Why This Recipe Stands Out

It’s that time of year when the best fruits ripen, and these Peach Blueberry Crumb Bars are the perfect dessert:

  • Perfect Use of Fruit: These bars help us avoid wasting any fruit that’s ripening faster than we can eat it. In fact, slightly overripe fruit is perfect for this recipe.
  • Great for Potlucks: Dessert Bar Recipes are our go-to potluck treat to pass around and these Crumb Bars are no exception!
  • The Buttery Crust: Nothing beats the homemade buttery crust in this recipe. It reminds us of our favorite flaky butter crust that we use in our Apple Pie Recipe.
  • Perfect for Meal Prep: Peach Blueberry Crumb Bars make the perfect prep-ahead recipe that can easily double as a breakfast. They freeze wonderfully!

Key Recipe Ingredients

fresh blueberries for blueberry pie and blueberry bars.

Dough Ingredients

  • Salted Butter – Very cold butter makes for the flakiest, melt-in-your-mouth crust.
  • Granulated Sugar – Plain sugar is all that’s needed to sweeten the crust perfectly.
  • Egg – The egg helps hold the crust together and gives it the perfect golden tint.

Filling Ingredients

  • Peaches – Peeled and sliced peaches cook into the perfect soft, caramelly center.
  • Blueberries – Fresh blueberries add splashes of bright purple to these bars making them not only delicious, but beautiful.
  • Lemon Juice – A little bit of lemon juice provides the perfect touch of acidity to balance the sweetness of the fruit.
  • Spices – Cinnamon and nutmeg bring warm, earthy flavors that balance the light, fresh flavors.

Topping Ingredients

  • Brown Sugar – Brown sugar melts over top of these bars creating the perfect ooey-gooey, caramelly topping.
  • Pecans – Chopped pecans toast in the oven bringing a bit of nutty crunch to Peach Blueberry Bars.

Commonly Asked Questions

How long do Peach Blueberry Crumb Bars last?

Peach Blueberry Crumb Bars keep well in an airtight container in the fridge for up to 3 days. They also freeze super well! Crumb bars will stay fresh for months in the freezer. We like wrapping the squares individually for easy thawing.

Can I make these gluten-free?

These bars should work just fine gluten-free if you replace the all-purpose flour with 1:1 gluten-free all-purpose flour.

Can I use frozen berries for this recipe?

Yes! While we prefer fresh berries, you can definitely still use frozen if that’s all you have on hand. Use them frozen; do not thaw. Baking may take longer when using frozen berries.

How can I tell when my crumb bars are done?

You’ll know your crumb bars are done when the crumble turns golden and the filling starts to bubble on the edges. It should take 45-60 minutes.

Can I use other kinds of fruit in this recipe?

Absolutely! These crumb bars work amazingly with most any kind of fruit and berry.

Ingredients  

For the Dough:

For the Filling:

For the Topping:

  • 4 TB packed brown sugar
  • ½ cup chopped pecans

Instructions

  • Preheat oven to 375F, with rack on middle position. Generously grease a 9×13 inch pan, and set aside.
  • For the Dough: In a large bowl, whisk together the flour, sugar, baking powder, and salt. Cut in the cold butter with a pastry cutter. Add the lightly beaten egg. Dough will be moist and crumbly, like clumpy wet sand. Firmly press half of the dough into well-greased pan. Place in fridge while you make topping.
  • For the Topping: Add 4 TB brown sugar and 1/2 cup chopped pecans to the remaining half of the dough. Mix together by hand. Place in fridge while you make filling.
  • For the Filling: In a large bowl, combine peaches and lemon juice. In another bowl, whisk together the flour, sugar, salt, cinnamon, and nutmeg. Gently fold flour mixture together with the peaches.
  • Spread peach mixture evenly over the chilled crust. Sprinkle blueberries over the peaches. Crumble the chilled topping over the filling.
  • Bake for 45-60 minutes, or until top is golden brown. If top is getting too browned, you can cover loosely with foil for awhile during baking. If it is not browned enough, finish baking on upper middle rack.
  • Cool completely on wire rack. Chill in fridge, uncovered until ready to cut and serve. It will be easier to cut when chilled.
  • Serve with fresh whipped cream, ice cream, or a good cup of coffee.

Notes

  • Keep and eye on the crumb bars as they bake. If the top is getting too brown, you may need to tent some foil on top to allow the center to keep cooking without the top getting too crisp.
  • Make sure to let bars cool completely before cutting. It’s worth the wait!
  • Serve Peach Blueberry Crumb Bars with a scoop of Easy Vanilla Ice Cream and dollop of Stabilized Whipped Cream.

    I am looking forward to making these – but I have a question! How thin do you slice your peaches? When I’ve made peach bars in the past, it was really easy for the peaches to sort of disintegrate a bit while baking, and those have always been diced. So just curious if you have a standard you go by to avoid this! Thanks!

      • Amy Dong

      Great question, Sarah! I slice about 1/4″ thick. Hope you love these! 🙂

    • Eva

    Hi-really want to make these but can only get frozen blueberries. Will that still work?

      • Amy Dong

      Eva, you can use frozen blueberries – gently fold them in still frozen; do not defrost them. Enjoy!

    • A. M. Brown

    Yes, they freeze well, I’ve frozen half a batch every year for the last 3 years. Taste just as delish after thaw- Yum!
