Why I love Sourdough Coconut Banana Bread Recipe
Sourdough Coconut Banana Bread is one of the most deliciously amazing loaves you’ll ever taste! If you’re a fan of coconut then this loaf is just what you need…it’s a delicate loaf that simply melts in your mouth. Oh my goodness.
If you’re like me, I used to only be familiar with sour dough bread loaves which are very good but have a strong, sharp flavor to it. These recipes using sour dough start that I have been sharing with you are much more mild. The sour dough starter just adds a little bit of ‘tang’ to it and let me tell you it’s a tang you want to experience! Seriously.
It’s a whole new flavor accent that I completely adore! This recipe alone is completely worth getting your sour dough start going 🙂

Ingredients in Sourdough Coconut Banana Bread Recipe
- Coconut Oil- Contains healthy fatty acids. May boost heart health. May encourage fat burning. May have antimicrobial effects. May reduce hunger. May reduce seizures. May raise HDL (good) cholesterol. May protect your skin, hair, and teeth.
- Granulated Sugar- Granulated sugar is also sometimes known as white sugar, or “regular” sugar. Granulated sugar has had all of the naturally present molasses refined out of it. The fine crystals in granulated sugar don’t cake together, which makes it perfect for measuring, sprinkling onto food and dissolving into drinks.
- Brown sugar- Brown sugars are white granulated sugar that has had cane molasses added to it and it adds moisture so makes it chewier than white sugar. The two types of brown sugar, light and dark, refer to the amount of molasses that is present. Light brown sugar is used more often in baking, while dark brown sugar, with a bolder molasses flavor, is delicious used as a rub for steaks.
- Healthy Benefits of Eggs:
Eggs are among the most nutritious foods on the planet.
A whole egg contains all the nutrients required to turn a single cell into a baby chicken.
A single large boiled egg contains:
Vitamin A: 6% of the RDA
Folate: 5% of the RDA
Vitamin B5: 7% of the RDA
Vitamin B12: 9% of the RDA
Vitamin B2: 15% of the RDA
Phosphorus: 9% of the RDA
Selenium: 22% of the RDA
Eggs also contain decent amounts of vitamin D, vitamin E, vitamin K, vitamin B6, calcium and zinc
This comes with 77 calories, 6 grams of protein and 5 grams of healthy fats.
Eggs also contain various trace nutrients that are important for health.
In fact, eggs are pretty much the perfect food. They contain a little bit of almost every nutrient you need.
If you can get your hands on pastured or omega-3 enriched eggs, these are even better. They contain higher amounts of omega-3 fat and are much higher in vitamin A and E. - Bananas- are also rich in potassium, fiber and natural sugars. The vitamin C, potassium and other vitamins and minerals bananas contain help to maintain overall good health. Because the fruit’s sugar content is balanced with fiber, it helps maintain a healthy blood glucose level.
- All-Purpose & Cake Flours- We are using two varieties of flour: all-purpose flour and cake flour. Combining these two flour produces the perfectly flaky crumb which is what exactly the “secret” that everyone will rave about! Does it really make a difference you might be wondering? Cake flour is a finely milled, delicate flour with a low protein content; it’s usually bleached. When used in baked goods, it results in a super-tender texture with a fine crumb, and a good rise. The primary difference between cake flour and all-purpose (AP) flour is the protein content which becomes gluten. Cake flour is self-rising and it replaces the need for baking powder in this recipe.
- Sea Salt- is mostly composed of sodium chloride, a compound that helps regulate fluid balance and blood pressure in the body. Since it’s minimally processed, it contains some minerals, including potassium, iron, and calcium.
- Coconut flakes: provide healthy fats, dietary fiber, and essential minerals that support energy, digestion, and overall wellness.
- Butter- Butter is rich in nutrients and beneficial compounds like butyrate and conjugated linoleic acid. High-fat dairy products like butter have been linked to a reduced risk of obesity, diabetes, and heart problems. Still, butter is high in calories and saturated fat and should be enjoyed in moderation.
