Lemon Rhubarb Bars

  4.7 – 19 reviews  • Lemon Dessert Recipes

These lemon rhubarb bars have a wonderfully sweet yet tangy filling and a crispy sweet crust. They are also very addictive, so beware!

Prep Time: 20 mins
Cook Time: 1 hr
Additional Time: 20 mins
Total Time: 1 hr 40 mins
Servings: 24
Yield: 1 12×9-inch pan

Ingredients

  1. 2 cups flour
  2. 1 cup unsalted butter
  3. ½ cup white sugar
  4. 4 eggs
  5. 1 cup white sugar, or to taste
  6. 6 tablespoons all-purpose flour
  7. 2 cups chopped rhubarb, or more to taste
  8. 1 cup shredded coconut
  9. 6 tablespoons lemon juice
  10. 2 teaspoons vanilla extract

Instructions

  1. Preheat oven to 350 degrees F (175 degrees C).
  2. Mix 2 cups flour, butter, and 1/2 cup white sugar together in a bowl until crumbly; press into the bottom of a 12×9-inch baking dish.
  3. Bake in preheated oven until crust is light brown, 25 to 30 minutes.
  4. Beat eggs, 1 cup sugar, and 6 tablespoons flour together in a bowl until smooth; add rhubarb, coconut, lemon juice, and vanilla extract and stir to coat. Pour the rhubarb mixture over the crust.
  5. Bake in preheated oven until the fruit layer is set, 35 to 40 minutes. Let bars cool completely before serving.
  6. Depending on how much you like the taste of rhubarb, you can add more sugar or even less. If you don’t like rhubarb add two cups of sugar.
  7. The coconut can be a bit stringy so put into a food processor to chop into finer pieces, if you’d like. This option can also be applied to the rhubarb for a smoother consistency overall.

These are spectacular with a pretty presentation. This recipe is one of my new favourites! The filling changes per other comments are good & as follows: – 4 cups thinly-sliced rhubarb – 1.5 cups sugar – 1.5 cups sweetened shredded coconut Add: – 3-4 tbsp finely grated lemon zest – 1-2 tsp salt Use a parchment lining & light spritz of cooking spray on the pan for easier removal. Cooking times need to be shorter, too: crust 20-25m (until just the edges are brown) & filling 35-40m (until fully set, not jiggly). Let cool & refrigerate overnight before cutting into bars. I like the texture & visual appeal of the sliced rhubarb & long coconut, so suggest leaving them as is. If your rhubarb is too thick, try slicing the pieces in half instead of mashing them in a food processor. Better yet, just use fresh rhubarb & slice into 5mm thickness for faster cooking.

I made these following the recipe exactly and it was fantastic. Then I substituted the rhubarb out for 2lbs of blended strawberries and it was just as good. Feeling daring, I ultimately substituted 6 large bananas for the rhubarb and I am in love with this recipe! I’m going to keep subbing fruit and recommend y’all try it too!
Michael Schneider
I added more rhubarb because we are rhubarb fanatics and a bit more sugar. I also added fresh lemon slices instead of the juice…. just because I had a lemon I needed to use up. But neither of those items really changed the dish at all and it was fantastic! Easy to prepare and super easy to feast on ! Now look for the Blueberry Square they sent the other day. Another delicious dessert. This one I doubled and shared ! Delish ! Well, I shared the lemon dessert as well. I seem to do that a lot ! Now on to rhubarb slice. So much fun !

This was fabulous! I added one extra lemon and instead of sugar I used icing sugar for the crust to mimic a true shortbread crust! Loved it and it was so easy!

I followed the suggestions and finely chopped the rhubarb and the coconut. Because I was taking this on a family vacation (where there was an oven), I did some prep work to simplify things in the kitchen. I baked the crust in a 9 x 13 before hand and added the filling and baked it at the time share. I added the zest of one small lemon to the crust – I wanted to make sure that there was enough sour. Everyone enjoyed it. In the ;9 x 13, it made 12 nice sized bars. I did take the wrapper of the butter and grease the pan, just to ensure no sticking…pieces came out great!

