Gathering Ingredients and Supplies
Now it is time for you to gather all the ingredients and supplies you will need for these delicious low-carb lemon bars. Start by making sure you have all the necessary ingredients on hand. You will need almond flour, powdered erythritol, unsalted butter, eggs, fresh lemon juice, lemon zest, and a pinch of salt. Additionally, you will need a mixing bowl, a whisk, a spatula, a square baking dish, and parchment paper. Make sure to check your pantry and fridge to ensure you have everything before starting. If any items are missing, make a list and head to the grocery store. Having everything ready will make the process smooth and enjoyable.
Preparing the Crust
To create the perfect base for these tangy treats, you’ll need to start by mixing together a few simple ingredients. Begin by combining almond flour, coconut flour, and a pinch of salt in a mixing bowl. In a separate bowl, whisk together melted butter, powdered erythritol, and vanilla extract until well combined. Slowly add the wet ingredients to the dry ingredients, stirring until a crumbly dough forms. Press the dough evenly into the bottom of a greased baking dish, making sure to create a smooth and compact crust. Bake the crust in a preheated oven at 350°F for about 12-15 minutes, or until it turns golden brown. Once done, set aside to cool before adding the lemon filling.
Making the Lemon Filling
First, you’ll want to whisk together some fresh lemon juice, grated lemon zest, and a touch of lemon extract to create a bright and zesty filling that will make your taste buds dance with delight. In a separate bowl, combine almond flour, coconut flour, melted butter, and a low-carb sweetener of your choice to make the crust for your lemon bars. Press the crust mixture evenly into the bottom of a baking dish and bake it in the oven until it becomes golden brown. Once the crust is ready, pour the lemon filling over it, spreading it evenly. Return the baking dish to the oven and bake until the filling is set and slightly firm to the touch. Allow the lemon bars to cool completely before cutting them into squares and serving. The tangy and refreshing flavor of the lemon filling paired with the buttery and nutty crust will surely satisfy your cravings while keeping your carb intake low.
Baking and Cooling the Bars
Once the lemon bars have been baked to a golden brown perfection, the anticipation builds as they cool, allowing the flavors to meld together and create a mouthwatering delight. It is important to let the bars cool completely before cutting into them, as this will ensure that they hold their shape and have the right texture. Place the baking dish on a wire rack and let it sit for at least 1 hour. The bars will continue to firm up as they cool. After they have cooled completely, you can refrigerate them for an additional hour to make them even more firm and easier to cut. Once they are completely cooled, use a sharp knife to cut the bars into squares or rectangles. Serve chilled and enjoy the delicious low-carb lemon bars!
Serving and Storing Tips
For an extra touch of indulgence, serve these mouthwatering treats with a dollop of whipped cream or a sprinkle of powdered sugar. To serve the low-carb lemon bars, carefully cut them into squares or rectangles using a sharp knife. Place each piece on a dessert plate or individual serving dish. The bars can be enjoyed chilled or at room temperature, depending on personal preference. The tangy lemon flavor combined with the buttery crust is a delightful combination that will surely satisfy any sweet tooth. If there are any leftovers, store the bars in an airtight container in the refrigerator for up to 3 days. Before enjoying them again, allow them to come to room temperature or warm them slightly in the microwave for a few seconds.
