My friends have started calling me the pumpkin queen these days. Because I've been sharing all these pumpkin recipes like pumpkin spice latte cake, pumpkin spice cake, with cream cheese frosting or pumpkin cream cake.
About these muffins
This is a simple and easy oil-based recipe with brown sugar that makes a light and airy muffin. The pumpkin puree and spice mix add that wonderful fall flavor.
It takes just 10 minutes to mix and 20 minutes to bake which means you can have these for breakfast in just 30 minutes.

Ingredients and substitutes
- All-purpose flour - plain flour is all you need. If you have to use self-raising flour reduce the baking powder by half.
- Cooking oil - I prefer to use canola or grapeseed oil that is natural and flavorless. The oil keeps the muffins light and airy.
- Light Brown Sugar - I like the flavor molasses brings to the muffins. As a substitute, you can also use regular white sugar and a tablespoon of molasses. Do not use dark brown sugar as the flavor of extra molasses overpowers the pumpkin spice.
- Buttermilk - You can make buttermilk in five minutes at home so there is no need to substitute.
- Pumpkin puree - I'm using homemade pumpkin puree but canned works too
- Pumpkin spice -I'm using homemade but store-bought work too.
- Vanilla Extract - A good quality vanilla extract goes a long way.

Step by step instructions
- Preheat the oven at 170C / 340 F.
- Line a muffin tin with cupcake liners.
Streusel
- In a bowl combine the oats, flour, sugar, salt, and chilled cubed butter
- Rub between your fingers or a pastry blender until you have a crumbly texture.Tip - you can also use a food processor and pulse it all for just a few seconds
- Place it in the fridge to keep it chilled while you prepare the batter.
Muffins
- In a bowl, combine flour, baking powder, baking soda, salt, and pumpkin spice - set aside.
- In the bowl of a stand mixer with a whisk attachment whip the eggs with the sugar until light and foamy
- Add the pumpkin puree, buttermilk, and vanilla extract
- Finally, add the flour mixture and combine well.
- Divide the batter between the muffin liners and top with the chilled streusel
- Bake on the middle rack for 18 to 20 minutes or until a skewer inserted comes clean.
- Cool on a wire rack for 10 minutes before serving.
Frequently asked questions

I like to store them in an airtight container with paper hand towels below and above. The paper towels protect them from drying out.
Yes, muffins are delicious when served warm. I like to wrap the muffin in a moist paper hand towel and heat in the microwave for a quick 30 seconds each. The moisture in the paper towel helps keep the muffin moist.
