Peach Crumble Bars
Ingredients
- 1 cup unsalted butter browned
- 1 cup brown sugar
- 2 cups all-purpose flour
- 1 cup rolled oats
- 1 tsp baking powder
- 0.5 tsp salt
- 1 large egg
- 1 tsp vanilla extract alcohol-free
- 3 cups fresh peaches peeled and diced
- 1 tbsp lemon juice
- 2 tbsp cornstarch
- 1 tsp cinnamon
- 2 tbsp sugar for the peach filling
Instructions
- Cook the butter in a saucepan over medium heat until it turns golden and smells nutty. Let it cool slightly before using, so it blends smoothly into the dough.
- Stir the brown butter with the sugar, egg, and alcohol-free vanilla. Mix in the flour, oats, baking powder, and salt until a crumbly dough forms.
- In a bowl, toss the diced peaches with sugar, lemon juice, cornstarch, and cinnamon. Let the mixture sit for a few minutes so the juices start to come together.
- Press most of the crumble mixture into a lined baking pan. Spread the peach filling evenly over the base, then sprinkle the remaining crumble on top.
- Bake until the top is golden brown and the filling is bubbling at the edges. Let the bars cool completely before slicing, so they hold together nicely.

Peach Crumble Bars Ingredients & Substitutions
- Unsalted butter, browned for a rich, nutty flavor
- Brown sugar, for sweetness and moisture
- All-purpose flour, for the crust and crumble
- Rolled oats, for extra texture in the topping
- Baking powder, to help the crust stay tender
- Salt, to balance the sweetness
- Egg, to bind the crust
- Alcohol-free vanilla, for warm flavor
- Fresh peaches, peeled and diced
- Lemon juice, to brighten the filling

If fresh peaches are not in season, you can use frozen peaches, just thaw and drain them well first. A spoonful of peach jam can also boost flavor if your fruit is a little mild. For a slightly different texture, you can swap part of the oats for chopped nuts.
Step-by-Step Instructions to Make Peach Crumble Bars
Step 1: Brown the butter
Cook the butter in a saucepan over medium heat until it turns golden and smells nutty. Let it cool slightly before using, so it blends smoothly into the dough.
Step 2: Make the crust and crumble
Stir the brown butter with the sugar, egg, and alcohol-free vanilla. Mix in the flour, oats, baking powder, and salt until a crumbly dough forms.
Step 3: Prepare the peach filling
In a bowl, toss the diced peaches with sugar, lemon juice, cornstarch, and cinnamon. Let the mixture sit for a few minutes so the juices start to come together.
Step 4: Assemble the bars
Press most of the crumble mixture into a lined baking pan. Spread the peach filling evenly over the base, then sprinkle the remaining crumble on top.
Step 5: Bake until golden
Bake until the top is golden brown and the filling is bubbling at the edges. Let the bars cool completely before slicing, so they hold together nicely.
Tips for Success
Cool the brown butter just enough so it does not cook the egg when mixed in. Use ripe peaches for the best flavor, and do not skip the cooling time after baking, because the filling sets as the bars rest. For cleaner cuts, chill the bars briefly before slicing.
Variations of Peach Crumble Bars
You can add a handful of blueberries or raspberries to the peach filling for a mixed fruit version. If you like warm spice, a little nutmeg or cardamom works beautifully. For extra crunch, add chopped almonds or pecans to the topping.
Serving Suggestions: What to Pair with Peach Crumble Bars
These bars are lovely with a scoop of vanilla ice cream or a dollop of whipped cream. They also go well with coffee, iced tea, or a cold glass of milk. For brunch, serve them alongside fresh fruit and yogurt.
Storage & Reheating Instructions
Store the bars in an airtight container at room temperature for up to 2 days, or refrigerate them for up to 5 days. If you want them warm, heat individual bars in the microwave for a few seconds. They also freeze well, wrapped tightly and stored in a freezer-safe container.

FAQs
Can I use canned peaches?
Yes, canned peaches work well if you drain them thoroughly first. Pat them dry before mixing with the filling ingredients so the bars do not turn watery.
Can I make these bars ahead of time?
Absolutely. These bars are a great make-ahead dessert because they slice best after cooling completely. You can bake them a day in advance and store them covered.
Why did my crumble topping sink?
If the base was too soft or the filling was too wet, the topping can sink a bit. Make sure the crust is firmly pressed into the pan and that the peaches are well drained.
Can I double the recipe?
Yes, you can double the recipe and bake it in a larger pan. Just keep an eye on the bake time, since a bigger batch may need a few extra minutes.
