Banana Nut Muffins

These Banana Nut Muffins are moist, tender, and tangy from the buttermilk, with warm spices and walnuts for some added texture. I’ve given this old-fashioned 1960’s recipe a modern update making them simple and easy for breakfast, a Sunday brunch table, or a mid-afternoon snack with a cup of coffee.

Dry Ingredients

• Flour: Use all-purpose unbleached flour with 10-12% protein, such as King Arthur or Sir Galahad Artisan Flour (its bulk-purchased name) which has 11.7% protein. Avoid bread flour, as its higher protein content (11-14%), develops more gluten, which results in dense baked goods.
• Baking powder: Baking powder is a leavening agent that contains both cream of tarter for the acid, plus baking soda for the base. It helps your baked goods rise and gives them light, airy texture. Be sure to use a double-acting aluminum-free baking powder, as those that contain aluminum can give your baked goods a bitter aftertaste.
• Cornstarch is made from the starchy center of dried corn kernels used as a thickener in sauces and pie fillings, and in baked goods to create a light, tender crumb.
• salt: Pink salt is a natural, unrefined salt rich in essential minerals and nutrients. Use a fine-ground salt in baked goods for even distribution and balanced flavor.
• cinnamon: Cinnamon comes from dried bark from the tropical Asian cinnamon tree and is available as whole cinnamon sticks or ground. There are two types: Cassia which has a warm, sweet flavor, and Ceylon known as “true cinnamon”, which has an intense spicy bite.
• nutmeg: Nutmeg is a warm spice that comes from the nutmeg tree in the Spice Islands. It is available as whole nutmeg, grated or pre-ground.

Wet Ingredients

• canola oil: Canola oil is perfect for baking as it has a neutral and light flavor. You can swap oil for butter and vice versa as oil provides moisture, and butter provides flavor.
• sugar: Sugar is derived from sugarcane and provides sweetness to baked goods. The most common type being granulated white sugar. Cane sugar is a natural option that is less processed with a slightly courser texture.
• brown sugar: Brown sugar is granulated sugar with molasses added, providing deep flavor and moisture to baked goods. Light brown sugar contains 3.5% molasses and dark brown sugar has 6.5%, giving it more robust flavor.
• buttermilk: Buttermilk is a cultured dairy product that adds a tangy flavor and creates tenderness in baked goods. When purchasing buttermilk, look for simple, natural ingredients such as “cultured milk”.
• eggs: Eggs are important in baking because they lend natural leavening, provide moisture, and add structure through their protein.
• vanilla extract: Vanilla provides hints of caramel and spice, which enhances the depth of flavor in baked goods. Homemade vanilla is best, or use a high-quality, all-natural brand that contains at least 35% alcohol.
• bananas: Bananas are a tropical fruit grown on plants, often mistaken for trees. As they ripen, bananas develop more natural sugars, making them sweeter. It’s best to use them at the brown-speckled stage, as green bananas are unripe. 
• walnuts: Walnuts are the seeds of Juglans trees that are found inside a hard, thick shell that must be cracked open to eat. There are two varieties, the English walnut commonly eaten raw, and the black walnut which has a stronger flavor and often used in savory dishes.

Make your own Ingredients

Buttermilk: Add 1 T. vinegar or lemon juice into a liquid measuring cup and add cream or whole milk until it reaches the 1 c. measure line and let it sit for a few minutes before use.

Vanilla: Purchase Grade B vanilla beans (also called extract-grade), which have less moisture and a more concentrated flavor. Place 8 ounces of bourbon (or vodka) in glass bottle or jar. Split 5-7 vanilla beans down the middle and add to bottle. Let it sit for 3-6 months in a cool, dark place. As you use it, continue to replace the bourbon and add more beans as it keeps for many years.

Dietary Substitutions

For the past 12+ years, I have owned an all-natural specialty bakery converting conventional recipes to gluten free, vegan, wholesome, etc. You can read more about my pro-baking here.

Here are a few basic tips when converting conventional recipes into specialty baked goods.

