Banana Bread Syrup Recipe

Makes ~10 ounces | Stores up to 2 weeks

Ingredients

• ½ cup chopped walnuts
• 2 ripe bananas, mashed
• ½ cup dark brown sugar
• ½ cup granulated sugar
• 1 cup water
• ½ teaspoon ground cinnamon
• Pinch of ground nutmeg (optional)
• Pinch of salt
• 1 teaspoon vanilla extract

Instructions

1. Toast the walnuts
   Add the walnuts to a saucepan and heat over medium-low heat, stirring until fragrant (about 5 minutes).
2. Combine and Simmer
   Once fragrant, add in the mashed bananas, sugars, water, cinnamon, nutmeg, and salt. Stir until the sugar is fully dissolved. Bring to a gentle simmer over medium heat and cook for 10 minutes, until the bananas are very soft and the syrup has thickened slightly.
3. Strain
   Remove from heat and strain through a fine-mesh sieve, pressing gently to extract all the syrup. Set the drained banana and walnuts aside (see Note).
4. Finish
   Stir in the vanilla extract. Let cool, then transfer to a jar or bottle.
5. Store
   Refrigerate for up to 2 weeks. Shake before using.

Note: Add the leftover banana and walnuts to oatmeal, chia pudding, or yogurt. You could also add them to pancake or waffle batter before cooking.

How to Use Banana Bread Syrup

This syrup is incredibly versatile and adds cozy, bakery-style flavor to both drinks and breakfast favorites.

Use it in:

• Banana Bread Lattes (hot or iced)
• Cold brew with a splash of milk or cream
• Iced coffee or shaken espresso drinks
• Drizzled over pancakes or waffles
• Stirred into oatmeal or yogurt

Suggested amount:
Start with 1–2 tablespoons per drink, then adjust to taste.

Sugar-Free Banana Bread Syrup Option

A sugar-free version is possible, though the texture will be slightly lighter than the original.

To make it sugar-free:

• Replace the granulated sugar with allulose and replace the dark brown sugar with your favorite brown sugar alternative

What to Do With the Leftover Banana Walnut Mixture

After straining the syrup, you’ll be left with a soft banana walnut mixture — and it’s too good to throw away. While it’s not as sweet as the syrup itself, it’s still full of flavor and works beautifully in a few simple ways.

Here are some easy ideas:

• Stir into oatmeal or overnight oats for extra banana bread flavor
• Mix into yogurt with a drizzle of honey or maple syrup
• Spread on toast or English muffins like a soft banana jam
• Add to pancake or waffle batter for a banana walnut twist
• Swirl into muffin or quick bread batter before baking

If you’re not using it right away, store the mixture in an airtight container in the fridge for up to 2–3 days.

Flavor Notes & Tips

• The walnuts don’t make the syrup “nutty” in an overpowering way — they add depth and warmth, similar to banana bread with chopped nuts. Of course omit the walnuts if you’re allergic or not a fan.
• Toasting the walnuts first gives an even deeper bakery-style flavor.
• If you want more walnut presence, add ¼ teaspoon walnut extract along with the vanilla.
