Lemon Curd Shortbread Crumb Bars

It’s finally time for spring baking and these delightful Lemon Curd Shortbread Crumb Bars will be the hit of the season. 

It’s finally starting to feel like spring around here which makes me so happy. It’s been raining for weeks but the sun is shining today and all the flowers and trees are blooming. It’s not quite short-sleeve weather yet but I can feel it coming. Hallelujah.

And I feel like we can officially pull out all the spring flavors. After all the heavy, hearty dishes of winter, it’s so nice to break out the grill and all the happy, light ingredients.

I mean, I love a lasagna or pot roast as much as the next guy but sometimes you want something light and refreshing. Am I right?

When I think of Spring flavors my mind automatically goes to lemon. It’s so refreshing and zingy, all the things I love in dessert.

I prefer a citrus dessert to something rich and chocolatey any day of the week so when I teamed up with Bob’s Red Mill to create the ultimate spring baking recipe using their Organic Unbleached White All-Purpose Flour, I knew it had to involve lemon.

After some brainstorming, I came up with these Lemon Curd Shortbread Crumble Bars and let me tell you, they did not disappoint. Unless you’re disappointed that I ate almost the whole pan without sharing….sorry, not sorry.

These bars start out with a super simple shortbread cookie recipe that requires 4 ingredients. Yep, you read that right.

The cookie dough doubles as the crust and the crumble in this recipe, making it even simpler. When you are using so few ingredients, you want to make sure they are quality so that the dessert and flavors can shine.

So when it comes to baking these bad boys (or anything in my kitchen), I reach for Bob’s Red Mill Organic All-Purpose Flour. It isn’t enriched with any additives or ingredients that you can’t pronounce which is really important to me when I’m feeding my family.

It’s also a high protein flour which is what professional bakers use so you know you are going to yield bakery quality results. So you can bake your own treats, using ingredients you know and your family will think you stopped by the local bakery. Winning.

You take that delicious shortbread dough and press some of it into an 8×8 pan and parbake it. Meanwhile, make the homemade lemon curd (or take the lid off the jar of the store bought stuff if you ain’t got time for that).

Once the crust is ready, you spread it with that light, zingy lemon curd and then mix in some rolled oats and coconut into remaining shortbread dough before crumbling it over the lemon curd.

Back to the oven it goes until the crumble is golden and the lemon curd is bubbly and gooey and all around wonderful.

I seriously could not keep my mind or my hands away from these bars. Like I said before, I am a big fan of citrus desserts and these are my new official favorite. They would be perfect for the upcoming holiday, a backyard picnic or a BBQ with friends.

Lemon Curd Shortbread Crumb Bars

Lemon Curd Shortbread Crumb Bars are made using Bob’s Red Mill Unbleached White All-Purpose Organic Flour and are perfect for Spring baking.
Course: Dessert
Cuisine: American
Keyword: crumb bars
Yield: 16 2-inch squares
Author: Meg’s Everyday Indulgence


For the Lemon Curd:

  • 3/4 cup fresh lemon juice (4-6 lemons)
  • Zest of 1 lemon
  • 3/4 cup granulated sugar
  • 3 eggs
  • 1/2 cup unsalted butter, cubed

For the Shortbread Crust and Crumble:

  • 1 cup salted butter, room temperature
  • 1 cup powdered sugar
  • 2 cups Bob's Red Mill All-Purpose Flour
  • 1/4 cup sweetened coconut
  • 1/4 cup old-fashioned oats
  • zest of one lemon


  • Preheat oven to 350 degrees F. Line an 8×8 pan with foil and set aside. First, make the lemon curd. Bring an inch of water in a large saucepan to a simmer. In a bowl that fits on the saucepan but does not touch the simmering water, whisk together the lemon juice, lemon zest, sugar and eggs. Whisk constantly until the mixture thickens and coats the back of a spoon (this can take between 10 and 30 minutes). Add the butter, one cube at a time, stirring until it has melted before adding the next. Once all the butter has been added, place in the refrigerator for 15 minutes to cool slightly and set up.
  • Meanwhile, make the shortbread crust. Cream the butter in a stand mixer. Add the powdered sugar, flour and lemon zest and mix until combined. Press 1 1/2 cups of the shortbread dough into the prepared pan. Bake for 12 minutes. Refrigerate remaining dough until ready to use.
  • Spread 1 1/2 cups lemon curd (you’ll have a little leftover) over the parbaked crust. 
  • Remove the remaining dough from the refrigerator and stir in the coconut and old-fashioned oats. Crumble into pea-size pieces over the lemon curd. Bake for 25 minutes, until the crumble is slightly golden. Cut into 2-inch squares and keep refrigerated in an airtight container.

Not only do I love Bob’s all-purpose flour but I always have their coconut, chia seeds, gluten-free baking flour, rice flour, almond flour and oat flour on hand. The list probably goes on but those are the Bob’s products I always have in my pantry to create wholesome food for the family.

    I cheated a bit- I had a jar of pre made lemon curd that I needed to use. So, when I happened upon this recipe, I thought I’d give it a try.
    My hubby loves lemon meringue pie and lemon bars. I just knew he would like these too.
    It’s an easy recipe to follow. The shortbread was tender, yet crisp. Very nice combo without being overly sweet.
    Turned out great!

  2. I’m so glad to hear they turned out well Jennifer! And thanks for letting me know they are successful with premade lemon curd, that’s definitely a great shortcut! Have a great day!
