Apple Cinnamon Oatmeal Breakfast Bars

There’s something so comforting about the smell of baked apples and cinnamon filling the kitchen. These Apple Cinnamon Oatmeal Breakfast Bars are like a warm hug in breakfast form — soft, hearty, and perfectly spiced. I love making a batch at the beginning of the week so we have a quick, nutritious breakfast or snack ready to go. They’re family-friendly, husband-approved, and make busy mornings feel a little more intentional (and delicious).

Apple cinnamon oatmeal breakfast bars are like dessert for breakfast but are gluten-free, dairy-free, and high in protein. You will love how easy these bars are to meal prep for a week of healthy breakfast or snacks! 

• Apple Cinnamon oatmeal breakfast bars are an easy way to prep breakfast or snacks for the week
• They’re high in protein from collagen and vanilla protein powder.
• Naturally sweetened with applesauce and fruit — no refined sugar needed.
• Perfect for meal prep — bake once, enjoy all week.
• Can be enjoyed warm, cold, or topped with yogurt for a filling breakfast.
• Baked oat breakfast bars are gluten-free, dairy-free, and plant-based
• An easy grab-and-go breakfast or snack option

• Oats: A complex carbohydrate rich in soluble fiber that helps keep you full, supports digestion, and can help balance blood sugar.
• Apple: Adds natural sweetness and fiber, making these bars perfectly sweet without any added sugar.
• Applesauce: Enhances the apple flavor and keeps the bars soft and moist.
• Coconut Oil: A healthy fat with medium-chain fatty acids that provide energy and help you feel satisfied.
• Eggs: Bind the ingredients together and add protein. (I haven’t tested with flax or chia eggs, so I can only vouch for the real ones!)
• Collagen Peptides: A great source of protein that may support skin, hair, joint, and gut health.
• Vanilla Protein Powder: Boosts the protein content to help keep blood sugar steady and energy levels balanced.
• Cinnamon: Adds cozy flavor while offering antioxidant and blood sugar–balancing benefits.
• Plant-Based Milk: Use your favorite — almond, cashew, oat, or hemp milk all work beautifully.
• Walnuts or Pecans (optional): Add a little crunch and healthy fats for extra texture and flavor.

1. Preheat oven to 375°F and line a 9×7 or 8×8 pan with parchment paper.
2. Melt the coconut oil.
3. In a high-speed blender, combine all ingredients except the apple and nuts. Blend until smooth.
4. Chop the apple into small pieces and stir it into the batter.
5. Pour into the lined pan and top with walnuts or pecans if using.
6. Bake for 35–40 minutes, until golden brown.
7. Check doneness with a toothpick — a few moist crumbs are perfect; it shouldn’t be raw in the center.
8. Let cool before slicing

Top with a dollop of yogurt mixed with vanilla protein powder and a drizzle of nut butter for extra creaminess and flavor.

• Oats: Use quick oats if that’s what you have, but rolled oats give the best texture.
• Milk: Any milk will do — almond, oat, or regular dairy milk.
• Coconut oil: Can substitute with melted butter or avocado oil.
• Apple: Try swapping with pear or adding raisins for variety.

• Different protein powders absorb liquid differently if it is too thick add more milk
• Blend the batter just until smooth — don’t overblend.
• Let bars cool completely before cutting for clean slices.
• Line the pan with parchment for easy removal.
• If you do not have a high-powered blender first add the oats and blend till they make a flour. Then add collagen peptides, vanilla protein, baking powder, salt, and cinnamon and blend. Lastly, add in coconut oil milk, and eggs and blend till combine

These bars are soft, moist, and slightly chewy — somewhere between a baked oatmeal and a blondie. The apple pieces give juicy bursts of flavor, while the cinnamon adds that cozy fall warmth. They’re not overly sweet, making them perfect for breakfast or an afternoon snack.

• Serve: Warm with yogurt mixed with vanilla protein and a little drizzle of nut butter, or grab cold straight from the fridge for a quick bite.
• Store: Keep in an airtight container in the fridge for up to 5 days.
• Freeze: Wrap individually and freeze for up to 2 months. Reheat in the microwave for 20–30 seconds.
