Tasty Blueberry Cheese Bars

These layered blueberry cheesecake squares blend smooth, tangy, fruity and crispy elements perfectly. The crumbly oat foundation doubles as a topping for the velvety cheese layer packed with juicy blueberries. They'll vanish fast at any family dinner or community gathering.

I first baked these squares for a backyard cookout one summer and they were gone in seconds. Now they've turned into my go-to treat that everyone asks me to bring whenever we hang out.

Ingredients

• Butter: Let it sit until soft so it mixes well and makes the crust more delicate
• Granulated sugar and brown sugar: This combo gives just the right sweetness while brown sugar adds richer taste
• Baking soda: Gives the crust a slight lift for better texture
• Salt: Brings out all the tastes, especially making sweet things pop
• All-purpose flour: Forms the base structure in the crust
• Quick oats, uncooked: Gives a satisfying crunch and subtle earthy flavor
• Cream cheese: Regular full-fat works way better for a fuller, creamier middle
• Sweetened condensed milk: Makes everything silky and helps it set up nicely
• Vanilla extract: Adds a gentle warmth that makes the cheese taste better
• Egg yolk: Helps firm up the filling so it cuts cleanly
• Fresh blueberries: Pop with flavor during baking; grab ones that look plump and fresh

Step-by-Step Instructions

Prepare the Oven and Pan:

Set your oven to 350°F. Put parchment in a 9×13 baking dish with extra hanging over the sides for lifting later, or just spray it well with cooking spray. Using parchment makes cleanup super easy and helps get perfect squares.

Make the Crust Mixture:

In a big bowl, beat the soft butter with both sugars until it's fluffy and light, taking about 2 minutes. Mix in the baking soda and salt, then slowly work in the flour and oats until you've got a crumbly mix that sticks together when squeezed. It should look kind of like damp sand with little chunks.

Prebake the Bottom Crust:

Push half the oat mix firmly into your pan, making it flat and even. A measuring cup's bottom works great for pressing it down solid. Bake it for 13 minutes until it's starting to set but not getting brown yet. This quick bake keeps your bottom from turning mushy.

Prepare the Cream Cheese Filling:

While that's baking, put cream cheese in a big bowl and mix until it's totally smooth with zero lumps. Slowly pour in the sweetened condensed milk while mixing constantly to get it super smooth. Add vanilla and egg yolk, stirring until everything's mixed well. The filling should pour but still be on the thick side.

Assemble and Top:

Pour your cheese mix over the warm crust and spread it out evenly with a spatula. Scatter blueberries all over the cheese layer. Sprinkle the rest of your oat mix on top and lightly press it down so it sticks. Try to cover all the filling for the prettiest look.

Bake to Golden Perfection:

Put the pan back in the oven for 20–25 minutes until the edges turn golden and the middle looks mostly firm but wobbles slightly when shaken. It'll keep firming up as it cools, so don't leave it in too long.

Pin it

The sweetened condensed milk really makes these bars stand out from the crowd. I found this key ingredient after trying tons of different cheese bar recipes, and it truly changes everything. My grandma always told me desserts need that little something extra, and here, it's definitely the condensed milk that turns an ordinary snack into something everyone remembers.

Fruit Options

Though blueberries are what I like best in this treat, other berries work great too. Raspberries add a nice tang that works really well against the sweet cheese filling. Blackberries look more rustic and burst with juice during baking. You can use strawberries if you dice them into blueberry-sized chunks. For a fun look, mix different berries together - try combining red raspberries with blueberries for a pretty red-and-blue dessert during summer holidays.

Make Ahead and Storage Tips

These blueberry cheese squares taste even better after sitting a while as the flavors blend together, so they're great to make in advance. Once they've baked, let them cool totally at room temperature, then wrap the pan tightly and stick it in the fridge for at least 4 hours or leave them overnight. They'll stay good in the fridge up to 5 days, but at my house they never last that long. If you want to keep them longer, cut them into squares after cooling and freeze them wrapped up separately for up to 3 months. Just thaw them in the fridge overnight when you want to eat them.

Serving Suggestions

These squares taste amazing on their own, but you can dress them up for special times too. Sprinkle some powdered sugar on top right before serving to make them look fancy. For a real treat, warm them slightly and add a tiny scoop of vanilla ice cream or some whipped cream. I like adding a fresh mint leaf for color and a bit of freshness. They go really well with coffee or tea for a snack, or with a sweet wine after dinner.

Frequently Asked Questions

→ Can I use frozen blueberries instead of fresh?

You bet! Frozen blueberries work just fine. Don't bother thawing them first - just toss them frozen into the cheese layer. You might want to bake them a bit longer, maybe 2-3 minutes more, since frozen berries tend to make things wetter.

→ Can I substitute raspberries for blueberries?

For sure! Like we mentioned in the ingredients, raspberries taste great too. You can also try cut-up strawberries, blackberries, or even mix different berries together for something different.

→ How long do these bars stay fresh?

When you put them in an airtight container in the fridge, these bars will last up to 5 days. They actually taste even better on day two after all the flavors have gotten cozy with each other.

→ Can I make these bars ahead of time for a party?

These bars are totally party-ready. You can make them 1-2 days before your get-together and keep them cold. Cut them into squares right before serving if you want nice clean edges.

→ Can I freeze these cream cheese bars?

They freeze really well. Let them cool completely, cut them up, and freeze them flat until they're hard. Then you can stack them in a freezer container with some parchment paper between layers. Just let them thaw in the fridge overnight before you want to eat them.

→ What can I use instead of quick oats?

If you only have regular rolled oats, you can blend them for a few seconds in a food processor to break them down a bit. Or you can just use the rolled oats as they are, but your crust and topping will be a little chewier that way.
