Combine honey, cocoa powder, and espresso powder in a small saucepan over medium-low heat. Cook and stir until cocoa and espresso are dissolved and mixture is smooth, 3 to 5 minutes. Remove from heat. Let cool, 10 to 15 minutes.
Preheat oven to 300 degrees F (150 degrees C). Line a baking sheet with parchment paper.
Beat egg whites in a glass, metal, or ceramic bowl until peaks start to form. Add sugar gradually, continuing to beat until a thick and glossy meringue is formed.
Place almonds in a food processor; grind in short bursts until a fine meal forms.
Stir almond meal, coconut, matzo cake meal, and vanilla bean paste into the cooled espresso mixture. Fold in 1/3 of the egg whites at a time until well mixed.
Spoon out about 1 tablespoon of the dough and roll into a ball. Place on the prepared baking sheet. Repeat with the remaining dough, placing macaroon balls about 1 inch apart. Press an espresso bean onto each macaroon.
Bake in the preheated oven until firm, 15 to 20 minutes. Remove macaroons using a spatula; transfer to a rack to cool for 20 to 30 minutes. Place macaroons in an airtight container; let rest until set, 4 to 6 hours.
