Ingredients You’ll Need for Blueberry Almond Crumble Bar

Get ready to raid your pantry, because odds are you already have most of this stuff:

All-purpose flour – the foundation, aka the glue that holds it all together.
Rolled oats – for that perfect crumbly texture.
Brown sugar – because life’s too short for boring white sugar alone.
Unsalted butter – melted, golden, and the reason these bars taste like heaven.
Almonds (chopped) – for crunch and to make you feel fancy.
Fresh or frozen blueberries – the star of the show. (Frozen = lazy person’s dream.)
Granulated sugar – sweetens up those berries.
Cornstarch – thickens the blueberry filling so it doesn’t turn into soup.
Vanilla extract – because everything tastes better with a splash of vanilla.
Pinch of salt – balances the sweetness and keeps it real.

Step-by-Step Instructions

Preheat your oven to 350°F (175°C). Yes, you actually have to do this. Cold ovens ruin lives.
Make the crumble mix: In a bowl, mix flour, oats, brown sugar, melted butter, almonds, and salt. Stir until crumbly.
Press the base: Take about two-thirds of the crumble mix and press it firmly into a greased baking pan. Don’t stress if it’s uneven; rustic is chic.
Whip up the blueberry filling: Toss blueberries with sugar, cornstarch, and vanilla. Try not to snack on them all.
Assemble the bars: Spread the blueberry mixture over the crust, then sprinkle the remaining crumble mix on top.
Bake for about 35–40 minutes, until golden brown and bubbly. (If your kitchen smells amazing, you’re on the right track.)
Cool before slicing: Yes, I know it’s hard. Hot blueberry lava burns are not cute.

Common Mistakes to Avoid

Skipping the cornstarch: Unless you enjoy blueberry soup bars, don’t do it.
Not pressing the crust firmly: Crust that crumbles apart = dessert sadness.
Cutting too early: Patience, my friend. If you slice while hot, you’ll get a gooey mess instead of neat bars.
Thinking almonds are optional: They’re not. Okay, technically they are—but don’t blame me if your bars taste boring.

Alternatives & Substitutions

Blueberries → Swap with raspberries, blackberries, or even diced apples. Basically, any fruit that doesn’t run away works.
Almonds → Walnuts, pecans, or even sunflower seeds (if you’re nut-free).
Butter → Coconut oil if you’re going dairy-free, but IMO, butter is life.
Brown sugar → You can use coconut sugar or white sugar, but the flavor won’t be as rich.
Oats → If you hate oats (who hurt you?), just use extra flour.

FAQS about Blueberry Almond Crumble Bar
