Whenever I shop at Costco, I have to make sure to avoid certain aisles. The ice cream aisle, the cheese aisle and most importantly, the baked goods aisle are the three most dangerous places. The smell of freshly baked baguettes, croissants, cakes, and muffins is just too tempting. I love many of their products, but Costco's muffins might rank in the top five of my all-time favorite items. The muffins are the size of your fist and chock full of chocolate, blueberries, poppy seeds, you name it, they make it. The only problem is that you just can't buy one, you have to buy all 12! So in order to satisfy my muffin craving without having to loosen the belt too much, I decided to make my own. I had to make these muffins special enough to make me forget about Costco's version, or at least temporarily. What can be better than a little browned butter, banana and raspberry all jammed into one? Here are caramelized banana raspberry swirl muffins that, dare I say, compete with Costco's muffins.
Caramelized Banana Raspberry Swirl Muffins
- ⅓ cup butter
- 3 medium bananas peeled, cut in half lengthwise
- 1 large egg
- 1 teaspoon vanilla extract
- ¼ cup Greek yogurt
- ⅔ cup brown sugar
- 1 teaspoon cinnamon
- 1 ½ cups all-purpose flour
- 1 teaspoon baking powder
- 1 teaspoon baking soda
- ½ teaspoon salt
- 1 cup raspberries
- ¼ cup raspberry jam
- Preheat oven to 350 degrees F.
- Melt ⅓ cup in a nonstick pan over medium-low heat. Continue to cook until the butter begins to brown and smells nutty, about 4-5 minutes. Remove from heat and pour into a medium bowl.
- In the same pan, melt 1 tablespoon butter. Spread the halved bananas in one even layer in the pan and cook until browned and caramelized, about 2 minutes. Flip the bananas over and brown on the other side, another 2 minutes. Remove from heat and gently mash the bananas. Add the bananas to the browned butter and let cool.
- Add 1 egg, 1 teaspoon vanilla, and ¼ cup Greek yogurt to the banana mixture, beating until well combined.
- In a large bowl, combine the dry ingredients including ⅔ cup brown sugar, 1 teaspoon cinnamon, 1 1 /2 cups flour, 1 teaspoon baking powder, 1 teaspoon baking soda, and ½ teaspoon salt. Add the banana mixture, stirring just until combined. Gently fold in 1 cup raspberries.
- Line a muffin pan with liners. Fill each cup ¾ full with the muffin batter. Top each with 1 teaspoon raspberry jam and use a paring knife to swirl in the jam. Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. Let cool on a wire rack.
**Helpful tips and common mistakes
The great thing about these caramelized banana raspberry swirl muffins is that you don't have to wait a full week for the bananas to turn black. In fact, it's actually better if the bananas are not so ripe or they will be very difficult to caramelize.
Caramelizing the bananas before adding them to the muffin mix will help bring out the sugars and add sweetness to the muffins. Let the bananas and brown butter cool before mixing it with the egg. If you add the egg immediately, it might just cook!
Add the wet ingredients together then the dry ingredients in another bowl. Why can't you just throw everything together from the start? Because once you add the banana mixture to the flour mix, you want to stir just enough to combine. If you overbeat the batter, the muffins will become tough. I recommend stirring everything by hand so you have more control over how much to mix.
Once the batter looks like it's mixed, gently fold in the raspberries, trying not to pop them. Fill the muffin cups about ¾ full and top each muffin with 1 teaspoon raspberry jam. Since the batter is a little thick, it's easiest to swirl in the jam with a paring knife.
Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. Your house will smell heavenly, I guarantee it.
These caramelized banana raspberry swirl muffins were insanely delicious. The Greek yogurt and banana make the muffins oh so moist while the tart raspberries and raspberry jam add the flavors. Costco muffins? What Costco muffins?
