Ingredients You’ll Need

This recipe is pretty straightforward, and most of these ingredients are staples in my pantry. Here’s what you’ll need:

• 2 cups rolled old-fashioned oats
• ¼ cup pure maple syrup
• 1 teaspoon baking powder
• 1 ½ teaspoons ground cinnamon
• ½ teaspoon sea salt
• 2 cups unsweetened vanilla almond milk
• 1 tablespoon ground flaxseed (or 1 large egg, if you’re feeling traditional)
• 2 tablespoons coconut oil, melted
• 2 teaspoons vanilla extract
• 2 ripe bananas, mashed
• 1 ¼ cups fresh or frozen blueberries, divided
• Additional blueberries, nut butter, and extra maple syrup for serving

FYI, I love tossing in frozen blueberries because they keep the bars nice and juicy, but fresh ones work just as well. Also, if you’re vegan or egg-free, ground flaxseed is your hero here.

How to Make Oat Crumble Bars (Step-by-Step)

Now, I promise, this isn’t going to be a complicated baking adventure. We’re talking about a straightforward, no-fuss process that even a beginner can conquer. Ready? Let’s do it.

1. Preheat and Prepare

Set your oven to 375°F (190°C). Spray an 8-inch square baking dish with cooking spray or line it with parchment paper—whatever makes your life easier.

2. Mix the Dry Ingredients

In a large mixing bowl, combine:

• 2 cups rolled oats
• 1 teaspoon baking powder
• 1 ½ teaspoons ground cinnamon
• ½ teaspoon sea salt

Stir these together until evenly distributed. This forms the base of your crumble and helps keep everything balanced.

3. Combine the Wet Ingredients

In a separate bowl, whisk together:

• 2 cups almond milk
• ¼ cup maple syrup
• 1 tablespoon ground flaxseed (or egg)
• 2 tablespoons melted coconut oil
• 2 teaspoons vanilla
• 2 mashed bananas

Mix until smooth and well combined. The bananas add sweetness and moisture, making these bars extra tender.

4. Bring It All Together

Pour the wet mixture into the dry ingredients. Stir gently but thoroughly until you get a thick, sticky batter. Fold in 1 cup of blueberries carefully so they don’t get smashed. This way, you’ll get gorgeous pops of color and flavor in every bite.

5. Bake to Perfection

Pour the batter into your prepared baking dish. Use a spatula to spread it evenly. Scatter the remaining ¼ cup of blueberries across the top—because more blueberries are always a good idea.

Bake for about 40 to 55 minutes. The bars are done when the top turns golden brown and the center is set. If you stick a toothpick in the middle and it comes out clean, you’re golden.

6. Cool and Serve

Let the bars cool for at least 10 minutes. This helps them firm up so they don’t fall apart when you cut them. Slice into squares, and if you’re feeling fancy, top with a dollop of nut butter and a drizzle of extra maple syrup.

Storage Tips: Keep Them Fresh

Here’s the scoop on storing these tasty bars:

• Refrigerate: Store in an airtight container for up to 5 days. Trust me, they taste even better the next day—like a cozy hug in snack form.
• Freeze: Wrap individual bars in plastic wrap or foil, then pop them into a freezer-safe container. They’ll stay good for up to 3 months. To reheat, microwave for about 30 seconds or warm in the oven at 350°F for 10 minutes.
• Reheat tips: If you want to enjoy warm, gooey bars, just microwave or pop them in a toaster oven for a few minutes. They’ll feel like freshly baked every time.

Customization Ideas: Make Them Your Own

Feel like switching things up? Absolutely! Here are some ideas to make these oat crumble bars even more awesome:

• Add nuts: Chopped walnuts or pecans add crunch.
• Swap the fruit: Raspberries, sliced strawberries, or chopped apples work beautifully.
• Layer in chocolate chips: Because who doesn’t love a little chocolate?
• Top with yogurt or more fruit: For extra creaminess and freshness.
• Use different sweeteners: Honey, agave, or brown sugar can replace maple syrup.

Don’t hesitate to experiment—I do it all the time, and honestly, that’s what keeps these bars exciting.
