The dessert has a smooth texture with vibrant marbling patterns on top and through the middle layers, giving a glossy and rich look. Around the squares, there are fresh blueberries scattered on the plate, adding a contrasting deep blue color.

Ingredients

½ cup frozen blueberries
2 tablespoons granulated sugar

1 tablespoon freshly squeezed lemon juice
1½ teaspoons cornstarch

3 cups white baking chips (I used Nestle)
1 cup sweetened condensed milk

Instructions

Step 1: Line an 8×8 baking dish with parchment paper, leaving an overhang on two sides to lift the fudge out later. Lightly spray the parchment with nonstick cooking spray and set aside.
Step 2: In a 1 to 2-quart heavy-bottomed saucepan over medium-low heat, combine frozen blueberries, sugar, lemon juice, and cornstarch. Stir constantly, breaking up the berries, until the mixture thickens to a very thick pie filling consistency, about 8-10 minutes.
Step 3: Place a fine-mesh strainer over a medium bowl. Pour the blueberry mixture into the strainer and use a spatula to press the topping through. Discard the berry hulls. Cover and chill this blueberry topping in the refrigerator for 1 hour.

Step 4: In a microwave-safe bowl, heat the white baking chips on high for 1 minute. Stir well, then continue heating in 30-second intervals, stirring after each, until melted and smooth. Avoid overheating to prevent graininess.
Step 5: Warm the sweetened condensed milk in a small microwave-safe bowl for 45 seconds to 1 minute until warm but not boiling.
Step 6: Stir the warm sweetened condensed milk into the melted white chocolate. The mixture may seem grainy at first but will become smooth with stirring.

Step 7: Gently fold the chilled blueberry topping into the white chocolate mixture no more than three times to create a marbled effect. Immediately pour the mixture into the prepared baking dish. Cover and refrigerate for 3-4 hours until set.
Step 8: Once set, lift the fudge out of the dish using the parchment overhang. Slice into 6 by 6 pieces and keep refrigerated until serving.

Tips & Variations

For a deeper blueberry flavor, use fresh blueberries in season or add a teaspoon of blueberry jam to the topping before thickening.

Swap white baking chips with white chocolate bars for a richer texture, just melt gently using a double boiler.
If you prefer a smoother fudge, strain the blueberry topping twice to remove more seeds and hulls.

Storage

Store the fudge in an airtight container in the refrigerator for up to one week. Before serving, you can let the fudge sit at room temperature for a few minutes for a softer bite. Avoid freezing, as this can affect the texture.

How to Serve

This image shows several small square pieces of creamy white fudge with deep purple swirls spread inside, giving a marbled look. The fudge is stacked in layers, some pieces resting on top of others, with clear smooth edges. The purple swirls twist through each piece in thin veins, adding color contrast. Fresh blueberries are placed near the fudge on a white marbled surface, with a white bowl filled with more food blurred in the background. One piece of fudge has a bite taken out, showing the soft texture inside. The overall look is soft and rich with a mix of creamy white and dark purple shades. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use fresh blueberries instead of frozen?

Yes, fresh blueberries can be used. Just rinse and dry them before cooking. The texture and flavor will be just as good, especially when berries are in season.

Why is the fudge grainy sometimes?

Overheating the white chocolate or not stirring well when mixing in the sweetened condensed milk can cause graininess. Melt the chocolate gently and combine ingredients carefully to keep the texture smooth.
