How to Make It
Process toffee pieces in a food processor until very finely ground, about 30 seconds. Add butter, honey, and salt. Process until blended, about 30 seconds. Transfer butter mixture to a large sheet of plastic wrap, and roll into a 5-inch-long, about 1 1/2-inch-wide log. Chill at least 2 hours or up to 2 weeks.
Whisk together ricotta, milk, and egg yolks in a medium bowl. Sift together flour, baking powder, and salt in a large bowl. Whisk ricotta mixture into flour mixture until combined. Beat egg whites at medium speed with a mixer until stiff peaks form, about 3 minutes. Fold beaten egg whites into ricotta mixture in 2 batches until just combined.
Heat an electric griddle to 375°F or a large stainless steel skillet over medium-low. Lightly grease with butter. Working in batches, spoon 1/3 cup batter per pancake onto griddle. Cook until tops are speckled with bubbles and sides look set, 5 to 6 minutes. Flip and cook until golden brown, 5 to 6 minutes; remove pancakes. Wipe griddle; repeat with remaining batter.
To serve, divide hotcakes into 4 stacks; top each stack of hotcakes with 1/2 cup banana slices, 2 honeycomb butter slices, and 1/4 cup crushed honeycomb toffee.
