Cinnamon Streusel Coffee Cake

Soft and tender coffee cake with a sweet cinnamon swirl and buttery crumb topping. Coffee cake, most of the time, does not actually contain any coffee! It refers to a buttery sweet, slightly dense cake that is usually baked in a single layer round or square pan, or even a bundt pan. It often can have a crumble topping or crumble swirl through the middle.

1/4 cup 56g unsalted butter softened
1/4 cup 60ml sunflower oil
3/4 cup 150g granulated sugar
1/2 teaspoon 5ml pure vanilla extract
1/4 teaspoon almond extract
1 large egg
1 2/3 cups 235g all-purpose flour
1/4 cup 25g almond flour
2 teaspoon baking powder
1/2 teaspoon salt
2/3 cup 150ml milk

Filling & Topping:
1/2 cup 71g all-purpose flour
1/2 cup 110g packed light brown sugar
1 1/2 teaspoon ground cinnamon divided
3 tablespoon 42g unsalted butter, softened
1/8 teaspoon salt

For the topping, combine flour, brown sugar, 1 teaspoon of cinnamon and salt until blended. Reserve 1/4 cup of this mixture and place in a separate bowl and stir in another 1/2 teaspoon of cinnamon – this will be the filling. Add butter to the main mixture and blend until it makes clumps – this will be the topping.

Preheat the oven to 350F. Line an 8x8-inch baking pan with parchment paper.

Sift flour, baking powder, and salt into a medium bowl. Add almond flour and whisk to blend evenly.

Combine soft butter, sugar, oil, vanilla and almond extracts in a large bowl and beat with an electric hand mixer until pale and fluffy. Beat in egg until evenly incorporated. Add half of the flour mixture and mix on low then alternate adding milk and dry ingredients while mixing on low until just combined.

Dollop just over half of the batter into prepared pan and spread it out evenly. Sprinkle the filling mixer evenly over top. Then take spoonfuls of the remaining batter and dollop over the filling and spread it out disturbing the filling layer as little as possible (an offset spatula works well for this). Use an offset spatula to gently spread it over to cover the filling.

Take the topping mixture in clumps and crumble it over the batter. Bake for 25-30 minutes until a skewer comes out clean.
