Blueberry Cream Cheese Bars: A Comforting Classic with a Buttery Oat Crust

Sharing is caring!

Some desserts linger in your memory not just for their taste, but for the comforting ritual they bring. Blueberry Cream Cheese Bars are one of those recipes. With their chewy, golden oat crust, rich cream cheese filling, and bursts of juicy blueberry throughout, these bars offer both texture and flavor in each bite. Whether you’re preparing a dessert for a family gathering or simply looking to elevate your weekday snack game, this recipe delivers a wholesome and satisfying treat that feels indulgent but comes together with everyday ingredients.

While these bars may look like something you’d find in a bakery display case, they are surprisingly straightforward to make. In fact, they’re perfect for beginner bakers who want to master a dessert that feels impressive but doesn’t require advanced skills. This version also makes room for flexibility: fresh or frozen blueberries work equally well, and you can even experiment with different fruits or crust variations.

Ingredients and Preparation

Here’s what you’ll need to prepare these Blueberry Cream Cheese Bars, along with a few notes for best results:

For the Crust and Topping:

• ¾ cup unsalted butter, softened
• ⅔ cup granulated sugar
• ⅔ cup brown sugar, packed
• ½ teaspoon baking soda
• ½ teaspoon salt
• 1⅓ cups all-purpose flour
• 1⅓ cups quick-cooking oats (uncooked)

For the Filling:

• 8 ounces cream cheese
• 1 can (14 ounces) sweetened condensed milk
• 1 teaspoon pure vanilla extract
• 1 egg yolk
• 1 cup blueberries (fresh or frozen)

Preparation Tip:
Make sure the butter is soft but not melted, and that the cream cheese is at room temperature to avoid lumps in your filling. If using frozen blueberries, do not thaw them before baking—they’ll release excess liquid if you do.

Step-by-Step Instructions

Step 1: Prep Your Equipment

Start by preheating your oven to 350°F (177°C). Prepare a 9×13 inch baking dish by lining it with parchment paper or greasing it well with non-stick spray. This step ensures the bars will lift out easily once cooled.

Step 2: Make the Crust and Crumble

In a large mixing bowl, cream the softened butter with both the granulated and brown sugars until the mixture is light and fluffy. Add baking soda and salt, mixing just until incorporated. Gradually stir in the flour and oats, blending until a crumbly, cohesive dough forms.

Take half of this mixture and press it firmly into the bottom of your prepared pan. This will be your base. Bake it in the preheated oven for about 13 minutes, or until lightly golden and set.

Step 3: Prepare the Cream Cheese Layer

While the base is baking, start on the filling. In a separate bowl, beat the cream cheese until smooth and lump-free. Gradually whisk in the sweetened condensed milk until fully incorporated and velvety in texture. Add the vanilla extract and egg yolk, mixing until everything is blended and glossy.

Step 4: Assemble the Layers

Once the crust is partially baked, remove it from the oven. Pour the cream cheese mixture over the warm crust and spread it evenly with a spatula. Evenly scatter the blueberries across the cream cheese layer, allowing their natural juices to bake right into the filling.

Sprinkle the remaining oat crumble over the top of the blueberries. Gently press down to slightly adhere the topping to the creamy layer without flattening it.

Step 5: Final Bake

Return the pan to the oven and bake for another 20 to 25 minutes. You’ll know it’s ready when the top is golden brown and slightly firm to the touch. The aroma filling your kitchen is reason enough to make this recipe again.

Step 6: Cooling and Slicing

Let the bars cool completely in the pan, ideally on a wire rack. This step is essential to prevent crumbling when you slice them. Once cool, lift them out using the parchment paper and transfer to a cutting board. Cut into neat squares or rectangles, depending on your preference.

Beginner Tips and Notes

• Avoid Overmixing the Crust: The crust should stay crumbly. Overworking the flour and oats can make it too dense. Mix just until combined.
• Smooth Filling Is Key: Make sure your cream cheese is at room temperature. Cold cream cheese doesn’t incorporate well with the sweetened condensed milk and can lead to lumps.
• Blueberry Placement: Try to distribute the blueberries evenly so each bar has a good balance of fruit.
• Test for Doneness: The edges should be slightly golden and firm, but the center may still have a slight wobble. It will set completely as it cools.
• Easy Cleanup: Lining your pan with parchment makes lifting and cleanup much simpler.

Storage Advice:
To keep these bars fresh, store them in an airtight container in the refrigerator for up to 5 days. If stacking, place parchment paper between layers to prevent sticking. For longer storage, wrap individual bars tightly in plastic wrap and place in a freezer-safe bag. They’ll keep for up to 3 months. Thaw overnight in the fridge before serving.

Creative Variations:

• Other Fruits: Swap blueberries for raspberries, blackberries, or a berry medley. Stone fruits like chopped peaches also work well.
• Crust Alternatives: For a nuttier flavor, try adding a handful of chopped walnuts or almonds to the oat crumble.
• Lemon Zest Boost: Add 1 teaspoon of fresh lemon zest to the filling for a citrusy brightness that pairs beautifully with the blueberries.
• Reduced Sugar Option: Reduce the granulated sugar by 2 tablespoons and increase brown sugar for a deeper, caramel-like flavor.

Reader Q&A:

• Can I make this gluten-free?
  Yes. Substitute the all-purpose flour with a 1:1 gluten-free baking blend and ensure your oats are certified gluten-free.
• Can I use low-fat cream cheese?
  You can, though the texture will be slightly less rich. Avoid fat-free versions—they don’t hold up as well when baked.
• Do these travel well?
  Absolutely. They hold their shape nicely once cooled, making them perfect for picnics or packed lunches.
