Preheat your oven to 350°F. In a large mixing bowl, use a rubber spatula to blend the butter substitute with the sugar. Whisk the eggs separately, then add them to the mix. Stir in the vanilla and applesauce until fully combined.

Stir in the yogurt, salt, baking powder, and baking soda until the mixture is smooth. Gradually fold in the flour, mixing gently until the batter forms. Avoid overmixing to keep the cake light and fluffy.

Prepare the Oat Topping

In a medium saucepan, heat the honey and then add the oats, cinnamon, and any additional topping ingredients. Stir to coat the oats evenly with the honey and cinnamon. Once the mixture is crumbly, remove it from heat. Add small amounts of water if needed to reach the right texture.

Assemble the Cake

Variations and Substitutions

You can easily adapt this coffee cake recipe to suit your preferences. To make Coffee Cake Muffins, divide the batter into a muffin pan and reduce the baking time, topping each portion with the crumb mixture. For a more classic version, try Coffee Cake with Streusel Topping by swapping out the oat topping for a traditional streusel. You can also make the cake lower in points by replacing regular sugar with a 1:1 ratio of zero-calorie sweetener, though it may require a longer bake time. If you’re looking to reduce points even further, experiment with using applesauce in place of a butter substitute, but consider adding less applesauce at first to avoid altering the cake’s texture too much. Finally, elevate your coffee cake by adding a simple glaze made from powdered sugar and a bit of milk or water for a polished finish.

Tips and Tricks for Making Brown Sugar Cinnamon Oat Coffee Cake

Here are some helpful tips for making Brown Sugar Cinnamon Oat Coffee Cake. When preparing the oat topping, be careful not to overcook it on the stovetop—just melt the honey enough to coat the oats evenly. Over-toasting the oats can lead to burning in the oven. For easy cleanup, spray your measuring spoon with avocado oil before measuring honey so it doesn’t stick. To ensure the topping stays on top of the cake rather than sinking, sprinkle a little flour on the batter before adding the oats. Check the cake’s doneness by inserting a toothpick or knife into the center—it should come out clean. Store leftovers tightly wrapped for up to 3 days at room temperature or extend its freshness by refrigerating for up to 5 days.
