Lemon Oreo Tart

Have you ever tried lemon and chocolate together?

Until a few months ago, I did not think lemon and chocolate went well together. When anyone suggested this flavor combination to me, I would always tell them that those flavors don’t go well together. If you are thinking that as well, this recipe will change your perspective!

Have you ever tried lemon and chocolate together? This Lemon Oreo tart features a chocolate cookie crust filled with a luscious, tart lemon custard filling. With both lemon juice and lemon zest this tart is full of lemon flavor and will have you going back for more!/>

My boyfriend and I were ordering dessert in Portugal when we saw “lemon oreo thing’” as one of the dessert options. Intrigued, we ordered it along with another dessert since one dessert is obviously not enough to share.

When it came out it was essentially a lemon tart with an oreo cookie crust! I immediately dove in and was hooked. The creamy and tart lemony filling surprisingly went very well with the chocolate cookie crust. Ever since then, I have been determined to recreate this dessert.

To recreate this tart I began with a chocolate cookie crust. For this you can use any type of chocolate sandwich cookies. To make the cookie crumbs, place the whole cookies (don’t take out the crème filling) in a food processor until they resemble fine sand.

Mix the cookie crumbs with melted butter and press into a tart pan. Bake at the specified temperature, then let cool.

Quick tip: If the crust puffs up do not worry. When cooling it will come down and form a crust with plenty of room for luscious lemon custard filling 🙂

The filling for this Lemon Oreo tart, adapted from Food and Wine Magazine, is an easy lemon custard. It gets its strong lemon flavor from both lemon juice and lemon zest.

Begin by mixing eggs, egg yolks, sugar, lemon juice, and lemon zest in a medium saucepan over medium heat. Whisk constantly until mixture thickens and coats the back of a spoon, ~5-8 minutes.

Take the saucepan off the heat and slowly add the cubed butter, whisking until smooth. If lumps remain, pass custard through a sieve. Pour custard filling into cooled cookie crust.

Refrigerate for at least 3-4 hours although the tart sets best if it can set overnight. Remove tart ring and top with whipped cream.

Quick tip: To remove the tart ring from the tart there are two ways to do this. One way is to put the tart on your hand and remove the ring. Another method is to place the tart on an upside bowl. Then gently nudge the tart ring off the tart.

I believe the second method is easier but either way will work!

Although this dessert looks stunning and will definitely impress your friends and family, it is relatively easy and definitely something that anyone can master!

Serve and enjoy 🙂

    1. Yes definitely, that’s a great comparison! I haven’t tried lemon and chocolate in other applications but this one is definitely a good start 🙂

    1. Thank you and it definitely is! I love baking with lemons and all the fresh fruit this time of year!

  1. looks yummy! I never had the mix of chocolate and lemon,but I am going to make this soon.

  2. Ohh this looks so yummy! Do you think it would work with lemon oreos? Or would the result be too lemony? My poppop who recently passed away LOVED lemon oreos and I’d like to make something like this for my family in honor of him 🙂

    1. Thank you! I never thought of using lemon oreos but I am sure it could work. To see if it is too lemony you would have to try it. If you are worried about that, you could also try making the crust with half lemon oreos and half graham crackers or some other mild flavored cookie. I have not tried using two types of cookies, but I do not see why it wouldn’t work. I hope this helps!

  3. WOWZERS, this looks so intensely yummy! Thanks for sharing, I’ve never tried to make a dessert like this, but perhaps I will.



    1. Thank you! I know it may look complicated but it is in reality pretty easy, especially for how stunning it looks!

  4. I never would have thought to put lemon and Oreo together, but just this afternoon when I went to get ice cream, the lady at the counter told us that lemon Oreo shakes are really good. This seems like the same idea!

  5. Sometimes the strangest combinations are the best. My best friend is in love with everything lemon, I’ll have to make it for her.

    1. Yes this definitely has a good combination of sweet and tart. It is also not very difficult to make, enjoy!
