Banana Coffee Cake Muffins With Oat Streusel and Icing

My neighbor dropped off four bananas that were past saving for eating, so I mashed them into muffin batter and hid a cinnamon sugar stripe in the middle. That stripe is the whole trick. People bite in expecting plain banana bread and get a soft hit of cinnamon instead.

The topping here is oats, flour, sugar and spice, not the sandy crumble you might expect on a coffee cake. It stays a little dry and crisp, which is what you want against a soft banana crumb. If you'd rather have a classic crumble, swap the oats for more flour, but the oat version is the one I keep making.

You'll need 12 muffin liners and about 45 minutes from start to last drizzle. Three ripe bananas, one bowl of dry, one of wet, and a small bowl of cinnamon paste. That's the whole job.

Step-by-Step Instructions

1. Heat the oven and line the tin

Set the oven to 375°F (190°C) and put paper liners in all 12 cups of a muffin tin. Mixing goes fast once you start, so have the tin ready.

2. Whisk the dry ingredients

In a large bowl, whisk the flour, granulated sugar, baking powder, baking soda, salt, cinnamon and nutmeg until no streaks remain.

3. Whisk the wet ingredients

In a medium bowl, whisk the melted plant butter, eggs, oat milk and vanilla until smooth and slightly frothy.

4. Combine and add the bananas

Pour the wet mix into the dry and whisk just until you can't see dry flour. Switch to a rubber spatula and fold in the mashed bananas. Stop as soon as they're mixed in.

5. Stir the cinnamon sugar paste

In a small bowl, mix the cinnamon, sugar and melted plant butter until it forms a thick, spreadable paste. It will look like wet sand at first, then come together.

6. Make the streusel

In a medium bowl, stir the oats, flour, sugar, cinnamon and nutmeg together, then add the melted plant butter. Mix with a spatula until clumps form. The mixture should still look a bit dry.

7. Layer the batter and filling

Scoop batter into the liners so each is a little less than half full. Drop a small spoonful of cinnamon paste into the center of each, then add more batter until the cups are about three-quarters full. Spoon the streusel evenly over the tops.

8. Bake until golden

Bake for 20 to 25 minutes, until the tops are golden and a toothpick inserted off-center comes out clean. Start checking at 20 minutes.

9. Cool the muffins

Take the tin out of the oven and leave the muffins to cool for 30 minutes. Move them to a rack after the first few minutes so the bottoms don't get damp.

10. Mix the icing

While they cool, whisk the powdered sugar with the plant cream. You want it loose enough to drizzle but thick enough to hold a line. Add more cream or more sugar until it gets there.

11. Drizzle and serve

Zigzag the icing over the cooled muffins with a spoon. Let it set for a few minutes, then eat.

Variations

Chocolate version

add 1/2 cup chocolate chips to the batter and skip the cinnamon paste.

Nut streusel

swap 1/4 cup of the oats for chopped pecans or walnuts.

No plant cream

use any milk or a spoon of water in the icing. Add it drop by drop.

Mini muffins

bake in a mini tin and start checking at 12 minutes.
