Easy Cinnamon Streusel Oatmeal Muffins Recipe

Do you have oatmeal fans at your house? My sons enjoyed it more when they were little but, will eat any kind of sweet treat that includes oatmeal. We all enjoy a freshly baked batch of oatmeal cookies and copycat oatmeal cream pies. Then, there’s a retro oatmeal cake with a broiled coconut pecan frosting that’s been a jewel on potluck tables in the South for eons. Oatmeal as an ingredient, holds a solid place among Southern desserts.

How to Make the Best Cinnamon Streusel Oatmeal Muffins

Ingredients you’ll need to make homemade Cinnamon Streusel Oatmeal Muffins: All purpose flour, quick cooking oats, light brown sugar, butter, baking powder, cinnamon, salt, buttermilk, vanilla extract and large eggs.
To make the cinnamon streusel you’ll need: All purpose flour, quick cooking oats, cinnamon and cold butter.
Kitchen tools you’ll need: Two medium bowls, measuring cups and spoons, rubber spatula, whisk, pastry blender and cupcake pan.
These muffins aren’t difficult to make at all. In fact, there’s no need to use a mixer for making the batter unless you want to.
I use buttermilk for these muffins as I almost always have it on hand, and it’s my personal preference. They can be made with whole milk or half and half in the same amount called for in the recipe.
How do you make buttermilk? To make homemade buttermilk, place 1 tablespoon of lemon juice or white distilled vinegar into a measuring cup. Fill it the rest of the way with the amount of milk called for in the recipe. Allow it to sit on the counter for 5-10 minutes, then proceed with the recipe.
You can use old fashioned or quick cooking oats in this recipe. I don’t recommend using instant oatmeal.
You could add a sprinkling of chopped pecans or walnuts to the streusel. When doing so 1/3 cup should be ample.
I’ve used pumpkin pie spice in place of ground cinnamon in this recipe from time to time. Pumpkin pie spice is a blend of cinnamon with the addition of ginger, nutmeg and cloves. Either one will work in the same amount.
Store baked Cinnamon Streusel Oatmeal Muffins in an airtight container chilled in the refrigerator or at room temperature for up to 3 days.
You an also freeze oatmeal muffins for up to 3 months.
