Cookie Dough Stuffed Banana Bread

There are banana bread recipes, and then there are the ones that make people stop mid-slice to ask what is inside. This Cookie Dough Stuffed Banana Bread is the second kind. A full layer of soft, gooey cookie dough presses into a loaf pan, chills until firm, and then gets sandwiched between two pours of banana bread batter before baking.

Every single slice contains a defined stripe of cookie dough running through the center, surrounded by moist, deeply banana-flavored bread. Coconut sugar goes into both layers for a caramel warmth that ties everything together, and dark chocolate chips fold into both the cookie dough and the banana bread batter for chocolate in every component of every slice.

What is Cookie Dough Stuffed Banana Bread?

Cookie Dough Stuffed Banana Bread is a banana bread loaf with a full layer of chilled cookie dough pressed into a separate pan, then lifted and placed between two layers of banana bread batter before baking. The cookie dough bakes into a soft, gooey center layer that appears as a distinct stripe in every slice. This recipe uses coconut sugar and gluten free flour in both the cookie dough and the banana bread batter natively.

Ingredients

Cookie dough layer

4 tbsp butter, melted

½ cup coconut sugar or light brown sugar

1 large egg

1 cup gluten free flour

¼ tsp baking soda

½ cup dark chocolate chips

Banana bread batter

4 medium ripe bananas, mashed

1 stick butter, melted

1 cup coconut sugar or granulated sugar

2 large eggs

1 tsp vanilla extract

1 ¾ cups gluten free flour

½ tsp sea salt

1 tsp baking soda

1 cup dark chocolate chips

Key Ingredient Notes

Coconut sugar goes into both the cookie dough and the banana bread batter. In the cookie dough, it adds caramel and molasses depth. In the batter, it pairs with the ripe banana and dark chocolate chips. Light brown sugar substitutes at 1:1 in both.

Gluten free flour goes into both layers, making the whole loaf GF from start to finish. All-purpose flour substitutes at the same amounts if preferred. Half a cup of dark chocolate chips folds into the cookie dough and one full cup folds into the banana bread batter, so every slice contains dark chocolate regardless of where the cookie dough stripe falls.

Four ripe, heavily spotted bananas are essential. An underripe banana produces a flat flavor that disappears against the richness of the embedded cookie dough layer.

How to make Cookie Dough Stuffed Banana Bread, step by step

First, make your cookie dough. In a mixing bowl, combine the melted butter and coconut sugar. Stir together.

Then, add in the egg and stir.

Fold in the gluten free flour and baking soda. Stir to combine.

Fold in the dark chocolate chips. Line a bread loaf pan with parchment paper. Press the cookie dough into the lined pan. Refrigerate for 1 hour.

After that, preheat your oven to 350 degrees Fahrenheit. Line a different standard bread pan with parchment paper.

In a large mixing bowl, add the mashed bananas, melted butter, coconut sugar, vanilla, and eggs. Stir to combine.

Then, add in the gluten free flour, baking soda, and sea salt. Stir to combine.

Then, fold in the chocolate chips. Remove the cookie dough layer from the fridge.

Pour half this mixture into your lined pan. Then, carefully place the cookie dough layer on top. Top with the remaining bread batter. Bake for 60 to 70 minutes, or until a toothpick inserted comes out with only a few moist crumbs.

Finally, remove from the oven. Cool fully before slicing.

Why the Separate Pan Slab Technique Works Better

Most cookie dough banana bread recipes chill the cookie dough directly in the baking pan, then pour batter on top without removing it first. The problem is that the dough layer never fully detaches from the pan, making it difficult to pour batter underneath before placing the dough.

The separate pan technique solves this by chilling the cookie dough in its own pan and then lifting the entire slab out using the parchment paper.

The result is a precisely shaped, fully detached layer that fits exactly into the loaf pan, sits flat between the two batter pours, and produces an even, consistent cookie dough stripe in every single slice.

Helpful Tips

Make the cookie dough a day ahead or use store-bought

The dough chills in the refrigerator for up to 24 hours before assembly. Store-bought refrigerated cookie dough pressed into the same bread pan shape and chilled until firm works as a direct substitute. Any flavor works and cuts 15 minutes of prep without affecting the finished loaf.

Test the toothpick in the banana bread, not the cookie dough

A toothpick inserted directly through the cookie dough layer always pulls out with dough on it regardless of whether the banana bread itself is done. Insert the toothpick into the batter area beside or above the cookie dough layer for an accurate done reading.

Do not overbake

A few moist crumbs on the toothpick at 60 minutes is the correct done signal. The cookie dough layer stays intentionally soft and slightly gooey in the center even when the banana bread is fully baked. Baking past 70 minutes produces a drier banana bread without improving the cookie dough layer.
