Peanut Butter Zucchini Bread

If there’s one thing that I love about summer it’s the warm weather. Of course, where we live, weather is always changing. It could be hot and humid in the afternoon and then two hours later it could be pouring rain and drop 15 degrees in temperature. I’m not really one for baking when it’s too hot, but when there’s a cool wind blowing and rain clouds lingering around, it’s the perfect weather for heating your oven and filling your house with the smells of baking bread.

Especially when it’s peanut butter bread.

 Hide your zucchini in this Peanut Butter Zucchini Bread with Brown Sugar Streusel. You’ll never guess this bread has veggies inside!

This amazing Peanut Butter Zucchini Bread is actually based off of our original zucchini bread post, Grandma’s Zucchini Bread. I absolutely love that recipe, but this bread kicks things up a notch with a great peanut butter flavor. I am a firm believer that everything should have a peanut butter version! This bread is so peanut buttery that it hides two cups of zucchini inside. No one will ever know!

To make this quick bread successfully, you’ll need to mix all the dry ingredients in one bowl and mix all the wet ingredients in another. Then add the dry ingredients to the wet and mix just until combined. Why dirty two bowls? It’s so that you don’t over mix the batter.  If you mix it too much, your quick bread will not rise as much when it bakes. Over mixing develops gluten, which makes the bread chewy and form air bubbles or tunnels. This is good with normal homemade bread that you knead and let rise to give it that chewy soft texture, but that’s not what you want for you quick bread.

My Grandpa came over for my thirteenth birthday on Monday, and we had him try some of this bread. He really liked it, but we didn’t tell him what it was until after he ate it. He was shocked to hear that it was zucchini bread. He never would have guessed. So if you want to get some extra veggies into your kids food while they think they’re eating dessert, this is a great way to do it!

Streusel Topping:

  • 1/2 cup brown sugar

  • 3 tablespoons softened butter


  • Mix together the peanut butter, oil, sugar, eggs, vanilla, zucchini and peanut butter chips in a bowl. Set aside. In a separate bowl, mix together the flour, salt, baking soda, and baking powder. Add the wet ingredients to the dry ingredients and mix just until combined.
  • In a small bowl, combine the brown sugar, flour and softened butter. Mix until the streusel is crumbly.
  • Grease and flour two loaf pans. Split the batter between the two pans. Divide the streusel topping between the two loaf pans, sprinkling the streusel on top. Bake at 325 degrees for 1 hour and 5 minutes.

perhaps I missed it – but do you squeeze your grated zucchini? Or just grate and use? Thanks…

I’m a huge peanut butter fan and this bread is amazing!!! I made 1 loaf and 12 cupcakes with this recipe. The cupcakes took about 25 minutes to cook. So yummy! Thanks for the recipe, this will be my new favorite zucchini bread recipe.

Love love love! I initially made this following the directions above, but found it to be too sweet for my liking. The past two times I have made it I have used PB Fit instead of normal peanut butter and oat flour/ coconut sugar instead of regular flour and regular sugar- tastes just as wonderful without being too sweet! (And it’s a bit healthier this way, too). Thanks for the recipe!

This looks and sounds delicious! My boys love a traditional zucchini bread, and by adding some PB and streusel this version sounds over-the-top! I also appreciate that the recipe uses some zucchini, since I have an overload in my garden at the moment! Pinned!

Thanks so much for the info about not over mixing quick breads. I guess an old dog can learn new tricks 🙂
