🔪 How To Make Peach Crumble Bars

On paper, it may seem like a lot, but these dessert bars are practically fool-proof. They're so easy! You will need your measuring utensils, a mixing bowl, a silicone spatula, and an 8x8 baking dish to get started.

This 8x8 crumble makes about 12 smaller dessert bars, though you can always cut larger pieces if you like!

Prep & Make The Peach Filling

Step 1: Prep. Preheat your oven to 350°F(175°C/Gas Mark 4)and lightly grease an 8x8 baking dish, then line it with some overhanging parchment paper for easy bar removal.

Step 2: Make the filling. In a medium-sized bowl, toss together the2 cups (308 grams) of peaches,1 teaspoon (4.93 milliliters) of lemon juice, and1 teaspoon (4.93 milliliters) of vanilla extract. Once fully coated, add the2 teaspoons (4 grams) of cornstarchand2 tablespoons (24 grams) of sugarand mix well. Set it aside.

Make The Crumble & Assemble

Step 3: Make the Crumble. In a separate medium-sized mixing bowl, combine 1 cup (125 grams) of all-purpose flour,¾ cup (150 grams) of sugar,1⅓ cups (108.1 grams) of old-fashioned rolled oats,1 teaspoon (2 grams) of cinnamon, and optional¼ teaspoon (1.5 grams) of saltand/or¼ teaspoon (0.5 grams) of nutmeg. Drizzle in the melted⅔ cup (151.3 grams) of butterand stir to combine.

Step 4: Assemble your dessert bars. Use a spatula to evenly spread ⅔ of the oat mixture into your baking dish, making sure to cover the entire bottom. Then, spoon the peach mixture over top of the oats (but leaving any extra liquid in the bowl). Crumble and sprinkle the remaining oat mixture over the top, gently pressing it into the peaches using your fingers.

Bake & Serve

Step 5: Bake. Bake in the oven at 350°F (175°C/Gas Mark 4) for 30-35 minutes or until the oat topping is golden brown.

Step 6: Remove the bars from the oven and let them cool completely to room temperature. For neat and clean cuts, chill it in the fridge before slicing.

A scoop of something cool and creamy like whipped cream, chantilly cream, or even vanilla ice cream really elevates these crumble bars to the next level! However, you won't hear any complaints if you serve them just as they are! Enjoy!

💭 Tips & Notes

• 2 cups of chopped peaches equals about 3-4 medium-sized peaches.
• You can easily make this recipe using your preferred variety or combination of fruits! Try using a mixture of both peaches and blueberries or peaches and strawberries! It should work fine as long as it equals about 2 cups of fruit.
• Whether or not you want to leave the peel on the peaches is completely up to you. I don’t feel like it is necessary to take the extra step of peeling, but you can if you like!
• I recommend using fresh peaches, but you can also make this with canned or frozen. If using canned, let them drain thoroughly first. If using frozen, you can use them straight out of the freezer without needing to thaw them first.

🥄 Make Ahead Options

Your peach crumble bars can be made 1-2 days in advance and refrigerated until needed. They're delicious right out of the fridge, or you can set them out at room temperature for 30 minutes to an hour before serving.

Freezing Peach Crumble Bars

You can freeze the bars by either placing a lid on the baking sheet or wrapping them tightly with plastic wrap(or placing the bars into a sealed container). They can be frozen for up to 3 months.

Let them thaw overnight in the fridge before serving.

🥡 Storing

Keep any leftover peach crumble bars stored in a sealed container in the refrigerator for 4-5 days.
