Will I feel anything from this much butter in this recipe?

I'm very new to edibles, and I had tea last night that had tbsp and half a g, and it got me hard. I am now working on making butter, and it is two sticks and a 1/4. I want to make donuts, and it calls for two tbsp of butter for 12 donuts. Will that do anything? If I doubled the butter, would it ruin the recipe? Here is the recipe too:
2 cups all-purpose flour
1 1/2 cups sugar
2 teaspoons baking powder
1 teaspoon ground cinnamon
1/2 teaspoon ground nutmeg
1/2 teaspoon kosher salt
1 extra-large egg, lightly beaten
1 1/4 cups whole milk
2 tablespoons unsalted butter, melted
2 teaspoons pure vanilla extract
