And yes, they are 100% gluten free. No weird ingredients, no complicated steps. Just simple stuff you probably already have in your kitchen.

The crust comes together in minutes with almond flour and a couple of other basics. The filling is just as easy to mix up. Pour it over the crust, bake, and you are done.

Ingredients

For the Crust

1 cup Almond Flour
1/4 cup Powdered Sugar
1/4 cup Melted Butter

For the Filling

3 large Eggs
3/4 cup Granulated Sugar
1/3 cup Fresh Lemon Juice
2 tbsp Gluten Free All Purpose Flour
1/2 cup Strawberry Puree

How to Make

Step 1

Preheat the oven to 350F and line an 8×8 inch baking dish with parchment paper.

Step 2

In a bowl, mix the almond flour, powdered sugar, and melted butter, then press the mixture evenly into the bottom of the baking dish.

Step 3

Bake the crust for 12 minutes until lightly golden, then leave the oven on.

Step 4

While the crust bakes, whisk together the eggs, granulated sugar, fresh lemon juice, gluten free all purpose flour, and strawberry puree until well combined.

Step 5

Pour the strawberry lemon filling over the warm crust and bake for another 20 to 25 minutes until the center is set.

Step 6

Let the bars cool completely at room temperature, then refrigerate for 2 hours before dusting with extra powdered sugar and slicing.

Helpful Tips

Press the Crust Firmly and Evenly

When you press the almond flour crust into the baking dish, use the flat bottom of a glass or a measuring cup to pack it down tight. If you just use your fingers, you’ll end up with some spots thicker than others and the crust won’t bake evenly.

Pay extra attention to the corners and edges of the dish. Those spots tend to get neglected and end up too thin, which makes them overbake and taste dry while the center stays underdone.

You want a compact, even layer across the entire bottom. A well-pressed crust holds together when you slice the bars later instead of crumbling apart.

Use Real Fresh Lemon Juice

Squeeze your lemons by hand or with a citrus press instead of using the bottled stuff. Fresh lemon juice has a bright, clean flavor that bottled juice just can’t match, and you’ll really notice the difference in a recipe like this where lemon is one of the main flavors.

You’ll need about 2 to 3 medium lemons to get the 1/3 cup of juice. Make sure to strain out any seeds and large pulp pieces before adding it to the filling so you get a smooth texture.

Make a Smooth Strawberry Puree

To make the strawberry puree, blend about 1 cup of fresh or thawed frozen strawberries in a blender or food processor until completely smooth. Then push it through a fine mesh strainer to remove the seeds.

Straining is an extra step but it’s worth it. The seeds can make the filling feel gritty, and removing them gives you that smooth, silky texture you want in these bars.

Measure out the 1/2 cup of puree after straining, not before. You lose a little volume when you strain, so starting with about a cup of berries makes sure you end up with enough.

Frequently Asked Questions

How do I make the strawberry puree?

Just blend fresh or thawed frozen strawberries in a blender or food processor until completely smooth. You’ll need roughly 1 cup of whole strawberries to get about 1/2 cup of puree.

If you want a silky smooth filling with no seeds, strain the puree through a fine mesh sieve before using it. This step is optional, but it does give you a cleaner texture.
