This is a simple alternative to store-bought butter + oil spreads.
You will need a stand mixer, spatula, measuring cup, and measuring spoon.
Allow the butter to sit a room temperature until softened, about 2 hours.
Add butter, oil and salt to the bowl of a stand mixer.
Using the paddle attachment, mix on low speed until butter breaks up and starts to mix with oil, approximately 2 minutes.
Turn the speed up to medium high and mix until mostly incorporated, approximately 2 additional minutes. You may need to stop it occasionally to scrape down the sides with the spatula. There will likely be some small bits of butter left which is fine. The butter will still spread nicely.
Store in an airtight container in the fridge and use as needed.
Other oils can be used such as olive oil. Canola oil was chosen here as it's flavor is very light allowing the taste of the butter to come through.
