Blueberry Crumble Bars are an easy and delicious way to enjoy fresh blueberries this summer berry season! Frozen berries work just as well in these Blueberry Crumble Bars so you can enjoy this divine dessert all year long!
The inspiration behind this recipe:
Major storms recently blew through this part of the country. We were very fortunate–just a messy yard and the electricity was out for about 12 hours. Because of the storm, however, our kitchen refrigerator took a power surge and quit working a day later.
Thankfully, we have an old beast in the garage that nothing can kill so I scrambled and made room for everything out there.
Although I keep pretty good tabs on what we have in each refrigerator and freezer, I found several gallon-sized bags of blueberries we brought back from Wisconsin last summer I forgot about. Beautiful, big sweet Wisconsin blueberries!
Jessica Robinson, who is one of my food blogging friends, recently released her second cookbook: A Farmgirl’s Table. (Affiliate link.) Now, you know I don’t bake very often because it’s just my husband and me here and if I bake sweets, we eat them and we don’t need to eat them.
However, in Jessica’s cookbook was a recipe for Blueberry Crumble Bars I simply had to make! They looked so good!
The Blueberry Crumble Bars were absolutely wonderful and so easy to make!
Jessica’s cookbook is filled with farm-inspired recipes with beautiful food photography. Having grown up on a farm myself, this cookbook takes me back to my roots and the good, honest food I grew up with. The recipes reflect Jessica’s rich farming heritage. I love how she begins the cookbook by saying, “Not everyone is fortunate enough to grow up on a farm, but everyone can cook as if they did.”
A Farmgirl’s Table has solid classic recipes like these Blueberry Crumble Bars in addition to fun, creative spins on classics perfect for today’s cook.
My only suggestion is to refrigerate the Blueberry Crumble Bars. I wasn’t able to photograph them immediately and they started to soften up. They should keep a good week in the refrigerator–if they last that long!
Cookbooks are kind of my “thing” and I highly recommend A Farmgirl’s Table by Jessica Robinson!

This is a common dessert to have in my fridge. Who am I kidding, it’s often a meal for me. Easy, kid friendly. I also add an additional cup or so of berries. Frozen mixed berries are delicious in this recipe!!
Carol says
Hi, Kait, Thanks so very much and so glad you enjoy! This is one of my favorite desserts, too because it doubles as breakfast. Love your idea of doing it with mixed berries. Thanks again!
Terry says
Why would anyone have tapioca hanging around? What would I sub? Nevermind, I’ll find another recipe.
Carol says
Hi, Terry, I realize everyone is under a lot of stress these days. Not everyone may have any number of ingredients hanging around including blueberries but they would buy them. Tapioca is in the baking aisle just like a number of the other ingredients in this recipe. So sorry this won’t work for you. Hope you are staying well.

Carol says
Love that! Thanks so very much and glad you enjoyed!
Teresa C says
Carol, what an eloquent way to respond to an immature “cook.” I am excited to try your recipe because of the tapioca. I have used it in several other recipes and I love what tapioca adds to the consistency of a recipe!
Carol says
Hi, Teresa, I appreciate that! Thanks so very much and hope you enjoy!
