In a large bowl, mix together almond butter, applesauce, maple syrup and vanilla until smooth.
Next add zucchini, cocoa powder, ground oats, baking soda, espresso powder and salt and mix ingredients together until well combined.
Pour batter into the prepared baking pan. With a toothpick swirl in the 2 tbsp of almond butter into the batter.
Bake 25-30 minutes until a toothpick can be inserted into middle of the brownies and comes out clean. Remove from the oven and allow to cool in the pan 30 minutes prior to slicing into 12 brownies and devouring!
Notes
Allow the brownies to cool completely before slicing them with a warm knife.
Squeeze the excess moisture from the zucchini to avoid watery brownies.
Let the brownies set overnight to develop a more fudgy texture.
