Ingredients for 3 ingredient marshmallow bread
Three pantry staples transform into restaurant-quality marshmallow bread with zero fuss.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 cups | Unbleached preferred for lighter texture |
| Mini Marshmallows 🍥 | 12 oz | Standard size, not jumbo |
| Unsalted Butter 🧈 | ½ cup | Softened to room temperature |
| Granulated Sugar 🍚 | ½ cup | White sugar for neutral sweetness |
| Vanilla Extract 🌸 | 1 tsp | Pure vanilla for authentic flavor |
| Baking Powder 🧂 | 1 tsp | Ensures proper rise |
| Salt 🧂 | ¼ tsp | Fine sea salt for balance |
| Milk 🥛 | ¼ cup | Any variety works |
The flour is where the magic happens—King Arthur or Gold Medal brands give the best texture, but any all-purpose works in a pinch. Marshmallows? Mini size is non-negotiable—they melt perfectly without sinking. Grab a 12-ounce bag (the standard size) from the baking aisle. Butter needs to be soft but not melted—press the bowl with your finger, it should leave a slight indent. For sugar, domestic white sugar is ideal, but brown sugar adds a caramel note if you’re feeling adventurous. The vanilla extract should be pure, not imitation—McCormick or Nielsen-Massey are reliable brands.
No baking powder? 1/4 tsp baking soda plus 1/2 tsp cream of tartar works as a substitute. Out of milk? Water plus 1/2 tsp vanilla extract keeps things moist. Marshmallows too expensive? Mini marshmallow fluff (from the baking aisle) gives a similar texture. Want extra richness? Add 1 tbsp melted butter to the mix. For a deeper flavor, swap 1/4 cup of the flour for cornstarch—it creates a lighter crumb. Pro tip: Toast the marshmallows for 2 minutes in the microwave before mixing for extra gooeyness.
This dough keeps for 24 hours in the fridge—perfect for prepping ahead. For longer storage, freeze the unbaked loaf for up to 3 months. Once baked, let it cool completely before slicing—patience prevents soggy layers. Store wrapped at room temperature for 2 days or refrigerate for 5 days. The flavor actually improves overnight as the marshmallow melts further. Slice with a serrated knife for clean cuts, and serve warm for maximum gooeyness.

Step-by-step instructions for 3-Ingredient marshmallow bread
This one-bowl wonder delivers melt-in-your-mouth marshmallow bread with minimal effort.
Melt Butter and Sugar Together
In a large microwave-safe bowl, combine the 0.5 cup unsalted butter and 0.5 cup granulated sugar. Microwave on high for 30-second intervals, stirring between each, until the mixture is completely melted and smooth. You should see a glossy, golden liquid with no remaining butter chunks. This step creates the perfect base for binding all ingredients together.
Real talk: Don’t rush this part. If you see any butter lumps, give it another 10 seconds. Cold butter won’t incorporate properly with the dry ingredients, leading to dense bread. The mixture should feel warm to the touch but not hot enough to burn your fingers.
Mix in Wet Ingredients
Add the 1 tsp vanilla extract, 0.25 cup milk, and 0.25 tsp salt to the melted butter-sugar mixture. Stir vigorously with a wooden spoon or silicone spatula until everything is fully combined. The mixture will look like a pale, creamy batter. This is where the magic begins—these wet ingredients activate the baking powder and create the perfect texture foundation.
Here’s the thing—don’t overmix. Just until smooth. You want to maintain some small lumps in the butter mixture, as this helps create that signature marshmallow bread texture. The batter should coat the back of your spoon but still be pourable.
Fold in Dry Ingredients and Marshmallows
In a separate bowl, whisk together the 2 cups all-purpose flour and 1 tsp baking powder. Gradually add this dry mixture to the wet ingredients while stirring constantly. Once combined, fold in the 12 oz mini marshmallows using a spatula. Be gentle—you want to distribute them evenly without crushing any. The dough will be thick and sticky, almost like a very wet cookie dough.
This is the moment that matters: Make sure all the marshmallows are coated with batter. If you see any bare marshmallows, gently fold them in with more batter. The key to perfect marshmallow bread is even distribution—every bite should have that gooey marshmallow surprise.
Bake to Golden Perfection
Preheat your oven to 350°F. Grease a 9×5-inch loaf pan with butter or line it with parchment paper for easy removal. Transfer the dough to the prepared pan and spread it evenly. Bake for 45-50 minutes until the top is golden brown and a toothpick inserted in the center comes out clean. The edges should pull away slightly from the pan, and you’ll smell that unmistakable sweet, buttery aroma.
Don’t open the oven during baking—this can cause the bread to sink. If you’re worried about overbrowning, tent the pan loosely with aluminum foil after 30 minutes of baking. The bread is done when it springs back slowly when pressed gently in the center.
Cool and Serve
Remove the bread from the oven and let it cool in the pan for 10 minutes. Then transfer it to a wire rack to cool completely. This cooling time is crucial—it allows the bread to set properly and prevents it from becoming gummy. While cooling, you’ll notice the marshmallows soften and meld beautifully with the bread, creating that signature marshmallow bread texture.
