👩🍳 How to Make Flourless Zucchini Bars
Step 1: Prep the Pan and Oven
Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper or lightly grease it with coconut oil or nonstick spray.
Step 2: Prepare the Zucchini
Grate zucchini using a fine grater. Place in a clean kitchen towel and squeeze out excess moisture—this keeps the bars from getting soggy.
Step 3: Mix Wet Ingredients
In a medium mixing bowl, stir together:
-
Almond butter
-
Eggs
-
Mashed banana (or applesauce)
-
Honey or maple syrup
-
Vanilla extract
Stir until smooth and well combined.
Step 4: Add Zucchini and Dry Ingredients
Mix in the grated, squeezed zucchini. Then fold in:
-
Oats
-
Cinnamon
-
Baking soda
-
Salt
Add any optional mix-ins at this point, like chocolate chips or seeds.
Step 5: Bake
Spread the batter evenly in the prepared pan. Bake for 25–28 minutes, or until the top is golden and a toothpick inserted into the center comes out mostly clean.
Let cool in the pan for 10–15 minutes, then transfer to a wire rack to cool completely before slicing.
