Blueberry Squares

I've made these easy berry squares for many, many years and they never fail to bring raves from people of all ages. I'm always being asked for the recipe! When things get really busy, I like the convenience of being able to make this fuss-free treat a day ahead of time. —Barbara Robbins, Chandler, Arizona

    Good dessert, I used the marshmallow fluff instead of the marshmallows. I thought it made for a better texture. Also, if you are in a rush store bought pie fillings could be used instead of making your own.

    This was very good, but in my opinion, 3 Tbsp of lemon plus lemon zest is just too much for this recipe. I only used 2 Tbsp and still thought the lemon took over the flavor in this recipe. I would make this again, but just use 1 Tbsp of lemon juice in order to highlight the star of the show, blueberries!

    We thought it was very good. Would like to try it with cherries also raspberries.

    Not bad. I used frozen blueberries instead of fresh, so they may have come out more tart than intended. Besides that, the flavors in the bar are balanced really well. The only thing I'm not sure about is the marshmallows. They made the texture a bit weird. It sounds like it's hard to make, but it's actually pretty easy.

    My family and I thought this was terrible. The only reason we can give it 2 stars is because our neighbors who were over for dinner liked it.

    I would do a graham cracker crust in my opinion. I didn't like the vanilla wafers but the blueberry topping was just awesome! Liked the marshmellows.

    I've been making this since its publication in 2007, and it's one of my favorites. I love blueberries, so I'm always glad to find a good recipe that features them. I am not a marshmallow fan, so I was skeptical at first, but in this recipe, I love them.

    I thought it was just okay. Not sure if I'd make it again. 4 stars because my husband really liked it.

    Great recipe. I was a little concerned about how the marshmellows would work, but they blended in well and they added a different kind of texture when you are enjoying the dessert.
