Ingredients for Peach Crumble Bars
To make these delicious peach crumble bars, you’ll need the following ingredients:
For the crust and topping:
- 1 cup all-purpose flour (140g)
- 1⅓ cup rolled oats (130g)
- ¾ cup granulated sugar (155g)
- 1 tsp ground cinnamon
- ¼ tsp salt (optional)
- ⅔ cup unsalted butter, melted (150g)
For the peach filling:
1 tsp almond extract (optional)
2 cups peeled, chopped peaches (450g)
2 tbsp sugar (30g)
2 tsp cornstarch
1 tsp fresh lemon juice
How to Make Peach Crumble Bars
Follow these simple steps to make your peach crumble bars:
- Preheat the Oven
Set your oven to 350°F (177°C). Line an 8-inch square baking pan with parchment paper for easy removal. - Prepare the Peaches
Peel (optional) and chop the peaches into ½ to 1-inch pieces. Toss the chopped peaches in a bowl with lemon juice and almond extract. Stir in sugar and cornstarch, then set aside to let the mixture rest. - Make the Dough
In a large bowl, combine flour, oats, sugar, cinnamon, and salt. Add the melted butter and stir until the mixture forms a crumbly dough. - Form the Crust
Press about two-thirds of the dough into the bottom of the prepared pan. This will form the base for your bars. - Add the Peach Filling
Spoon the prepared peach mixture evenly over the crust, being careful to leave any excess juice behind. - Add the Topping
Crumble the remaining dough over the top of the peach filling, pressing it down lightly to help it stick. - Bake the Bars
Bake in the preheated oven for 33–35 minutes, or until the bars are golden and the peach filling is bubbling around the edges. - Cool and Chill
Let the bars cool at room temperature for 1 hour, then place them in the fridge for at least 90 minutes before slicing. This will help them firm up for clean cuts. - Optional Syrup Drizzle
If you reserved some peach juice, you can cook it down into a syrup and drizzle it over the cooled bars for extra flavor.

Pro Tips
- Use Firm Peaches – For the best texture, use ripe but firm peaches. Overripe peaches may release too much juice, making the bars soggy.
- Chill the Bars Before Slicing – For clean and neat slices, make sure the bars are fully chilled in the fridge before cutting. This will help them hold their shape.
- Customize the Flavor – Feel free to swap almond extract with vanilla extract for a different flavor profile, or add a pinch of nutmeg for a warm, spiced touch.
Serving Ideas or Usage Tips
Peach crumble bars are versatile and can be served in many ways:
- Serve Warm with Ice Cream – For a decadent treat, warm up the bars and top them with a scoop of vanilla ice cream.
- Perfect for Breakfast or Snacks – These bars make for a tasty, portable breakfast or afternoon snack with a cup of coffee or tea.
- Great for Picnics or Parties – Their sturdy texture makes these bars perfect for picnics, potlucks, or outdoor gatherings.
No matter how you serve them, peach crumble bars are sure to be a hit!
