Raspberry Lemon Squares (Diabetes-Friendly)

I remember the first time I tasted lemon squares. It was at my grandmother’s house, a bright, sun-drenched kitchen filled with the aroma of citrus and freshly baked goods. The squares were perfectly tart and sweet, a delightful combination that danced on my tongue. I’ve been chasing that perfect lemon square ever since, and I’m thrilled to share this diabetes-friendly version that captures the essence of that memory without all the sugar. The addition of raspberry jam adds a delightful twist that complements the lemon beautifully, creating a treat that’s both satisfying and guilt-free.

Recipe Overview

Cook Time: 34 minutes
Total Time: 61 minutes
Servings: 16
Yield: 16 squares
Dietary Type: Diabetes-Friendly

Ingredients

For the Crust:
- 3/4 cup all-purpose flour
- 3 tablespoons sugar
- 1/8 teaspoon ground nutmeg
- 1/4 cup butter
For the Filling:
- 2/3 cup sugar
- 1/3 cup egg substitute
- 3 tablespoons lemon juice
- 2 teaspoons lemon peel
- 1/4 teaspoon baking powder
- 3 tablespoons seedless raspberry jam
For Garnish:
- 1 tablespoon powdered sugar

Equipment Needed

8-inch square baking pan
Small bowl
Pastry blender or 2 knives
Whisk
Microwave-safe bowl
Wire rack

Instructions

Preheat your oven to 350°F (175°C). Make sure the rack is in the center position for even baking.
To prepare the crust, lightly spoon the flour into dry measuring cups and level with a knife. This ensures you are not using too much flour which can result in a dry crust.
In a small bowl, combine the measured flour, 3 tablespoons of sugar, and ground nutmeg. Whisk together to ensure the nutmeg is evenly distributed.
Using a pastry blender or two knives, cut the butter into the flour mixture until it resembles coarse meal. The butter should be cold for this step. This will help create a flaky crust.
Press the mixture firmly into the bottom of an 8-inch square baking pan. Use your fingers or the back of a spoon to create an even layer.
Bake the crust at 350°F (175°C) for 12 minutes, or until it is lightly golden brown. This partially bakes the crust so it can support the filling without becoming soggy.
While the crust is baking, prepare the lemon filling. In a separate bowl, combine 2/3 cup of sugar, egg substitute, lemon juice, lemon peel, and baking powder.
Whisk the ingredients together until well blended. Ensure there are no lumps from the baking powder.
Remove the crust from the oven and immediately pour the lemon mixture over the warm crust. Spread the lemon filling evenly over the crust.
In a small microwave-safe bowl, place the seedless raspberry jam. Microwave on HIGH for 30 seconds, or until melted. Be careful as the jam can get very hot.
Drizzle the melted raspberry jam over the lemon mixture in a decorative pattern. You can use a spoon or a piping bag for more precise application. Swirl with a knife or toothpick if desired for a marbled effect.
Return the baking pan to the oven and bake at 350°F (175°C) for 22 minutes, or until the edges are very lightly browned and the filling is set. The center should still have a slight jiggle.
Remove from the oven and cool completely on a wire rack. Cooling the squares completely is important for setting the filling and making them easier to cut.
Once completely cool, sift powdered sugar evenly over the top. This adds a touch of sweetness and visual appeal.
Cut into 16 squares and serve. Use a sharp knife for clean cuts.

Expert Tips & Tricks

For an extra burst of lemon flavor, add a pinch of lemon zest to the crust.
If you don’t have a pastry blender, you can use a food processor to combine the butter and flour for the crust. Pulse until the mixture resembles coarse crumbs.
To prevent the crust from sticking to the pan, you can line the baking pan with parchment paper, leaving an overhang to easily lift the baked squares out.
If the edges of the squares are browning too quickly, you can cover the baking pan loosely with foil during the last 10 minutes of baking.
For easier cutting, chill the squares in the refrigerator for at least 30 minutes before slicing.
If you find the lemon flavor too tart, you can add a touch of your favorite sweetener.

Serving & Storage Suggestions

FAQs (Frequently Asked Questions)

Q: Can I use fresh raspberries instead of jam?
A: While you can use fresh raspberries, the jam provides a more concentrated raspberry flavor and helps bind the filling together. If you use fresh raspberries, be sure to mash them slightly and drain off any excess liquid before adding them to the filling.

Q: How do I prevent the crust from getting soggy?
A: Par-baking the crust before adding the filling is key to preventing a soggy crust. Also, be sure to cool the squares completely before cutting to allow the filling to set properly.

Q: Can I make these squares ahead of time?
A: Yes, these squares can be made a day or two in advance. Store them in an airtight container in the refrigerator until ready to serve.

Q: My filling is still jiggly after the baking time. What should I do?
A: If the filling is still too jiggly, continue baking for another 5-10 minutes, checking frequently to ensure the edges don’t burn. Ovens can vary, so baking times may need to be adjusted.

Q: Can I freeze these raspberry lemon squares?
A: Yes, these squares freeze well. Cut them into individual squares, place them on a baking sheet lined with parchment paper, and freeze until solid. Then, transfer them to a freezer-safe container for long-term storage. Thaw in the refrigerator before serving.
