When it comes to baking in the fall., there’s nothing quite as satisfying as the aroma of fresh pumpkin banana muffins filling your kitchen.

Sourdough Discard Pumpkin Banana Muffins

Sourdough is a beloved ingredient in bread-making and offers numerous health benefits.

The fermentation process used to create sourdough bread enhances its nutritional profile. Sourdough is easier to digest than traditional yeast bread. In sourdough, lactic acid bacteria break down gluten, fructans, and phytic acid. This can be particularly beneficial for individuals with gluten or FODMAP sensitivities.

Muffins are not usually long-fermented, but they can be! I don’t long ferment my muffins, but many readers have told me they have successfully fermented the batter overnight in the fridge for easier digestion. You can try fermenting the batter overnight in the fridge before preheating your oven and filling your muffin tin with batter.

My Pumpkin Banana Muffin Recipe

Pumpkin is an underrated superfood—pumpkin, or any winter squash, is a nutritional powerhouse. Rich in bioavailable vitamins A and C, pumpkin contributes to a robust immune system, promotes healthy skin, and supports eye health.

Pumpkins have a lot of dietary fiber too, which aids in digestion and helps regulate blood sugar levels. Pumpkin contains antioxidants that protect against cellular damage, reducing the risk of chronic diseases such as heart disease and certain cancers.

Including roasted pumpkin in your muffins makes for a fluffier texture and muffins that are full of vitamins and minerals.

Never Over-Mix Muffins

When making muffins, one crucial tip is to avoid overmixing the batter. Overmixing can result in dense muffins rather than light and fluffy ones. The reason behind this lies in the formation of gluten.

Gluten, a protein present in flour, gives structure to baked goods. However, excessive mixing develops gluten strands, leading to a denser texture. To prevent this, gently mix the dry and wet ingredients until just combined, ensuring there are still some lumps and streaks of flour in the batter.

This technique allows the muffins to rise correctly, resulting in a tender crumb and a delightful eating experience.

My other muffin baking tip is always to use a thin metal aluminum muffin tin with paper liners. A metal muffin tin works way better than a silicone muffin pan.

How to roast a pumpkin: cut and clean a pumpkin, rub the inside with a little oil, place it open-side down on a sheet pan, and roast at 425° F for about 20 minutes. Once it is completely cool, you can scoop the pumpkin out of the skin and use it in the recipe.

I really enjoyed the checklist for your recipe. I am currently sipping a cup of coffee with these delicious muffins now! The sweetness is very gentle I appreciate the crumb on these. I used up some old fridge discard for these. A couple of tweaks I made were using EVOO for butter, 1 cup whole wheat, and 1 cup white flour. I added twice the cinnamon. Canned pumpkin as well. I passed on the crumble and added pumpkin and poppy seeds on top instead. I would love to try it with a vegan egg and see how it compares.