• Shelf Life: Specialty baked goods tend to dry out faster and have a shorter shelf life than conventional baked goods. Store in an airtight container on counter for 1 – 2 days. For longer storage, freeze up to 6 months. Avoid refrigerating, as it can dry out baked goods.
• Let Batter Rest: Alternate flours can be dense or slightly gritty compared to white flour, so be sure to let the batter rest at least 15 minutes or overnight in the refrigerator before baking. This allows the flour to fully hydrate and produce a lighter, tender crumb.
• Oven Temperature: Alternative flours are delicate and tend to brown faster before the center is cooked through. Reduce oven to 325° and bake “low and slow,” adding a few extra minutes of bake time if needed.

Gluten-Free (no gluten)

• Flour: Swap out the flour with a premium gluten-free flour such as King Arthur Measure for Measure or use a homemade gluten-free flour blend. Be sure the flour blend contains xanthan gum or add 1/4 tsp. to 1/2 tsp. per every 1 cup of flour to the recipe.
• Hydration: Gluten free flours can make baked goods dense. Add 1 tablespoon of additional extra liquid (the same liquid called for in the recipe) to help lighten the texture.
• Fat: Add up to 1 to 2 Tbsp of additional fat, such as butter or oil to the recipe.

Vegan/Dairy Free (no animal products)

• Butter: Use unsalted vegan butter sticks such as Violife for best flavor and texture.
• Dairy: Replace dairy with unsweetened plant based milk such as oat, coconut or almond milk.
• Eggs: Replace each egg by adding 1 tsp. baking soda to the batter, then pour 1 Tbsp. white vinegar over it. Add the vinegar last though, to keep the leavening reaction.
• Fat: Add up to 1 to 2 Tbsp of additional fat like oil or vegan butter to the recipe.

Keto (low carb, high fat)

• Flour: Swap the white flour for almond flour or coconut flour.
• Sweetener: Replace sugar with Lakanto Monkfruit Sweetener which calls for a 1:1swap that mimics granulated sugar.
• Dairy: Replace dairy with unsweetened plant based milk such as coconut or almond milk.
• Hydration: Almond flour can make baked goods dense. Add 1 -2 tablespoons of additional extra liquid (the same liquid called for in the recipe) to help lighten the texture. Add 1 additional egg to help bind the batter.
• Fat: Add up to 2 Tbsp of additional fat, such as butter or oil to the recipe.

Wholesome (minimally processed)

• Flour: Swap out 1/3 to 1/2 of the white flour with King Arthur white whole wheat flour or King Arthur 100% whole wheat flour or Bob’s oat flour.
• Sweetener: Replace white sugar with maple syrup or honey. Use 3/4 c. honey for every 1 c. sugar. You can also swap out the white sugar with 1:1 swap using natural cane sugar, coconut sugar or date sugar.
• Dairy: Replace dairy with unsweetened plant based milk such as oat, coconut or almond milk.
• Lower Fat: For every 1 c. of butter, use 3/4 c. heart-healthy oil (like canola or extra-light olive) OR 1/2 c. unsweetened applesauce + 1/2 c. oil.

Allergen Free (none of the 9 allergens)

• Flour: Swap out the flour with a premium gluten-free flour such as King Arthur Measure for Measure or use a homemade gluten-free flour blend that does not contain tree nuts or soy. Be sure the flour blend contains xanthan gum or add 1/4 tsp. to 1/2 tsp. per every 1 cup of flour to the recipe. Here is a list of some other gluten-free flours to try.
• Butter: Use unsalted vegan butter sticks such as Violife for best flavor and texture. Add up to 1 to 2 Tbsp of additional fat like oil or vegan butter to the recipe.
• Dairy: Replace dairy with unsweetened plant based milk such as oat or coconut milk. Check the labels to make sure they are soy-free and nut-free.
• Eggs: Replace each egg by adding 1 tsp. baking soda to the batter, then pour 1 Tbsp. white vinegar over it. Add the vinegar last though, to keep the leavening reaction.
• Nuts: Omit all peanuts and tree nuts (almonds, brazil nuts, cashews, hazelnuts, macadamia nuts, pecans, pine nuts, pistachios, or walnuts.
