It’s not overly sweet. It’s not heavy. It’s that perfect in-between bake — wholesome enough for breakfast, soft enough for afternoon coffee, and satisfying enough that you’ll sneak a second slice without even thinking about it.

  • 1/4 cup chopped walnuts or pecans
  • 1/4 cup dark chocolate chips

How to Make Soft Cinnamon Banana Oat and Almond Flour Breakfast Cake Slice

Step 1: Preheat

Preheat oven to 350°F (175°C). Line or grease an 8×8-inch baking pan.

Step 2: Mash and Mix Wet Ingredients

In a large bowl, mash the bananas until smooth and creamy. Whisk in Greek yogurt, honey (or maple syrup), eggs, and vanilla until well combined.

You’ll already smell that banana sweetness coming through — that’s how you know it’s going to be good.

Step 3: Add Dry Ingredients

Stir in oat flour, almond flour, cinnamon, baking powder, and salt. Mix until just combined. Do not overmix.

Fold in optional nuts or chocolate chips if using.

Step 4: Bake

Pour batter into prepared pan and smooth the top. Bake for 28–35 minutes, or until the center is set and a toothpick comes out clean.

The top should be lightly golden and slightly springy.

Step 5: Cool & Slice

Allow to cool for 10–15 minutes before slicing into squares.

What to Serve With This Breakfast Cake

  • A dollop of Greek yogurt
  • Fresh berries
  • Warm almond butter drizzle
  • Hot coffee or chai
  • Cold milk for the kids

Tips for Perfect Texture

  • Use very ripe bananas for natural sweetness.
  • Let the cake cool before slicing for clean edges.
  • Don’t overbake — it should stay soft.
  • Store covered to retain moisture.
  • For a fluffier texture, sift almond flour before adding.
