Blueberry Peach Crumble

It’s also a lifesaver for busy weeks—because it looks impressive, but it’s secretly low-stress. (My favorite kind of magic.)

Why You’ll Love This Blueberry Peach Crumble

• No crust drama. Crumble topping = effortless and forgiving.
• Perfect for picky eaters. Fruit + cinnamon-sugar topping is basically dessert diplomacy.
• Flexible and cozy year-round. Summer peaches? Amazing. Slightly sad grocery store peaches in winter? Still delicious once they’re baked and bubbly.

Ingredients You’ll Need

For the filling

• 2 cups blueberries
• 2 1/2 cups peeled and sliced peaches (about 5–6 peaches)
• 1 tablespoon fresh lemon juice
• 1 teaspoon lemon zest
• 1/4 teaspoon vanilla extract
• 1/2 cup granulated sugar
• 1/4 cup all-purpose flour

For the crumble topping

• 1/2 cup all-purpose flour
• 1/2 cup old-fashioned oats
• 1/3 cup brown sugar
• 1/4 cup granulated sugar
• 1/2 teaspoon salt
• 1 teaspoon ground cinnamon
• 6 tablespoons cold butter, diced

How to Make Blueberry Peach Crumble (Step-by-Step)

1) Preheat and prep

Preheat your oven to 350°F. Grab a 2-quart baking dish (ceramic or glass is great) or a large cast iron skillet.

2) Mix the fruit filling

In a large bowl, combine:

• blueberries
• sliced peaches
• lemon juice + lemon zest
• vanilla extract
• granulated sugar
• flour

Gently toss until everything is coated. Then let it sit while you make the topping.

Why the waiting helps: The sugar starts pulling out juices, and the flour begins working on thickening. Basically, your filling gets its act together.

3) Combine the dry topping ingredients

In another bowl, whisk together:

• flour
• oats
• brown sugar
• granulated sugar
• salt
• cinnamon

4) Add the butter (aka the crumble magic)

Add the cold diced butter to the bowl. Use your fingers to work it into the dry mixture until you get big crumbles.

Texture goal: Some pea-sized bits, some larger chunks. Those butter pieces melt in the oven and turn into crispy, golden, buttery pockets. (Yes please.)

5) Assemble

Try not to press it down too much—you want those crags and mountains on top. Crumble is not a “smooth it out” situation. Let it be wild and beautiful.

6) Bake (with spill protection!)

Place the dish on a large baking sheet and bake for 40–45 minutes, or until:

• the topping is browned and crisp
• the fruit juices are bubbly

7) Cool a bit

8) Serve like you mean it

Serve warm or at room temp. And if you’re on Team Ice Cream (I am), add a scoop of vanilla ice cream and watch it melt into the crunchy topping like it was born for this moment.

Aneta’s Cozy Kitchen Tip Corner

• Use cold butter. Warm butter makes a paste. Cold butter makes crumbles. Crumbles = happiness.
• Want extra crunch? Add 2 tablespoons more oats. Your topping will be slightly more rustic and hearty.
• If your topping browns too fast, loosely cover with foil for the last 10 minutes. (Nobody likes a burnt crumble… except maybe your smoke detector.)

And don’t worry if the filling looks like a hot purple lava situation when it comes out. That bubbling is the good stuff.

A Little Personal Note From My Kitchen

This Blueberry Peach Crumble became one of my go-to desserts the first time I made it for a “casual” family get-together that turned into a full-on crowd. I needed something easy, fast, and not fussy—because I was already juggling a million things (and, honestly, I didn’t feel like rolling dough and pretending it was relaxing).

FAQs About Blueberry Peach Crumble

Can I use frozen blueberries or frozen peaches?

Yes! Frozen blueberries work great. For frozen peaches, it also works—just expect a juicier filling. You can add an extra tablespoon of flour to help thicken. Bake time may need a few extra minutes.

Do I have to peel the peaches?

You don’t have to. The skins soften as they bake, and some people like the texture. If you want the smoothest, most classic crumble, peel them.

How do I store leftovers?

Can I make Blueberry Peach Crumble ahead of time?

Yes. You can assemble it, cover, and refrigerate for a few hours before baking. If it’s cold going into the oven, add a few minutes to the bake time.

What’s the best way to keep the topping crispy?

Oven reheat is your best friend. The microwave makes it soft (still tasty, just less crunchy).
