Black Forest Chocolate Frappe with Cherries and Banana Step-by-step instructions

Before you start

Gather everything before you start blending, so the frappe goes from fruit to glass without delay. Set a wooden cutting board on the counter with a chef's knife, a fine metal grater and a small bowl beside it. Rinse the dark cherries and dry them with a towel. Pit them, then cut each cherry in half and set the halves in a small dish. Peel the banana and slice it into rounds. Place the roasted almonds in a small bowl so they are easy to add. Have the dark chocolate ready in one piece and the milk measured in a cup. Fill a tall glass with ice water briefly, then empty it, so the glass is cold and stays cold while you work.

Instructions

Prepare the fruit and chocolate

1. 1Prepare the fruit and nuts
   Pit the dark cherries and cut them in half with a chef's knife. Slice the ripe banana into rounds. Set the roasted almonds beside the fruit on a wooden cutting board so everything is ready to add.
   Look for Cherry halves are clean and pit-free, banana rounds are even and pale yellow.
   Tip Choose a banana that is ripe with brown freckles for natural sweetness and a smooth texture.
2. 2Grate the dark chocolate
   Grate the block of dark chocolate on a fine metal grater over the board. Let the thin chocolate curls fall in a loose pile so they can be added straight to the blender.
   Look for Fine curls fall loosely, with no large chunks left on the grater.
   Tip Chill the chocolate for 10 minutes first so it grates into finer, cleaner curls.

After this phase, the cherries are pitted and halved, and the banana is sliced into even rounds. The almonds sit in a small bowl, and the chocolate is grated into fine, loose curls that fall easily onto the board. Look for clean cherry halves with no stones and banana rounds of a similar thickness, so they blend at the same rate.

The chocolate should look like a pile of thin shavings rather than dust or large chunks. Before you go on, check the cutting board and the grater for stray pieces of fruit or chocolate, and tip everything into the blender jug in one batch. Keep the milk and ice close by so the next phase flows without pauses. Wash your hands after handling the cherries, since their juice can stain the skin and the board.

Blend until smooth and thick

3. 3Load the blender
   Add the cherries, banana, almonds and grated chocolate to the clear glass blender jug. Pour in the milk and add a generous handful of ice cubes. Place the lid firmly on the jug.
   Look for Ice sits on top of the fruit and milk, with the chocolate curls spread across the surface.
   Tip Add the milk before the ice so the blades catch the liquid and blend more evenly.
4. 4Blend until thick and smooth
   Blend on high until the mixture is smooth, thick and deep brown, with small flecks of cherry still visible. Stop once the ice is fully crushed and the frappe pours slowly.
   Look for The frappe is deep brown, thick and glossy, with small cherry flecks.
   Tip Pause and scrape down the sides once if the ice sticks, then blend again briefly.

After blending, the frappe is smooth, thick and deep brown, with small flecks of cherry visible throughout. It should look glossy and hold together when you lift the spatula, rather than look thin or foamy. Listen for the blender to change pitch as the ice crushes, and stop once the sound smooths out. If the mixture stays chunky, add a splash more milk and blend briefly.

Check the color: a uniform dark brown means the chocolate has blended in fully, while streaks of lighter color mean the blend needs a few more seconds. Scrape down the sides once if pieces cling to the jug, then blend again for a few seconds. Pour a small test spoonful to confirm the texture before you pour the whole batch into the glass.

Pour and garnish the frappe

5. 5Pour and finish the glass
   Pour the frappe into a tall glass and let it settle. Pipe a high swirl of whipped cream on top, then let dark chocolate drip down the sides of the glass for the final presentation.
   Look for The frappe settles with a glossy finish and the cream stands tall on top.
   Tip Chill the glass beforehand so the frappe stays thick while you pipe the cream.
6. 6Serve right away
   Serve the frappe at once with a straw and a spoon for the cream. Stir gently before drinking so the chocolate and cherry flecks blend through the milk and ice.
   Look for The cream holds its shape and the drink is still cold and thick.
   Tip Serve within a few minutes, before the ice melts and the frappe thins.

At the end of this phase, the frappe fills the tall glass with a glossy surface, and the whipped cream stands in a high, even swirl on top. Check that the cream holds its shape and does not slump, which means it is cold and firm enough. The chocolate should run down the outside of the glass in thin lines, like a drip, and the drink should still be cold and thick. Before serving, make sure the glass is steady and the cream is intact, and add a straw and a spoon. Serve immediately, while the ice is still crisp and the cream is firm, so the drink looks as good as it tastes.

Common mistakes

The most common mistake is adding the ice before the milk, which forces the blades to work against dry, hard ice and leaves large pieces behind. Pour the milk in first, then add the ice on top. Another mistake is grating the chocolate too coarsely, which leaves gritty chunks in the frappe; use a fine grater and chill the chocolate briefly for cleaner curls.

Blending for too long also causes problems, because the ice melts and the frappe turns thin and watery. Blend just until smooth and thick, and stop as soon as the color is even. Overfilling the blender jug can stop the blades from circulating the mixture, so leave room at the top. Finally, do not pipe the cream onto a warm glass, because it will soften and slide.

How to tell it’s done

A finished black forest frappe is smooth, thick and deep brown, with the ice fully crushed and small flecks of cherry still visible. The frappe should pour slowly from the blender jug and hold a soft ribbon on the spoon before it settles. There is no set temperature for this drink because it contains no raw protein; it is served cold.

To check the texture, lift a spoonful and look for a glossy, even color with no streaks of white milk or dark ice chunks. If the drink looks too thin, add a few more ice cubes and blend briefly. If it looks too thick to pour, add a splash of milk. The whipped cream should stand high on top and keep its shape for several minutes.
