What Are Oatmeal Crumble Bars?

Imagine a buttery, crumbly topping layered over a chewy oat base with juicy blueberries mixed in. That’s pretty much what oatmeal crumble bars are—an irresistible combo of oats, fruit, and a touch of sweetness. Think of them as a portable, handheld version of blueberry crisp, but way easier to make. Perfect for breakfast, a snack, or even dessert if you’re feeling fancy!

I personally love how versatile these bars are. You can swap out blueberries for raspberries, apples, or even chocolate chips if you’re feeling wild. Plus, they store well, so you can make a batch on Sunday and enjoy them all week. Who doesn’t love that?

Ingredients You’ll Need

Here’s where the magic begins. Gather these simple ingredients, and you’re almost there:

• 2 cups rolled old-fashioned oats
• ¼ cup pure maple syrup
• 1 teaspoon baking powder
• 1 ½ teaspoons ground cinnamon

How To Make Oatmeal Crumble Bars — Step by Step

Alright, grab your apron, and let’s get baking! I promise, this is easier than it sounds.

Step 1: Preheat and Prepare

Set your oven to 375°F (190°C). Spray an 8-inch square baking dish with cooking spray—no sticking, no fuss. This is your canvas.

Step 2: Make the Oat Base

In a large bowl, combine the oats, baking powder, cinnamon, and salt. I like to give it a good stir to distribute everything evenly.

Step 3: Mix the Wet Ingredients

In a separate small bowl, whisk together the almond milk, maple syrup, flaxseed (or egg), melted coconut oil, vanilla, and mashed bananas. This mixture will be the glue that holds everything together.

Step 4: Combine and Fold in Blueberries

Pour the wet mixture into the dry ingredients. Stir until well combined. Gently fold in 1 cup of blueberries. I love the burst of fruit flavor in every bite!

Step 5: Pour and Top

Carefully pour the batter into your prepared baking dish. Use a spatula to spread it evenly. Then, scatter the remaining blueberries across the top. Don’t be shy—more blueberries mean more flavor!

Step 6: Bake to Perfection

Pop it in the oven for about 40 to 55 minutes. You want the top to be golden and the middle to be set. If the edges start to brown too quickly, tent the top with foil. Patience is key here, so resist the urge to open the oven too often.

Step 7: Cool and Serve

Once baked, let your bars cool for about 10 minutes. Then, cut into squares and serve with a dollop of nut butter or a drizzle of maple syrup if you like things extra sweet. FYI, they taste amazing warmed up too!

Tips for Perfect Oatmeal Crumble Bars

• Don’t overmix: When combining wet and dry, mix just until incorporated to keep the bars tender and crumbly.
• Use ripe bananas: They add sweetness naturally and help bind everything together.
• Custom fruit: Feel free to swap blueberries for raspberries, sliced strawberries, or even chopped apples.
• Add nuts: For extra crunch, toss in some chopped walnuts or pecans into the crumble topping.
• Adjust sweetness: If you prefer sweeter bars, drizzle with honey or add a little more maple syrup.
