Biscuit Egg Muffin Recipe: Flaky Crusts With Runny Yolk Centers

This biscuit egg muffin recipe delivers the perfect balance of flaky crusts and runny yolk centers—like a breakfast biscuit and egg in muffin form. The secret lies in combining biscuit dough with beaten eggs, creating a tender, golden shell that holds custardy yolks at the center. I developed this recipe after years of testing different ratios, and it never fails to impress, whether for a quick breakfast or a snack on the go.

The beauty of these muffins is their versatility—you can customize them with cheddar cheese, fresh herbs, or even diced ham for added flavor. The baking time is short, typically 15 to 20 minutes at 375°F, ensuring the yolks stay rich and creamy while the crust achieves that desirable crispness. They’re also perfect for meal prep, holding up well in the fridge for up to 4 days or freezing for future convenience.

What makes this recipe stand out is the simplicity of the technique—no special equipment is needed, just a muffin tin and a few basic ingredients. The flaky texture comes from the biscuit dough, while the eggs provide that satisfying custardy bite. Each muffin is a handheld breakfast solution, perfect for busy mornings or a satisfying snack when paired with a side of jam or gravy.

Once baked, these egg muffins are best enjoyed fresh, but they reheat beautifully in the oven or microwave. The combination of textures—crispy crust, tender egg, and any added toppings—makes them a standout dish in any breakfast lineup. Let’s get started on creating your own batch!

Ingredients for biscuit egg muffin

Twelve simple ingredients transform into golden, flaky egg muffins with custardy centers—breakfast magic in minutes.

The butter and flour are your golden ticket for that perfect flaky crust. Use cold butter—cut it into small cubes so it distributes evenly in the dough. King Arthur or Gold Medal flour works best for flakiness, but any all-purpose will do. I grab mine from Whole Foods or the bulk section at Kroger—just make sure it's fresh. The baking powder needs to be fresh too; if it's over a year old, toss it. For the eggs, room temperature is key—they'll blend smoother into the dough. Pro tip: beat them first so you're not scrambling mid-muffin-making.

No cheddar? Swiss or Colby Jack work just as well—just shred it yourself. Fresh herbs like chives or parsley add brightness, but dried herbs at half the amount are fine in a pinch. Short on milk? Heavy cream or half-and-half gives extra richness, but whole milk keeps it classic. The custardy centers are all about the eggs—extra large eggs yield the most satisfying runny yolks. If you're worried about overmixing, stop as soon as the dough comes together. It's okay if it looks shaggy—those flaky layers come from the butter, not the mixing.

These muffins are best enjoyed fresh, but they reheat beautifully—10 seconds in the microwave or 5 minutes at 350°F in the oven. Store leftovers in an airtight container in the fridge for 4 days or freeze for 3 months. I like to freeze them in a single layer first, then transfer to a bag—prevents freezer burn. For meal prep, bake a double batch and freeze half. They're perfect for grab-and-go breakfasts or a quick snack when paired with hot sauce or jam. Trust me, the first bite is worth the effort.

Step-by-step instructions for flaky biscuit egg muffins

Here's how to create golden, flaky biscuit cups with perfectly runny yolk centers—every time!

Preheat your oven to 375°F while you prepare the dough. In a large bowl, combine the 2 cups All-Purpose Flour, 1 tbsp Baking Powder, and 1 tsp Diamond Crystal Kosher Salt. Whisk just until blended—don't overmix or you'll develop gluten and lose that tender texture.

Next, add the 0.75 cup Cold Unsalted Butter cut into small cubes. Using a pastry cutter or your fingers, work the butter into the flour mixture until you have pea-sized crumbs with some larger butter pieces remaining. The cold butter creates steam pockets when baked, which gives those beautiful flaky layers. I like to press down gently on the mixture—this ensures even distribution without melting the butter too soon.

Add the 4 whole Large Eggs and 0.5 cup Whole Milk to the bowl. Mix with a wooden spoon just until the dough comes together. The dough should be shaggy and slightly sticky—this is perfect for our egg muffins. If it feels too dry, add 1 teaspoon more milk; if too wet, sprinkle in 1 tablespoon more flour.

Lightly grease a standard 12-cup muffin tin with 1 tbsp Vegetable Oil, making sure to coat each cup thoroughly. This prevents sticking and makes removal easy. Using a 2-tablespoon scoop, divide the dough into 12 equal portions and gently press each one into a muffin cup, forming a thin crust about ¼-inch thick.

Here's the thing—don't overpress the dough or you'll lose that flaky texture. I like to use the back of a spoon to gently press the dough into the corners of each cup. The edges should be slightly thicker than the center—this creates that perfect rise. Once all cups are filled, sprinkle each with a pinch of the 0.5 tsp Ground Black Pepper and 1 cup Sharp Cheddar Cheese (if using).

Bake the biscuit cups for 12-14 minutes until they're golden brown at the edges and feel firm to the touch. You'll see the centers puff up slightly—this is when you know they're ready. Remove from the oven and let them cool in the tin for 5 minutes before carefully transferring to a wire rack. This brief cooling prevents them from breaking when you add the egg mixture later.

While the biscuit cups cool, whisk together the 6 whole Extra Large Eggs in a medium bowl until just combined—no need to overbeat. The eggs should be fully incorporated but still slightly lumpy. Stir in the 0.25 cup Fresh Chives (if using) and 0.5 tsp Ground Black Pepper.

This is where the magic happens: the ratio of eggs to biscuit cups is crucial. Six eggs for 12 cups gives you that perfect custardy center without making the muffins soggy. I always use room-temperature eggs—they whip up more evenly and create a smoother texture. If you're worried about overfilling, don't be. The biscuit cups will hold their shape while the eggs cook through.

Preheat your oven to 350°F while you prepare the egg mixture. Using a small ladle or spoon, carefully divide the egg mixture evenly among the 12 cooled biscuit cups. Fill each cup about ¾ full—this gives room for the eggs to rise while keeping the centers runny.

Place the filled muffin tin in the preheated oven and bake for 18-20 minutes. You're looking for muffins with golden tops and edges that pull away slightly from the tin. The centers should still be slightly jiggly when you remove them—this indicates that perfect runny yolk. Here's the secret: don't overbake. The muffins will continue cooking slightly as they cool, and you want that yolk to remain liquidy in the center.

Let the muffins rest in the tin for 2 minutes before carefully removing them to a wire rack. Serve immediately while still warm—each bite delivers that flaky, buttery crust with a rich, custardy egg center. These make an incredible breakfast or brunch dish, and they reheat beautifully in the microwave for 15-20 seconds if needed.
