FAQs
1. Can I use a different sweetener instead of coconut sugar?
Yes, you can substitute coconut sugar with maple syrup, honey, or any sweetener of your choice. Just keep in mind that liquid sweeteners may slightly alter the texture of the brownies.
2. Can I make these banana brownies vegan?
Absolutely! To make these brownies vegan, swap the Greek yogurt for a plant-based yogurt (such as almond or coconut yogurt), and choose dairy-free dark chocolate chips.
3. Can I use regular flour instead of oat flour?
Yes, you can substitute oat flour with all-purpose flour. However, if you want to keep these brownies gluten-free, make sure to use a certified gluten-free oat flour.
4. What if I don’t have walnuts?
You can either omit the walnuts or replace them with other nuts like almonds, pecans, or hazelnuts. You could also use seeds, such as chia or sunflower seeds, for an added crunch.
5. How do I make these brownies more fudgy?
To achieve a more fudgy texture, bake the brownies for less time, around 25 minutes, or until the top looks set but still soft to the touch.
6. Can I freeze these banana brownies?
Yes! Once the brownies have cooled completely, wrap them tightly in plastic wrap or store them in an airtight container, and freeze for up to 3 months. To thaw, leave them at room temperature or heat them in the microwave.
7. Can I add other mix-ins like dried fruit or nuts?
Definitely! You can customize these brownies by adding in dried fruit like raisins or cranberries, or nuts like pecans or almonds. Get creative with your add-ins!
8. Can I use almond flour instead of oat flour?
Yes, you can use almond flour instead of oat flour. However, almond flour tends to be more dense, so you might need to adjust the amount of liquid ingredients slightly.
9. Are these brownies suitable for people with nut allergies?
These brownies can be made nut-free by omitting the walnuts and using a nut-free yogurt. Just make sure your chocolate chips don’t contain any traces of nuts.
10. How do I know when the brownies are done baking?
The brownies are done when the top looks set, but they still feel soft to the touch. You can also insert a toothpick – it should come out with a few moist crumbs, not wet batter.
