Ingredients

Dry Ingredients

• All-Purpose Flour: 1 1/2 cups (180g)

• Baking Powder: 1 tsp

• Baking Soda: 1/2 tsp

• Ground Cinnamon: 1/2 tsp (optional)

• Salt: 1/4 tsp

Wet Ingredients

• Ripe Bananas: 3 medium (mashed, about 1 cup)

• Unsalted Butter or Neutral Oil: 1/3 cup, melted

• Granulated Sugar or Brown Sugar: 1/2 cup (100g)

• Large Egg: 1, room temperature

• Vanilla Extract: 1 tsp

• Milk: 2 tbsp

Step-by-Step Instructions

Step 1: Prepare Batter Base

1. Preheat your oven to 350°F (175°C). Place a 12-cavity rectangular silicone mold onto a baking sheet for stability.

2. In a large mixing bowl, peel and thoroughly mash the ripe bananas with a fork until smooth.

3. Whisk in melted butter (or oil), sugar, egg, milk, and vanilla extract until well combined.

Step 2: Combine Dry Ingredients

1. Sift the flour, baking powder, baking soda, ground cinnamon, and salt directly into the banana mixture.

2. Stir gently with a spatula or spoon until just combined and no dry flour streaks remain. Do not overmix.

Step 3: Fill Silicone Molds and Bake

1. Spoon equal amounts of batter into each cavity of the silicone mold, filling each about 3/4 full. Smooth the top with the back of the spoon.

2. Bake in the preheated oven at 350°F (175°C) for 18–22 minutes, or until a toothpick inserted into the center of a bar comes out clean.

Step 4: Cool and Serve

1. Remove the mold from the oven and let the bars cool in the silicone cavities for 10 minutes.

2. Gently pop the mini banana bread bars out of the flexible silicone cavities and transfer to a wire rack to cool completely. Serve warm or at room temperature.

Tips & Substitutions

• Baking Sheet Support: Always place flexible silicone molds on a sturdy metal baking sheet before filling with batter to prevent spills during transfer.

• Riper is Better: The spottier and brown the bananas are, the sweeter and more moist your mini bars will be.

• Mix-in Ideas: Fold in 1/2 cup of mini chocolate chips, chopped walnuts, or pecans into the batter right before spooning into molds.

Storage

• Room Temperature: Store cooled banana bars in an airtight container at room temperature for up to 3 days.

• Refrigeration: Store in the fridge for up to 1 week. Warm briefly in the microwave for 10 seconds before eating.

• Freezing: Wrap individual mini bars tightly in plastic wrap and freeze in a ziplock bag for up to 3 months. Thaw at room temperature for a quick grab-and-go snack.

Serving Suggestions

• Spread Topings: Serve warm spread with butter, peanut butter, or nutella.

• Breakfast Pairing: Enjoy alongside a cup of hot coffee, tea, or a glass of milk.

Variations

1. Chocolate Chip Banana Bars: Stir in 1/2 cup of mini dark chocolate chips.

2. Oat & Honey Banana Bars: Swap 1/2 cup of flour with rolled oats and replace sugar with honey.

3. Nutty Crunch Bars: Top each batter-filled cavity with chopped walnuts or sliced almonds before baking.

Frequently Asked Questions

Do I need to grease a silicone mold?

Generally, high-quality food-grade silicone molds do not require greasing. However, a light spritz of non-stick cooking spray ensures effortless release.

Can I bake this recipe in a standard muffin tin?

Yes! If using a standard 12-cup muffin pan, line with paper liners or grease well, and bake at 350°F (175°C) for 18–20 minutes.

Why are my mini banana bread bars dense?

Overmixing the batter develops gluten, which can make the cakes dense. Stir gently just until dry ingredients are incorporated.
