Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
2 1/2 cups all-purpose flour
1 teaspoon baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
3/4 cup vegan butter, softened
1 cup granulated sugar
1/4 cup unsweetened plant-based milk
2 teaspoons vanilla extract
For the frosting:
1/2 cup vegan butter, softened
2 cups powdered sugar
2 tablespoons plant-based milk
1 teaspoon vanilla extract
Directions
Start by preheating your oven to 180°C (350°F). Lightly grease or line a 9×13-inch baking pan with parchment paper to prevent sticking.
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set this dry mixture aside.
In a large mixing bowl, cream the softened vegan butter and sugar together until light and fluffy. This step helps create a soft texture, so mix for at least 2–3 minutes.
Add the plant-based milk and vanilla extract to the butter mixture, and mix until fully combined.
Gradually add the dry ingredients into the wet ingredients, mixing just until a soft dough forms. Avoid overmixing to keep the bars tender.
Press the dough evenly into the prepared baking pan, smoothing out the top with a spatula.
Bake for 18–22 minutes, or until the edges are lightly golden and the center is set. Remove from the oven and allow the bars to cool completely in the pan.
While the bars cool, prepare the frosting. Beat the vegan butter until smooth, then gradually add powdered sugar. Add plant-based milk and vanilla extract, mixing until creamy and spreadable.
Once the bars are fully cooled, spread the frosting evenly over the top. Slice into squares or rectangles and serve.

Variations
You can easily switch up these cookie bars to suit your taste. Add lemon zest or almond extract for a flavor twist. For a festive version, mix in colorful sprinkles or top with dyed frosting. Chocolate lovers can fold dairy-free chocolate chips into the batter. You can also add a thin layer of jam under the frosting for a fruity touch.
For a slightly healthier option, substitute part of the all-purpose flour with whole wheat flour, though this may slightly change the texture.
Storage/Reheating
Store the cookie bars in an airtight container at room temperature for up to 3 days. If you prefer them chilled, you can refrigerate them for up to 5 days, which also helps the frosting set more firmly.
To freeze, place the bars in a single layer or separate layers with parchment paper in an airtight container. They can be frozen for up to 2 months. Thaw at room temperature before serving.
These bars do not require reheating, but if you prefer a softer texture, you can let them sit at room temperature for a few minutes before eating.
