The name of the game in my kitchen is “don’t make things harder than they have to be.” Life has a way of doing plenty of that on its own. Baking yummy things should never be a headache.

It is with that mentality that I learned to embrace boxed cake mixes years ago. Obviously, I know HOW to make a cake from scratch…

…but cake mixes sure do put the “easy” in easy baking recipes. Take these cake bars as proof.

They start with a simple yellow cake mix that you doctor up a little with some additional brown sugar, eggs, and vanilla. Then, you create a simple filling (that will remind you of blueberry pie filling, only better) from fresh blueberries and sugar that gets baked inside each of the cake mix blueberry crumble bars.

I call them a bar because I personally would eat them out-of-hand, like one of my popular brownie recipes:

But you could also eat them similar to a cake by warming them up a bit in the microwave and topping them with a scoop of vanilla ice cream.

Easy to make, eat, and enjoy! ~Regan

Description

An easy dessert recipe that starts with a dry cake mix. The whole family will love this simple dessert.


Ingredients

  • Cooking spray
  • 2 cups fresh blueberries or other fresh berries (or frozen)
  • 1/2 cup white sugar
  • 1 (15.25-oz.) pkg. classic yellow cake mix, vanilla cake mix or lemon cake mix
  • 1 cup melted butter
  • 1 cup dry old-fashioned oats
  • 1/2 cup packed brown sugar
  • 2 large eggs, at room temperature
  • 1 tsp. ground cinnamon
  • 1 tsp. vanilla
  • 1 tsp. lemon zest (optional)
  • 1/4 cup powdered sugar (optional)
  • 1 Tbsp. fresh lemon juice (optional)

Instructions

  1. Pre heat oven to 350 degrees Fahrenheit. Line a square baking pan or baking dish with parchment paper or aluminum foil, leaving a 1-inch overhang over opposite sides; coat bottom of the prepared pan with cooking spray, and set aside. Combine blueberries and granulated sugar in a small bowl; set aside.
  2. Add cake mix, butter, oats, brown sugar, eggs, cinnamon, vanilla, and lemon zest, if desired, in large bowl of a stand mixer. Beat at low speed 1 minute, stopping to scrape down sides as needed. (Batter will be thick.) Spoon a little over half of the mixture (2 cups of batter) into prepared pan; carefully smooth to edges of pan. Top with an even layer of the blueberry mixture. Drop remaining batter by tablespoons evenly over top of batter, and carefully smooth with a small offset spatula or back of spoon. (There will be spaces that remain uncovered by batter.)
  3. Bake in preheated oven until top of the bars are browned and set, about 45 minutes baking time. Meanwhile, combine powdered sugar and lemon juice, if desired to use as glaze.
  4. Remove bars from oven; place on a wire rack, and let cool at least 30 minutes. Carefully lift bars from pan using parchment paper overhang or ends of foil. Cut into bars, and store in airtight container or cover tightly with plastic wrap.
