Everybody has made the sad version of this at least once.
You blend something orange, pour it into a bowl, arrange the granola in a careful little row for the photo.
Ninety seconds later the granola is gone.
Sunk without a trace, and you're eating cold soup with wet oats in it.
I did that for about a year before I worked out what was wrong.
It wasn't the recipe. It was the milk.
I was pouring in enough liquid to make the blender's life easy, and paying for it in the bowl.
Now I use half a cup, no more, and I fight the blender for a minute with the tamper instead.
The result is thick enough that a spoon will stand up in it for a couple of seconds before it leans.
Toppings sit exactly where you put them, right down to the last bite.
To be clear about what this is: it's spoonable, not drinkable, and it's eaten from a bowl.
If you want something you can pour into a glass and drink on the way out, that's a smoothie, and it needs twice the liquid.
This one you sit down with.
Cold, thick, spiced, and it takes ten minutes if the potato is already roasted!
Why This Recipe Works
Three things do the heavy work here, and none of them is ice. Ice gives you volume and takes away flavor, and it melts while you're arranging the granola.
- Chilled roasted sweet potato. It's already thick and dense straight out of the fridge, so you're not paying for texture with anything.
- Frozen banana. Cold and creamy, and it sets the surface firm the moment it hits the bowl.
- Almond butter. Two tablespoons is enough to hold everything together and it keeps you full past ten in the morning.
- Dates instead of syrup. They blend into the body of the bowl rather than just sweetening it and thinning it out.
Sound like a small change? It's the whole difference.
What You Need
- Roasted sweet potato (1 ½ cups). Roasted at 400°F until collapsing, then chilled properly. Cold is not optional, warm puree makes a soupy bowl.
- Frozen bananas (2 small). Peeled and broken into pieces before freezing. A whole frozen banana will strain your blender.
- Whole milk (½ cup). Measured. Not poured by eye, and not topped up because the blender is struggling.
- Medjool dates (2). Pitted. Soak them in hot water for five minutes if they're firm.
- Almond butter (2 tablespoons). Peanut butter works and tastes stronger.
- Cinnamon (¾ teaspoon) and nutmeg (⅛ teaspoon). Enough spice to taste like something, not enough to taste like pie.
- Vanilla (1 teaspoon).
- Salt (¼ teaspoon). More than you'd expect in a sweet bowl, and it's what makes the flavors read.
- Toppings. Granola, sliced banana, toasted pecans, shredded coconut.
How to Make It
Step 1: Roast and Chill
Bake whole sweet potatoes at 400°F for 45 to 55 minutes until they're slumped and leaking syrup, then cool and refrigerate for at least 2 hours.
I do this the night before, always.
Step 2: Load in Order
Milk first, then the dates, almond butter, sweet potato, spices and vanilla, then the frozen banana pieces last.
Step 3: Blend Thick
Blend on high, working the tamper down through the mixture, for 60 to 90 seconds.
It will sound unhappy and it will climb the sides.
Stop and scrape it down twice. Do not add milk.
Step 4: Spoon and Level
Spoon it into two bowls, don't pour it, and level the surface flat.
Add the toppings straight away and eat it straight away.
Thick Enough to Hold Toppings
The spoon test settles it. Stand a spoon upright in the middle of the bowl and let go.
It should stay put for two or three seconds before it slowly leans over.
If it falls flat immediately, you've made a smoothie in a bowl.
- Add milk by the tablespoon. Never by the splash. One tablespoon changes more than you'd think at this thickness.
- Use the tamper. It's there so you can blend thick mixtures without adding liquid. Most runny bowls are just impatience.
- Scrape the sides. Twice, minimum. The blade only works on what it can reach.
- Ice is the wrong fix. It thickens for four minutes and then dilutes everything you just made.
- Chill the bowls. Five minutes in the freezer buys you real time at the table.
Common Smoothie Bowl Mistakes
Almost every failed bowl comes down to one of these five. I've made all of them, most of them more than once.
