Fresh blueberries and peaches go together perfectly in these delicious Blueberry Peach Crumb Bars! A sweet and crumbly oat mixture is layered around the fruits for a treat that is delicious served cold or warmed up and topped with vanilla ice cream.

There’s nothing like a ripe, juicy peach! And they are so yummy in crumb desserts like this one. Pair them with fresh blueberries and you have these tasty Blueberry Peach Crumb Bars.
My brother and his in-laws have a gorgeous farm in North Carolina, Jeter Mountain Farm. This summer they have had u-pick peaches and they sent me a basket of them last week.
My kids are obsessed with fresh peaches so we’ve been eating lots of them for snacks, but I also had to make a few peach desserts like these bars.

To make these Blueberry Peach Crumb Bars, you’ll start by making an easy crumb mixture of butter, flour, oats and a few other simple ingredients.
Then you’ll mix the peeled and diced peaches with the blueberries and some sugar, cornstarch and lemon juice to make the filling.
Press some of the crumb mixture into the pan and top with the filling. Then use the remaining crumbs to top the bars before baking.

Can I use other fruits in these bars?
I think the combination of blueberries and peaches in these bars is SO GOOD but yes, you could definitely switch out one or both of the fruits for something else if you like. Strawberries, raspberries, blackberries, pears or cherries would be good options.
Can I use frozen or canned fruit in these bars?
I recommend using fresh fruit if you can because it is so flavorful and delicious in these bars! But in a pinch you could use canned or frozen. If using canned peaches, drain them before adding them to the mixture. If using frozen peaches or blueberries, thaw them first.

How to Easily Peel Peaches
Blanch peaches to make them peel easily. Bring a large pot of water to a boil. Fill a large bowl with ice and cold water, leaving room to add the peaches so it won’t overflow. Place 2-3 peaches into the water for about 30 seconds, then remove and place directly in the ice bath. Repeat for remaining peaches. The skins should easily loosen and peel off.
How to Serve and Store these Bars
To cut into neat squares like shown in the photos, you will need to let the bars cool completely. They can be stored in an airtight container in the refrigerator and eaten cold. They also taste delicious warm! You can eat them straight from the oven with vanilla ice cream, but they won’t cut as neatly when warm. Another option is to warm up the cooled and cut bars in the oven or microwave.

Blueberry Peach Crumb Bars
Fresh blueberries and peaches go together perfectly in these delicious crumb bars! A sweet and crumbly oat mixture is layered around the fruits for a treat that is delicious served cold or warmed up and topped with vanilla ice cream.
Ingredients
For the Crust
- 1 cup granulated sugar
- 2 1/2 cups flour
- 1 cup rolled oats
- 1 tsp baking powder
- 1/2 tsp salt
- 1/2 tsp cinnamon
- 1 cup butter, cold and cut into slices
- 2 large eggs, lightly beaten
- 2-4 tbsp milk
For the Filling
- 1/2 cup granulated sugar
- 1 tbsp cornstarch
- 1/2 tsp cinnamon
- 4 large peaches, peeled and diced (see notes for easy peeling instructions)
- 1 cup blueberries
- 1 tsp lemon juice
Instructions
Preheat oven to 350 F if using a glass pan, or 375 F if using a metal pan. Butter or spray a 9x13 inch baking pan and set aside.
For the Crust:
- In a medium bowl mix together the 1 cup of sugar, 2 1/2 cups of flour, oats, baking powder, salt and cinnamon. Using a pastry cutter, cut in the butter until the mixture resembles coarse sand. Add the lightly beaten eggs and add the milk a little at a time, stirring until the mixture is crumbly but begins to hold its shape.
- Gently press a little more than half of the dough into the prepared pan.
For the Filling:
- In a large mixing bowl, mix together the sugar, cornstarch and cinnamon. Add the diced peaches, blueberries and lemon juice. Toss to coat. Pour the fruit mixture on top of the crust and spread evenly.
- Using your hands, press together handfuls of the remaining crust mixture and crumble it over top of the fruit filling, leaving some some fruit showing through.
- If using a glass pan, bake at 350 F for 50-55 minutes or until lightly browned. If using a metal pan, bake at 375 F for 40-45 minutes. Cool completely before cutting into slices. These bars also taste delicious straight from the oven with vanilla ice cream! They won't cut as neatly if you cut them when warm, though. Store in an airtight container in the refrigerator.

Can you freeze these bars after making and serve later?

I’ve never tried freezing these bars, but I would assume it would work!
