Crumble You Eat With Your Hands

I adore a fresh fruit crumble, crisp, or cobbler in the summer. Whether it’s a Blueberry Almond Crisp or a Fresh Peach Crumble or Snickerdoodle Peach Cobbler, I cannot get enough. These bars taste just like a fruit crumble, but in a delicious bar form. By itself or with a scoop of ice cream, that sweet juiciness is hard to beat.

My Favorite Summer Fruits

I know it’s super hot outside, but I just can’t stop baking so I usually sweat it out or crank the A/C because all these yummy ideas I have in my baking brain are not gonna wait and some of the most delicious fruits are at their peak during this summer heat!

Two of my absolute favorite fruits are peaches and raspberries and when you put them together they’re something special! I’m always throwing some raspberries over a sliced peach in a bowl for a fresh and refreshing summer snack! Sometimes I’ll bake up a simple streusel to throw on top. So I thought why not bake them into a treat that’s light enough to eat in this crazy summer heat. And they are AMAZING.

Ingredients and Supplies

(see recipe card at the bottom of this post for measurements and details. To learn more about specific baking ingredients and how they function in baking recipes, reference my Complete Guide to Baking Ingredients)

Ingredients:

Fresh raspberries: provide tartness and a wonderful flavor contrast to the peaches. Use fresh for best texture, but frozen (unthawed) raspberries would work too. Just increase the cornstarch slightly as frozen fruit releases more juice. Blackberries, blueberries, or chopped strawberries can be substituted, if desired.
Fresh peaches (chopped): add sweetness, moisture, and a soft, juicy texture. To peel easily, blanch peaches in hot water for 30–60 seconds, then slip off the skin. Nectarines (no peeling needed), apricots, or mango can be substituted, if desired.
Cornstarch: thickens the fruit juices as the bars bake. Mix thoroughly with the sugar to avoid clumps.
All-purpose flour: provides structure for the crust and crumble. Whole wheat flour or a gluten-free flour blend can be substituted, if necessary.
Old-fashioned oats: adds texture and chewiness to the crust and crumble. Avoid quick oats as they’ll make the crumble too soft.
Granulated sugar: sweetens the filling and helps draw juices from the fruits while also sweetening the crust and crumble topping to create the crisp texture as it bakes.
Light brown sugar: adds moisture and chewiness due to the molasses content. If you use dark brown sugar, the crust and topping will have a richer molasses flavor.
Cinnamon: warms up the flavor and especially complements the peaches.
Kosher salt: balances the sweetness and enhances the overall flavor. Table salt will actually pack a saltier punch than Kosher salt so if you only have table salt, adjust accordingly.
Unsalted butter: binds the crust/crumble and adds richness. If you use salted butter, you might consider using less salt in the recipe as it will affect the sweetness.
Large egg: binds all the ingredients in the crust and gives slight structure.
Vanilla extract: adds depth and enhances sweetness of the crust and topping.

How to Make Peach Raspberry Crumb Bars

Preheat oven to 350°F. Lightly grease a 13×9-inch baking dish with non-stick cooking spray and set aside.
Make the fruit filling: In a large bowl, add the raspberries and chopped peaches.
In a small bowl, whisk together the sugar and cornstarch. Sprinkle the sugar mixture over the fruit and stir until the fruit is lightly coated.

Steps to make Peach Raspberry Crumb Bars

Set aside.
Make the crust mixture: In another large bowl, whisk together the flour, oats, granulated sugar, brown sugar, cinnamon and salt.
Make a well in the center and add the melted butter, beaten egg and vanilla.

Stir until well combined.
Press two-thirds of the crust mixture evenly into the bottom of the prepared baking dish.
Spread the fruit mixture evenly over the crust.
Crumble the remaining crust mixture evenly over the top of the fruit.

Bake for 40-45 minutes or until the fruit is bubbling and the crumbs on top start to brown. Let cool completely in the baking dish before cutting into squares. Store in the refrigerator.

Storage

Store the bars in an airtight container in the refrigerator for up to 5 days. Enjoy chilled or let set at room temperature for 10-15 minutes before serving for best texture. You could also warm them slightly in the oven or toaster oven for a crispier top.

To freeze: place the bars in a single layer on a parchment-lined baking sheet and freeze until solid, about 1–2 hours. Wrap each frozen bar in plastic wrap and place them in a freezer-safe container or plastic bag to freeze for up to 2 months. Thaw overnight in the fridge.
