Preheat your oven to 350°F (175°C). This is crucial for achieving that perfect chewy texture.
Line a 9x9 inch baking pan with parchment paper, leaving some overhang on the sides for easy removal later. This also helps prevent sticking.
In a mixing bowl, whisk together the almond flour, baking soda, and sea salt until well combined. Set aside.
In another bowl, melt the unsalted butter and then add the granulated sugar. Using a whisk, mix them together until the mixture is light and fluffy.
Crack in the large egg and pour in the vanilla extract. Continue to whisk until everything is well incorporated.
Gradually add the dry mixture to the wet mixture, stirring until just combined. Be careful not to overmix, as this can affect the texture.
Gently fold in the semi-sweet chocolate chips, ensuring they are evenly distributed throughout the batter.
Pour the batter into the prepared baking pan and spread it out evenly. Bake in the preheated oven for 20-25 minutes, or until the edges are golden brown and a toothpick inserted in the center comes out with a few moist crumbs.
Allow the blondies to cool in the pan for about 10 minutes before lifting them out using the parchment paper. Let them cool completely on a wire rack before slicing into squares. Enjoy your Chewy Gooey Almond Flour Blondies!
