This Ninja Belgian waffle recipe makes thick, golden waffles with crisp edges and a soft, tender center using a standard baking-powder batter. Belgian waffles are associated with Belgium, where Brussels and Liège waffles are distinct regional styles; this easy, buttermilk-based version is Brussels-inspired rather than a yeast-raised or pearl-sugar Liège waffle.
Ingredients
- 2 cups (250 g) all-purpose flour
- 2 tablespoons (25 g) granulated sugar
- 1 tablespoon (12 g) baking powder
- ½ teaspoon (3 g) fine salt
- 2 large eggs (about 100 g without shells), at room temperature if convenient
- 1¾ cups (420 ml) buttermilk, shaken before measuring
- 6 tablespoons (85 g) unsalted butter, melted and cooled slightly
- 1 teaspoon (5 ml) vanilla extract
- Neutral oil or nonstick cooking spray, as needed for the waffle plates
Instructions
- Preheat the waffle maker. Set up your Ninja Belgian waffle maker according to its manual and preheat it while you mix the batter; allow about 4 minutes, or follow its ready light or audible signal. Models differ in plate shape, browning controls, and whether the plates need greasing, so use the maker’s instructions for those details. If your model has a browning setting, start around medium or medium-high.
- Combine the dry ingredients. In a large bowl, whisk the flour, sugar, baking powder, and salt until the baking powder is evenly distributed. Breaking up small lumps now helps prevent pockets of leavener in the finished waffles. In a second bowl or large measuring jug, whisk the eggs, buttermilk, melted butter, and vanilla until blended.
- Make a gently mixed batter. Pour the wet mixture into the dry ingredients. Stir with a whisk or spatula just until no large dry patches remain. A few small lumps are fine; mixing until completely smooth can develop the flour’s gluten and make waffles chewy. The batter should be thick but pourable. If it seems unusually stiff, stir in buttermilk 1 tablespoon (15 ml) at a time.
- Prepare the plates and fill the maker. Check whether your Ninja model calls for oiling the plates. If needed, brush on a very thin film of neutral oil or use a light coating of nonstick spray; excess oil can smoke or make the waffles greasy. Spoon enough batter into the center to cover the lower grid when the lid closes, without filling it to the rim. The right amount varies with the machine’s plate size, so begin with less than you think you need and adjust after the first waffle.
- Cook the waffles. Close the lid and cook until the maker indicates the waffle is ready, or until it is deep golden and releases without tearing, usually about 4 minutes per waffle. If your model has adjustable browning, add time or choose a darker setting for a crisper exterior. Avoid lifting the lid too early: the waffle can split before its structure sets. For egg safety, USDA FSIS lists 160°F (71°C) as the safe minimum internal temperature for egg dishes; check the center of a fully cooked waffle with a clean food thermometer when practical.
- Repeat and keep warm if needed. Transfer each waffle to a wire rack rather than stacking it, which traps steam and softens the crust. Cook the remaining batter in batches, lightly re-greasing the plates only if the maker’s instructions call for it or waffles begin to stick. To serve several waffles together, hold them in a single layer on a rack in a 200°F (93°C) oven while the remaining batches cook. The oven hold is optional and is not included in the 20-minute cook estimate.
- Serve promptly. Add toppings just before serving so they do not soak into the crisp surface. If you are cooking for different appetites, leave some waffles plain and put toppings on the table for everyone to add.
Tips
- Measure flour lightly. Spoon it into the measuring cup and level the top rather than packing it down. Too much flour makes a dense batter; weighing 250 g is the most consistent option.
- Use the maker’s indicators as a guide, not a guarantee. Ninja waffle makers vary, and the first waffle is useful for judging how much batter to use and how dark your preferred setting should be. Keep the lid closed until the ready signal or until steam has mostly subsided.
- Let melted butter cool briefly. Very hot butter can partially cook the eggs when the wet ingredients are combined. If you do not have buttermilk, use 1¾ cups (420 ml) regular milk mixed with 1 tablespoon (15 ml) lemon juice; leave it for 5 minutes before using. The result is a little less tangy and may be slightly less tender.
- Keep finished waffles crisp. Set them directly on a rack, not a plate and not in a stack. If you need to wait more than a few minutes, use the low oven hold described above; covering them will trap steam and soften their edges.
