My sister brought a tub of key lime Greek yogurt to a Sunday breakfast and we had nothing to do with it but make waffles. That was the right call. The yogurt went into the batter, the rest went into a quick topping, and the plate came back empty before the coffee was poured.
These waffles are tangy in a way plain buttermilk ones aren't. The lime yogurt does two jobs: it keeps the crumb soft and it carries the citrus flavor without any extract. You get six waffles from one bowl, which is about right for a small family or two hungry people with leftovers.
One thing worth knowing before you start: this batter is thick. It should be, because that's what gives you a waffle with a crisp shell instead of a soggy one. Don't thin it out to look like pancake batter. It isn't supposed to.
Step-by-Step Instructions
1. Whisk the wet base
Crack the eggs into a large bowl and whisk them with the milk and the first container of key lime yogurt until the mixture is smooth and even. It should look like a thin milkshake with no lumps of yogurt left.
2. Add the dry ingredients
Add the sugar, baking powder, salt, and flour to the same bowl. Whisk until you can't see any dry flour, then stop. A few small lumps are fine, and overmixing makes the waffles tough.
3. Heat and spray the iron
Coat your waffle iron with nonstick spray and let it heat fully. Most irons are ready when the light goes off or when a drop of water sizzles on the grid.
4. Cook the waffles
Pour a heaping half cup of batter into the center of the iron and spread it slightly. Close the lid and cook for 3 to 4 minutes, until the waffle is golden brown and pulls away cleanly. Repeat with the rest of the batter, spraying between batches.
5. Mix the lime topping
In a small bowl, whisk the second container of key lime yogurt with the lime zest and maple syrup. Taste it. If your yogurt is on the tart side, add another half teaspoon of syrup.
6. Serve
Put a warm waffle on each plate, add a dollop of the lime topping, and lay a lime slice on top. Serve right away while the outside is still crisp.
Variations
Blueberry lime
Scatter a small handful of blueberries over the batter right after you pour it, before closing the iron. Don't stir them in, or the batter turns gray.
Extra lime
Add a teaspoon of zest to the batter along with the dry ingredients for a stronger citrus hit.
Coconut finish
Toast two tablespoons of shredded coconut and sprinkle it over the topping. It plays well with the lime.
Smaller batch
The recipe halves cleanly. Use one egg, two thirds cup milk, one container of yogurt, and one cup flour, and keep the baking powder at two teaspoons.
Pro Tips
How to Store Key Lime Waffles
Refrigerator
Let the waffles cool completely, then store them in an airtight container in the fridge for up to 3 days. Keep the topping in its own covered bowl and use it within 2 days.
Freezer
Freeze cooled waffles flat on a sheet pan for an hour, then move them to a freezer bag. They keep for up to 2 months. Don't freeze the topping.
Reheating
Reheat frozen or chilled waffles in a toaster or a 350°F oven for 3 to 5 minutes, until hot and crisp again. Skip the microwave, which makes them rubbery. Add the cold topping after reheating.
Frequently Asked Questions
Q: Can I make the batter ahead of time?
You can mix it the night before and keep it covered in the fridge. It will thicken as it sits, so stir in a splash of milk before cooking. The baking powder loses some lift overnight, so the waffles may come out a little less tall.
Q: What if I don't have key lime Greek yogurt?
Plain Greek yogurt works. Stir 1 teaspoon of lime zest and 1 teaspoon of lime juice into each 5.3-ounce container. Taste the topping before serving and add a little more syrup if it's too tart.
Q: Why did my waffles come out soggy?
Usually it's one of three things: the iron wasn't hot enough, the lid came up too early, or the finished waffles were stacked on a plate. Cook the full 3 to 4 minutes and rest the finished ones on a rack.
Q: Can I use a different flour?
All-purpose flour is what this recipe is built around. Bread flour makes them chewy. If you try whole wheat, swap in half the amount and expect a denser waffle.
Q: How do I know when a waffle is done?
The steam coming out of the iron slows to almost nothing, the lid lifts easily, and the surface is golden brown. If the lid resists, give it another minute.
