4. Step-by-Step Instructions
Step 1: Prep the Pan
- Preheat your oven to 350°F (175°C).
- Line an 8×8-inch baking dish with parchment paper, leaving some overhang for easy removal.
Step 2: Make the Crumble Mixture
- In a large mixing bowl, combine flour, oats, brown sugar, baking powder, salt, and cinnamon.
- Cut in the cold butter using a pastry cutter, fork, or your fingers until the mixture resembles coarse crumbs.
- Stir in vanilla extract.
- Set aside 1 cup of the mixture for the topping.
Step 3: Create the Crust
- Press the remaining crumble mixture into the bottom of the prepared pan.
- Use the back of a spoon or your fingers to press it into an even, compact layer.
Step 4: Prepare the Peach Filling
- In another bowl, mix sliced peaches with sugar, lemon juice, cornstarch, and cinnamon.
- Stir gently to coat the peaches evenly.
Step 5: Assemble the Bars
- Pour the peach filling evenly over the crust.
- Sprinkle the reserved crumble mixture over the top.
Step 6: Bake
- Bake for 40–45 minutes until the topping is golden brown and the peach layer is bubbling.
- Cool completely in the pan before slicing into squares.
5. Expert Baking Tips
- Use ripe peaches for maximum flavor and natural sweetness. Avoid hard or under-ripe fruit.
- Chill the crumble mixture briefly for extra crispiness in the topping.
- Don’t skip the parchment paper—it makes removing and slicing the bars much easier.
- Let the bars cool completely before slicing; warm fruit filling will fall apart if cut too early.
6. Ingredient Substitutions & Variations
✅ Substitutions:
- Butter → use coconut oil or vegan butter for a dairy-free version.
- Brown sugar → substitute coconut sugar for a refined sugar-free option.
- Flour → use a gluten-free blend for a GF variation.
🍓 Variations:
- Mixed fruit: Try combining peaches with berries like raspberries or blueberries.