Serving Suggestions
Serve the waffles hot with butter and maple syrup for a familiar breakfast, or add berries, sliced bananas, peaches, or stewed apples. A spoonful of yogurt or lightly whipped cream adds a cool, creamy contrast. For a fuller brunch plate, pair one or two waffles with scrambled eggs, fruit, and coffee or tea; serve any savory sides separately so their moisture does not soften the waffles.
For a simple topping bar, set out syrup, butter, fresh fruit, toasted nuts, and a small bowl of powdered sugar. Put wet toppings on at the table rather than assembling waffles ahead of time. These waffles are substantial, so one large waffle per person with fruit and toppings is often enough for breakfast, while bigger appetites may want two.
Variations
Make them more Brussels-style in texture: Separate the eggs, mix the yolks into the wet ingredients, and beat the whites to soft peaks in a clean bowl. Fold the whites into the completed batter just before cooking. This adds air and gives the waffles a lighter texture, but it takes extra time and the batter should be cooked soon after folding.
Add a little spice: Whisk ½ teaspoon (1 g) ground cinnamon or ¼ teaspoon (0.5 g) ground cardamom into the dry ingredients. These are optional flavor additions, not requirements for Belgian waffles. A small amount of finely grated lemon zest also works well with berries.
Use chocolate or nuts: Fold in up to ½ cup (85 g) mini chocolate chips or ⅓ cup (40 g) finely chopped toasted pecans after mixing. Keep additions modest so batter can still spread and cook through. Chocolate can make the plates messier, so clean the maker according to its manual once it has cooled.
Try a whole-wheat blend: Replace up to ½ cup (60 g) of the all-purpose flour with whole-wheat flour. The waffles will taste nuttier and may be a little denser; if the batter becomes too thick, add buttermilk 1 tablespoon (15 ml) at a time. This baking-powder batter is not a traditional Liège waffle: that style typically uses a yeast-raised dough and pearl sugar, which caramelizes on the iron and requires a different method.
Storage and Reheating
Let extra waffles cool on a rack, then refrigerate them in a covered container within 2 hours of cooking. They keep for 3 to 4 days in the refrigerator. For longer storage, freeze the cooled waffles in a single layer until firm, then place them in a freezer-safe bag with parchment between layers; use within about 2 months for best quality. Label the bag with the date so you can keep track.
Reheat refrigerated or frozen waffles in a toaster, toaster oven, or air fryer until hot and crisp; frozen waffles can go straight into the toaster if its slots accommodate them. A 350°F (175°C) oven for about 5 to 8 minutes works well for several waffles at once, with a few extra minutes if they are frozen. Avoid the microwave when crispness matters, since it warms waffles quickly but makes them soft. USDA FSIS recommends reheating leftovers to 165°F (74°C); check the center with a food thermometer if you need to verify the temperature.
Frequently Asked Questions
Can I make this batter ahead?
It is best mixed shortly before cooking because baking powder starts reacting when it meets liquid, and the batter can lose some lift while sitting. If you need to save time, measure the dry ingredients and wet ingredients separately the night before, cover them, and refrigerate the wet mixture. Combine them just before preheating and cooking.
Why are my waffles soft instead of crisp?
They may need a little more time in the maker, or they may be soft because they were stacked while hot. Cook until deeply golden and the waffle releases cleanly, then place it on a wire rack. A low oven can keep a batch warm without trapping as much steam as a covered plate.
Can I use regular milk instead of buttermilk?
Yes. Stir 1 tablespoon (15 ml) lemon juice or white vinegar into 1¾ cups (420 ml) milk and let it stand for 5 minutes. This provides some acidity and works well in the batter, though the flavor will be less tangy than with cultured buttermilk. Do not reduce the baking powder when making this swap.
How much batter should I put in my Ninja waffle maker?
There is no single amount for every Ninja model because Belgian plates differ in size and depth. Begin with enough to cover most of the lower grid without reaching the edge, close the lid, and follow the manual’s filling guidance. If batter escapes, use less next time; if the waffle leaves large uncovered sections, add a little more.
Can I make these waffles without eggs?
This recipe depends on eggs for structure and browning, so an egg-free substitute may change the texture. A commercial egg replacer can work if its package directions recommend it for waffles or baking, but results vary by product. Make a small test batch first, and check that the center is fully cooked before serving.
Can I make the waffles gluten-free?
You can try a cup-for-cup gluten-free flour blend that includes a binder such as xanthan gum, but blends absorb liquid differently. Start with the same amount by volume, then adjust with a little extra buttermilk if the batter is too thick. Cook one test waffle first; it may need a longer cook time and can be more fragile when hot.
