How to Make Apple Crumble Bars: Step-by-Step

Now, the fun part — baking! Follow these simple steps, and you’ll have a batch of irresistible apple crumble bars in no time.

Save for later

Step 1: Preheat and Prep

Preheat your oven to 375°F (190°C).
Spray an 8-inch square baking dish with cooking spray or line it with parchment paper for easy removal.

Step 2: Mix the Dry Ingredients

In a large mixing bowl, combine the oats, baking powder, cinnamon, and sea salt.
Give this a good stir so everything gets evenly coated. I like to do this first because it sets a solid flavor base.

Step 3: Combine the Wet Ingredients

In a separate smaller bowl, whisk together the almond milk, maple syrup, ground flaxseed (or egg), melted coconut oil, vanilla, and mashed bananas.
Whisk until smooth and well combined. This mixture is the glue that holds everything together.

Step 4: Mix Everything Up

Pour the wet mixture into the dry ingredients.
Stir well until all the oats are coated and you get a sticky, slightly chunky batter.
Gently fold in 1 cup of blueberries. I love how the berries burst during baking, adding lovely pockets of flavor.

Step 5: Assemble and Top

Transfer the batter into your prepared baking dish.
Use a spatula or your hands to press it evenly into the dish.
Scatter the remaining blueberries across the top, pressing them lightly into the batter. This creates that gorgeous, juicy look.

Step 6: Bake and Wait

Pop your dish into the oven and bake for 40 to 55 minutes.
You’re looking for a golden top and a set middle. The longer you bake, the firmer it gets, so keep an eye on it.
Once done, let it cool for about 10 minutes. I know, patience is hard, but it’s worth it!

Step 7: Serve and Enjoy

Slice into squares or bars.
Top with a dollop of nut butter, an extra drizzle of maple syrup, or more blueberries if you’re feeling fancy.
Trust me, every bite is pure heaven.

Tips for Customizing Your Apple Crumble Bars

Feeling creative? Here are some quick ideas:

Save for later

Add nuts: Chopped walnuts or pecans add crunch and richness.
Swap fruits: Pears or apples work beautifully too.
Make it gluten-free: Use certified gluten-free oats.
Make it vegan: Stick with flaxseed or a chia egg instead of eggs, and ensure your sweetener is pure maple syrup or agave.

How to Store Your Apple Crumble Bars

Because these bars are just that good, you’ll probably want to save some for later. Here’s how to keep them fresh:

Refrigerate: Store in an airtight container in the fridge for up to 5 days.
Freeze: Wrap individual bars in plastic wrap or foil, then place in a freezer-safe bag or container. They’ll last up to 3 months.
Reheat: To enjoy warm, reheat in the microwave for 20-30 seconds or in a 350°F oven for 10-15 minutes. They taste like freshly baked every time.

A quick note: If you keep them in the fridge, the bars firm up a bit, which is perfect if you prefer a more structured bite.

Final Thoughts: Your New Favorite Snack

There you have it! These apple crumble bars are the perfect mix of cozy, fruity, and crunchy. Whether you’re craving a sweet treat or a healthy-ish snack, they’ve got you covered. Plus, they’re super easy to make, so no excuses to not try them — trust me, your taste buds will thank you.
