I went a little more fancy and browned the butter to add extra nutty flavour to the shortbread. I mean, when you’re stuck inside, you have more time to make it uber-delicious , so why not? My sister (who does not eat a lot of dessert) loved it!
*Good To Know*
- How far in advance can I prepare the bars?
Note that the bars need at least 3 to 4 hours of chill time in order for the filling to set. Plan to make these in the morning or the night before. - Room Temperature dairy ingredients.
This seems like an unnecessary step but makes a big difference when utilizing dairy at room temperature vs. cold from the fridge. The reason for this is when mixing ingredients at room temperature the dough will mix/blend better together more easily for a smoother batter or dough without clumping. Plan ahead and leave ingredients on your counter overnight or at least 30 minutes to 1 hour ahead. - Browning Butter, Is this necessary?
No it’s not. I browned 1 stick butter to deepen the crust flavour (aka. hint of nut without actual nuts). Feel free to brown both sticks of butter if you prefer and add an even deeper level of nutty flavour to your crust - Eggs – Crack eggs into a mug or measuring cup. I like doing this so it’s easier to add 1 egg at a time to the filling (also easier to remove excess shell). Pro tip: crack egg against countertop instead of side of bowl. It reduces the chance of small egg shells dropping into your cup when you crack it.
How to make shortbread
Making shortbread is fairly simple. If you prefer not to brown the butter, you can skip this and microwave the butter to melt. Remember not to overdo it as we just want it to be soft enough to mix into our flour. After combining the ingredients with a spatula (I preferred to do this by hand since it was quick and required less cleaning, however using a stand mixer with paddle attachment is ok too) the dough will be thick and dense.
The key is to under bake your shortbread as it will be baked a second time with your filling. Remember to set your timer for this! I almost forgot to set mine and that would have made for an overdone shortbread crust.
At this point, the smell of the shortbread- citrusy goodness was so inviting. I couldn’t wait to try these babies…BUT… now comes the crucial part. Chill Chill Baby!
Allow your baked shortbread bars to cool then cover with plastic wrap (brush out air bubbles) and place in the refrigerator to chill completely.
Your patience will be rewarded with these wonderful citrusy treats. Better guard them, chances are there won’t be a lot of leftovers by the end of the day!
Orange-Lime Brown Shortbread Bars
Ingredients
Crust:
- ½ cup butter, melted
- ½ cup browned butter, slightly cooled
- ½ cup white granulated sugar
- ½ teaspoon salt
- 2 cups all-purpose flour
- 1 teaspoon lime zest
- 1 teaspoon orange zest
Filling:
- ½ cup orange juice, freshly squeezed
- ½ cup lime juice, freshly squeezed
- ¼ teaspoon salt
- 6 large eggs, brown or white
- 2 cups white granulated sugar
- ⅓ cup all-purpose flour
Decoration:
- ⅓ cup powdered icing sugar
INSTRUCTIONS
Crust:
- Preheat oven to 350°F or 176°C. Use a rectangular 9 x 13 inch baking pan with a 3 inch height (or casserole dish will work too), line with parchment paper on the sides and bottom.Pro Tip: Use softened butter to brush the sides and bottom of the pan prior to placing parchment paper to keep the paper in place and fold down the extra overhang on the outside of the pan. (for easier lifting)
- Add 1 stick of butter to a small saucepan on medium heat and stir continuously until all of the butter is melted. Keep stirring until it starts to bubble and brown bits appear on the bottom of the pan (about 3 – 4 minutes). Remove from heat and stir another 30 seconds. Set aside to cool.
- Melt 1 stick of butter in the microwave ( 30 to 45 seconds). In a large bowl, combine melted butter, browned butter, sugar, salt, flour, lime and orange zest. Mix thoroughly with a spatula until dough appears to be dense and thick.
- Press shortbread dough firm and evenly into prepared pan. Place on middle oven rack and bake for 20 minutes or until edges are very lightly browned. (key is to under cook because a second bake will be done with filling. Remove from oven (do not turn oven off) and set aside.
Filling:
- In a large bowl, whisk (by hand) together orange, lime juice, salt and eggs until well incorporated (2 minutes). Add sugar, flour and whisk until thoroughly combined. Pour over warm shortbread crust and bake uncovered for another 25 minutes or until the center no longer jiggles.
- Let cool to room temperature. Cover with plastic wrap by gently flattening against filling surface to remove any air bubbles and place in the refrigerator to chill for 4h or overnight to allow filling to set.
- When ready to serve, lift the shortbread out of the pan. Add confectioner's sugar to a small sieve and dust over entire shortbread. Cut into squares and serve with hot beverage of choice. Enjoy!
