Why This Recipe is a Winner

🌟 Pro Tips for Perfect Bars

A few simple tips will make all the difference in creating these beautiful and delicious bars.

• Use Cold Butter: This is the most important rule for the crisp. Using cold, cubed butter and cutting it into the dry ingredients is what creates that signature flaky, crumbly texture. If your butter is too warm, the dough will be greasy and the bars will be tough.
• Don’t Overmix: When you mix the crumble dough, be careful not to overwork it. Mix just until the ingredients are combined and a shaggy dough forms. Overmixing will develop the gluten in the flour and result in a tough, chewy crust instead of a tender, crumbly one.
• Prep the Pan: Line your baking pan with parchment paper, leaving a slight overhang on the sides. This makes it incredibly easy to lift the finished bars out of the pan for clean slicing.
• Adjust the Sugar for the Fruit: The sweetness of your fruit will depend on how ripe it is. If your peaches are very sweet, you can use less sugar. If they are a little under-ripe, you may want to add a tablespoon or two more. Taste the fruit mixture before you bake it to get the flavor just right.

✅ Ingredients You’ll Need

Gather your ingredients for this easy and delicious dessert.

• 1½ cups all-purpose flour
• 1 cup old-fashioned rolled oats
• 1 cup light brown sugar, packed
• ½ teaspoon baking soda
• ½ teaspoon salt
• 1 cup (2 sticks) cold unsalted butter, cubed
• 2 large ripe peaches, peeled and diced
• 1 cup fresh or frozen blueberries
• 1 tablespoon granulated sugar
• 1 tablespoon cornstarch
• 1 teaspoon vanilla extract
• ½ teaspoon cinnamon

📋 Step-by-Step Instructions

Follow these simple steps for a perfect batch of blueberry peach crisp bars.

1. Prep the Crumble Dough: In a large bowl, whisk together the flour, oats, brown sugar, baking soda, and salt. Add the cold, cubed butter. Using a pastry blender or your fingertips, cut the butter into the dry ingredients until the mixture resembles coarse crumbs. The mixture should have a sandy texture with some pea-sized pieces of butter remaining.
2. Form the Crust: Press about two-thirds of the crumble mixture evenly into the bottom of a 9×13-inch baking pan to form a firm crust.
3. Prepare the Fruit Filling: In a separate medium bowl, combine the diced peaches, blueberries, granulated sugar, cornstarch, vanilla extract, and cinnamon. Stir until the fruit is evenly coated.
4. Assemble the Bars: Pour the fruit mixture evenly over the shortbread crust. Crumble the remaining one-third of the crumble mixture over the top of the fruit.
5. Bake to Perfection: Bake for 40-50 minutes, or until the filling is bubbling and the topping is golden brown.
6. Cool and Slice: Let the bars cool completely in the pan on a wire rack. This is a crucial step! If you try to slice them while they are warm, they will fall apart. Once they are completely cool, you can lift the whole block of bars out of the pan using the parchment paper overhangs. Slice into squares or rectangles and serve.

Total Preparation and Cooking Time: Approximately 1 hour and 30 minutes. This includes 20 minutes of prep and 1 hour of baking and cooling. The cooling time is crucial for the bars to set.

❓ Frequently Asked Questions

• Can I use frozen fruit? Yes, you can! Frozen fruit works great in this recipe. You don’t need to thaw it first; just add it directly to the bowl with the other fruit ingredients. The baking time may be a few minutes longer.
• What if I don’t have peaches? You can swap the peaches for other stone fruits like nectarines or plums.
• How do I store these bars? You can store the cooled bars in an airtight container at room temperature for up to 3 days. For longer storage, you can freeze them in a freezer-safe container for up to 3 months.
• Why did my bars turn out soggy? This can happen if the fruit was too watery or if you didn’t use enough cornstarch. Using a little more cornstarch can help absorb any excess liquid. Also, make sure to let the bars cool completely before slicing, as this allows the fruit filling to set.

🍽️ Serving & Pairing Suggestions

These blueberry peach crisp bars are perfect on their own, but they’re even better with the right accompaniments.

• A Scoop of Ice Cream: Serve a warm bar with a scoop of vanilla bean ice cream. The combination of hot and cold, and the melting of the ice cream into the bar, is simply divine.
• A Dollop of Cream: A simple dollop of fresh whipped cream or crème fraîche adds a touch of elegance and balances the sweetness of the fruit.
• Coffee or Tea: These bars are a perfect pairing for an afternoon cup of hot coffee or a nice cup of tea. The rich, buttery flavor goes wonderfully with a hot beverage.
