How to Prepare Sweet Blackberry Crumble Bars

Alright, let’s get these sweet blackberry crumble bars in the oven! It’s easier than you think, I promise. Just follow these steps and you’ll be enjoying them soon.

Preparing the Pan for Sweet Blackberry Crumble Bars

First things first, get your oven ready! Preheat it to 375°F (190°C). Then grab your 9×13 inch baking pan. Give it a good greasing and dusting with flour. This helps the bars release easily later.

Creating the Crumble Mixture

Now for the heart of our sweet blackberry crumble bars! In a big bowl, whisk together the flour, oats, brown sugar, baking powder, and salt. Add your cold butter pieces. Cut the butter into the dry stuff using a pastry blender or your fingers. You want it to look like coarse crumbs.

Assembling Your Sweet Blackberry Crumble Bars

Take half of that lovely crumb mixture. Press it down firmly and evenly into the bottom of your prepared pan. This is your crust! In another bowl, gently toss the blackberries with the granulated sugar, cornstarch, and lemon juice. Pour this juicy berry mix right over the crust.

Baking Your Sweet Blackberry Crumble Bars to Perfection

Now, sprinkle the rest of the crumb mixture over the top of the blackberries. Pop the pan into your preheated oven. Bake for about 45 to 55 minutes. You’ll know they’re ready when the topping is golden and the berry filling is bubbly around the edges.

Cooling Your Sweet Blackberry Crumble Bars

Okay, this is the hardest part: patience! Once they’re out of the oven, you absolutely MUST let the sweet blackberry crumble bars cool completely in the pan. I know it’s tempting, but this is key for them to hold their shape when you cut them. Trust me on this!
