Ingredient Notes
Fresh Lemon: Grab two lemons for this recipe. You will need the zest of both and the juice of at least one. You may need the juice of both if your lemons aren't super juicy.
Non-Dairy Butter: I love Country Crock Plant Butter Sticks! They taste great and are easy to find.
Non-Dairy Milk: I used oat milk, but almond milk or soy milk will also work.
Powdered Sugar: Powdered sugar is crucial for making the lemon glaze for the cookie bars, so make sure you have it!
Instructions
Step 1. In the bowl of a stand mixer fitted with the paddle attachment, cream non-dairy butter, sugar, and lemon zest until well combined and fluffy.
Step 2. Then, add non-dairy milk, lemon juice, and vanilla and mix on low until combined.
Step 3. Next, add flour, baking powder and salt and mix on low until the dough forms.
Step 4. Then, scoop the dough into a prepared 8-inch by 8-inch square baking pan. Use a mini offset spatula or lightly oiled hands to spread the dough out evenly.
Then, bake in a 350°F oven for 34-38 minutes or until the edges are golden brown.
Step 5. To make the lemon glaze, combine powdered sugar, non-dairy milk, lemon juice, and lemon zest in a medium bowl.
Whisk until completely smooth.
Step 6. Pour the glaze onto the lemon cookie bars and spread it out with an offset spatula or a butter knife.
Allow the glaze to set for at least an hour before slicing and serving.
Recipe FAQs
Place the bars in an airtight container and store at room temperature for up to 4 days.
Or freeze for up to a month.
Lemon zest is where all the lemon flavor is. So, plenty of lemon zest adds bold lemon flavor.
Lemon glaze is a combination of powdered sugar, lemon juice, non-dairy milk or water, and lemon zest. It is a tangy and sweet addition to bars, loaf cakes, and cookies!
Expert Recipe Tips
Be sure to allow the glaze time to set. If you slice the bars too quickly, the glaze will run!
I really love a mini offset spatula to spread the cookie dough out and to spread the glaze!
