This Single-Serve Baked Oatmeal started as a pantry-clean-out experiment and turned into a daily morning favorite. Imagine waking up to a warm, individual ramekin that tastes like a freshly baked berry muffin, but takes just 2 minutes to blend and 15 minutes to bake (or 90 seconds in the microwave!). It is the ultimate "busy morning" breakfast: high-protein, fiber-rich, naturally sweetened, and portioned perfectly for one.
What makes blended baked oatmeal such a viral sensation is the transformation of texture. When rolled oats are quick-blended with milk, a banana, an egg, and a touch of maple syrup, the coarse oat grains turn into a smooth batter. As it bakes, it rises into a tender, cake-like soufflé with a soft center and golden top. Studded with juicy fresh berries or dark chocolate chips, it completely eliminates the gummy, gluey texture that turns so many people away from traditional stovetop oatmeal.
I used to skip breakfast on hectic weekday mornings because making a full pot of oats felt like too much effort for just myself. Discovering single-serve mug baking changed everything. Now, while my morning coffee brews, I toss oats and a banana into a small blender, pour it into a oven-safe ramekin, and pop it into the air fryer or oven. By the time I finish getting ready, breakfast is hot, cakey, and waiting for me. It keeps me energized straight through until lunch!
What Is Single-Serve Baked Oatmeal?
Baked oatmeal is an Amish-origin breakfast tradition where oats are baked with milk, eggs, and spices to create a casserole-like texture similar to bread pudding. While traditional recipes bake a large 9x13 pan designed for large families, single-serve baked oatmeal scales the recipe down to a single 6 to 8-ounce ramekin or mug.
Popularized by TikTok and Pinterest's wellness community, the single-serve technique frequently uses a blender to pulverize whole oats into fresh oat flour. This technique creates a delicate cake texture while preserving 100% of the complex carbohydrates, beta-glucan soluble fiber, and gut-health benefits of whole oats.
It is currently the #1 breakfast trend on Pinterest because it satisfies morning cake cravings in a healthy, refined-sugar-free way that can be customized every single morning with different fruit, nut, and protein toppings.

Key Ingredients
Rolled Oats
Old-fashioned rolled oats blend into a light, fluffy oat flour. Certified gluten-free oats work identically if gluten-sensitive.
Ripe Banana or Applesauce
Half a spotty ripe banana adds natural moisture and sweetness. Swap for ¼ cup unsweetened applesauce for a banana-free version!
Egg or Flax Egg
One egg binds the batter and creates that fluffy, cakey rise. Swap with 1 tbsp ground flaxseed + 3 tbsp water for a vegan option.
Berries & Maple Syrup
Fresh blueberries or raspberries burst into warm jam pockets as it bakes. Top with pure maple syrup and toasted almonds.
Step-by-Step Instructions
Blend Ingredients Smooth
Preheat your oven or air fryer to 350°F (175°C). Lightly grease a 6 to 8-ounce oven-safe ramekin. In a small bullet blender, combine ½ cup rolled oats, ½ ripe banana, 1 egg, 3 tbsp milk, 1 tsp maple syrup, ½ tsp baking powder, a dash of cinnamon, and a pinch of salt. Blend on high for 20 seconds until smooth.
💡 Pro Tip: Don't over-blend! 20 seconds is enough to break down oats into a batter without heating up the mixture.
Fold in Mix-ins
Pour the smooth batter into your greased ramekin. Gently fold in 2 tablespoons of fresh blueberries, raspberries, or dark chocolate chips using a spoon, reserving a few to press into the top.
Bake or Air Fry
Bake at 350°F for 14 to 16 minutes in an oven (or 12 minutes in an air fryer) until the center is set and the top springs back when lightly touched. (Microwave method: Cook on HIGH for 90 seconds).
💡 Pro Tip: For a lava-cake center, remove 2 minutes early! The residual heat will keep the center soft and gooey.
Cool & Top
Let cool for 2 minutes. Top with a dollop of Greek yogurt or almond butter, extra fresh berries, toasted sliced almonds, and a drizzle of warm maple syrup.
Dig In & Enjoy!
Grab a spoon and dig right into the warm, cakey center. Enjoy your nourishing single-serve breakfast!

Expert Tips for the Best Results
Use Spotty Ripe Bananas. The sweeter and spottier your banana, the sweeter your baked oatmeal will be without adding extra sugar.
Add Protein Powder. Boost protein by adding 1 scoop of vanilla or chocolate protein powder to the blender. Add 1 extra tablespoon of milk so the batter doesn't dry out.
No Blender? No Problem! If you don't have a blender, use quick oats or pre-ground oat flour and mash the banana thoroughly with a fork. It will be slightly chunkier but still delicious!
Air Fryer Shortcut. Air frying at 350°F for 12 minutes cuts bake time down significantly compared to waiting for a large oven to preheat.
Chocolate Peanut Butter Twist. Add 1 tbsp peanut butter and 1 tbsp cocoa powder to the blender for a chocolate peanut butter cake breakfast!
How to Store & Meal Prep
🧊 Refrigerator
Bake multiple individual ramekins on Sunday. Cover tightly with foil and refrigerate for up to 5 days. Grab and go in the morning!
