Ingredients

• 4 tablespoons All-purpose flour
• 2 tablespoons Granulated sugar
• 0.25 teaspoons Baking powder
• 0.25 teaspoons Ground cinnamon
• 1 pinch Salt
• 3 tablespoons Milk
• 1 tablespoons Vegetable oil
• 0.25 teaspoons Vanilla extract
• 1 tablespoons Brown sugar
• 0.5 tablespoons Unsalted butter
• 1 tablespoons Additional all-purpose flour (for streusel)
• 0.25 teaspoons Ground cinnamon (for streusel)

Directions

Step 1

In a small bowl, mix together the dry ingredients for the cake base: 4 tablespoons all-purpose flour, 2 tablespoons granulated sugar, 0.25 teaspoons baking powder, 0.25 teaspoons ground cinnamon, and a pinch of salt.

Step 2

Add the wet ingredients to the dry mixture: 3 tablespoons milk, 1 tablespoon vegetable oil, and 0.25 teaspoons vanilla extract. Stir until just combined. Do not overmix.

Step 3

Pour the batter into a clean, microwave-safe jar or mug, filling it no more than halfway to allow room for rising.

Step 4

In a separate small bowl, prepare the streusel topping by mixing 1 tablespoon brown sugar, 0.5 tablespoons unsalted butter (softened), 1 tablespoon additional all-purpose flour, and 0.25 teaspoons ground cinnamon. Use your fingers or a fork to create a crumbly texture.

Step 5

Sprinkle the streusel mixture over the batter in the jar.

Step 6

Microwave the jar on high for 1 minute and 30 seconds to 2 minutes, depending on the wattage of your microwave. Begin checking for doneness at the 1-minute-and-30-second mark by inserting a toothpick into the center—it should come out clean.

Step 7

Carefully remove the jar from the microwave (it will be hot!) and let the coffee cake cool for a minute or two before serving.

Step 8

Enjoy the cinnamon streusel coffee cake straight from the jar or transfer it to a plate if preferred.
