Keto Raspberry Lemon Bar Recipe

Today I’m sharing a simple and delicious Keto friendly lemon square recipe with a twist: Keto Raspberry Lemon Bars.  

Spring! It’s here, whether we believe it or not…

With how strange life feels these days with COVID19 and social distancing and isolating, it’s strange to think that the earth just keeps turning and the days keep going and the seasons are coming on schedule; all outside of what our human experience of it all is.

With the beginning of Spring, my favourite season, I’m definitely thankful for the longer days and extra light that we are getting each day.  My mind is beginning to turn towards the garden; I’m thinking that since I’m “homeschooling” now it would be great to plant a lush garden with the boys and teach them all about growing their own vegetables and fruit.  One fruit that I’ve always wanted to cultivate is raspberries.  I love raspberries! And with my husband and I following a Keto diet program for the past couple of months, raspberries are one of the lowest carb fruits there are.  Lemons are another!

If you think you can’t enjoy a fresh and delicious fruit-based desert on Keto then you have another “think” coming.  These Keto raspberry lemon bars and super easy to make, delicious, fresh and tart balanced by sweetness- perfect for spring.

These are a twist on traditional keto lemon bars that are baked in two stages.  The key is using fresh lemons – the flavour added by -true lemon zest and freshly squeezed lemons is impossible to replicate.  I used frozen raspberries for ease and cost savings and I would say the flavour is not compromised in the least by frozen berries.

These are best when you freeze them overnight after baking, then slice and keep in the fridge until serving. You can cut the keto friendly bars from an 8″X8″ pan into 9 squares, as I did, or even into smaller pieces (like 1/16) as they have such a fantastic sweet but tart, fresh flavour that you don’t need a lot to feel satisfied.

  • 1 3/4 cup almond flour separated
  • 1/2 cup unsalted butter melted
  • 3/4 - 1 cup Stevia or erythritol
  • 1/2 tsp vanilla
  • salt
  • 3 eggs
  • 3 lemons
  • 1/4 cup frozen raspberries


  1. Preheat the oven to 350 degrees.
  2. Line an 8" x 8" baking sheet with parchment paper.
  3. Prepare the crust by mixing the melted butter, 3/4 cup of almond flour, 1/2 tsp of vanilla, and 1/4 cup of stevia and then pouring into the baking dish.
  4. Flatten the crust dough and bake for 20 minutes.
  5. Take out and allow to cool for 15 minutes.
  6. While the crust is baking, zest 2 of the lemons and then juice all three lemons (carefully removing the seeds).
  7. Mix the lemon zest and juice with the rest of the almond flour, Stevia, and eggs, and a pinch of salt and whisk together.
  8. Pour the filling over the cooled crust and bake for 25 minutes at 350.
  9. As it's baking, put the frozen raspberries into a bowl and microwave for 45 second. Blend together to create a raspberry syrup.
  10. After removing the lemon squares from the oven, pour the raspberry syrup over the square and smooth with the back of a spoon.
  11. Allow to cool and then cover and place in the freezer for at least 2 hours, preferably overnight.
  12. Slice into 9 even squares, or 16 squares if you wanted smaller pieces. Serve cool, and keep in the fridge before serving.

    These look so good, my husband is fulltime keto and I hop on and off , being a food blogger makes it tough sometimes.(Im sure you know that lol) Thanks for sharing

  2. Can you make them with brown sugar? We do not have any stevia, can you get stevia in a crystal form like sugar? I have only seen it in small packages.
    I usually find artificial sweeteners have a bit of an aftertaste?
    Also right now with limited shopping i am not sure it is possible to find.

    1. Hi Penny,

      You should be able to make these with regular white sugar, that just means they won’t be keto. I bought my Stevia in the baking section at Walmart – the artificial sweetener is Erythritol. It says on my package that you use half the amount of Stevia as you would sugar. Hope that helps,

  3. Wow, these look amazing Krista! I love anything lemon, and Lord knows I’ll need to be doing Keto soon with all we’re eating and baking over here! Can’t wait to try these!
