Happy Mother’s Day! Not only is the following dessert a favorite of my mother, the timing is ideal, as rhubarb’s short season is upon us. If you haven’t baked with rhubarb before, this recipe is a very good starting point.

I am not sure how many people would offer up rhubarb bars when asked their favorite dessert, perhaps favoring something including the words chocolate or ice cream. The first time I made these, my husband, who did not grow up eating rhubarb, only ate one because he thought he should, kindly acknowledging my effort.  

I remember well the look on his face as he took his first bite. He sort of went slack-jawed and uttered a simple, “These are amazing.” My kids love them too.

Over time, I have made tweaks to the recipe, adding ground ginger to enhance the flavor and slivered almonds for crunch. For the crust, I often use coconut oil instead of butter, which creates a crisp, delicious base that is a perfect contrast to the slightly gooey top. You may use butter, if you prefer. 

To boost the coconut flavor, I usually add some shredded coconut. But never fear, if you are not a coconut fan, this may be omitted.

Rhubarb Bars

The sweet-tart flavor and slightly gooey filling are balanced by a crisp crust, making these bars a must when rhubarb is in season. The bars are delicious served warm or room temperature with a scoop of ice cream and will firm up a bit after resting overnight in the fridge.
Prep Time 20 minutes
Cook Time 50 minutes
Total Time 1 hour 10 minutes
Yield 12 servings

Ingredients

For the crust

  • 1 cup (127g) all-purpose flour*
  • ¼ cup plus 2 tablespoons (45g) confectioner's sugar
  • ½ cup (112g) extra virgin coconut oil or butter, room temp (with an option if cold)

For the filling

  • 2 large eggs
  • cups (288g) granulated sugar
  • ½ cup (42g) shredded, unsweetened coconut (optional)
  • ¼ cup (32g) all-purpose flour
  • ¼ teaspoon ground ginger
  • ½ teaspoon kosher salt
  • 2 cups (~8oz) diced rhubarb
  • ¼ cup (22g) sliced almonds
  • Optional for serving: vanilla ice cream

Instructions

  1. Prepare the crust: Preheat the oven to 350℉. In a mixing bowl, combine the crust ingredients with a fork. The dough will be fairly stiff. Press into the bottom of a 7×11 or 9×9 pan. (No need to grease, but you can line the pan with parchment for easier removal of the bars, if desired). If your butter or coconut oil is cold and hard, combine the flour and sugar, and then cut in the butter until the mixture resembles coarse crumbs. Press into pan as directed above. 
Bake at 350℉ for 13-15 minutes, or until just cooked; the crust will be pale, not golden brown.
  2. While the crust is baking, prepare the filling: 
Beat the eggs, and then add the sugar, optional shredded coconut, flour, ginger, and salt. 
Fold in the rhubarb and almonds. (Tip: I used the same bowl I mixed the crust in. No need to wash, just scrape it out well.)
  3. Spoon the filling over the hot crust and carefully spread into an even layer. (Pro tip: For prettier bars, place some extra sliced almonds on top of the bars before baking.) Bake for 35-38 minutes more, or until the center is set and the edges are very lightly golden. Cool completely before cutting into bars.
  4. Storage and serving options: I store leftovers, covered, in the refrigerator, where they will last for the better part of a week. Note: The bars firm up and cut better once chilled, although we often enjoy the bars on the first night, when they don't cut as well but are delicious with a scoop of vanilla ice cream!

Notes

*Need a gluten-free recipe? I have made these bars many times with a cup-for-cup, gluten-free flour blend, and the outcome is excellent. Use your favorite brand or my All Purpose Gluten Free Four Blend recipe HERE.
Want to freeze rhubarb for later use? Raw rhubarb freezes well, so I often chop the washed and dried rhubarb into the size I will want to use later (i.e., diced, chunked, etc.) and freeze it in a single layer on a baking sheet. Once frozen, I transfer to a zip-top bag or airtight container and freeze for 8-12 months. Typically, rhubarb does not need to be thawed before using it in recipes. 

Last but not least, I thought you might enjoy an ancient iPhone photo of these yummy bars… 😜

    My husband really does not like rhubarb, however he really liked these bars. I basically followed the recipe except I chopped the almonds in my food processor then threw in the rhubarb for a few seconds as I hadn’t chopped it very fine. I will most definitely make this again. It is so good.

