Cheesy Cheddar Jalapeño Muffins

Meet Your New Favourite: Cheesy Cheddar Jalapeño Muffins

If you’re craving something savoury, super cheesy, and with a cheeky little kick—meet your new best breakfast (or lunchbox) friend: Cheesy Cheddar Jalapeño Muffins. Think fluffy muffins packed with sharp cheddar, a diced jalapeño pepper stirred right into the batter, plus a sliced jalapeño pepper perched on top like a crown. Perfect to fight that 4PM slump! 

Whether you’re prepping for a brunch, hauling snacks to work, organising drinks at home or just looking for something yum to brighten your day, these muffins deliver. And yes, they’re easy. 

How to Make Cheesy Cheddar Jalapeño Muffins

These muffins come together in no time! You’ll mix your dry ingredients and cheese in one bowl, and your wet ingredients, milk, eggs, grated zucchini, onion, and diced jalapeño in another. Combine the two, scoop into your muffin tin, and top each one with extra cheese and a jalapeño slice for a gorgeous look and extra kick.

Bake until golden and puffed (about 15 minutes), then let them cool slightly before diving in. Warm, cheesy, and just the right amount of spice.

Tips for making the best savoury muffins

  • If you’re using store-bought muffin liners, give them a quick spray of nonstick or grease the tin: some liners like to stick.
  • These muffins freeze beautifully. Once cooled, stash in a ziploc or airtight container and freeze for up to 3 months. Thaw at room temp or warm gently. 
  • Want more heat? Keep an extra jalapeño in the fridge, finely chop it, and toss a little into the batter. Want less heat? Remove the seeds from the diced jalapeño.
  • These are perfect as a grab-and-go snack, or served alongside soup or salad for a cozy meal.
  • Feel free to play around with your cheese game: mix sharp cheddar + smoked cheddar, or add a little parmesan for depth. You do you!

Can you freeze these muffins?

Absolutely! I would recommend freezing your baked muffins and place them in a ziplock freezer-safe bag. These stay fresh for up to 3 months in the freezer and you can basically defrost and bake them on demand! Thaw your muffin, lightly sprinkle it with water and quickly reheat it in a hot oven for 5-10 minutes. 

Baking time and oven temperature

Baking time and oven temperature may vary depending on the oven you are using.  All oven temperatures in my recipes are based on a conventional oven. If you bake with a fan assisted oven, turn down the temperature slightly as these ovens tend to become hotter than a conventional oven at that temperature setting. Ovens have the tendency to deviate from the temperature you set the oven to. I would highly recommend using an oven thermometer to ensure the inside of your oven is at the right temperature. 

An oven that is too hot may result in an overbaked or burnt bake and an oven that is too cold may result in underbaked and soggy bakes. Having the thermometer will not only help in getting the right temperature but also helps in determining the right baking time. 

Enjoy loves!

Yield:

7

Portions

Ingredients

  • 300 g all-purpose flour 
  • 180 g grated sharp cheddar + 20gr extra
  • 250 g grated zucchini (with the skin)
  • 40 g finely chopped white onion 
  • 220 g full-fat milk 
  • 2 large eggs 
  • 1 jalapeño pepper (diced)
  • 1 jalapeño pepper (sliced)
  • 4 tsp (≈ 15 g) baking powder 
  • ¼ tsp ground black pepper
  • ½ tsp salt

Instructions

  1. Preheat your oven to 210 °C and line a muffin tin with liners.
  2. In a large bowl, combine the flour, baking powder, salt, and pepper. Stir in the grated cheddar until it’s all coated.
  3. In a separate medium bowl, mix the grated zucchini, chopped onion, milk, eggs, and the diced jalapeño pepper (yes, that’s your spicy surprise!) until well combined.
  4. Pour the wet mixture into the dry mixture and stir just until combined — don’t overmix (you want these muffins to be fluffy and not tough!). 
  5. Divide the batter into your muffin cups (about 2 ice cream scoops per muffin cup is perfect). Then add some extra cheddar on top and place one slice of jalapeño pepper on top of each muffin before baking
  6. Bake for about 13-17 minutes, until they’re lightly golden and spring back when gently poked. 
  7. Remove them from the oven and let them cool on a wire rack for a bit before digging in. Serve warm or at room temperature. Leftovers? Store in an airtight container at room temp — to refresh: pop them in the toaster or microwave for ~10 seconds.
