  • Easy to make with simple pantry ingredients
  • No electric mixer required
  • Ready in under 30 minutes
  • Perfect for breakfast, dessert, or snacks
  • Easy to customize with different flavors and toppings

Ingredients

  • 1 large egg
  • 50 g whole milk
  • 25 g neutral oil (corn, sunflower, or vegetable oil)
  • 20–30 g powdered sugar
  • 70 g cake flour (low-protein flour)
  • 10 g cornstarch
  • 2 g aluminum-free baking powder
  • Optional: ½ teaspoon vanilla extract

Equipment

  • Bubble waffle pan (stovetop or electric)
  • Mixing bowl
  • Whisk
  • Measuring scale or measuring cups
  • Pastry brush or paper towel for greasing

Instructions

1. Mix the Wet Ingredients

In a medium bowl, whisk together:

  • Egg
  • Milk
  • Oil

Mix until smooth.

2. Add Sugar

Whisk in the powdered sugar until completely dissolved.

If using vanilla extract, add it now.

3. Add the Dry Ingredients

Sift together:

  • Cake flour
  • Cornstarch
  • Baking powder

Gradually whisk into the wet mixture until a smooth batter forms.

Do not overmix.

4. Rest the Batter

Let the batter rest at room temperature for 15–20 minutes.

This helps hydrate the flour and creates a softer, chewier texture.

5. Preheat the Waffle Pan

Heat the bubble waffle pan over medium heat until fully hot.

Lightly grease both sides with oil.

6. Cook the Waffles

Pour enough batter into the pan to fill it about three-quarters full.

Close the lid immediately and flip the pan over.

Cook for 2–3 minutes, flip again, and cook another 2–3 minutes, or until the waffle is golden brown and crisp.

7. Cool and Serve

Carefully remove the waffle and place it on a wire rack for a minute to crisp slightly.

Serve warm.


Tips for Perfect Bubble Waffles

  • Rest the batter before cooking.
  • Use cake flour for the best chewy texture.
  • Fully preheat the waffle pan before adding batter.
  • Lightly grease the pan before each batch.
  • Avoid overmixing the batter.
  • Cool the waffles on a wire rack to maintain crispness.

Flavor Variations

Chocolate

Replace 10 g of the flour with unsweetened cocoa powder.

Matcha

Add 1 teaspoon matcha powder.

Vanilla

Increase vanilla extract for a richer flavor.

Savory

Omit the sugar and add shredded cheese, herbs, or chopped scallions.


Topping Ideas

Serve Bubble Egg Waffles with:

  • Whipped cream
  • Fresh strawberries
  • Blueberries
  • Bananas
  • Chocolate sauce
  • Nutella

Storage

Helpful Tips

  • Batter should have the consistency of pancake batter.
  • If the batter is too thick, add a little milk.
  • If it’s too thin, whisk in a small amount of flour.
  • Flip the pan immediately after closing it for evenly shaped bubbles.
  • Serve immediately for the crispiest texture.

Frequently Asked Questions

Can I make Bubble Egg Waffles without a bubble waffle pan?

Yes. A regular waffle maker can be used, although the waffles will not have the signature bubble shape.

Why are my waffles not crispy?

The pan may not be hot enough, or the waffles may not have cooked long enough. Cooling them on a wire rack also helps maintain crispness.

Can I prepare the batter ahead of time?

Yes. Refrigerate the batter for up to 24 hours and stir gently before using.

Can I freeze Bubble Egg Waffles?

Yes. Allow them to cool completely, freeze between parchment paper, and reheat in the oven or air fryer until crisp.

Can I double the recipe?

Absolutely. Simply double all ingredients while following the same preparation and cooking steps.
