Ingredients You’ll Need

This recipe is broken down into three main components: the blueberry topping, the pecan crust, and the creamy filling.

Blueberry Topping

• 2 pints fresh blueberries (approx. 4 cups)
• ¼ cup granulated sugar
• 2 tbsp brown sugar
• 1 tbsp water
• 1½ tbsp cornstarch mixed with 1½ tbsp water
• 1 tsp lemon zest
• ½ tsp lemon juice

Crust

• ¾ cup butter, melted
• 2 cups all-purpose flour
• 1 cup chopped pecans, toasted or un-toasted (toasting enhances the nutty flavor)

Filling

• 2 cups heavy whipping cream
• 2 cups plus 2 tbsp powdered sugar
• 16 oz cream cheese, softened
• 1 tsp vanilla extract

Step-by-Step Instructions

Making this dessert involves three layers that come together beautifully: the crust, the creamy filling, and the fresh blueberry topping.

Step 1: Prepare the Blueberry Glaze

1. In a saucepan, add 1 pint (about 2 cups) of blueberries, granulated sugar, brown sugar, and 1 tablespoon of water.
2. Place the pan over medium heat and stir continuously. As the berries heat up, gently smash a few of them to release juice and prevent the sugar from burning.
3. Once the sugar dissolves and the mixture begins to boil, add the cornstarch-water mixture. Continue stirring until it thickens slightly, about 1 minute.
4. Remove from heat and add the remaining 1 pint of fresh blueberries, lemon zest, and lemon juice. Stir gently until combined.
5. Transfer the mixture to the refrigerator to cool completely. The topping must be cold before layering on the dessert.

Step 2: Make the Pecan Crust

1. Preheat the oven to 325°F (163°C).
2. In a bowl, mix together the melted butter, flour, and chopped pecans until fully incorporated.
3. Grease a 9×13 baking dish with non-stick spray. Press the crust mixture evenly into the bottom.
4. Bake for 15 minutes, then remove from the oven and let it cool. For faster cooling, place the crust in the refrigerator.

Step 3: Whip the Filling

1. In one mixing bowl, whip the heavy cream with the vanilla until thick but not stiff—think soft peaks.
2. In another bowl, blend the softened cream cheese and powdered sugar until smooth and creamy.
3. Combine both mixtures in a larger bowl and beat for 1–2 more minutes, ensuring everything is evenly blended.

Step 4: Assemble the Blueberry Jamboree

1. Spread the creamy filling evenly over the cooled crust.
2. Gently spoon the cooled blueberry topping over the filling, covering the entire surface.
3. Cover the pan with plastic wrap or foil and refrigerate for at least 2 hours (overnight is best for maximum flavor).
4. Slice into squares and serve chilled.

Serving Suggestions

• Chilled is best: This dessert tastes best when served cold.
• Add extra garnish: A dollop of whipped cream or a few fresh mint leaves can elevate the presentation.
• Perfect pairings: Serve alongside coffee or tea for a balanced finish to a meal.

Tips for Success

1. Use fresh blueberries – While frozen blueberries work in a pinch, fresh ones give the best flavor and texture. If using frozen, thaw and drain them first.
2. Cool completely before layering – The blueberry topping must be cooled before adding it to the filling, or it will melt the creamy layer and ruin the structure.
3. Don’t overwhip the cream – Stop whipping when you see soft peaks. Overwhipped cream can separate and affect the texture.
4. Toast the pecans – A quick 5-minute toast in the oven enhances their nutty richness and adds depth to the crust.
5. Chill overnight for best results – While you can serve this dessert after a couple of hours, letting it rest overnight allows the flavors to fully develop.

Why This Recipe Works

• Balanced sweetness: The tang of the blueberries pairs perfectly with the creamy filling and nutty crust.
• Textural contrast: You get crunch from the pecans, smoothness from the cream cheese, and juiciness from the berries.
• Make-ahead friendly: This dessert actually improves as it sits in the fridge, making it ideal for parties or holiday gatherings.

Variations to Try

• Mixed Berry Jamboree: Replace half the blueberries with raspberries or blackberries.
• Gluten-Free Version: Use gluten-free flour for the crust.
• Nut-Free Option: Swap the pecans for crushed graham crackers or leave them out entirely.
• Citrus Twist: Add orange zest instead of lemon for a different flavor profile.

FAQs About Copycat Magnolia Bakery’s Blueberry Jamboree

Can I make this dessert ahead of time?
Yes! In fact, it tastes even better the next day. You can prepare it 24 hours in advance and store it in the fridge.

How long does it last in the refrigerator?
When covered properly, it will last up to 4–5 days in the fridge.

Can I freeze Blueberry Jamboree?
Freezing is not recommended because the creamy filling may separate and the texture won’t be as smooth once thawed.

Do I need to toast the pecans?
It’s optional but highly recommended. Toasting enhances the flavor and adds a pleasant crunch.

Can I use frozen blueberries?
Yes, but thaw and drain them well before cooking. Keep in mind that frozen berries may release more liquid, so you might need a little extra cornstarch to thicken the topping.

What size pan works best?
A standard 9×13-inch baking dish works perfectly. For thicker layers, you can use a smaller dish, but the chilling time may increase.
