Steps to Make Peanut Butter Crumb Cake
- Preheat the oven and grease a 9×13-inch baking pan.
- Combine flour, brown sugar, peanut butter, and butter until crumbly; reserve a cup of crumbs.
- Add baking powder, baking soda, milk, vanilla, and eggs to the remaining crumbs.
- Beat until smooth and well blended.
- Spread the batter in the pan.
- Sprinkle the reserved crumbs over the top.
- Add the chocolate chips evenly over the crumbs.
- Bake until the cake tests clean and the top is set and golden.
Tips
- Reserve the crumb mixture first — it forms the topping.
- Scrape the bowl as you mix to ensure even blending.
- Use room-temperature butter for the best crumb texture.
- Let the cake cool slightly before cutting for cleaner slices.
Recipe Variations
- Swap the chips. Use peanut butter chips, white chocolate, or a mix.
- Add nuts. Chopped pecans or peanuts give extra crunch.
- Warm spices. A little cinnamon or nutmeg adds a cozy fall twist.
- Streusel boost. Add a tablespoon of oats to the reserved crumbs for texture.
Serving Suggestions
- Serve warm or room temperature with cold milk or coffee.
- Add a dollop of whipped cream for dessert.
- Pair with fresh berries to cut the sweetness.
- Garnish with extra chocolate chips or chopped peanuts.
How to Store
Room temperature: Keep the cake tightly covered for up to 3 days. The brown sugar and peanut butter help it stay moist.
Refrigerate: Refrigeration isn’t necessary, but it will extend freshness by a day or two if your kitchen is warm.
Freeze: Freezes well for up to 2 months. Wrap individual pieces to prevent drying — high-fat cakes like this hold texture beautifully.
