Preheat your oven to 325°F (160°C). Line a 9x9 inch baking pan with parchment paper, leaving a little overhang on the sides for easy lifting later.
In a spacious bowl, combine the almond flour, keto sweetener, baking powder, and sea salt. Give them a good whisk to ensure everything is well mixed and lump-free.
Pour in the melted butter, the whole egg, the extra egg yolk, fresh lemon zest, lemon juice, and pure vanilla extract. Stir everything until a lovely, thick dough comes together.
Gently fold in your finely diced strawberries. Be careful not to crush them too much; we want them distributed nicely throughout the blondies.
Transfer the thick dough into your prepared baking pan. Using your hands or a spatula, gently press the dough evenly across the bottom of the pan.
Bake for 30 to 35 minutes. They're ready when the edges are beautifully golden, and the top feels set but still a little tender to the touch. It shouldn't feel wet at all.
Let the blondies cool completely in the pan. This step is super important for them to firm up perfectly before glazing.
For the Strawberry Glaze:
While the blondies cool, make your glaze! In a blender or food processor, blend the coarsely chopped strawberries and lemon juice until completely smooth.
Pour the strawberry mixture into a small bowl. Gradually whisk in the powdered keto sweetener until you get a smooth, drizzling consistency. If it's too thin, add a tiny bit more sweetener.
Once your blondies are completely cool, gently spread the luscious strawberry glaze evenly over the top.
Pop the pan into the refrigerator for at least 30 minutes. This helps the glaze set beautifully and makes the blondies much easier to slice.
Using the parchment paper overhang, lift the entire blondie slab from the pan. Cut into delightful squares and get ready to enjoy your healthy, sweet treat!