    1. Hi Moira, I’m delighted these were an unexpected hit with your husband and that you’ll be making them again!

  2. These were a major hit at our church potluck yesterday – – made by a friend who sent everyone the link because we all wanted the recipe 🙂

    1. Such wonderful feedback. Thank you for letting me know!

  3. […] a number of other rhubarb recipes on this blog that have become family-favorites in our house, from coconut rhubarb bars to cobbler, rhubarb streusel muffins to baked […]

  4. One last thing – I didn’t have slivered almonds, so I coarsely ground up about a 1/4 cup of almonds in the food processor. It worked great!

  5. Just made these today, and everyone loved them! The coconut and ginger was a nice change-up. I do want to share a couple of tips that I learned in the process.

    Because my coconut oil is in the cupboard in California, it was melted, and that turned the “dough” into a batter. I was really worried about it and tried to add more flour, but it didn’t do anything. The batter actually spread better and was easier to deal with, but it was unexpected given the directions. Just know that batter is OK.

    If you have a gluten free flour mix that you already use, you’ll need to add in salt and xanthan gum separately to the recipe. My flour mix is just brown rice flour, potato starch and tapioca flour. Once I added that in, I put in 1/4 teaspoon xanthan gum and 1/8 teaspoon salt.

    We like our rhubarb much tarter, so I did 2 cups of rhubarb to 1/2 a cup of sugar. That was a perfect ratio for us. Hope that helps someone else.

    1. Thank you for the great feedback, Tanya. I’m thrilled you enjoyed these and that you took the time to share your tweaks. The gluten-free blend that I linked does have xanthan gum, but your point is a good one…as is the feedback on the melted oil. Thanks again!

    the coconut crust still ended up being my favorite part of these….so I just made another batch of crust only, added a 1/2 cup of coconut and made cookies out of it.Baked at 350 for 15 min. Coconut shortbread, Yum!

    ok the filling DID make it onto the bars. I know it says that the coconut is optional…but I think that is what makes these extra good/something different. I don’t think the coconut is optional!

    1. I am glad you made it to the final step! I list coconut as an option as I know there are some who are not a fan, and I initially created this recipe without it. As for me, I do prefer it, too!

    I didn’t even get to the filling yet. I just made the crust. Pulled this one up as I got coconut oil cheap at Marshalls recently. OMG the crust is good. Might not even need the filling,,,,might just eat the crust like a coconut cookie.

    1. I love your comment! And I agree…there is something magical about that crust. This is one of those recipes that made me really happy when I figured it out: )

  10. […] week, I posted a family favorite recipe for Ginger Almond Rhubarb Bars.  In the archives of this blog, I have a long-loved recipe for Strawberry Rhubarb Sauce.  I have […]

  11. This sounds delicious….. I am going out to buy some coconut oil… Have been thinking of trying it so this will be perfect…

    1. I hope you enjoy them, Marlys! Butter may be substituted, by I do think the coconut oil adds a little something special.

  12. These look amazing, cant wait to try this. As for the coconut oil it makes a huge diffrence if you buy the extra virgin coconut oil. If it is not it has no flavor and is more like using crisco. Extra virgin is hand pressed and is so much better for you. I have to order from the internet or go to larger citys that have organic markets to get mine but its worth it.

    1. Thanks for the comment and the great tip, Coni! I always buy the extra virgin coconut oil myself so I appreciate the feedback regarding the alternative. I use this oil more and more and keep finding great new uses for it.

  13. Looks wonderful sweetie! I picked up a jar of coconut oil the other day and was tempted to buy it, but put it back. I’m going to buy it next time I go to the store. Thank you for sharing on Thursday’s Treasures Week 34. See you next week. <3 and hugs! http://www.recipesformyboys.com/2012/05/thursdays-treasures-week-34.html open all week

    1. I am using coconut oil more and more, Debi. I think you will like it!

  14. I LOVE this recipe- all the different flavors sound so good together! I also am just getting into using coconut oil more seriously and look forward to trying this with some of my rhubarb and coconut oil! Thanks for sharing.

    1. I have really gotten into using coconut oil, too, and I was so pleasantly surprised by how crisp and yummy it made this simple crust. It reminded me of shortbread. Thanks for the thoughtful comment!
