Easy Lemon Blueberry Cake Bars (Upgraded Boxed Cake Mix)

Making a fancy looking dessert doesn’t have to be hard. By using a ready made boxed cake mix as my base and adding in a few extra ingredients, I was able to take this basic cake from bland and boring to something truly delicious.

Cutting corners isn’t always a bad thing! Sometimes life gets busy and you can still make a great dessert without compromising on extra time and work.

I guarantee that whoever you make this cake for will be delighted with the rich lemony flavour paired with the delicious baked blueberries. I bet they will never guess that this pretty dessert started in a box.

Start off with a box of lemon cake mix. Ignore the directions on the back of the box and add in 3 eggs, 1/2 cup melted butter, 1/4 cup water, 1/4 cup lemon juice, instead.

Once everything is mixed nicely stir in 1 cup of plain yogurt and 1 cup of fresh blueberries. Adding yogurt to the cake makes it slightly denser, which is perfect when you are making cake bars.

Pour the batter into a well greased baking dish and bake in the oven at 350 for 45 minutes.

While the cake is baking you can prep the icing. Whisk together 1 container of white icing with the juice and zest of 1/2 a lemon. Set aside.

Once the cake has finished baking, remove it from the oven and let cool.

Flip the cooled cake over onto a parchment lined baking sheet.

At this point you can ice the cake as normal. However I like to make mine look a little fancier, so I prefer to cut the cake up into bars and ice them individually.

Spoon on some of that delicious icing and garnish with some lemon zest and a few fresh blueberries.

Enjoy!
