- Gluten-Free Option: To make this recipe gluten-free, substitute the all-purpose flour with a gluten-free flour blend. Ensure the blend contains xanthan gum or add ½ teaspoon yourself to help with texture.

Step-by-Step Cooking Instructions

Creating these delicious crumb bars is a straightforward process. Follow these simple steps, and you’ll have a perfect batch of Lemon Strawberry Crumb Bars in no time.
Step 1: Prepare the Crust and Topping
- Preheat the oven to 350°F (175°C). Line a 9x13-inch baking pan with parchment paper, leaving some overhang for easy removal of the bars later.
- In a large mixing bowl, combine flour, granulated sugar, brown sugar, and salt.
- Add the cold butter cubes to the dry ingredients. Using a pastry cutter or your hands, mix the butter into the flour mixture until it resembles coarse crumbs. The butter should still be visible in small chunks.
- Stir in the lemon zest and vanilla extract to add extra flavor.
- Take about ⅔ of the mixture and press it firmly into the bottom of your prepared baking dish. This will form the base of your crumb bars.
- Set aside the remaining ⅓ of the crumble mixture to be used as the topping.
Step 2: Prepare the Strawberry Lemon Filling
- In a medium saucepan, combine the chopped strawberries, sugar, cornstarch, lemon juice, lemon zest, and vanilla extract.
- Heat the mixture over medium heat, stirring occasionally. As the strawberries soften and release their juices, continue cooking until the mixture thickens, about 5-7 minutes. The cornstarch will help the filling set properly.
- Remove the strawberry mixture from heat and let it cool for a few minutes.
Step 3: Assemble and Bake
- Pour the cooled strawberry lemon filling over the pressed crust in the baking pan, spreading it out evenly with a spatula.
- Sprinkle the remaining crumb mixture evenly over the top of the filling. You want to ensure that you cover most of the filling, but it's okay if some strawberry mixture peeks through.
- Place the pan in the oven and bake for 35-40 minutes, or until the top crumble turns golden brown and the filling is bubbly.
- Once baked, remove the bars from the oven and allow them to cool in the pan for at least 30 minutes before cutting.
Step 4: Chill and Serve
For the best texture and flavor, it's a good idea to refrigerate the bars for about an hour before serving. This helps the filling set completely, making it easier to slice the bars cleanly.
How to Cook Lemon Strawberry Crumb Bars: A Step-by-Step Guide
Making the perfect Lemon Strawberry Crumb Bars requires a few essential steps that ensure each bite is packed with flavor and texture. Here's a quick step-by-step guide:
- Prepare your crust and crumble by mixing butter, flour, and sugar until you have a coarse crumb.
- Cook the strawberry lemon filling to create a thick, jam-like texture.
- Assemble the layers by pressing the crumble mixture into the pan, adding the strawberry filling, and topping with the remaining crumble.
- Bake until golden and let the bars cool before serving.
Common Mistakes to Avoid
While this recipe is fairly simple, a few common mistakes can affect the outcome. Here are a few to watch out for:
- Using soft butter: Cold butter is essential for creating a crumbly texture. If your butter is too soft, the mixture will become too sticky.
- Overcooking the filling: Cook the strawberry lemon filling just until it thickens. Overcooking can result in a too-thick consistency, which may not spread well on the base.
- Not pressing the crust firmly enough: Make sure to press the bottom layer firmly into the pan. If it’s too loose, the bars might fall apart after baking.
- Not letting the bars cool: Cutting into the bars too soon can cause them to fall apart. Be patient and let them cool completely before slicing.
