Zucchini Bread Double Chocolate

This Zucchini Bread with Double Chocolate will make you happy!  

The Doctor is in,  Doctor Jo that is. Today I have baked up a prescription of double chocolate zucchini happiness. This bread makes me happy. It is super chocolatey, and I love chocolate.  It is sooo moist and loaded with chocolate chips. However, I also know that chocolate is used by the body to make serotonin, the happiness neurotransmitter. Even better, I am enjoying my vegetables when I bite into a slice of this zucchini bread. Happiness and vegetables together in the perfect dessert. I’m prescribing a piece today.  

What are the ingredients in this zucchini bread? 

Chocolate, of course, and zucchini. A word about the zucchini. For this recipe, don’t peel or remove any of the extra moisture from the zucchini. Zucchini is 95% water (WOW). 

The zucchini releases most of that water into the bread.  So don’t dismay if the batter is thick and dry looking before you add the zucchini. The zucchini water thins the batter to the perfect consistency. 

I’ve also replaced the white sugar with maple syrup.  The hint of maple goes well with the chocolate, and it is better for you than refined white sugar.  

Are you wondering what the espresso powder is doing in this recipe? Wonder no more. Espresso or coffee enhances and intensifies the flavor of chocolate. It only takes a tiny amount.   Also, the small amount won’t give your zucchini bread a mocha flavor. All you will taste is the deep, dark, decadent chocolate. I’m so happy!!!

How Do I Make and Bake Zucchini Bread with Double Chocolate?

This is a 5 step recipe:

  1. Mix the liquid ingredients together  in a bowl.
  2. Mix the dry ingredients together and add to the liquid ingredients.
  3. Grate the zucchini and add the zucchini and chocolate chips to the rest of the ingredients in the mixing bowl.  Mix all together. Don’t overmix or the center of your loaf will sink during baking. 
  4. Make a parchment sling for your baking pan. (My secret to guarantee a perfect looking loaf every time). Fill the baking pan and bake the zucchini Bread for 55 to 60 minutes or until the center is set and a toothpick inserted into the center comes out clean. 
  5. Let the bread cool for 30 minutes, then remove it from the pan using the parchment sling to lift it out.  No sticking to the pan guaranteed. Slice and enjoy.  I’m off to get me a slice.  See you on the next blog with a happy chocolate-induced grin.

How Do I Make a Parchment Sling?

A parchment sling (click here for parchment paper)is the best way to keep your beautiful loaf of zucchini, or any other batter type bread from sticking to the pan it is baked in.  Here is how to make one:

  1. Cut a piece of parchment long enough to cover the two long sides and bottom of the pan with 1 inch extra on each end.  
  2. Spray the baking pan with nonstick baking spray and stick the parchment into the baking pan.  Leave 1 inch sticking up over the top of the pan.  This will act as a handle when it is time to remove the baked loaf from the pan. 
  3. Spray the parchment with more spray before filling with the bread batter and then add the batter to the pan.  
  4. For this recipe, the batter should only half fill the pan before baking. 
  5. Once the loaf is baked, let it cool for about 30 minutes,  loosen the ends that aren’t covered with parchment, and simply lift your loaf out of the pan using the ends of the parchment as handles.

      So glad you are enjoying this bread. It freezes well and will be delicious if you toast it a bit and enjoy it with a glass of milk on a snowy winter evening.
