Full Ingredients
Crepe Batter (makes 8 crepes)
- 1 cup (125 g) all-purpose flour
- 1 tablespoon (12 g) granulated sugar
- 1/4 teaspoon fine salt
- 2 large eggs
- 1 cup (240 ml) whole milk
- 1/2 cup (120 ml) water
- 2 tablespoons (28 g) unsalted butter, melted
- 1 teaspoon vanilla extract
Filling
- 1/2 cup (160 g) Biscoff cookie butter (smooth or crunchy)
- 3 medium ripe bananas, sliced into 1/4-inch (6 mm) rounds
Topping
- 10 Biscoff cookies (about 3.5 oz / 100 g), crushed (a mix of fine crumbs and small chunks is ideal)
- 1/3 cup (80 ml) caramel sauce, warmed
- Optional: pinch of flaky salt (especially nice if your caramel is very sweet)
For Cooking the Crepes
- 1–2 teaspoons unsalted butter for the pan (as needed)
Step-by-Step Instructions
Step 1: Mix a smooth crepe batter
In a medium bowl, whisk together the flour, sugar, and salt. Add the eggs and whisk until a thick, smooth paste forms. Slowly whisk in the milk and water until the batter is loose and mostly lump-free. Whisk in the melted butter and vanilla extract until fully combined.
If you see a few small lumps, don’t worry; they often relax during the rest. For an extra-silky batter, you can blend for 10–15 seconds with an immersion blender or pass through a fine-mesh strainer.
Step 2: Rest the batter for tender crepes
Let the batter rest at room temperature for 20 minutes. This gives the flour time to hydrate and helps the crepes cook up tender instead of chewy.
After resting, whisk the batter again. It should be the consistency of heavy cream. If it seems too thick, whisk in 1–2 tablespoons (15–30 ml) water.
Step 3: Prep the filling and toppings
While the batter rests, slice the bananas into 1/4-inch (6 mm) rounds. Crush the Biscoff cookies (a zip-top bag and rolling pin works well) until you have mostly crumbs with some small crunchy bits.
Warm the cookie butter in the microwave for 10–15 seconds so it spreads easily (it should be soft, not hot). Warm the caramel sauce for 10–20 seconds so it drizzles nicely.
Step 4: Heat the pan and cook the first crepe (test crepe)
Heat a 10-inch (25 cm) nonstick skillet or crepe pan over medium heat. If you have an infrared thermometer, aim for a surface temperature of about 325–350°F (163–177°C).
Lightly butter the pan (about 1/4 teaspoon is enough). Pour in 1/4 cup (60 ml) batter and immediately swirl the pan to coat the bottom in a thin, even layer.
Cook for 45–60 seconds, until the edges look dry and the underside is lightly golden. Flip and cook the second side for 15–25 seconds. Transfer to a plate. (The first crepe is often a little imperfect; consider it your bonus snack.)
Step 5: Cook the remaining crepes and keep them warm
Repeat with the remaining batter, buttering the pan lightly as needed. Adjust the heat if the crepes brown too fast (lower) or take too long (slightly higher). Stack the cooked crepes on a plate as you go.
To keep crepes warm for serving: cover the stack with foil, or place them on a sheet pan in a 200°F (93°C) oven for up to 20 minutes.
Step 6: Fill, fold, and plate
Lay one crepe flat. Spread about 1 tablespoon (20 g) cookie butter over the surface (a thin layer is plenty; you can add more if you like). Arrange banana slices over half of the crepe.
Fold the crepe in half, then fold again into quarters (a triangle). Place on a serving plate. Repeat with remaining crepes.
Step 7: Add the crunchy Biscoff topping and caramel drizzle
Sprinkle each folded crepe with crushed Biscoff cookies, then drizzle with warm caramel sauce (about 2 teaspoons per crepe, or to taste). If desired, finish with a tiny pinch of flaky salt to balance the sweetness.
Serve immediately while the crepes are warm and the cookie butter is creamy.
Pro Tips
- For evenly thin crepes: Pour the batter in, then swirl right away. If you wait even a few seconds, the batter sets and won’t spread.
- Control the heat: Crepes like steady medium heat. If you see smoking butter, your pan is too hot; lower the heat and wipe out any browned butter.
- Make spreading easy: Warm cookie butter briefly so it glides on without tearing the crepe.
- Best banana choice: Use ripe bananas (sweet and fragrant) but not overly soft; they’ll hold their shape and look prettier.
- Crunch factor: Crush cookies into a mix of fine crumbs and small chunks so you get both coverage and crunch.
Variations
- Chocolate-caramel Biscoff crepes: Add 1 tablespoon (8 g) unsweetened cocoa powder to the dry ingredients and increase milk by 2 tablespoons (30 ml) if needed.
- Strawberry-banana swap: Replace 1 banana with 1 cup (150 g) sliced strawberries for a brighter, fruitier version.
- Extra cozy spice: Add 1/2 teaspoon ground cinnamon to the batter for a warmer, spiced crepe.
Storage & Make-Ahead
Crepes: Cool completely, then stack with parchment between them. Store in an airtight container in the refrigerator for up to 2 days or freeze for up to 1 month. Thaw overnight in the fridge.
Reheating: Warm crepes in a dry skillet over medium-low heat for about 10–15 seconds per side, or microwave covered for 10–15 seconds.
Assembled crepes: Best eaten right away. If you must hold them, assemble without bananas, then add bananas and toppings right before serving to prevent browning and sogginess.
