This Banana Oat Chocolate Chip Snack Cake is the best!

Every time I make this cake, I hear words like “the best thing I’ve ever eaten”, “unbelievable” and “awesome”.

And I disagree. This easy banana oat snack cake is one of the best things he makes with ripe bananas for destruction.

banana cake batter

This simple one-bowl recipe starts with a super-easy banana cake batter.

Basic Ingredients (Delicious, Deep Flavor – Thanks, Brown Sugar!):

  • butter
  • brown sugar
  • mashed banana
  • egg + vanilla essence
A glass bowl with mashed bananas, eggs, brown sugar and butter.

This batter also gets a boost from the oats in the batter and a dash of cinnamon.

And of course… chocolate chips. 😉

I’ve made this cake with old-fashioned oats and quick oats, and both work well (the halves of each are a good combination, too).

And speaking of variations, cakes using all-purpose flour and whole wheat flour are delicious.

do not mix too much

As with all good cake batter, mix until everything is well blended and free of dry streaks.

Overmixing can kill a light, fluffy cake batter.

yes. Do not overmix. You can move on without talking too much about the lecture. OK?

Amazing Coconut Oats Streusel

One of the things that makes this Banana Oat Snack Cake so special is the simple streusel that adorns the top.

Unique and very delicious.

Coconut oatstroeusel:

  • Old-fashioned oats (quick oats don’t work well with streusel)
  • coconut flakes (sweetened or unsweetened)
  • light brown sugar or dark brown sugar
  • melted butter (I’m a rebel and always use salted butter)

Let’s talk about cake pans

This cake can be baked in an 8X8 or 9X9 inch pan. It fills up with an 8X8 inch pan and bakes pretty high, but the pan we use to bake this cake makes a mile-high fluffy cake exceptional.

You can also bake in a metal or glass skillet.

If using a glass pan, Lower oven temperature by 15 or 25 degrees and watch baking time (cake may need more time in a cooler glass pan).

This cake will likely bake well in a 9-inch circular pan, and double that in a 9X13-inch pan.

Assemble cake in pan with batter, streusel, chocolate chips and baked cake.

really great cake

The crumbs on this cake are flavorful and fluffy, and the streusel is buttery golden and the best part of the crunch.

Of course, it doesn’t hurt to “sprinkle” chocolate chips on top.

This next statement pains me, but I have to say: If you prefer, you can make the cake without the chocolate chips.

{So think twice before committing, right?}

breakfast, snack or dessert

This Banana Oat Snack Cake is perfect for any occasion. Enough bananas for breakfast (cough). Decadent enough for dessert.

And tempting enough for a morning, noon, or evening snack.

I suggest you immediately reserve a few bananas to hang out with until they are properly discovered, then make this cake right away.

Might be the best banana baked goods ever.

banana oats chocolate chip snack cake


  • ½ cup (114 g) softened butter (use salted)
  • ½ cup (106 g) packed light brown sugar or dark brown sugar
  • 1 cup (235 g) Ripe, mashed bananas (about 3 medium bananas)
  • 2 big egg
  • 1 tea spoon vanilla extract
  • 1/3 cup (135 g) Old-fashioned rolled barley (see note)
  • ¾ cup (107 g) all-purpose flour or whole grain
  • 1 tea spoon Baking powder
  • 1 tea spoon ground cinnamon
  • ½ tea spoon baking soda
  • ½ tea spoon salt
  • 1 cup (170 g) chocolate chips


  • ½ cup (50 g) old fashioned rolled barley
  • ½ cup (43 g) sweetened or unsweetened coconut flakes
  • ¼ cup (53 g) stuffed with cane sugar
  • ¼ cup (57 g) Melted butter (use salt)
  • sprinkle chocolate chips
  • Preheat oven to 350 degrees Fahrenheit. Lightly grease the 8X8 or 9X9 inch baking sheet (see note).

  • In a mixing bowl (using a stand mixer with a paddle attachment or a handheld electric mixer), add the butter and brown sugar and beat until light and creamy, 1-2 minutes.

  • Add the mashed bananas, eggs and vanilla and mix well.

  • Add oats, flour, baking powder, cinnamon, baking soda, salt and chocolate chips. Mix until the dry ingredients are just combined and no dry streaks remain (do not overmix).

  • Spread the batter evenly over the prepared frying pan.

  • For streusel, combine the oats, coconut, brown sugar and melted butter in a small bowl and whisk with a fork until smooth.

  • Spread the streusel evenly over the cake and sprinkle with chocolate chips (follow your heart on this one).

  • Bake for 25 to 30 minutes until a toothpick comes out clean or moist crumbs and the top bounces off to a light touch.

Oats: I made this cake with 100% Old Fashioned Oats and Half Old Fashioned Oats/Half Quick Oats. I think 100% Quick Oats are also great for batters. Old-fashioned oats are perfect for getting the best piece-like texture in streusel.
bread: If using a glass pan, lower the oven temperature by 15 or 25 degrees (to keep the dough in the center and not over brown the edges). Be careful with the baking time – if you use a glass pan and lower the oven temperature, you may need to add more baking time. It is necessary to shorten the time.
