🍌 Banana Fudge Recipe Overview

⏱️ Prep Time: 15 minutes (plus chill time)

🍽️ Servings: 25 pieces

🧈 Key Ingredients: Banana flavor, white chocolate chips, sweetened condensed milk

🍬 What to Expect: Creamy, smooth banana fudge with real banana flavor

❄️ Method: No-bake, no candy thermometer - Just melt on the stovetop, mix things together, chill, and slice

We’ve made a lot of fudge over the years, and every recipe we share has been tested until it works the way it should - smooth, creamy, and set just right.

From classic chocolate fudge to fun flavors like cookies and cream, Rolo, or mint chocolate chip, our fudge recipes are designed to be simple, reliable, and totally doable at home.

If you’ve ever had fudge turn grainy or refuse to set, you’re in the right place. We’ve already done the troubleshooting for you.

What you'll need to make this old-fashioned banana fudge with marshmallow fluff:

• 2 teaspoons of banana flavoring  
• ½ teaspoon of yellow food color gel
• ¾ cup of salted sweet cream butter
• ½ cup of half and half
• ⅓ cup of heavy cream
• 1 teaspoon of clear vanilla flavoring
• 3 cups + 2 tablespoons of granulated sugar
• 1¾ cups of white baking chips
• 1 (7-ounce) container of marshmallow fluff
• 2 tablespoons of crushed Nilla wafers

🍫 White Chocolate Chips: White chocolate baking bars can be chopped and used in place of chips. Avoid candy melts or almond bark — they don’t set the same way.

🥛 Sweetened Condensed Milk: This is not interchangeable with evaporated milk, half-and-half, or cream. No reliable substitute here.

🌿 Vanilla Extract: Clear vanilla or vanilla bean paste can be used 1:1.

❌ What Not to Swap

• Do not reduce or omit the sweetened condensed milk.
• Do not use low-sugar or sugar-free chocolate.
• Do not add any real banana. It will add too much moisture and prevent the fudge from setting.

FIRST STEP: Line a 9×9-inch baking dish with parchment paper, making sure the parchment paper goes up all four sides of the baking dish. 

Lightly spray the parchment paper with nonstick cooking spray. Set it aside.

SECOND STEP: Add the banana flavoring and yellow food color gel to a small glass bowl. Stir to combine. Set it aside.

THIRD STEP: Add the butter, half-and-half, heavy cream, and clear vanilla flavor to a three- to four-quart heavy-bottomed saucepan over medium heat.

Stir until the butter is melted.

FOURTH STEP: Add the sugar and continue stirring until the mixture comes to a simmer. This should take between six to seven minutes.

Keep stirring, and allow the mixture to simmer for another three minutes.

Remove from the heat.

FIFTH STEP: Add in the white baking chips. Cover the saucepan and let the mixture rest for three to four minutes. Stir until the white baking chips are melted. 

SIXTH STEP: Add the marshmallow fluff and stir until completely incorporated. 

SEVENTH STEP: Stir in the yellow food gel and banana extract mixture into the fudge. Continue stirring until the color is uniform. 

EIGHTH STEP: Use either a silicone or offset spatula to evenly spread the banana fudge in an even layer into the prepared baking dish. 

Sprinkle the crushed Nilla wafers over the top of the fudge. Cover with aluminum foil.

NINTH STEP: Allow the fudge to sit at room temperature for 30 minutes before chilling in the refrigerator for at least four hours. 

Once the fudge is set, lift the fudge out of the pan with the parchment paper.

Use a large sharp knife to cut the fudge into five slices by five slices, giving you 25 pieces of fudge. 

Keep refrigerated until ready to serve.

Why didn’t my banana fudge set?
This usually means the sugar wasn’t cooked long enough or the mixture never reached a proper simmer.
How to avoid it: Bring the mixture to a gentle simmer with small bubbles around the edges. Continue cooking while stirring until the sugar is fully dissolved before proceeding to the next step.

Why does my fudge taste burnt or look dark?
This happens when the heat is too high or the mixture isn’t stirred consistently.
How to avoid it: Keep the heat at medium and stir constantly. If the mixture starts to darken quickly or smell caramelized, remove it from the heat immediately.

Can I add the banana flavor earlier in the process?
No, adding banana flavor too early can interfere with the structure.
How to avoid it: Always add the banana flavor after the sugar has cooked and the pan has been removed from direct heat.

Can I swap the sweetened condensed milk or cream?
Unfortunately, no. These ingredients are essential for the fudge to set correctly.
How to avoid it: Use the ingredients listed and measure carefully. Substitutions in this recipe will change the texture and prevent proper setting.

Banana Fudge FAQ

Does banana fudge need to be refrigerated?
Banana fudge does not need to be refrigerated right away, but refrigeration is recommended for longer storage.

It can be kept at room temperature in an airtight container for up to 3 days. For best texture and freshness beyond that, store it in the refrigerator.

Can banana fudge be frozen?
Yes, banana fudge freezes very well. Wrap the pieces tightly in plastic wrap and store them in an airtight container or freezer bag for up to 2 months. Thaw in the refrigerator or at room temperature before serving.

Why is my banana fudge grainy?
Grainy banana fudge is usually caused by sugar that wasn’t fully dissolved. This can happen if the mixture didn’t reach a proper simmer, was cooked too quickly, or wasn’t stirred consistently.

How to fix grainy fudge: Cooking the sugar gently and stirring constantly helps create a smooth, creamy fudge texture.
