Ingredients for oat banana blueberry muffins

If you’re an avid baker, you probably already have most of the following ingredients handy for these yummy nutty banana blueberry oatmeal muffins. If you are curious about potential swaps for making these walnut banana blueberry oatmeal muffins, be sure to check out the FAQs section below.

Some things that you may not already have stocked up for these nutty blueberry oatmeal muffins are the ingredients that bring this recipe to life with flavor and healthy qualities. Some of the ingredients are even great for helping to keep your blood sugar balanced, making these blueberry banana muffins a yummy option even if you have diabetes.

• Ripe bananas: Ripeness ensures your bananas are sweeter, which makes these oatmeal muffins taste like more of a dessert than just a breakfast treat. Opt for ripe, but not too ripe, to keep the glycemic index a bit lower and to seal in the high antioxidant content of your bananas. You may be thinking, “how can I add banana to a muffin mix?” – the answer is simple. You mash them! Bananas help make your muffins moist and cake-like.
• Oat flour: Whether you purchase premade oat flour or blend up some rolled oats yourself, oat flour is a great option for adding some gluten free whole grain goodness to your baked goodies. Oats are also one of my favorite blood sugar reducing foods and they have tons of health benefits.
• Blueberries: Berries are another one of my dietitian recommended foods that help with reducing blood sugar. Adding some berries into these muffins gives you a nice dose of vitamins, minerals, antioxidants, and a bit of fiber. These can be either fresh or frozen blueberries, whichever is more convenient for you.
• (Optional) Walnuts: Adding walnuts to this muffin recipe adds a nice crunch for texture, a delicious nutty flavor, along with some amazing health benefits. Nuts help reduce the body’s glycemic response to carb-rich meals, making them a perfect component to add to muffins to help keep your blood sugar balanced. Be sure to opt for raw or dry roasted walnuts to guarantee there is no extra fat or sugar added.

In addition, make sure you have the following standard baking ingredients needed to prepare these oat banana blueberry muffins:

• Butter
• Egg

FAQs

Do I need to use oat flour, or can I substitute it for another flour?

In general, substituting the oat flour is not recommended because most of the time it wouldn’t be a simple 1-to-1 substitution ratio. The oats also give a characteristic flavor to these oat banana blueberry muffins, so I recommend sticking to the recipe if possible!

If you don’t have oat flour handy, remember that you can make your own by simply blending up some rolled oats! Any leftover oat flour that you prepare can be stored for future use in an airtight container.

If you must try using different gluten-free flour, whole wheat flour, or all-purpose flour, then be sure to research for the proper substitution ratio in advance.

Can I swap blueberries with another type of berry?

Absolutely! These oatmeal muffins can easily be made with raspberries, blackberries, or chopped strawberries. This ingredient can be swapped out as you please with another berry in equal quantities. If you give a different berry a go, let me know what you think!

Can I make these with a different kind of nut?

The walnuts are optional in this recipe, and you can feel free to experiment using a different kind of nut as well. This banana blueberry muffin recipe would also taste amazing with almonds, peanuts, cashews, or even pecans. If you try making these muffins with a different type of nut, please let me know how it goes!

Can I use a different sweetener instead of sugar?

If you are concerned about the sugar content of these oat banana blueberry muffins, there are a few options. The first being that you can reduce the sugar content by just using a little bit less than what the recipe calls for. Reducing the sugar shouldn’t impact the final result too much since there is plenty of sweetness coming through from the bananas.

Another option is to replace the sugar in this oat banana and blueberry muffin recipe for a sugar-alternative like xylitol or erythritol in a 1-to-1 ratio. Since these sugar-free alternatives do not spike blood sugar levels, they can be a good option for people with diabetes who want to keep their added sugar intake low.

However, one thing to note is that it is important to be mindful while using these options because for some people they can cause digestive issues when consumed in excess. So, if it is your first time trying out these sugar substitutes, ease into it to see how it affects you.

One last thing to note is that this recipe contains other ingredients that help keep your blood sugar balanced, including oats, blueberries, and walnuts. You are also getting some fiber, fat, and protein to balance out the carb and sugar content. If you have diabetes, you can enjoy this treat while keeping track of your carbs for the day.
