Cooking Steps

You'll start by mixing the flour and water until you achieve a smooth, lump-free batter that flows easily.

Next, spread the dough thinly to the edges of your hot griddle and arrange fresh banana slices in the center before folding the edges inward to form a neat square shape.

Finally, drizzle warm condensed milk over your crispy roti gluay, allowing it to seep into the layers and create that signature Thai street food experience.

Step 1. Mix Flour and Water Thoroughly

To begin the essential first step, combine 2 cups of all-purpose flour with 1/2 cup of lukewarm water in a large mixing bowl.

You'll want to mix these ingredients thoroughly until you achieve a smooth, elastic dough. If the mixture feels too dry, add water one tablespoon at a time. If it's too wet, incorporate small amounts of flour until you reach the right consistency.

The water ratio is vital - you're aiming for a dough that's pliable but not sticky. While all-purpose flour works well, you can experiment with different flour types like cake flour for a softer texture.

Keep kneading the dough for about 5-7 minutes until it becomes smooth and springs back when you press it with your finger.

Step 2. Spread Dough to Edges

After your dough has rested for 15-20 minutes, divide it into golf ball-sized portions.

Place one portion on an oiled surface and flatten it slightly with your palm. Using proper dough handling techniques, start from the center and work outward, gently stretching the dough into a thin circular shape about 8 inches wide.

For the edge technique, use your fingertips to press and spread the dough evenly, ensuring there aren't any thick spots or tears.

You'll want to create a uniformly thin layer that's almost translucent but still strong enough to hold the filling. If the dough starts sticking, add a small amount of oil to your hands.

Keep rotating the dough as you work to maintain an even circular shape.

Step 3. Add Sliced Banana Pieces

Place three evenly sliced banana pieces diagonally across the center of your stretched dough, leaving about 2 inches of space between each slice.

For the best results, use ripe Thai Namwa bananas, though Cavendish or Lady Finger varieties will work well too. The bananas should be firm enough to hold their shape but ripe enough to provide natural sweetness.

You can experiment with different flavor combinations by adding a sprinkle of cinnamon, a dash of sugar, or even a few chocolate chips between the banana slices.

If you're using larger bananas, cut them into 1/2-inch thick pieces to guarantee they'll cook evenly with the roti.

Make sure the banana slices don't touch the edges of the dough, as you'll need space for folding in the next step.

Step 4. Fold Edges Into Square

Gently fold each edge of the dough inward to form a neat square shape, overlapping the corners slightly to seal in the banana pieces. Your square folding technique will determine how well the filling stays contained and affects the final pancake presentation.

Make certain each fold creates a tight seal to prevent any banana from escaping during cooking.

Start with the bottom edge, folding it upward about one-third of the way to cover the bananas.
Fold the left and right sides inward at angles, creating triangular flaps that meet in the middle.
Finally, fold the top edge down to complete the square, tucking any loose corners underneath to secure them.

Press down lightly on the edges with your spatula to guarantee they're well-sealed before cooking the folded roti.

Step 5. Drizzle Melted Condensed Milk

The delicate drizzling of sweetened condensed milk transforms your roti gluay into a decadent Thai street food treat. While the roti's still hot, you'll want to drizzle warm condensed milk in a zigzag pattern, ensuring even distribution across the pancake's surface.

For the best drizzle technique, hold your spoon about 6 inches above the roti and move your hand in steady, fluid motions. The condensed milk's rich, creamy texture adds both visual appeal and a sweet, caramelized flavor that perfectly complements the bananas inside.

Don't overdo it - you're aiming for thin, artistic lines rather than heavy pools of sweetness. The milk's natural proteins and calcium benefits are a bonus, but it's the way it seeps into the crispy layers that makes this final touch irresistible.
