Easy Steps to Baking Perfection

Making this easy coffee cake is straightforward. Follow these steps for a perfect bake every time:


  1. Preheat & Prep: Preheat your oven to 350°F (175°C). Grease and flour an 8x8 inch square baking pan, or spray generously with non-stick cooking spray.

  2. Mix Wet Ingredients: In a large bowl, stir together the melted coconut oil, eggs, granulated sweetener, and vanilla extract until well combined. Gently fold in the cooked oatmeal.

  3. Combine Dry Ingredients: In a separate medium bowl, whisk together the flour(s), ground cloves, salt, ground cinnamon, and baking soda.

  4. Combine Wet and Dry: Add the dry ingredient mixture to the wet ingredient mixture. Stir gently until just combined – be careful not to overmix.

  5. Pour Batter: Pour the batter evenly into the prepared 8x8 inch pan.

  6. Make Topping: In a small bowl, mix the 1 tablespoon of coconut oil, chopped pecans, and brown sugar until crumbly.

  7. Add Topping & Bake: Sprinkle the pecan streusel topping evenly over the cake batter. Bake in the preheated oven for 25-30 minutes, or until a wooden skewer or toothpick inserted into the center comes out clean.

  8. Cool & Serve: Let the oatmeal coffee cake cool in the pan for at least 10-15 minutes before cutting into squares. Serve warm or at room temperature. Enjoy!

Tips and Variations

  • Oatmeal Prep: Use plain cooked oatmeal (rolled oats or quick oats work). Ensure it's cooled before adding to the batter.

  • Flour Choice: Using half white whole wheat flour adds a bit more fiber and a slightly nuttier taste, but using all all-purpose flour works perfectly fine too.

  • Oil Substitute: You can substitute melted butter or a neutral vegetable oil for the coconut oil if preferred.

  • Nut-Free: Omit the pecans from the topping for a nut-free version. You could add more oats or cinnamon to the topping instead.

  • Storage: Store leftover coffee cake in an airtight container at room temperature for up to 3 days.


This coffee cake with oatmeal is more than just a breakfast cake recipe; it's a comforting hug in cake form. Its moist texture and delicious flavor make it a standout recipe perfect for any occasion.
