Lemon Raspberry Bars Ingredients & Substitutions

These simple ingredients come together to create layers of flavor and texture in every bite.

• Granulated Sugar: Sweetens both the crust and the filling while helping create structure. Organic cane sugar can be used.
• Lemon Zest: Adds bold citrus flavor directly into the shortbread base.
• Salted Butter: Creates a rich, tender crust. Use plant-based butter for a vegan option.
• Vanilla Extract: Enhances the sweetness and rounds out the flavors.
• Flour: Forms the base of the shortbread. Use all-purpose or a 1:1 gluten-free blend.
• Fine Sea Salt: Balances sweetness and enhances flavor.
• Raspberries: The star of the filling: tart, juicy, and naturally sweet. Fresh or frozen, both work. If using frozen, thaw first and drain excess juice.
• Lemon Juice: Brightens the filling and ties everything together. Fresh is always best, but bottled will work.
• Cornstarch: Thickens the raspberry layer so it sets beautifully. Tapiocha starch can be used as well.
• Powdered Sugar: Creates a smooth, sweet glaze.
• Extra Lemon Juice (for glaze): Adds a tangy finish and balances the sweetness.

Lemon Raspberry Shortbread Bars Step-by-Step Instructions

These bars come together in a few simple steps, with layering doing most of the magic. So preheat the oven, grab a spatula, and let’s get baking!

1. Prep: Preheat the oven to 350°F and line an 8×8-inch pan with parchment paper in a crisscross pattern.
2. Infuse sugar: Beat the sugar and lemon zest together on high speed for 1 minute to release the oils.
3. Cream butter: Add the butter and vanilla and beat until light and fluffy, about 2–3 minutes.
4. Form dough: Mix in the flour and salt on low speed until a crumbly dough forms.
5. Build the base: Press ⅔ of the dough evenly into the prepared pan.
6. Make filling: Toss raspberries with sugar, lemon juice, and cornstarch until combined.
7. Layer filling: Spoon the raspberry mixture over the crust, leaving excess liquid behind.
8. Add crumble topping: Crumble the remaining dough evenly over the raspberries.
9. Bake: Bake for about 60 minutes, until the top is lightly golden.
10. Cool completely: Let the bars cool fully in the pan before glazing.
11. Glaze: Mix powdered sugar and lemon juice until smooth, then drizzle over the bars.
12. Slice & serve: Cut into squares and enjoy!