This was quite good. I made this in a proper 9×13 pan, lined with parchment. It’s a nice thick crust to support the topping. I’d suggest cutting the first bake of just the crust to 20 minutes max, and I think this recipe is remiss in not including the use of the lemon’s zest for true lemony flavour. I added the zest of 1 lemon in the egg/sugar/flour mixture and would highly recommend that.

I love lemon bars and rhubarb so had to try this. Followed the recipe as written except I did as someone had suggested and put the chopped rhubarb (~34” chunks) in the food processor and pulsed it a few times to make the chunks smaller. Mine turned out with a little more red than the photo with the recipe. It wasn’t as tart as I expected so next time I’ll add more lemon juice. Took it to a meeting at church and received many nice comments as well as requests for the recipe.

I love this recipe, its an awesome way of getting rid of all your rhubarb, and it’s so tasty!!!!!!

Lemon, coconut and rhubarb on a shortbread crust….YUMMY!!
Michael Hall
These turned out very well. I did run the rhubarb and the coconut through the food processor as recommended and I don’t think they’d have been as good if I hadn’t. I only gave four stars instead of five because digging out the food processor is a pain and there are easier bar cookies out there.

I really liked the lemon flavor with coconut and start rhubarb. The cookie like bottom was good. I added a handful of chopped strawberries that needed to be used. Will make again
William Brown
I really liked this but I changed a few things so I can’t give it five stars as is. I added sweetened shredded coconut and only about 4tbsp lemon which came out as the perfect sweetness! I also used frozen rhubarb and included the juice from the chopping. I ended up with a 9×13 pan and about 14 mini muffins.
Karen Lopez
Though the crust was tasty, it was too thick for the amount of fruit – and I used 3 cups of rhubarbs and several cut up cherries. But it tasted good and the recipe has potential. Next time, I’ll use more rhubarb, more lemon or add a bit of lemon oil. The reviewer who cut back each of the baking times by 5 minutes was probably right; I had difficulty getting some of the bars out of the pan. I might put the coconut into a food processor to chop it into finer pieces also. BTW, that photo doesn’t look as if a 9″ X 12″ pan was used!

I made this and loved it. I did the following: used Coconut Palm Sugar in the crust, white sugar in the filling, finely shredded coconut (the texture worked fine for my tastes), fresh squeezed lemon juice (what I had), approximately 3 cups of sliced, fresh rhubarb and added about 2 T of my own honey to the filling (based on sweetness comments in the reviews). I baked the crust for 25 minutes. I baked the filled crust for 30 minutes at 350 and 15 minutes at 250 with the pan covered with foil. I wasn’t sure if the rhubarb was cooked enough and wanted to be tender, not crunchy. I can’t wait to make it again. I may switch out the lemon juice for pineapple juice and add crushed pineapple. Thank you for a yummy new dessert.

I also halved the recipe , but still doubled the rhubarb (4 c.) and upped the sugar (to 1 1/2 c.) and cooked it in a big pie tin and so it took slightly longer to set. I loved the shortbread crust in contrast to the tart creamy filling. The coconut and rhubarb go great together…maybe next time I will double that too. The lemon mellowed and I think this is better the second day. This is going to be a regular rhubarb treat. Thanks from a rhubarb lover.
Tonya Klein
Delicious! Great crust, tart, fresh filling that set up beautifully for us even though we couldn’t wait and cut slices right away. Our rhubarb was green too and we didn’t have quite enough, so we threw in a few frozen cherries and they added a pretty touch of color. Thanks for sharing!
Patricia Snyder
I didn’t want a full 9×13 pan so I halved the recipe. Although I have the green variety of rhubarb, it still made a lovely presentation using my tart pan. As is my norm, I doubled the amount of fruit, therefore I increased the sugar by 50%. It came out great but I may decrease the amount of rhubarb by a smidgeon the next time. I thought this was actually better the next day. It’s a great recipe. Thanks for sharing!
