Cinnamon Swirl

In a small bowl, combine the cold, cubed butter, brown sugar, and cinnamon.

Cut the butter into the sugar and cinnamon by squishing the pieces with your fingers. Mix until the butter is fully incorporated and the mixture resembles wet sand.

Place in the fridge until ready to use.

Streusel

In a medium bowl, combine the oats, sugars, and spices.

Add in the cubed cold butter and squish the pieces together with your fingers until it is fully incorporated.

Place in the fridge until ready to use.

Apple Cake

Preheat the oven to 350 degrees F (180 degrees C).

Line a 9"x9" pan with parchment paper long enough to hang over the sides for easy removal.

In a medium bowl, combine the flour, baking powder, baking soda, salt, cinnamon, nutmeg, allspice, cloves, and ginger. Set aside.

In a large measuring cup or medium bowl, whisk together the whole milk, yogurt, applesauce, and oil. Set aside.

In the bowl of a stand mixer fitted with a paddle attachment, beat the butter, brown sugar, and granulated sugar for 2-3 minutes.

Add in vanilla and eggs one at a time, allowing each to fully incorporate before adding the next.

In about 3 additions, alternate adding the dry and wet ingredients until everything is fully combined. Be sure to scrape the bottom of the bowl frequently.

Lastly, fold in the honeycrisp apples.

Pour half of the batter into the prepared square pan. Top with all of the cinnamon swirl mixture, then gently pour the rest of the batter on top. And the streusel on top and bake for about 1 hour to until a toothpick inserted comes out clean.

Allow cake to cool before removing from pan and adding the glaze.

Glaze

In a small bowl, mix together the powdered sugar, yogurt, and milk until smooth.

Drizzle on top of cooled cake and serve!

Tips & Tricks (5)

Prep Apples Just Before Assembly 🍎
Toss freshly diced Honeycrisp apples with lemon juice and cinnamon immediately before folding into batter to prevent browning and maintain their bright flavor and firm texture throughout baking.
Toast Oats for Deeper Streusel Flavor 🌾
Lightly toast your quick cooking oats in a dry pan for 2-3 minutes before mixing into the streusel topping to develop a rich, nutty flavor that elevates the entire cake.
Use Cold Butter for Perfect Streusel Texture ❄️
Keep butter cubed and chilled when making the streusel mixture, then work it in with your fingertips until crumbly to create those desirable cookie-like clusters rather than a dense topping.
Bloom Spices in Oil First 🤎
Combine your warm spices (cinnamon, ginger, cloves, nutmeg, allspice) with the oil before adding to wet ingredients to activate their essential oils and distribute flavor more evenly throughout the cake.
Test Doneness at Cake Center, Not Apple Layer 🔍
Insert your toothpick into the actual cake portion between apple pieces rather than through the apples themselves, as apples retain moisture longer and can give a false indication of doneness.
