CINNAMON SWIRL PROTEIN BREAD
This sweet and delicious cinnamon swirl bread packs a satisfying 20 grams of protein per serving, making it a perfect choice for fueling your day or recovering after a workout. Its soft, tender crumb is infused with warm cinnamon and a sweet swirl that creates a delightful contrast in both texture and flavor—crispy edges give way to moist, fluffy interior with each bite. The rich, comforting aroma of cinnamon hints at the cozy, indulgent taste, while the balanced macros support muscle repair and sustained energy. Ideal for meal prep, enjoy this bread toasted with a smear of almond butter or alongside your morning coffee, or slice it up for a nutritious snack on-the-go. For those with dietary preferences, this recipe can easily be made gluten-free using a gluten-free flour blend, and vegan versions can be achieved with plant-based protein sources and dairy-free milk. For best results, ensure the dough is well-kneaded to develop the gluten structure, and don’t overbake—just until golden—to keep it moist and tender. Whether you’re looking to satisfy a sweet craving or add a high-protein option to your meal lineup, this cinnamon swirl bread is a versatile and tasty choice that supports your fitness goals without compromising on flavor.

INGREDIENTS
- 120g vanilla whey protein powder
- 100g oat flour
- 3 large eggs
- 120ml milk
- 60g sweetener (e.g., erythritol)
- 1 tsp baking powder
- For the swirl: 2 tbsp cinnamon, 2 tbsp sweetener
STEP-BY-STEP INSTRUCTIONS
Preheat Oven
Preheat oven to 350°F (175°C). Grease a loaf pan.
Prepare Batter
In a large bowl, mix together the protein powder, oat flour, eggs, milk, sweetener, and baking powder.
Create Swirl
In a small bowl, mix the cinnamon and sweetener for the swirl.
Layer and Swirl
Pour half of the batter into the loaf pan. Sprinkle the cinnamon mixture over the top. Pour the remaining batter over the cinnamon layer. Use a knife to gently swirl the layers.
Bake
Bake for 25-30 minutes, until a toothpick comes out clean.
Cool
Let the bread cool before slicing.
TROUBLESHOOTING GUIDE
Slice is too dry
Try reducing baking time by 2-3 minutes, or add an extra tablespoon of Greek yogurt to the batter.
Not rising properly
Check that your baking powder is fresh (less than 6 months old). Also avoid overmixing the batter.
Gummy texture in center
This usually means under-baking. Use a toothpick to test - it should come out with just a few moist crumbs.
Too dense
Make sure you're measuring protein powder correctly. Too much protein powder can make baked goods dense.
