Cook’s Kit
Before you start baking, make sure you have the following tools on hand:
- Mixing bowls – for combining ingredients.
- Whisk – to mix dry ingredients thoroughly.
- Rubber spatula – for folding in the ingredients without deflating the batter.
- Muffin tin – to shape your muffins.

Step-by-Step: Chocolate Banana Crinkle Muffins

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures that your muffins bake evenly.
Step 2: Prepare the Muffin Tin
Line your muffin tin with parchment paper or muffin liners. This will prevent the muffins from sticking and make cleanup a breeze.
Step 3: Mix Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, granulated sugar, cocoa powder, baking soda, baking powder, and a pinch of salt. Make sure everything is well combined and set aside.
Step 4: Combine Wet Ingredients
In a separate large bowl, whisk together the egg, canola oil, sour cream, and vanilla extract until smooth.
Step 5: Incorporate the Bananas
Add the mashed bananas to the wet mixture and mix until fully incorporated.
Step 6: Combine Wet and Dry Mixtures
Gently fold the dry ingredients into the wet mixture using a rubber spatula. Be careful not to overmix; it’s okay if there are a few lumps.
Step 7: Add Chocolate Chips
Fold in the mini chocolate chips until evenly distributed throughout the batter.
Step 8: Fill the Muffin Tin
Scoop the batter into the prepared muffin tin, filling each cup about two-thirds full. Sprinkle a teaspoon of granulated sugar on top of each muffin to create that signature crinkle.
Step 9: Bake
Place the muffin tin in the preheated oven and bake for 18-20 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
Step 10: Cool and Enjoy
Once baked, remove the muffins from the oven and allow them to cool in the pan for about 5 minutes before transferring them to a wire rack to cool completely. Enjoy your delicious Chocolate Banana Crinkle Muffins warm or at room temperature!