- Warm puree. Sweet potato straight from the oven melts everything else in the blender. Chill it properly.
- Too much liquid. The single biggest cause. Measure it, and add more only if the blender genuinely cannot move.
- Wet toppings. Fresh berries and canned fruit shed juice into the surface and soften it fast. Keep the wet things to a minimum.
- Filling the bowl to the rim. Toppings need somewhere to sit. Fill it about two thirds and leave a clear band of bowl showing.
- Letting it stand. It softens within a few minutes at room temperature. Photograph fast or don't photograph at all.
Toppings and How to Arrange Them
Group them in bands across the surface instead of scattering them. It's not just for looks, it means every spoonful gets a bit of everything instead of all the coconut in one go.
- Granola. A band across one side. This is the crunch, so be generous with the band and not with the depth.
- Sliced banana. Overlapping coins in a line down the middle.
- Toasted pecans. Chopped, along the other side.
- Shredded coconut. A narrow strip between the bands.
- Heavy things last. And near the edge of the bowl, where the mixture is deepest and firmest.
How to Customize
- Protein. One scoop of vanilla protein powder, plus one extra tablespoon of milk.
- Chocolate. A tablespoon of cocoa powder and one extra date.
- Peanut butter. Swap it straight for the almond butter, and add a little more salt.
- More spice. A pinch of ginger and cloves alongside the cinnamon.
- Dairy free. Almond or oat milk in place of the whole milk, same quantity.
Make Ahead and Batch
- Roast in bulk. Four potatoes at once, chilled and portioned into containers.
- Freezer packs. Sweet potato, banana, dates and spices in a bag. Add the milk and almond butter and blend.
- Blended ahead. It holds in the freezer for a couple of hours, then needs a hard stir before serving.
- Overnight. Don't. It freezes solid and thaws grainy.
Get the thickness right once and you'll never go back to the sinking granola version. I promise.
Recipe
Sweet Potato Smoothie Bowl
Ingredients
For the Bowls
- 1 ½ cups roasted sweet potato flesh chilled at least 2 hours
- 2 small frozen bananas peeled and broken into pieces
- ½ cup whole milk measured, plus more only if needed
- 2 medjool dates pitted
- 2 tablespoon almond butter
- ¾ teaspoon ground cinnamon
- ⅛ teaspoon ground nutmeg
- 1 teaspoon vanilla extract
- ¼ teaspoon fine salt
To Top
- ½ cup granola
- 1 small banana sliced
- 2 tablespoon toasted pecans chopped
- 1 tablespoon shredded coconut
Instructions
Roast and Chill
- Bake whole sweet potatoes at 400F for 45 to 55 minutes until they slump and leak syrup. Cool, scoop out the flesh, and refrigerate at least 2 hours. Warm puree makes a soupy bowl.
Blend Thick
- Pour the measured milk into the blender first, then add the dates, almond butter, chilled sweet potato, cinnamon, nutmeg, vanilla and salt. Add the frozen banana pieces last.
- Blend on high for 60 to 90 seconds, working the tamper down through the mixture and scraping the sides twice. Do not add more milk unless the blade genuinely cannot move, and then only 1 tablespoon at a time.
- Check the thickness: a spoon stood upright in the middle should stay put for 2 to 3 seconds before it leans.
- Spoon the mixture into two bowls rather than pouring it, and level the surface flat, filling each bowl about two thirds so there is room for the toppings.
- Arrange the granola, sliced banana, pecans and coconut in bands across the surface and eat straight away, before it softens.
Notes
- Chill the sweet potato: at least 2 hours. Warm puree is the fastest way to a runny bowl.
- Measure the milk: half a cup. Add more only by the tablespoon, and only if the blade cannot move.
- Use the tamper: most thin bowls are impatience, not a bad recipe.
- No ice: it thickens briefly and then dilutes everything.
- Fill two thirds: toppings need somewhere to sit, and a rim of bowl showing keeps them from sliding off.
- Eat it immediately: it softens within a few minutes at room temperature.
