blueberry muffins open on a plate

What’s a blueberry muffin without a crumble topping, am I right? These blueberry protein muffins are super easy to make with Proteinfull Baking’s Classic Yellow Cake Mix, and the gluten-free crumble topping takes it over the top. So good!

The recipe book you see here is free with your first purchase of Proteinfull Baking’s cake mix. You can also preview a digital version of the recipe book.

Because we are adding blueberries to the cake batter, we’re going to use slightly less water than usual. The blueberries (or any added fruit) will release moisture into the cake, and we want to account for it. One half cup water does the trick!

The crumble topping is easy to make and adds just the right amount of flavor and texture. We’re using almond flour, granulated erythritol, cinnamon, and a little butter. Yum!

There you have it! Blueberry protein muffins with crumble topping. Give them a try!
