Pumpkin Apple Cake: Low in histamine, high in fiber, and good for your gut

At first glance, cake and gut health don’t seem to go together. That’s exactly what I wanted to achieve with this recipe.
In my kitchen, fall always means pumpkin. Since I was craving something sweet and the taste of apples, I came up with this moist pumpkin-apple cake. It’s vegan, gluten-free, high in fiber, low in histamine, and sugar-free.
Why Fiber Is So Important for Your Gut
Fiber serves as food for your gut bacteria. They convert it into short-chain fatty acids, which in turn keep your gut lining healthy. This means that the more varied your fiber intake is, the healthier your microbiome will be.
The recommended daily intake is about 30 grams of fiber. However, most people don’t even reach 20 grams a day. Since you probably value a balanced diet, this might be a gentle reminder to keep making sure you’re getting enough fiber. Especially when baking, it’s often just white flour and refined sugar that end up in the bowl.
That’s why I love this high-fiber cake recipe so much. It doesn’t feel like a sacrifice either, because it’s so delicious and moist.

Why This Cake Is Low in Histamine
People who are sensitive to histamine often have a hard time baking. Many popular ingredients, such as cocoa, bananas, citrus fruits, or certain nuts, aren’t well tolerated by everyone with this sensitivity.
This vegan pumpkin apple cake doesn’t contain any of these ingredients. It’s made with pumpkin, apples, rice flour, buckwheat, oats, coconut oil, and rice milk. Many people with histamine intolerance often tolerate these ingredients better. That’s why this cake can be a good alternative for some.
There are three things you should keep in mind, though:
Cinnamon
Most people tolerate small amounts well. If you’re very sensitive to it, you can reduce the amount or use a little vanilla instead.
Freshness matters
The cake tastes best when fresh. However, you can also freeze it in individual portions and thaw it as needed.
Everyone reacts differently
Histamine intolerance varies greatly from person to person. That’s why it’s a good idea to test new foods based on your personal tolerance.
The result is an autumnal cake that can be a well-tolerated option for many people with histamine intolerance without – sacrificing flavor or enjoyment. 🍂🎃🍎
What Makes This Cake So High in Fiber
Almost every ingredient plays a part here:
- Buckwheat flour contains significantly more fiber than wheat flour and, despite its name, is gluten-free.
- Oatmeal provides beta-glucan, a soluble fiber that keeps you feeling full for a long time.
- Psyllium husks help bind the batter and also give your digestion a real boost.
- Pumpkin and apple make the cake moist, and the apple adds pectin. A fiber that’s a favorite food source for many gut bacteria.
In the end, each slice contains about 7 grams of fiber. That means you’ve covered almost a quarter of your daily fiber needs. All from just one slice of cake. 🙂

Pumpkin Apple Cake, Gluten-Free, Vegan, Sugar-Free, Low in Histamine
Ingredients
- 300 g Hokkaido squash, trimmed and diced
- 1 large apple, about 200 g peeled, cored, and diced
- 60 g rice flour
- 60 g buckwheat flour
- 50 g finely ground gluten-free rolled oats
- 1 tsp ground psyllium husks
- 1 tsp baking powder
- 1 tsp cinnamon
- 100 g erythritol
- 150 ml rice milk
Instructions
- Steam the pumpkin in a little water until tender, drain well, and let cool briefly.
- Blend the pumpkin with rice milk, cinnamon, salt, and erythritol until smooth and creamy.
- Preheat the oven to 180 degrees (top and bottom heat) and grease the baking pan.
- Finely grind the rolled oats or use pre-ground oats, then mix them with rice flour, buckwheat flour, psyllium husks, and baking powder.
- Add the pumpkin cream to the flour mixture, stir in the coconut oil, and mix well. Fold in the diced apple.
- Pour the batter into the pan and smooth the top.
- Sprinkle the surface evenly with a little erythritol; this will create a delicate sugar crust during baking.
- Bake for about 40-50 minutes, then test for doneness with a toothpick. Let cool completely.

My Tips for Success
The coconut oil should be liquid, but not hot. And the pumpkin puree should be only lukewarm. Otherwise, the oil will solidify into small flakes.
Line the pan with parchment paper as well. Gluten-free batters tend to stick, so this ensures the cake comes out of the pan easily.
It’s best to let it cool completely. It will firm up overnight and taste even better. I know it’s hard to wait when the whole house smells so wonderful with the aroma of freshly baked cake.
Frequently Asked Questions
Can I use the Hokkaido pumpkin with the skin on?
Yes. The skin softens during steaming and adds extra fiber.
Is this cake suitable for a low-histamine diet?
Many of the ingredients used are often well tolerated by people with histamine intolerance. If you’re very sensitive, it’s best to reduce the amount of cinnamon and eat the cake fresh.
Which rice drink should I use?
Ideally, one without additives – just rice, water, and possibly salt. Many people with histamine intolerance often tolerate rice drinks without additives better.
Can I substitute the erythritol?
Yes, for example, with coconut blossom sugar. However, the cake will then no longer be sugar-free.
Why psyllium husks?
Gluten-free dough lacks the gluten needed to hold everything together. Psyllium husks do this perfectly. They prevent the cake from becoming crumbly.
How long does the cake last?
Well-covered in the refrigerator, it will last 2 to 3 days. If you’re watching your histamine intake, it’s best to freeze it in individual portions and thaw it when you’re ready to eat it.
Have you tried the pumpkin-apple cake?
Then I’m sure you’ll agree that healthy baking recipes don’t have to taste like a compromise. This pumpkin-apple cake is wonderfully moist, has a pleasant cinnamon flavor, and gets a slightly crispy top thanks to the delicate erythritol crust. At the same time, it’s high in fiber, vegan, and a well-tolerated alternative for many people with histamine intolerance.
