A flapjack is a type of sweet baked good, often made with oats and sugar.
You'll usually find flapjacks at British bake sales or cafes. They're like a mix between a granola bar and a cookie - crunchy on the outside, chewy on the inside. Some people also use the term to describe a simple flight maneuver in aviation, where an airplane's wing is moved up and down to create lift. In this case, the word "flap" comes from old-fashioned aircraft controls.
A pancake.
Example: Sven ordered a stack of flapjacks with maple syrup, two strips of bacon, and an egg, sunny side up.
