Protein Pumpkin Bread

Pumpkin is one of my favorite vegetables to eat. But did you know botanists say that Pumpkins are fruits because of the seed-bearing structure of flowering plants? Although they are less sweet and more on the savory side, the culinary industry classed them as vegetables.

As I was saying, pumpkin is my favorite veggie ever, has very little calories and has a lot of flavour. And when mix with the correct spices it is heaven. It is versatile, can be used in sweet and savory dishes, great! isn’t it?


Well, I have tones of protein powder to use up, so…. Hahaha, so I like to include a bit extra of protein in my diet to maintain and increase muscle mass, while I work out. So, what better way to do it than this.

For this recipe, I used my trustee, Whey Isolate Protein that is sugar-free, gluten-free, and lactose-free from BiotechUsa. But you can use any other of your preference. Just bear in mind you might need to change a bit the liquids in the recipe depends on how absorbent it is your choice.

For example, I use Beef Isolate Protein Powder by Bulk Powders in my Double Chocolate Banana Bread which gives me a much moister crumb. Although, if you want to omit the protein powder, just sub with more flour.

Another plus for using protein powder in this Pumpkin Bread is that will add strength to the loaf, making it less dense and cakey and more bread-like kind of texture, but yet moist.

For my Double Chocolate Protein Banana Bread, I used Beef Isolate Protein, it is delicious and so moist, you should look at the recipe.


In this recipe, I am combining erythritol and stevia blend with coconut sugar, to add an extra sweetness but without being overpowering. This is supposed to be a bread loaf, not a cake. Bear in mind how sweet is your protein powder is, which will determine the amount of sweeteners you will use.

Gluten Free Pumpkin Bread

I still want to be able to lather some of my homemade blackberry jam, or Nutella without gagging because it is too sweet altogether. Well, that is just me. But by all means, if you would like to use all coconut sugar or increase the amounts, feel free to do it so.

I did also, add some molasses more for flavoring and coloring rather than for sweetness. I think sometimes adding too much of it, can mask the flavor of the spices, and any other add-in to your baked goods.


In this bread, I decided to include some nuts and dried fruit for crunchiness and a bit of a bite to it. In my opinion walnuts and pecans called for fall and winter baking along with the raisins and sultanas. But you can definitely add your favorite nut or dried fruit. Like pistachios and my sugar-free dried cranberries, this will be my next combination. Also, you could add chocolate chips, feel free to experiment in the kitchen, that is the beauty of cooking.


For the gluten-free flour blend, I choose to use a blend of Buckwheat, Brown rice and Millet Flour. Because of the ability to absorb liquids, and I am using a high amount in this recipe. Between the pumpkin puree, molasses, sugar-free syrup, eggs, etc.

You can swap the flours for and self-raising gluten-free flour if you’d like just leave the xanthan gum out. But you still will need the baking powder and baking soda for raising along with the vinegar.

In the case that you don’t have or don’t want to use sourdough discard, substitute it for 65g of the flour of your choice and 65g of water.


I don’t know if you already know but I love sourdough bread, the tanginess, also is healthy for your gut. But not just that is the reason I made this recipe with sourdough discard; I had a few jars to go through. One of my to-go in using my sourdough discard is my Pumpkin Waffles and now this Gluten-free Protein Pumpkin Bread.

In my opinion, I think by adding sourdough starter whether is discard or active to this classic fall/autumn recipe gives it a less dense and lighter crumb and fascinating, delicious tangy flavor.

However, if you don’t have or don’t want to use your sourdough starter you can substitute by adding 65g sorghum/buckwheat flour and 65g of water.


Sugar Free Pumpkin Bread

If you can get your hands on pumpkin spice in the shop, there is no problem. I always prefer to make my own for a fresher spice blend. You only will need a mortar and pestle or a coffee/spice blender. And for the amounts you can check my Pumpkin Waffles Recipe. I can assure you always taste better when you do everything from scratch. But always you can use store-bought spices.


Protein: This recipe gets its protein from a high-quality Isolate Whey Protein powder and eggs. Traditionally, Pumpkin Bread recipes are packed with sugar and fat, and refined carbs. So, to make this recipe a healthy version of its original I swap some of the flour with protein powder. Resulting in a much sturdier yet moist loaf that will help you building and maintaining muscle mass.

Sourdough Pumpkin Bread

Low Fat: The fat content in this recipe comes from a great source like egg yolk and the olive oil (which you cannot taste in the final loaf). Although the amount is quite low, the bread is still moist and not dry, like usually high protein bakes are. Bear in mind that in anabolic diets the fats are at their minimum, by increasing the carbs and proteins resulting in a dryer crumb. However, in this recipe, the taste and texture won’t be compromised.

