Line a 7x11 pan with parchment paper. Whisk together eggs, cream, salt, and pepper. Pour into prepared pan and bake until eggs are set, about 15 minutes.
While the eggs are baking, brown up the breakfast sausage over medium heat until cooked through, breaking up into small pieces as the sausage cooks. Drain off any excess grease.
When the eggs are finished baking, carefully remove from the pan, using the sides of the parchment paper as handles.
Place the bottom of the slider buns into the dish the eggs baked in. Place the baked eggs on the slider buns, removing the parchment paper. Trim off any excess eggs if needed. Top with the crumbled sausage and then top with the sliced cheese, overlapping the cheese slightly. Top with the slider bun tops.
Whisk together the maple syrup and butter and then brush over the slider tops.
Bake for 20 minutes, or until the cheese is melted and the buns are slightly toasted.
Notes
Most packages of sliders will fit perfectly into a 7x11 pan.
If you do not like the texture of baked eggs, cook the egg mixture on low heat, cooking and scrambling the eggs until they reach a soft set scrambled egg.
Breakfast Sliders are best served warm, but can be held at room temperature for up to 2 hours. After that, refrigerate for up to 3 days and toast in the oven until warm to reheat.
Make Ahead: Assemble the sliders, stopping just before the maple butter. Cover tightly and refrigerate for up to 24 hours. When ready to bake, let sit out for 30 minutes, then remove the cover, brush on the maple butter, and bake as directed.
