What are petit fours?
Petit fours (meaning “small oven” in English) are bite-sized desserts from France. When you think of petit fours, you may think of mini glazed layered cakes with jam in the middle, but they can also be in the form of muffins, biscuits, and even savory appetizers. Most petit fours recipes are quite simple to make, but can be finicky because of their small size.
Ingredients in blueberry petit fours
- Salted oat crumble - This deliciously sweet crumble is made from oats, all purpose, flour, brown sugar, salt, and unsalted butter. Sprinkle a little on top of the baked muffins for an extra hit of sweetness. Bonus: any extra crumble would be a delicious decoration on carrot cake (just in case you needed an excuse to bake another deelicious dessert)!
- Blueberries - Fresh are best! Use my tips below if you want to make the muffins with frozen blueberries instead.
- Vanilla or lemon extract - This depends on how much lemon you like in your blueberry muffins. Vanilla extract will ensure they turn out warm and balanced, but lemon zest adds an extra tang. Use what you love!
- Lemon zest - If you’re going to make a fancy blueberry muffin, there has to be plenty of lemon zest! It adds a beautiful brightness and vibrancy to every single bite.
- Cream cheese frosting - The creamy and tangy topping to your fancy muffins.
How to make blueberry muffin petit fours
Trust me - if you’ve baked blueberry muffins before, you can tackle this blueberry muffin petit fours recipe like a seasoned pro. The oat crumble, muffin batter, and cream cheese frosting all come together quite easily:
Step 1: Make the salted oat crumble. Pulse the oats in a food processor to break them up. Next, add them to a bowl of a standing mixer along with the flour, brown sugar, and salt. Mix to combine. Add the butter in chunks and continue mixing until the mixture is thoroughly combined and crumbly. Set aside.
Step 2: Put the dry ingredients together. Whisk the flour, salt, and baking powder together in a bowl.
Step 3: Make the wet mixture. Whisk the water, oil, eggs, and lemon/vanilla extract together in a large bowl. Pulse the sugar and lemon zest together in a food processor, then add to your wet mixture.
Step 4: Make the muffin batter. Add the dry mix to the wet in two parts, mixing until just combined. To finish, gently fold in the blueberries.
Step 5: Bake the muffins. Pour the blueberry muffin batter into each mold. Add a sprinkle of salted crumble on top, then bake until a toothpick inserted in the center comes out clean.
Step 6: Frosting time. While the muffins are baking, make the cream cheese frosting by beating the butter and cream cheese together in a bowl. Slowly mix in the powdered sugar and vanilla paste until the frosting is smooth and fluffy.
Step 7: Decorate and enjoy! Pipe some frosting on top of each cooled muffin and sprinkle more salted crumble on top. Enjoy!
Tips to make the best blueberry petit fours
- You’ll need cylinder baking molds to make this recipe. They always come in handy when you’re craving mini baked goods, like these petit fours or Cherry Chocolate Mini Cakes.
- The baking molds will cause your muffin batter to dome slightly in the oven. For the perfectly symmetrical and classic petit fours look, trim the top with a serrated knife so it’s flat.
- Don’t remove the muffins from the molds too early! Just like a bundt cake, the muffins are likely to collapse if you were to take them out of the molds while they’re still piping hot.
- If you don’t have vanilla paste to use in the frosting, replace it with vanilla extract instead.
Frequently asked questions
What if I don’t have the right baking molds?
Not a problem! Turn these petit fours into simple blueberry muffins by baking the batter in a lined muffin tray instead of the molds.
Can you bake these with frozen blueberries instead?
Yes, but they need to be fully thawed beforehand! When baking blueberry muffins with frozen blueberries, rinse the berries under warm water to thaw and then dry them really well using paper towels. Once they’re dry, you’re good to go!
Can you make these muffins ahead of time?
I don’t recommend making these more than 1 day in advance. They’re so moist and soft when they come out of the oven and leaving them for longer than a few days could dry them out.

Hey there, I just tried your recipe and the silicone mould was filled 3/4 full with a tsp of crumble on top. Although they filed so much that leveling them would have left practically no crumble on top. Is this what happens for you? As in the picture I can also see very little crumble.
Thanks!
Emily
Hi there Brooke! Great questions - when I fill my molds to 3/4 of the way full usually they don't overflow. If yours did - you could always trim off the bottom so that you can preserve thee crumble! Or perhaps reduce the amount of batter in your molds to make up for the amount of oven spring that's happening. As for the crumble, you can certainly add the crumble both onto the top of the muffin or simple to the top of the blueberry muffins after they've been frosted! I tend to add a bit of crumble onto the top of the muffins and touch on top of the cream cheese. Depending on your preference, you can add much more or less!
