After lots of testing, tweaking, and more taste tests than we can count, we finally landed on the perfect homemade frosting recipe, and it was so worth it. It’s smooth, fluffy, and just the right amount of sweet, but the best part is how easy it is to customize. once you have this base, turning it into fun flavors like pumpkin spice (or anything else you’re craving) is effortless. A few simple swaps or add ins, and suddenly you’ve got a whole new frosting that tastes bakery level but is still totally doable at home!
This is the Italian Method (not French) — Why?
For this recipe, I use the Italian meringue method rather than the French method—and for good reason. While the Italian method is slightly more technical, it produces a much more stable and less fragile macaron shell, which means more consistent results overall. The French method is quicker, but it’s easier to overmix and can lead to clumps or an unstable batter.
The key difference comes down to how the sugar is incorporated. With the Italian method, a hot sugar syrup is poured into whipped egg whites to create a strong, glossy meringue, which is then folded into the almond flour paste. The French method, on the other hand, involves gradually adding granulated sugar directly into raw egg whites and folding the dry ingredients into the meringue—making the batter more sensitive to overmixing.
Why I Measure in Grams (and You Might Want To, Too)
If you’ve ever made the same recipe twice and gotten two totally different results, the measuring method is often the reason.
Professional bakeries almost always measure by weight, not volume. Measuring cups leave room for inconsistency—especially with ingredients that pack differently depending on how you scoop or pour them. A scale removes all of that guesswork.
One of the biggest offenders is sugar. Different sugars (and even the same sugar measured by different people) can vary wildly in volume, but 100 grams is always 100 grams. Measuring by weight gives you repeatable, bakery-consistent results and cuts down on extra dishes at the same time.
A food scale is one of the best (and most affordable) investments you can make for your kitchen if you love baking and want your recipes to turn out exactly the same every time.

Fluffy Pumpkin Spice Buttercream
Ingredients
- 1/2 cup butter
- 3 cups powdered sugar
- 1/2 cup canned pumpkin drained to ~1/4 cup (60g)
- 1 tsp pumpkin pie spice
- 1 tsp cinnamon
- 1 tbsp heavy cream or milk
- 1 tsp vanilla extract
Method
- Prepare the pumpkin puree. Start by draining your canned pumpkin—line a small bowl with a cheesecloth, scoop in the pumpkin puree, and squeeze out the liquid.
- (Pumpkin holds a lot of moisture, so don’t skip this step or your buttercream may end up too soft to hold its shape!)
- Cream the butter. In a stand mixer (fitted with paddle attachment) (a hand mixer also works!), add butter and beat on medium-high for 3-5 minutes or until butter is smooth and turns a fluffy off-white color.
- Incorporate the powdered sugar. Reduce the mixer speed to low and gradually add the powdered sugar until a thick mixture forms.
- Add pumpkin & spices. Add in the drained pumpkin puree along with the pumpkin pie spice, cinnamon, and a pinch of salt (optional if you used salted butter). Mix on medium speed until the pumpkin is fully blended into the frosting.
- Whip the heavy cream. Pour in the heavy cream and increase the mixer speed to high. Whip the frosting for 2-3 minutes, or until it becomes light, fluffy, and holds soft peaks.
- Frost & enjoy! Use the pumpkin spice buttercream right away to frost cookies, cakes, or cupcakes. If not using immediately, cover the bowl tightly & store it in the refrigerator for up to a week!
