Not sure if this is what you are looking for, I always called it faux whipped cream or "flour frosting."
Here is my recipe.....
Nonna's Faux Whipped Cream (aka Flour Frosting) - makes enough for one 9-inch layer or 1 doz cupcakes
1c milk
5TB all-purpose flour
2 tsp pure vanilla extract
1/2 pound room temp butter (2 sticks)
1 1/4 cups granulated sugar (DO NOT use powdered/confectioner's sugar, it contains cornstarch)
In a medium saucepan, whisk milk with all of flour.
Heat mixture over medium heat, whisking constantly until the mixture begins to sputter.
Continue stirring while mixture thickens. After about 7 minutes of heating and whisking, it should be thick like cake batter.
Stir in the vanilla extract and set mixture aside until COMPLETELY cool.
In the bowl of a stand mixer with the whisk attachment, set at medium-high speed, beat the softened butter with the granulated sugar until mixture is light, fluffy, not gritty, and white in color (about 3 minutes - longer if using a hand held mixer).. Sugar should be totally incorporated.
When milk/flour mixture is completely cooled, add it to the butter/sugar mixture.
Beat everything for about 1 minute on high speed, frequently scraping down the bowl, until the frosting is smooth and well blended.
The frosting should be like whipped cream (light and fluffy).
