How to Make Banana Oat Vanilla Morning Muffin Squares

Step 1: Prepare the Pan

Preheat your oven to 350°F (175°C).

Line an 8-inch square baking pan with parchment paper or lightly grease it.

Step 2: Mash the Bananas

Place the ripe bananas in a mixing bowl and mash until mostly smooth.

A few small lumps are perfectly fine and add character to the finished bake.

Step 3: Mix the Wet Ingredients

Add:

• Eggs
• Sugar
• Oil
• Milk
• Vanilla extract

Whisk until the mixture becomes smooth and evenly combined.

Step 4: Combine the Dry Ingredients

In a separate bowl, mix:

• Flour
• Rolled oats
• Baking powder
• Salt

Stir to distribute everything evenly.

Step 5: Make the Batter

Gradually add the dry ingredients to the wet mixture.

Stir gently until no dry flour remains.

Avoid overmixing, which can make the squares less tender.

Step 6: Transfer to the Pan

Pour the batter into the prepared baking pan.

Spread evenly using a spatula.

Sprinkle additional rolled oats over the surface if desired.

Step 7: Bake

Bake for approximately 28 to 35 minutes.

The top should be golden brown and a toothpick inserted into the center should come out mostly clean.

Step 8: Cool

Allow the squares to cool in the pan for 10 to 15 minutes.

Transfer to a cooling rack and let cool completely before slicing.

Step 9: Slice and Serve

Cut into squares and enjoy warm or at room temperature.

Expert Tips for Perfect Morning Muffin Squares

Use Very Ripe Bananas

Dark, spotty bananas provide the best sweetness and flavor.

Don’t Overmix

Mix only until the ingredients are combined. Overmixing can develop gluten and create a tougher texture.

Measure Flour Correctly

Spoon flour into measuring cups and level it off rather than scooping directly from the bag.

Line Your Pan

Parchment paper makes removal effortless and ensures clean slices.

Let Them Cool

Cooling allows the crumb to set properly and improves slicing.

Add Oats on Top

A sprinkle of oats before baking creates a beautiful rustic appearance that looks bakery-worthy.

The Secret to Their Soft and Tender Texture

What makes these squares so incredibly soft?

The answer lies in the balance between moisture and structure.

The bananas, milk, eggs, and oil provide abundant moisture, while the flour and oats create enough support to hold everything together.

Because the batter bakes in a single pan instead of individual muffin cups, moisture remains evenly distributed. The center stays exceptionally soft while the edges develop a subtle golden crust.

This contrast between the tender interior and lightly browned exterior is one of the recipe’s greatest strengths.

These versatile breakfast squares can be served in countless ways.