Fiber: Pumpkins are high in fiber and rich in antioxidants and vitamin A. Also, Psyllium Husk is a soluble fiber, helping your digestion and filling satiate for longer. Also, is a prebiotic, which means it is food for the healthy bacteria in your gut. Another reason, for me including psyllium husk in this Protein Pumpkin Bread is because this is a gluten-free recipe, meaning there is no gluten to give structure to the loaf. Then, psyllium husk in combination with xanthan gum will act as a binder to mimic gluten, to help the bread from being crumbly and a mess.

Cinnamon: Among all the spices used in this recipe Cinnamon is one of the healthiest spices ever. It has the power of helping lowering blood sugar levels and burning more calories throughout the day.


Oven: Make sure your oven is preheated at the right temperature, before baking the bread. This will determine the final result of the loaf, cold ovens undercook bread, too hot ovens will burn the top of the loaf, also it can burst it because the air will try to find somewhere to scape.

Undercook: when you cut into your bread there are some parts that look gooey or undercook, which means your batter was too liquid. This will depend on the type of flour and protein powder you used. Try to bake it longer next time and always use a skewer or knife to check is done. Also do not cut while still warm, leave it cool down completely.

Overmixing: If your crumb has large holes tunneling) means that you over-mixed the batter. Quick bread like this Pumpkin Pie Protein Loaf will have a more even crumb. So, you can beat the wet ingredients but when combining with the dry ingredients do it, as little mixing as possible. Fold ingredients until no dry bits, we don’t want to add air into the batter. The leavening agents will do the lift.


The best way to store this Pumpkin Protein Loaf is in the fridge if you are going to eat it within 5 days. It can be kept at room temperature (21 C or below) for 2 to 3 days. But because it has a great content of pumpkin, and to avoid mildew I rather store it in the fridge or in the freezer.

There are many ways to do it, you can slice it all through and place it in a zip lock freezer bag like the Ikea ones (this is my preferred method). Or separate the slices with greaseproof or parchment paper then put them in a freezer bag or airtight container.

When you decide to eat it just pop it in the toaster in defrost mode and then toast it if you want. I love my one toasted with butter or some of my Cranberry Sauce, or my Homemade Nutella, yummy!!!


Brown Rice and Buckwheat Flour are heavy flours so I suggest if you swap them try for one to another for the full amount or you could use XYZ. Although, I haven’t tried making this loaf with those flours.

Millet Flour is a medium flour so you could in theory substitute it for XYZ but I haven’t tried those either in this recipe.

Psyllium Husk, you could use powder or whole, but I’m afraid there is no substitution for this ingredient. Although, there are people who will say that chia seeds or flaxseed but to be quite honest, I do not like them as a substitute but as add-ins to add more fiber. But I find out that make baked goods a bit mushy and dense.

Pumpkin Puree, you can use canned pumpkin puree or make your own. The latter is my preferred way. It’s easy just cut open in half the pumpkin remove the seeds and place it on a baking tray with the skin facing up. Bake the pumpkin for 45min at a 180 C fan-assisted or 200 C conventional oven.

Eggs, in this recipe the eggs work as the glue to hold everything together along with the psyllium husk and xanthan gum. You could use egg replacer, although, I have not tried this.

Nuts and dried fruit, you can use any kind you like or prefer, or simply omit them if you don’t have any, and add chocolate chips.

Vinegar, I highly suggest do not leave out this ingredient, is crucial for leavening this scrumptious Protein Pumpkin Bread along with the baking soda and baking powder.

Oil, if you want to reduce the fat content in this bread you can swap the oil for unsweetened apple sauce.

  • In a medium-big bowl mix all dry ingredients but the dried fruits and nuts. Set aside.
  • Now mix all wet ingredients, pumpkin, egg, egg yolk, oil, sugar-free syrup, molasses, vanilla extract, vinegar, rum, but the sourdough starter, the erythritol, and coconut sugar. Whisk slowly we don’t want to incorporate air in the mixture, or over mix.

When the 50min is up check if the bread is fully cooked by inserting a skewer or knife, it comes out clean it is done. If not, bake for another 5 to 10min and check again.
  • Remove the bread from the oven and cool it in the pan on a wire rack for 10 minutes. Then turn it out of the loaf pan over the wire rack and allow it to cool completely before slicing.