Slice the bread into ¼-inch thick pieces and serve warm for the best experience. Each bite should deliver a perfect balance of tender bread and gooey marshmallow goodness. Store any leftovers in an airtight container at room temperature for up to 3 days, or freeze for up to 3 months for freshness.
Pro Tips For Making 3 Ingredient Marshmallow Bread
- Melt Butter Slowly: I learned this the hard way—dumping cold butter into the hot sugar mix makes clumps that refuse to dissolve. Instead, cut the butter into small cubes and let them melt gradually into the sugar over medium heat. This keeps the mixture smooth and prevents lumps that turn into weird, chewy spots in your bread.
- Toast Marshmallows First: Skip the raw marshmallow step—toss them in a dry pan over low heat for 2-3 minutes until they puff and turn golden. This caramelizes their edges and cuts through the sweetness. Just don’t walk away; they burn faster than you’d think.
- Stop When It Springs: The bread’s done when a toothpick comes out clean and the top springs back when pressed—no waiting for a golden crust. Overbaking turns it dry; underbaking leaves it gummy. Trust the bounce, not the color.
- Use Room-Temp Butter: Cold butter creates pockets of resistance in the dough, leading to dense spots. Let it sit out for 30 minutes before mixing—just enough to soften but not melt. Your bread will rise evenly, and the texture will be light, not heavy. (Yes, even if you’re impatient like me.)
Essential equipment for this recipe
One-Bowl Wonder
This recipe thrives in a large microwave-safe mixing bowl (at least 4-quart capacity). I use a Pyrex glass bowl because it handles heat well and won’t crack. If you don’t have one, a stainless steel mixing bowl works too—just make sure it’s microwave-safe.
The bowl needs to be big enough to hold all ingredients without overflowing when you fold in marshmallows. 🍥
Measuring Essentials
For accurate results, use a digital kitchen scale for the marshmallows (they should weigh 12 ounces total). A 16-ounce bag of mini marshmallows gives you the perfect amount.
For dry ingredients, a medicine cup works for the baking powder and salt, while a dry measuring cup ensures proper flour volume. I keep my measuring tools in a cute little caddy on my counter for easy access. 🧂
Pan Prep Must-Haves
A 9×5-inch loaf pan is non-negotiable for this recipe. I recommend a non-stick pan for easy removal, but if yours isn’t non-stick, grease it generously with butter or baking spray. Line the bottom with parchment paper if you’re worried about sticking—just make sure it doesn’t peek over the edges.
The pan should fit comfortably in your oven without touching the sides. ⏰
Mixing Tools
You’ll need a wooden spoon or silicone spatula for mixing—both work great, but silicone is easier to clean. A separate bowl for whisking dry ingredients is helpful, but if you’re short on space, just whisk them directly in your mixing bowl.
For folding in marshmallows, a flexible spatula helps prevent crushing. Pro tip: Keep a paper towel handy for sticky fingers. 🧑🍳
Oven Thermometer
Ovens run hot or cold, and this recipe depends on precise temperature control. I always use an oven thermometer (like the Thermoworks Oven Thermometer) to ensure accurate 350°F readings.
If your oven runs hot, reduce the temperature to 340°F—this prevents overbrowning. A consistent temperature guarantees even baking and that perfect golden crust. 🌡️
Cooling Essentials
After baking, transfer the bread to a wire cooling rack to prevent sogginess. If you don’t have one, a plate lined with a clean kitchen towel works in a pinch.
For slicing, a sharp serrated knife (like the Mercer Culinary Genesis) gives clean cuts. Let the bread cool completely before slicing—this ensures neat, gooey slices every time. 🔪

Frequently asked questions
Can I make this marshmallow bread without a loaf pan?
Yes! For a rustic look, spread the dough on a parchment-lined baking sheet and bake for 35-40 minutes at 350°F. You’ll get a free-form marshmallow bread that’s perfect for sandwiches or breaking into pieces. Just reduce baking time slightly since edges cook faster without pan confinement.
Why did my marshmallow bread turn out dense instead of light?
This usually happens when butter isn’t melted properly or marshmallows aren’t evenly distributed. Make sure butter is completely liquid (no lumps) and fold marshmallows gently to avoid crushing. Also check your oven temperature—if it’s too hot, the bread will bake too quickly and become dense. Try 340°F if your oven runs hot.
How can I make this bread extra gooey?
For maximum marshmallow goodness, try these pro tips: Use 14 oz marshmallows instead of 12 oz, and microwave them for 2 minutes before mixing to soften them. Also, brush the top with melted butter after baking and let it soak in for 5 minutes before cooling. The result? A cloud of marshmallow in every bite.
Can I substitute regular marshmallows for mini marshmallows?
Not recommended! Regular marshmallows are too large and won’t melt evenly, creating pockets of unmelted marshmallow. If you absolutely must use them, chop 8 large marshmallows into small pieces first. For best results, stick with mini marshmallows—they melt perfectly and distribute evenly throughout the bread.
How should I store leftovers to keep them fresh?
Wrap cooled bread tightly in plastic wrap or aluminum foil, then place in an airtight container. Store at room temperature for 2 days or refrigerate for up to 5 days. For longer storage, freeze slices wrapped individually—they’ll stay fresh for 3 months. To revive, warm slices in the microwave for 10-15 seconds for that fresh-baked gooeyness.
