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

Before you start

Gather all the ingredients and tools before you start, because the frappe moves quickly from the board to the blender to the glass. Pit and chop the cherries, then slice the banana and keep the slices under a damp paper towel so they do not brown. Toast the almonds in a dry skillet over medium heat for about 3 to 4 minutes, shaking the pan often, until they smell nutty and look golden.

Let them cool, then chop them coarsely. Chill the dark chocolate in the refrigerator for 10 minutes so it grates into clean curls instead of smearing. Measure the milk and ice, and chill the tall glasses in the freezer if you have the time. Set the whipped cream canister and chocolate sauce within reach so you can finish the drink without delay.

Instructions

Fruit, nuts and chocolate ready

1. 1Prepare the fruit and nuts
   Place a wooden board on the counter. Pit and chop the fresh red cherries with a chef's knife. Slice the ripe banana into rounds. Coarsely chop the toasted almonds and set them aside in a small bowl.
   Look for Cherries are roughly chopped into small pieces and the banana rounds are even.
   Tip Chop the cherries just before blending so their juice stays bright and fresh.
2. 2Grate the dark chocolate
   Hold a block of dark chocolate against a fine box grater and grate it over the board. The chocolate falls as fine, curly shavings. Keep a small pinch of shavings aside for the garnish.
   Look for Fine curls of chocolate collect on the board in a soft mound.
   Tip Chill the chocolate for 10 minutes first so it grates cleanly without melting.

At the end of this phase the cherries are chopped into small, even pieces, the banana is sliced into rounds, and the almonds are coarsely chopped and cooled. The dark chocolate has been grated into soft, fine curls that gather on the board.

The fruit should smell fresh and sweet, and the chocolate should look dry and separate rather than oily or clumped. Check that nothing is sitting in warm spots, because the fruit and chocolate should stay cold until they meet the ice in the blender. If the chocolate has softened, return it to the refrigerator for a few minutes before you blend it.

Frappe blended smooth

3. 3Blend the frappe
   Add the banana slices, chopped cherries, grated chocolate, chopped almonds and ice cubes to a clear blender jar. Pour in the milk. Blend on high until the mixture is smooth and thick, stopping once to scrape down the sides.
   Look for The mixture turns smooth, thick and a deep brown with no visible ice or fruit pieces.
   Tip Add the milk last and pulse first, so the ice breaks up before the blender runs at full speed.
4. 4Pour into the glass
   Pour the dark chocolate frappe into a tall glass with a textured base. The drink should look rich and deep brown with a glossy finish. Repeat with a second glass if you are serving two.
   Look for The frappe is glossy, deep brown and holds its body in the glass.
   Tip Chill the glasses in the freezer for 10 minutes for a colder, thicker drink.

At the end of this phase the mixture is smooth, thick and an even deep brown, with no visible pieces of ice, fruit skin or almond chunks. The sound of the blender changes from a rough crunch to a steady, smooth whir, and the mixture pulls away from the sides of the jar in a slow, glossy swirl. Lift the lid and scrape down the sides with a spatula, then blend again for a few seconds if any flecks remain. The frappe should pour slowly and hold its body, neither watery nor stiff. If it is too thick to move, add a splash of milk and blend again briefly before pouring.

Glass topped and served

5. 5Top and garnish
   Pipe a generous swirl of whipped cream from the canister over the top. Drizzle chocolate sauce down the sides of the glass. Finish with a few cherry pieces, the reserved chocolate shavings and the extra almond pieces, then serve immediately.
   Look for The whipped cream sits high and the chocolate sauce runs in streaks down the glass.
   Tip Pipe the cream just before serving so it keeps its shape and does not sink into the frappe.

At the end of this phase the frappe fills the textured glass with a glossy, deep brown body. The whipped cream stands in a generous swirl on top, the chocolate sauce runs in streaks down the sides, and the cherry pieces, almond pieces and chocolate shavings sit neatly on the cream. Check that the cream still holds its shape and the garnish is not sinking. The drink should be cold to the touch and served at once, because the cream softens and the frappe loses its thickness as it stands.

Common mistakes

The most common mistake is blending too long, which heats the mixture and turns the frappe thin and dull instead of thick and glossy. Blend in short bursts and stop as soon as the mixture is smooth. Another error is using warm or soft chocolate, which melts into streaks rather than grating into fine shavings; keep it chilled before you grate.

Adding too much milk at the start also thins the drink, so pour it in gradually and adjust only if the blend is stuck. Skipping the pitting of cherries leaves pits in the glass, which is unpleasant and a choking risk. Finally, piping the whipped cream too early lets it slump into the frappe, so add it only just before the drink goes to the table.

How to tell it’s done

A finished frappe is smooth, thick and an even deep brown with a glossy surface that clings to a spoon. It should pour slowly from the jar and hold its shape for a moment before settling. There are no visible ice shards, fruit pieces or almond chunks, and the banana has fully broken down so the texture feels creamy on the tongue.

Because the drink is made with milk, fruit and chocolate rather than eggs or meat, there is no safe internal temperature to reach; it is ready when the texture is right. Serve it cold, and finish with the cream and garnish immediately so the glass looks as good as it tastes.
