Ingredients You’ll Need

The ingredients for these Blueberry Cream Cheese Bars are delightfully simple, yet each one brings an important element to the 4. From a creamy, tangy layer to a crisp oat crumble and gems of fresh blueberries, the combination guarantees both ease and flavor in every bite.

Butter (3/4 cup, softened): Gives the oat crumble its signature richness and golden color, while ensuring the layers stay deliciously tender.
Sugar (2/3 cup): Regular white sugar adds sweetness and helps crisp the crust just right.
Brown sugar (2/3 cup): Brings moisture and a subtle molasses note to balance the tartness of the berries.
Baking soda (1/2 teaspoon): Ensures that the bar layers stay tender without being dense.
Salt (1/2 teaspoon): Accentuates all the flavors and keeps the bars from being overly sweet.
Flour (1 1/3 cups): Gives the bars structure and a sturdy base for slicing.
Quick oats (1 1/3 cups, uncooked): For that fantastic, chewy crumb and a rustic, hearty texture and taste.
Cream cheese (8 ounces): The star of the creamy filling—always use full-fat for maximum richness.
Sweetened condensed milk (1 14-ounce can): Makes the filling extra smooth and provides just the right sweetness.
Vanilla (1 teaspoon): Infuses the cream layer with warm, aromatic undertones.
Egg yolk (1): Improves texture and helps set the creamy filling while baking.
Blueberries (1 cup): Adds juicy bursts of tangy flavor—fresh or frozen both work beautifully, or try raspberries for a twist!

How to Make 4

Step 1: Prepare Your Pan and Ingredients

Start by preheating your oven to 350°F. This is crucial for even baking. Grab a 9×13 pan and either line it with parchment paper or give it a generous coat of cooking spray. This makes removing the 4 a total breeze later!

Step 2: Mix Up the Oat Crumble

In a large bowl, combine the softened butter with the sugar and brown sugar, mixing until everything is pale and fluffy. Next, stir in the baking soda, salt, flour, and quick oats. The mixture should look like crumbly, sandy dough ready to be both the top and bottom layer of your fabulous 4.

Step 3: Bake the Base Layer

Take half of your oat crumble and press it firmly into the bottom of your prepared pan, making an even layer. Pop it into the oven and bake for 13 minutes. This step gives you a sturdy, golden base that can hold the luxurious cream cheese filling without getting soggy.

Step 4: Whip Up the Creamy Filling

While your base is baking, beat the cream cheese in a large bowl until it’s supremely smooth and creamy. Gradually whisk in the sweetened condensed milk, ensuring no lumps remain. Add the vanilla and egg yolk, and keep whisking until it’s all silky and blended. This is the creamy heart of your 4!

Step 5: Assemble the Bars

Take the par-baked base out of the oven and carefully pour the cream cheese mixture over the top, spreading it all the way to every edge. Evenly scatter the blueberries (or raspberries) over the filling for perfect fruity flavor in every bite. Crumble the remaining oat mixture over the top and press it down lightly—this is what gives these 4 their signature crunch and look!

Step 6: Bake to Golden Perfection

Return the pan to the oven and bake for 20 to 25 minutes. You’re looking for those edges to turn beautifully golden and the center to just set. Resist the urge to slice right away—let these bars cool completely for the cleanest cuts and creamiest texture.

How to Serve 4

Garnishes

For an extra pop of color and a flavor lift, add a handful of fresh blueberries on top right before serving. A dusting of powdered sugar makes your 4 look bakery-worthy, while a dollop of whipped cream or a drizzle of lemon glaze adds a fun finishing touch that guests will rave about.

Side Dishes

Bring even more comfort to your dessert table by pairing the 4 with a hot cup of tea, strong coffee, or a cool glass of milk. For parties or potlucks, serve alongside a vibrant fruit salad or a scoop of vanilla ice cream for a little creamy contrast—everyone will be reaching for seconds!

Creative Ways to Present

These bars aren’t just tasty—they’re pretty versatile, too! Try cutting your 4 into bite-sized squares for a dessert platter, or stack them in parchment for a rustic picnic feel. If you’re feeling fancy, top with edible flowers or lemon zest for bright color and aroma. They also make a charming edible gift packaged in a pretty box.

Make Ahead and Storage

Storing Leftovers

The 4 keeps beautifully in the fridge for up to four days. Tuck leftover squares into an airtight container, separating layers with parchment paper if you’re stacking, to keep the oat crumble from getting too soft.

Freezing

If you want to prep 4 ahead of time, tightly wrap the cooled, unsliced bars in plastic wrap and then foil, and freeze for up to three months. Thaw overnight in the fridge before slicing and serving for best texture and flavor.

Reheating

While these bars taste divine cold, if you prefer a just-baked vibe, pop a bar in the microwave for 10-15 seconds. This makes the cream cheese filling extra gooey, and even wakes up the aroma of the oat crumble—absolutely irresistible.

FAQs

Can I use frozen blueberries for these bars?

Yes, you can use frozen blueberries without thawing—just toss them right on top of the cream cheese layer. This makes the 4 super convenient any time of year, and you won’t have to worry about extra moisture!

Is it possible to substitute raspberries or another fruit?

Absolutely! Swap the blueberries for an equal amount of raspberries, blackberries, or even a mixed berry medley for a twist on the classic 4. Just be aware that juicier fruits may change the final texture slightly.

How do I know when the bars are done baking?

The edges of the 4 should be golden brown and the middle should look set—not jiggly. If in doubt, a toothpick inserted near the center should come out mostly clean, with just a touch of creamy filling clinging to it.

Can I make the oat crumble gluten-free?

Yes! Substitute the flour for a 1:1 gluten-free baking blend and make sure to use certified gluten-free oats. The result is just as delicious, and no one will miss the gluten in these fabulous 4.

Why do I need to cool the bars before cutting?

The cooling time helps the cream cheese layer firm up, so your 4 slice beautifully and hold their shape rather than collapsing into a gooey mess. Patience pays off for picture-perfect dessert squares!
