouldn’t be a great substitute here. You’d have to add in some extra flour, and then check that your liquid is still enough for a cake batter consistency. Easier to get yourself some Quest Multi-Purpose Protein Powder! It’s great for baking; I’ve used it here a bunch!

  • 1 teaspoon Paige's vanilla (5ml)
Crumble topping:
  1. Preheat oven to 325F (163C).
  2. Mix dry ingredients for the cake batter to combine.
  3. Add almond milk and vanilla. Mix well.
  4. Spoon into three large silicone muffin cups. Set aside.
  5. Mix the stevia, cinnamon, and Brown Rice Powder to combine.
  6. Add coconut oil. Mix well.

A note about substitutions: Quest powder is a whey/casein blend, so I would only recommend using other whey/casein blends as a substitute. Other types of protein powder will bake differently. (See my Recipe Basics video for examples of what goes wrong when you use the wrong protein powder.)
