Preheat your oven to 180c/350 F and brush the insides of 4 ramekins with oil. To a bowl, add the melted butter, eggs, and almond milk. Whisk to combine.
Add the almond flour, baking powder, and ¼ tsp salt. Whisk until incorporated. Divide the batter into the 4 ramekins.
Bake the buns for 15 minutes, or until an inserted toothpick comes out dry. Set the ramekins aside and let the buns cool. Meanwhile, start preparing the burger patties.
Add the ground beef to a bowl and add ½ tsp of salt and 1 tsp of black pepper. Mix to incorporate the seasoning. Divide into 4 equal balls.
Add the oil to a skillet and place it over medium-high heat. Press the beef balls slightly until they are the size of the ramekins. Once the oil skillet heats up, add the patties and cook for 2 minutes on each side, or until it’s cooked to your liking. Take the patties off the heat and transfer them to a plate.
To assemble, cut each bun in half crosswise and lay the bottom halves flat on a clean surface. Slice the edges of the cheese slices in a zigzag form to resemble sharp teeth. Slice the cucumber pickle lengthwise into 4 slices.
Spread ½ tbsp of mayonnaise to each slice and top with a piece of lettuce. Add the patties and top with a pickle slice each. Let the pickle slices hang from the edge to resemble a tongue that’s sticking out.
Add the cheese slices and top each one with 1 tbsp of ketchup. Spread the ketchup to the edges to resemble oozing blood. Top with the top half of the bun.
Poke each olive with a toothpick. Secure 2 olives onto each burger to resemble eyes. Serve immediately!
