1-Getting started: with peanut butter and banana coffee cake is straightforward and fun. First, preheat your oven to 350°F and lightly grease a 10-inch springform pan to ensure easy removal later. In a small bowl, mix the flour, sugar, and cinnamon, then cut in the softened butter until it forms pea-sized crumbs; set this topping aside for now.

2-Next, in a large bowl, beat the peanut butter, oil, and granulated sugar until they blend smoothly. Add the eggs one at a time, beating well after each to incorporate air and create a fluffy batter. Stir in the mashed banana and vanilla extract for that signature flavor boost. In another bowl, whisk together the flour, baking powder, baking soda, and salt to evenly distribute the leavening agents.

3-Now, add half of the dry mixture to the wet ingredients and stir gently. Gradually pour in the milk, then mix in the rest of the dry ingredients until just combined, avoiding overmixing to keep the cake tender. Pour the batter into your prepared pan and sprinkle the topping evenly over it. Bake for 45 to 50 minutes, or until a toothpick inserted in the center comes out clean. Let the cake cool on a wire rack for about 30 minutes before slicing and serving; store leftovers in the fridge for freshness.
